Foreword

The U.S. Environmental Protection Agency (EPA) Office of Research and Development (ORD) and the
Centers for Disease Control and Prevention (CDC) Agency for Toxic Substances and Disease Registry
(ATSDR) have worked collaboratively to complete the research activities on synthetic turf playing fields
under the "Federal Research Action Plan on Recycled Tire Crumb Used on Playing Fields and
Playgrounds" (FRAP). The Agencies have released the research activities' results in two parts. The Part
1 Report (U.S. EPA & CDC/ATSDR, 2019) summarizes the research effort to characterize tire crumb
rubber, which includes characterizing the components of, and emissions from, recycled tire crumb
rubber. The exposure characterization report (Part 2 - this report) summarizes the potential exposures
that may be experienced by users of synthetic turf playing fields with recycled tire crumb rubber infill,
such as how people come in contact with the materials, how often and for how long. It includes the
results from a supplemental biomonitoring study conducted by CDC/ATSDR. This Part 2 exposure
characterization report completes FRAP efforts with respect to playing fields.

The study is not a risk assessment; however, the results of the research described in the FRAP reports
will advance our understanding of exposure to inform the risk assessment process. We anticipate that the
results from this multi-agency research effort will be useful to the public and interested stakeholders to
understand the potential for human exposure to chemicals found in recycled tire crumb rubber used on
synthetic turf fields.

This report has been prepared to communicate to the public the research objectives, methods, results and
findings for the exposure characterization research conducted as part of the Federal Research Action
Plan. The report has undergone independent, external peer review in accordance with EPA and CDC
policies. A response-to-peer review comments document accompanies the release of the Part 2 report.

The mission of the EPA is to protect human health and the environment so that future generations inherit
a cleaner, healthier environment that supports a thriving economy. Science at EPA provides the
foundation for credible decision-making to safeguard human health and ecosystems from environmental
pollutants. ORD is the scientific research arm of EPA, whose leading-edge research helps provide the
solid underpinning of science and technology for the Agency. ORD supports six research programs that
identify the most pressing environmental health research needs with input from EPA offices, partners
and stakeholders.

CDC works 24/7 to protect America from health, safety and security threats, both foreign and in the
United States. ATSDR is a non-regulatory, environmental public health agency that was established by
Congress under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980.
ATSDR protects communities from harmful health effects related to exposure to natural and man-made
hazardous substances by responding to environmental health emergencies; investigating emerging
environmental health threats; conducting research on the health impacts of hazardous waste sites; and
building capabilities of and providing actionable guidance to state and local health partners.

1. Executive Summary

In 2016, the Centers for Disease Control and Prevention/Agency for Toxic Substances and
Disease Registry (CDC/ATSDR) and the U.S. Environmental Protection Agency (EPA), in
collaboration with the Consumer Product Safety Commission (CPSC), launched a multi-agency
research effort known as the Federal Research Action Plan on Recycled Tire Crumb Used on
Playing Fields and Playgrounds (FRAP). To address the public's concerns about the use of
recycled tire crumb rubber on synthetic turf fields, the FRAP focused on assessing potential
human exposure, which includes conducting research activities to characterize the chemicals
associated with recycled tire crumb rubber and to identify the ways in which people may be
exposed to those chemicals based on their activities on synthetic turf fields [EPA and
CDC/ATSDR 2019],

In 2022, CDC/ATSDR conducted a biomonitoring study to supplement the FRAP's pilot-scale
human exposure study conducted in 2017 [EPA and CDC/ATSDR 2024]. This report summarizes
key findings as they relate to the following objectives:

•	Objective 1: Expand upon the FRAP's pilot-scale study by including a larger sample size
of synthetic turf with recycled tire crumb rubber infill users and a comparison group of
natural grass field users.

•	Objective 2: Examine potential associations in pre- and post-activity urinary polycyclic
aromatic hydrocarbon (PAH) metabolite concentrations with field type (i.e., synthetic
turf fields with recycled tire crumb rubber infill and natural grass fields).

•	Objective 3: Compare study participants' urinary concentrations to those found in the
noninstitutionalized general U.S. population using National Health and Nutrition
Examination Survey (NHANES) data.

CDC/ATSDR's biomonitoring study included questionnaire administration to participants and
the collection of pre- and post-activity urine sampling. Results compiled from a total of 161
study participants aged between 7-77 years are included in this report. The 7 urinary PAH
metabolites assessed at the CDC National Center for Environmental Health (NCEH) Division of
Laboratory Sciences (DLS) included: 1-hydroxynaphthalene (1-NAP), 2-hydroxynaphthalene (2-
NAP), 2-hydroxyfluorene (2-FLU), 3-hydroxyfluorene (3-FLU), 1-hydroxyphenanthrene (1-PHE),
1-hydroxypyrene (1-PYR), and the sum of 2-hydroxyphenanthrene and 3-hydroxyphenanthrene
(2 & 3-PHE).

Notably:

•	Pre- and post-activity differences in urinary PAH concentrations were not associated
with field type (i.e., synthetic turf with recycled tire crumb rubber infill and natural grass
fields).

•	Pre- and post-activity differences in urinary PAH concentrations varied by statistical
method and urinary dilution adjustment (i.e., specific gravity, creatinine) method.

1


-------
•	The best predictor of post-activity urinary PAH concentration was pre-activity
concentration.

•	Except for 2-NAP, pre-activity PAH concentrations were lower than those in the general
U.S. population (NHANES 2015-2016).

These results indicate recycled tire crumb rubber infill users and natural grass field users
experienced similar differences in pre-and post-activity PAH concentrations. Importantly,
CDC/ATSDR's biomonitoring study as detailed in this report is not a risk assessment. However,
combined with the initiatives of the FRAP, this study's findings contribute to the extensive
research portfolio regarding the use of tire crumb rubber infill in playing fields.

2. Introduction

There are more than 12,000 synthetic turf fields installed in the United States [STC et al. 2016].
Millions of people use and/or work at these synthetic turf fields across a range of settings,
including municipal and county parks; schools, colleges, and universities; professional sports
stadiums and practice fields; and military installations. Approximately 95% of synthetic turf
fields utilize small pieces of recycled tire ("recycled tire crumb rubber") either as infill
exclusively or in mixture with sand or alternative infills [STC et al. 2016]. Tires are manufactured
with a range of chemicals; additionally, tires may also pick up and absorb chemicals over their
lifetime of use and serve as a sorbent for chemicals in the air and dust [EPA and CDC/ATSDR
2019]. Users of synthetic turf fields with recycled tire crumb rubber infill can potentially be
exposed to chemicals such as polycyclic aromatic hydrocarbons (PAHs) in a variety of ways,
including while breathing (i.e., inhalation exposure), contacting the material with their skin (i.e.,
dermal exposure), and by ingesting the material (i.e., ingestion exposure) [EPA, CDC/ATSDR,
and CPSC 2016; EPA and CDC/ATSDR 2019],

Parents, athletes, schools, and communities have raised concerns about the safety of recycled
tire crumb rubber used as infill for playing fields and playgrounds. To fill important data gaps
and address key environmental and human health questions regarding the use of recycled tire
crumb rubber, the Centers for Disease Control and Prevention/Agency for Toxic Substances and
Disease Registry (CDC/ATSDR), U.S. Environmental Protection Agency (U.S. EPA), and U.S.
Consumer Products and Safety Commission (CPSC) launched the Federal Research Action Plan
on Recycled Tire Crumb Used on Playing Fields and Playgrounds (FRAP) in 2016.1 Key activities
since performed as part of the FRAP included: a literature review and data gaps analysis [EPA,
CDC/ATSDR, and CPSC 2016]; a tire crumb rubber characterization study [EPA and CDC/ATSDR
2019]; and a human exposure characterization study [EPA and CDC/ATSDR 2016 Research
Protocol; EPA and CDC/ATSDR 2024],

The primary aims of the human exposure characterization research study were to (1) collect
human activity data for synthetic turf field users that will reduce the reliance of default
exposure factor assumptions in exposure and risk assessment; and (2) conduct an exposure
measurement sub-study for people using synthetic turf fields with tire crumb rubber infill, in

what are likely to be among the higher exposure scenarios to improve understanding of
potential exposures, particularly for the dermal and ingestion exposure pathways [EPA and
CDC/ATSDR 2016 Research]. To meet these objectives, CDC/ATSDR and U.S. EPA collaborated
on a pilot-scale human exposure characterization study among field users of synthetic turf with
tire crumb rubber infill (Office of Management and Budget [OMB] Control No. 0923-0058). The
pilot-scale study involved questionnaire administration and several types of sample collection,
including field environment samples, personal samples (air, dermal wipes), and biological
samples (urine and blood pre-activity and post-activity). The sample size for biological
measurements was small: 14 participants provided urine samples and 13 provided blood
samples. Urine samples were analyzed for 7 PAHs and serum samples derived from the blood
samples were analyzed for metals. Results from the pilot-scale study are detailed in the FRAP
Part 2 Report [EPA and CDC/ATSDR 2024],

In spring and summer 2022, CDC/ATSDR conducted participant recruitment for a supplemental
biomonitoring measurements study regarding exposure during activities performed on
synthetic turf fields with tire crumb rubber infill (OMB Control Number: 0923-0062). The design
of this study addressed limitations of the 2017 pilot study, including the small sample size of
participants and a lack of a comparison population. CDC/ATSDR's supplemental biomonitoring
study included questionnaire administration and pre- and post-activity urine sampling among
users of synthetic turf fields with tire crumb rubber infill and users of natural grass fields. Data
collection efforts were consistent with those in the original pilot study's research protocol [EPA
and CDC/ATSDR 2016 Research Protocol] but modified in scope (i.e., questionnaire
administration and urine sampling but no blood sampling) to achieve the following objectives:

Objective 1: Expand upon the pilot-scale study by including a larger sample size of synthetic turf
with recycled tire crumb rubber users and a comparison group of natural grass field users.

Objective 2: Examine potential associations in pre- and post-activity urinary PAH metabolite
concentrations with field type (i.e., synthetic turf fields with recycled tire crumb rubber infill
and natural grass fields).

Objective 3: Compare study participants' urinary PAH concentrations to those found in the
noninstitutionalized general U.S. population using National Health and Nutrition Examination
Survey (NHANES) data.

3. Methods

3.1. Recruitment

Study participants were recruited from 3 athletic facilities (2 outdoor and 1 indoor, as shown in
Figure 1) in two U.S. census regions2 during April-September 2022. The two outdoor facilities

2The U.S. census regions are four geographic groupings of states that subdivide the United States, including:
Midwest (Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, South
Dakota, and Wisconsin); Northeast (Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, New York,

consisted of synthetic turf fields with tire crumb rubber infill co-located with natural grass
fields. The single indoor facility consisted of a synthetic turf field with tire crumb rubber infill. At
the time of study recruitment, the indoor field with recycled tire crumb rubber infill was
approximately 4 years old, while the 2 outdoor synthetic turf fields with recycled tire crumb
rubber infill were approximately 8 and 9 years old. Natural grass field users served as a
comparison group for examining the potential association between pre- and post-activity PAH
concentration differences with field type. The synthetic turf fields were previously included in
the tire crumb characterization research activity of the FRAP (OMB Control No. 0923-0054).

Eligible study participants included a convenience sample of field users ages 7 years and older
who engaged in physical activity on the synthetic turf fields with recycled tire crumb rubber or
natural grass fields. Exclusion criteria included those who self-reported smoking or living in a
household with someone who smokes. Additionally, natural grass participants were excluded if
they indicated playing on synthetic turf with tire crumb rubber infill in the past 24 hours. Field
users were asked to complete a study questionnaire and provide both pre- and post-activity
urine samples.

of informed consent was in place, the only record linking the participants to the research was a
consent document and study ID; no names or other personally identifiable data were
collected.3 A two-year extension for the research study was granted due to delays encountered
with the COVID-19 pandemic.

3.2. Data Collection

3.2.1.	Questionnaire Administration

Questionnaires were administered to eligible field users on the date of urine sampling
collection to obtain information on participant activity patterns that could affect the duration
or frequency of their potential exposures. Participants were informed the questionnaire would
take about 30 minutes to complete. Depending on the age of the participant, slightly different
questionnaire versions were used for administration either directly to participants ages 13
years or older, or to a parent or guardian of participants ages 7-12 years. Questionnaire items
also included non-activity-related factors that could affect PAH concentrations, such as
demographics (e.g., age, gender, and race), mode of commute to the field, and consumption of
grilled foods in the past 24 hours, among others.

3.2.2.	Urine Sample Collection and Processing

Both pre- and post-activity urine samples were collected to control for baseline body burden
levels and adjust for the effects of metabolic processes to better isolate the effects of activity
and potential exposure related to recycled tire crumb rubber infill. Consistent with the FRAP
pilot study protocol for urine collection, preparation, and storage procedures, participants were
provided with a sealed sterile urine collection cup to provide urine samples on-site using either
facility restrooms or port-a-potties. Samples were shipped on dry ice to the CDC National
Center for Environmental Health (NCEH) Division of Laboratory Sciences (DLS) for measurement
of PAH metabolites, specific gravity, and creatinine concentrations. In alignment with the CDC
NHANES panel [CDC 2020], 7 PAH metabolites were quantified using online solid phase
extraction high performance liquid chromatography/tandem mass spectrometry (SPE-HPLC-
MS/MS) [Wang 2017]. The PAH metabolites included 1-hydroxynaphthalene (1-NAP), 2-
hydroxynaphthalene (2-NAP), 2-hydroxyfluorene (2-FLU), 3-hydroxyfluorene (3-FLU), 1-
hydroxyphenanthrene (1-PHE), 1-hydroxypyrene (1-PYR), and the sum of 2-
hydroxyphenanthrene and 3- hydroxyphenanthrene (2 & 3-PHE).4

Measurement Supplemental Study Materials and questionnaires are available at:
https://www.reginfo.gov/public/do/PRAViewlCR7ref nbr=202106-0923-001.

Consistent with NHANES, 2-3-PHE values are comparable to the sum of urinary levels of 2-hydroxyphenanthrene
and 3-hydroxyphenanthrene. Additional information is available at: https://wwwn.cdc.gov/Nchs/Nhanes/2013-

3.3. Data Analysis

3.3.1.	Specific Gravity and Creatinine Adjustments

To account for the effect of urinary dilution and facilitate comparisons with data produced from
other studies, all urinary PAH metabolites were adjusted for specific gravity and creatinine. The
outcome variables in this analysis were urinary PAH metabolite concentrations, their specific
gravity and creatinine adjusted values, and In-transformed versions of each.

Urine specific gravity (SG) was measured and used to adjust PAH concentrations for urine
dilution according to the formula,

^sg - ^measured x (1.0194 - l)/(p - 1),

where Cmeasured W3S the individual observed urine PAH concentration, p was the individual
observed SG, and 1.0194 was the average SG of all urine samples in this study [Alhamdow
2017],

Creatinine (CRE) was used to adjust PAH concentrations using the ratio method according to
the formula,

^-Ratio — ^-measured /CRE

where Cmeasured W3S the individual observed urine PAH concentration and CRE was the
corresponding creatinine concentration.

3.3.2.	Covariates

Covariate data was collected from a questionnaire administered at the time of sample
collection. Categorical variables used in this analysis were age category (children [7-9 years],
youth [10-12 years], adolescent [13-17 years], adult [18+ years]); sex (male, female); Hispanic
ethnicity (Hispanic, Non-Hispanic); race (Asian, White, Other [Non-Hispanic participants who
indicated Black, Native Hawaiian/Other Pacific Islander, multiple races, or did not report race]),
field type (natural grass or synthetic turf), field environment (indoor or outdoor); consumption
of grilled, barbequed, smoked, or deep fried food in the last 24 hours (yes or no); facility
location by U.S. census region (i.e., South or West); activity (e.g., lacrosse, soccer, other); BMI
categories (underweight, normal, overweight, and obese; with cut points at <18.5, <25, <30,
and >=30, respectively, for adults).5

5CDC growth charts were used to calculate BMI for participants <20 years old with cut points defined at BMI
percentages (0,5), [5,85), [85,95), and 95+. Because age was only collected for whole years and age-in-months is
required to properly use growth charts, BMI calculations for participants under 20 years old were subject to
misclassification due to rounding. See SAS Program for CDC Growth Charts. See:
https://www.cdc.gov/nccdphp/dnpao/growthcharts/resources/sas.htm.

-------
Continuous variables used in the analysis included PAH concentrations, specific gravity
concentrations, creatinine concentrations, age (rounded to whole years), height, weight,
number of months that a participant reported having used a field, and time (minutes) spent
commuting to the field on a typical day.

Various measures were calculated to assess the probability distributions of PAH concentrations;
this included distribution plots, Q-Q plots, a statistical test of normality (Shapiro-Wilk test),
calculated distribution measures such as kurtosis (a measure of the heaviness of a distribution's
tail) and skewness (a measure of the asymmetry of a distribution). Regression of non-
transformed concentrations can result in statistical associations solely attributable to outliers
and generally do not meet the assumptions of common statistical methods, such as normality.
Ln-transformation serves to lessen the influence of large concentrations that are typical of log-
normally distributed biomarker data. Distribution plots and tests of normality (data not shown)
indicated that the PAH concentrations were approximately log-normally distributed. Based on
these assessments, PAH concentrations were In-transformed for regression analyses.
Specifically, the difference of the individual In-transformed pre- and post-activity data were
examined, which is equivalent to the In of the ratio of concentrations on the original scale:

In(post) - ln(pre)= ln(post/pre)

3.3.3.	Statistical Analysis

Analyses were conducted in SAS software, version 9.4 LTS Level 1M7 of the SAS System for
Windows. Copyright (c) 2002-2012 by SAS Institute Inc., Cary, NC, USA. Proc SGPLOT and
SGPANEL were used to create plots for data visualization; Procs TTEST and UNIVARIATE were
used to assess pre- and post-activity changes in PAH concentration; and Proc GLM was used to
investigate statistical associations between pre- and post-activity differences in PAH
concentration with covariates that were selected a priori based on their potential association
with PAH concentrations.

Regression modeling focused on three dependent variables: pre-activity, post-activity, and
differences between pre- and post-activity concentrations. The key independent variable was
field type (synthetic turf vs. natural grass), and models were adjusted for covariates. General
linear models were used to test whether variables such as field type were associated with
observed pre- and post-activity differences in concentrations (defined as post concentration
minus pre concentration). In these models, the intercept tested whether there was an overall
difference between pre- and post-activity mean concentrations. Additionally, the beta
coefficient for a covariable measured whether there was a difference in pre- and post-activity
differences between levels of the covariate. The focus of this investigation was the potential
association between field type (synthetic turf or natural grass) and increased PAH
concentration, post-activity.

3.3.4.	PAH Metabolite Comparisons to the General U.S. Population

Study participants' urinary PAH metabolite concentrations were compared to those among the
non-institutionalized U.S. population by age group using NHANES data from 2015-2016 and

7


-------
2007-2008. The 2015-2016 NHANES cycle was the most recent cycle to contain PAH
concentrations. Because specific gravity was not measured in the 2015-2016 cycle, only
unadjusted and creatinine-adjusted concentrations could be compared. Pre-activity
concentrations from this study were used for comparison, as NHANES participants did not
engage in physical activity prior to specimen collection, and post-activity concentrations among
this present study's participants were likely affected by hydration changes. The 2007-2008
cycle was used to compare the present study's specific gravity adjusted PAH metabolite
concentrations; this was the only cycle that measured both creatinine and specific gravity.

4. Results

4.1.	Study Population and Urine Sample Properties

A total of 172 participants were recruited for the study, among whom all provided
questionnaires and 171 provided pre- and/or post-activity urine samples. Among the 171
participants, a total of 10 participants were excluded from the analysis due to at least one of
the following factors: missing post-activity urine sampling (n=4), shipping-related delays of
urine samples which might have compromised sample integrity (n=3), or flagged upon sample
processing (n=3). Thus, 10 participants were excluded, leaving a total of 161 participants who
were included in this analysis. Finally, one participant had an interfering substance code for 1-
NAP, but valid measurements for all other analytes, and so the analysis sample size for 1-NAP
specifically was reduced to 160 participants. All participants were recruited in the evening or
afternoon due to activity schedules. Participants spent an average of 1 hour and 39 minutes
(range: 40 minutes to 2 hours and 58 minutes) between pre- and post-urine collections.

In total, 6% of PAH measurements were below the limit of detection (LOD). Specifically, 134 of
2252 PAH measurements (160 participants x 7 analytes x 2 measurements + 1 participant x 6
analytes x 2 measurements) were below the LOD. Four of these PAH measurements had a zero
value and were replaced by the limit of detection (LOD) divided by a/2; four creatinine
measurements that had missing values due to being less than the lowest standard were also
replaced by the LOD divided by a/2. Non-zero values below LOD were unchanged.

4.2.	Study Population Description

Table 1 presents the characteristics of the study participants. As shown, among the 161 study
participants, a total of 82% (n=132) played on synthetic turf with tire crumb rubber infill and
the remaining 18% (n=29) on natural grass. Moreover, 25% of study participants used an indoor
field of synthetic turf with tire crumb rubber infill, and all other participants utilized outdoor
fields. Across the three facilities and two U.S. census regions, 68% of the study participants
were recruited from the South and 32% from the West. The study population for this analysis
comprised 27% female and 73% male, with an age range of 7 to 77 years and a median age of
14 years at the time of specimen collection. Ages were distributed as approximately 15%
children (7-9 years), 17% youth (10-12 years), 32% adolescent (13-17 years), and 37% adult (18+

8


-------
years).6 By race, 63% of participants identified as White persons; 14% as Asian persons; and
23% as Black persons, Native Hawaiian or Pacific Islander persons, persons of multiple races, or
did not report race. By ethnicity, approximately 28% of participants identified as Hispanic or
Latino persons. The most common field activity was soccer (74%), followed by lacrosse (17%),
with various other activities (e.g., football, flag football, field hockey) making up the remaining
9%. By BMI, 60% of participants had a normal BMI, 20% had an overweight BMI, 10% had an
obese BMI, and 5% had an underweight BMI. As noted in the footnote above, because BMI
calculations for those under age 20 years depend on age-in-months, and because age was only
collected to the nearest whole year, these BMI results may be subject to misclassification. All
study participants reported having travelled to the facilities by car, with a median commute
time of 20 minutes. Responses to the question, "how long have you been coming to this
facility?" ranged from 0 to 120 months. Moreover, 33% of study participants reported having
eaten grilled, barbequed, smoked, or deep-fried food within the 24 hours prior to sample
collection.

4.3. Pre- and Post-Activity PAH Concentration Differences

As shown in the representative figures for 1-NAP (Figure 2). most study participants' PAH
concentrations increased post-activity after adjustment for specific gravity (left). However, the
equivalent result for creatinine ratio adjustment demonstrated a more even distribution
between those whose concentrations increased compared to those whose concentrations
decreased (right). Moreover, the identification of the participants who had the largest post-
minus pre-activity degree of change in concentrations was dependent upon the adjustment
method. The participants identified as having the biggest increases (when based on specific
gravity adjustment) played on natural grass, whereas those identified based on creatinine
adjustment played on synthetic turf (see Supplemental Figures Sl-1 through Sl-6 for additional
plots). As shown later in this report, these differences in post- and pre-activity PAH
concentrations were not associated with field type.

Figure 2. Difference in post- and pre-activity concentration for 1-hydroxynapthalene
measurements, In-transformed, by participant and field type. Specific gravity-adjusted (left)
and creatinine-adjusted (right).

Study Participant	Study Participant

| Field Type ¦ Natural Grass ¦ Synthetic Turf]	| Field Type ¦ Natural Grass ¦ Synthetic Turf]

Statistical differences in pre- and post-activity body burden levels for urinary PAHs are
presented for specific gravity-adjusted concentration differences by all participants (Table 2)
and by field type (Table 3). Additionally, statistical differences in pre- and post-activity body
burden levels for urinary PAHs are presented for creatinine-adjusted concentration differences
by all participants (Table 4) and by field type (Table 5). For specific-gravity adjusted and In-
transformed PAH concentrations, there was a statistically significant difference in mean
concentrations when comparing pre- and post-activity differences for all 7 PAHs (p-values
<0.05). However, this was irrespective of whether participants played on synthetic turf with tire
crumb rubber infill or natural grass fields. Fewer differences were observed when examining
creatine-adjusted and In-transformed PAH concentrations; pre-and post-activity concentration
differences were statistically significant for 1-PYR (mean: -1.76 [ig/L, p<0.Q5) and 2-NAP (mean:

11


-------
0.163 |-ig/L, p<0.05). As with the specific gravity-adjusted results, differences observed with
creatinine-adjusted data were irrespective of whether participants played on synthetic turf with
tire crumb rubber infill or natural grass fields. Statistical analysis of differences by additional
measures are displayed in Supplemental Tables Sl-1 through Sl-7 (specific gravity-adjusted)
and Supplemental Tables S2-1 through S2-7 (creatinine-adjusted).

Generally, pre- and post-activity concentrations were correlated. Specifically, the pre- and post-
activity correlations of the urinary PAH metabolites ranged from 0.81 to 0.85 for specific
gravity-adjusted concentrations, and 0.76 to 0.86 for creatinine-adjusted concentrations. This
was consistent overall and by age group.

4.4. Univariate Regression Modelling

Univariate general linear model (GLM) regression parameter estimates for differences in pre-
and post-activity concentrations by field type were examined using specific gravity-adjusted
(Table 6) and creatinine-adjusted (Table 7) data among participants with non-missing covariate
data (n=156). For all urinary PAHs, differences in pre- and post-activity concentrations could not
be explained by field type. Overall, mean differences between pre- and post-activity
concentration were statistically significant for specific gravity-adjusted results, but not
statistically significant for creatinine adjusted-results. Regardless of adjustment method,
however, these differences were not associated with field type in the univariate analyses.

4.5. Full Model Multivariable GLM Regression

The first step taken prior to conducting multivariable regression was to address concerns about
the potential for collinearity and data separation. For this study, all natural grass fields were
located outdoors and co-located with outdoor synthetic fields; thus the field environment
variable (indoor vs. outdoor) was also a measure of field type (synthetic turf vs. natural grass).
All indoor participants were recruited from the same field, and thus the same location (U.S.
Census Region; South or West). All volleyball players were female and recruited from the same
outdoor facility, and thus the same region. For these reasons, a new variable containing
mutually exclusive categories was generated and tested against models with individual
variables; models with individual variables performed best.

As an additional exploratory step, auto-selection algorithms were used to identify variables
associated with pre-activity, post-activity, and differences of concentrations as the dependent
variable in multivariable models for specific gravity-adjusted and creatinine-adjusted data (data
not shown). Field type was not statistically significant in any of the models of pre-and post-
activity differences in concentration. For both specific gravity- and creatinine-adjusted results,
the best predictor of post-activity concentration was the study participant's pre-activity
concentration; this was consistent with the earlier finding that pre- and post-activity
concentrations were highly correlated.

Multivariable GLM regression parameter estimates for differences in pre- and post-activity
concentrations by field type, adjusted for all other previously described variables are described
in Table 8 (specific-gravity adjusted) and Table 9 (creatinine-adjusted). As with the univariate
analysis, the difference in pre- and post- concentrations were not associated with field type.

4.6. Comparison to NHANES PAH Concentrations

Pre-activity PAH concentrations among study participants were compared to values in the
general U.S. population using secondary analysis of publicly available NHANES data. To facilitate
these comparisons, PAH concentrations were adjusted for specific gravity or creatinine
concentration. Specific gravity was only collected in the 2007-2008 NHANES cycle, whereas
creatine was collected in all NHANES cycles including the most recent cycle available (2015-
2016) at the time of data analysis. 2-3 PHE was not available in 2007-2008 NHANES.

Comparison of this study's specific gravity-adjusted results to those of the 2007-2008 NHANES
cycle may not be entirely comparable due to the observed trend of decreasing concentrations
over time for most PAHs. In NHANES, PAH concentrations markedly decreased over time,
except for 2-NAP where creatinine-adjusted geometric mean concentrations were 3.88 (5.45-
4.26) |ag/gCRE in 2007-2008 and 5.35 (4.86-5.90) |ag/gCRE in 2015-2016 (Supplemental Table
S3). Additionally, pre-activity PAH geometric mean concentrations of study participants were
lower than corresponding NHANES values except for adjusted 2-NAP concentrations (Figure 3).
Additional stratifications by age category and NHANES 2015-2016 PAH comparison values are
displayed in Table 10. This observation was consistent by age category except youth, where
concentrations were 4.97 (3.49-7.09) |ag/gCRE among youth in the study compared to 5.22
(4.24-6.44) |ag/gCRE among youth in NHANES 2015-2016, indicating no significant difference.

5. Discussion

Synthetic turf with recycled tire crumb rubber infill contains many substances, including PAHs
[Armada 2021; Gomes 2021; Marsili 2014; Murphy 2022; US EPA and ATSDR 2019], PAHs are a
large class of widespread chemicals generally produced during the incomplete burning of
organic substances, such as coal, oil and gas, garbage tobacco, and charbroiled meat [ATSDR
1995]. Routes of PAH exposure include ingestion, inhalation, and dermal contact both in
occupational and non-occupational settings [ATSDR 1995]. Once inside the body, PAHs are
metabolized by the liver into monohydroxylated metabolites and excreted rapidly in urine and
feces with half-life in the human body of less than 30 hours (Hudson-Hanley). Therefore,
urinary PAH metabolites represent useful non-invasive biomarkers for assessing recent PAH
uptake from all exposure routes [Ganzleben et al. 2017; Gunnier 2006; Srogi 2007].

Supplementing the pilot-scale human exposure measurements collected under the FRAP [EPA
and ATSDR 2024], this biomonitoring study examined urinary PAHs to assess the exposure
potential for individuals who performed activities on turf fields with recycled tire crumb rubber
infill. The same 7 urinary metabolites assessed in both studies are regularly monitored in the
general U.S. population [CDC 2020], and the four parent PAHs (anthracene, fluorene,
phenanthrene, pyrene) are among EPA's 16 Priority Pollutants [US EPA 2014]. This
supplemental study distinguishes itself in several ways. First, it featured a larger convenience
sample of study participants compared to the pilot study conducted under the FRAP; urine
samples from 161 participants with age ranging from 7-77 years were analyzed, compared to
urine samples from 14 participants in the pilot study with an age range of 11-21 years. This
larger sample size allowed for the examination of potential differences by select demographic
characteristics and behaviors. Additionally, this supplemental study also included a group of
participants whose activities took place on natural grass fields. Although the sample size of
natural grass participants was relatively small, this comparison group provided an important
examination of pre- and post-activity differences by field type.

In this study, pre- and post-activity urinary PAH concentration differences were not associated
with field type, regardless of urine adjustment method or statistical method applied. Consistent
with the pilot-scale study [EPA and CDC/ATSDR 2024], most participants demonstrated an
increase in specific gravity-adjusted PAH concentrations after performing field activities.
However, the increase occurred irrespective of field type, among both natural grass participants
as well as synthetic turf with recycled tire crumb rubber participants. Also consistent with the
pilot-scale study, our findings indicated fewer significant pre- and post-activity differences
when utilizing creatinine-adjusted results, underscoring the influence of urine-dilution
methods. These differences may potentially be attributed to how the degree of correlation of
specific gravity and creatinine with the true hydration status of an individual may vary due to
endogenous and exogenous factors [Kuiper 2021]. In the context of PAHs, for example, children
are generally a vulnerable group with potential for higher exposure to PAHs compared to adults
due in part to their less efficient detoxification system, lower body weight, and higher
inhalation rates [Oliveira et al. 2019]. Though age was not associated with post-activity PAH
concentrations, it was associated with some pre-activity concentrations. Additionally, potential

30


-------
sex-specific effects or differential responses to PAH exposure continue to be areas of
exploration [Farzan 2016; Xing 2023; Yang 2021], and differences in BMI or body composition
may contribute to differential PAH metabolism [Stallings 2018; Wang 2022]. However, in this
study, neither sex nor BMI were statistically associated with pre- and post-activity differences in
PAH concentrations in univariate or multivariate regression models.

In the absence of other measures of urinary dilution such as osmolality and urine flow rate
[Middleton 2016], the comprehensive approach taken in this present study facilitated
examination of other datasets, including NHANES 2007-2008 and 2015-2016. NHANES 2007-
2008 data, which collected both specific gravity and creatinine, also revealed large differences
between specific gravity- and creatinine-adjusted PAH concentrations. Our comparison of
creatinine-adjusted PAH concentrations available in both NHANES cycles indicated that urinary
PAH concentrations markedly decreased over time, except for 2-NAP. Differences in creatinine-
adjusted urinary 2-NAP were detected in pre- and post-activity samples from this biomonitoring
study as well as the previous pilot-scale study [EPA and CDC/ATSDR 2024]. In both the studies,
the creatinine adjusted 2-NAP concentration (geometric mean) was higher pre- and post-
activity when compared to the general US population based on available NHANES data. In our
biomonitoring study, this observation held for all age groups except for youth (participants
aged 10-12 years). Previous urinary biomarker investigations utilizing NHANES have also
indicated naphthalene, the parent PAH of 2-NAP with widespread presence in ambient and
indoor air, as the dominant PAH in the U.S. population [Li 2008]. Data from the pilot-study,
however, indicated low levels of naphthalene in tire crumb rubber infill, field air, field dust, field
wipe, and drag sled samples [U.S. EPA and CDC/ATSDR 2024].

Overall, measurable amounts of urinary hydroxylated metabolites of PAHs were found in users
of both synthetic turf fields and natural grass fields. However, finding a measurable amount of
urinary hydroxylated metabolites of PAHs does not indicate they cause an adverse health effect
[ATSDR PAH Clinical Assessment 2023]. Previous biomonitoring studies have demonstrated that
nearly 100% of the general U.S. population have detectable levels of urinary PAH metabolites
[Grainger 2006]. Exposure to PAHs in the general population occurs mostly through inhalation
of polluted air and cigarette smoke, and ingestion of food containing PAHs [ATSDR 1995].

Others have demonstrated that an exposure-free period of 24-48 hours is often required for
PAH biomarkers to reach pre-exposure baseline [Zheng 2012; Brzeznicki 1997; Chien 2010; Viau
1995]. More recently, data from Choi et al. 2023 demonstrated that the fractional urinary
excretion of urinary PAHs ranged from 0.07 % to 11.3% and that most were excreted within 24
hours after exposure, though the obtained fractional urinary excretion values only reflected
oral intake [Choi 2023]. Accordingly, this study excluded participants who were smokers,
excluded natural grass participants who had played on synthetic turf within the past 24 hours,
and accounted for the ingestion of grilled foods within the past 24 hours. Outdoor synthetic
turf fields were also co-located with natural grass fields to help account for potential PAHs in
ambient air. Nevertheless, this study could not fully control for potential exposures to
chemicals from other sources and environmental media that could occur off the field. As
described previously [EPA and CDC/ATSDR 2019], while there is concern about chemical
exposures resulting from the use of recycled tire in synthetic turf fields, it is important to
consider that some PAHs and other chemicals are also found in surface soil and may be present

31


-------
in othertypes of fields, including natural grass fields. For example, metals (including lead) and
PAHs (including benzo[a]pyrene) of potential concern at synthetic turf fields with tire crumb
rubber infill are also often found in surface soil present at natural grass playing fields [EPA and
CDC/ATSDR 2019],

5.1. Limitations and Recommendations

Like the pilot-scale human exposure measurement study conducted as part of the FRAP, this
current study's examination of participant activity on synthetic turf fields was limited in design
to assess exposure to recycled tire crumb rubber (infill alternatives were not included) and did
not investigate exposure to synthetic turf field materials or components such as synthetic grass
blades and backing material. Also consistent with the constraints of the research activities in
the FRAP, there was no way to determine the specific tire sources for tire crumb rubber at the
participating fields. While the facility and indoor or outdoor field environment was considered,
this study did not examine the potential of dust transfer or effects of water-runoff between the
co-located natural grass fields and synthetic turf fields. Future research activities may also
choose to expand the scope of exposure measurement studies to incorporate synthetic turf
fields that use alternative types of infill as another means of comparison further allowing
communities to make more informed choices.

Though some statistical models indicated a difference between pre- and post-activity PAH
concentrations, these differences were dependent on choices such as In-transformation, urine
dilution adjustment method, and model specification. In all cases, observed pre- and post-
activity differences were not explained by field type (exposure to synthetic turf). Observed
differences could be due to unmeasured variables, such as changes in hydration level through
perspiration. However, it is unknown whether a participant drank fluids between the two
specimen collections, nor how much fluid they lost due to intensity of activity. For the urine
collection, participants were directed to not touch the inside of the urine specimen container to
prevent or minimize chances of sample contamination. However, the study recruitment team
cannot confirm that all participants followed the specified procedures.

For future related studies, additional information obtained at the time of specimen collection
might help provide insights on factors affecting PAH concentrations. For example, asking about
fluid consumption during the activity (between pre- and post-specimen collections), and taking
pre- and post-body-weight measurements (to measure potential fluid loss or gain) could help
tease out factors driving pre- and post-activity concentration differences. As previous studies
have indicated the potential effect of vaporization and weathering on organic chemical level
concentrations [Marsili et al. 2014; EPA and CDC/ATSDR 2019], additional efforts could examine
or account for the role of fluctuations in weather or field temperatures over time. Moreover,
although information including the time recorded between samplings and general patterns of
activity were captured in this study, these data may not directly correspond to the level of
activity each participant exerted on the field; additional measures could be included to account
for behaviors specific to the day-of specimen collection.

6. Conclusions

Although this study's findings cannot be generalized to the universe of synthetic field users with
exposures to tire crumb rubber infill in the United States, this study provides valuable
information to better understand and identify the potential chemical exposures. Notably, pre-
and post-activity differences in urinary PAH concentrations were not associated with field type
(i.e., synthetic turf with recycled tire crumb rubber infill compared to natural grass). This was
consistent regardless of the urine dilution adjustment method applied or the statistical
regression technique employed. When examining pre- and post-activity urinary PAH
concentration differences overall, results varied by statistical method; methods that mitigated
the effect of extreme observations were more likely to yield results that were not statistically
significant, indicating that outliers could be driving some of the results. After exploring the role
of different variables associated with pre- and post-activity concentrations, the best predictor
of post-activity urinary PAH concentration was pre-activity concentration. Except for 2-NAP,
pre-activity PAH concentrations were lower than those in the general U.S. population using
2015-2016 NHANES comparison data. It is important to note that this report is not a risk
assessment. However, this study's findings supplement the pilot-scale human exposure
measurements collected under the FRAP and contribute to the overarching portfolio of
research activities needed to understand the potential for human exposure to chemicals found
in recycled tire crumb rubber used on synthetic turf fields.

PAH = Polycyclic Aromatic Hydrocarbon.

BMI categories (underweight, normal, overweight, and obese) corresponded to cut points at <18.5, <25, <30, and >=30, respectively, for adults 20 years and older. CDC growth
charts were used to calculate BMI for participants <20 years old with cut points defined at BMI percentages (0,5), [5,85), [85,95), and 95+. Because age was only collected for

60


-------
whole years and age-in-months is required to properly use growth charts, BMI calculations for participants under 20 years old were subject to misclassification due to rounding.
See SAS Program for CDC Growth Charts. See: https://www.cdc.gov/nccdphp/dnpao/growthcharts/resources/sas.htm.

Appendix B
Quality Assurance and Quality Control

89


-------
B.1 Quality Overview and Planning

Appendix B does not describe quality assurance/quality control (QA/QC) activities and results for the
biomonitoring portions of the exposure characterization pilot study. Appendix B describes only those
QA/QC documentation, procedures, and results for EPA-led activities. Biomonitoring QA/QC
procedures and results are described in Appendix A.

The U.S. Environmental Protection Agency (EPA) requires that all data collected for the
characterization of environmental processes and conditions are of the appropriate type and quality for
their intended use. This is accomplished through an EPA-wide quality system for environmental data.
Components of the EPA quality system can be found at http://www.epa.gov/quality/. EPA policy is
based on ANSI/ASQ E4-2004 (an American National Standard). This standard recommends a tiered
approach that includes the development and use of Quality Management Plans (QMPs). The
organizational units in EPA that generate and/or use environmental data are required to have EPA-
approved QMPs. Programmatic QMPs may also be written when program managers and their QA staff
decide a program is of sufficient complexity to benefit from a QMP.

A programmatic QMP was developed for the research conducted under the Federal Research Action
Plan on Recycled Tire Crumb Used on Playing Fields and Playgrounds, described here as the Tire
Crumb Research Study (TCRS). The TCRS QMP describes the program's organizational structure,
defines and assigns QA and QC responsibilities, and describes the processes and procedures used to
plan, implement and assess the effectiveness of the quality system. The TCRS QMP is supported by
project-specific QA project plans (QAPPs).

The TCRS QAPPs provide the technical details and associated QA/QC procedures for the research
activities that address TCRS objectives as described in the TCRS Research Protocol, "Collections
Related to Synthetic Turf Fields with Crumb Rubber Infill." Written sample collection and analysis
research-level standard operating procedures (SOPs) were also prepared to support the QAPPs, when
appropriate.

The following elements were critical for producing high-quality research results:

•	Research projects comply with Agency requirements and guidance for QAPPs, including the
use of systematic planning;

•	Technical system audits (TSAs) and data quality reviews, as described in the QMP or project-
specific QAPPs;

•	QA review of all products that include environmental data; and

•	Inclusion of a QA/QC section in the final study report.

This research was supported by a Program QA Manager (PQAM) who was independent of the technical
work and who assisted the QA staff in the implementation of the TCRS quality program and QMP
requirements. Requirements specified in the TCRS QMP and QAPPs were intended to ensure
consistency in the QA approach for all participating organizations.

91


-------
B.2 Quality Assurance Activities and Results
B.2.1 Quality Assurance Project Plans

As part of the QA processes implemented in this research study, QAPPs were prepared by research staff
for several components of the TCRS, including the Literature Review/Gaps Analysis and the tire crumb
rubber characterization, and the exposure characterization. QAPPs were reviewed and approved by the
respective research staff supervisors and QAMs. QAPPs (or QAPP addendums) prepared for the tire
crumb characterization portion of the study were described in the Part 1 Report (EPA/600/R-19/051).
One QAPP and two QAPP addendums were prepared for the TCRS exposure characterization pilot
study (Table B-l) and related activity assessment research.

B.2.2 Standard Operating Procedures

Research-level SOPs were developed for all sample collection, data collection and sample analysis
activities. Prior to undertaking the activities covered by a SOP, the SOP was reviewed and approved by
the respective research staff supervisors and QAMs. Research-level SOPs developed or applied in the
exposure characterization pilot study are provided in Appendix C.

B.2.3 Technical Systems Audits

The EPA Office of Research and Development (ORD) quality program requires at least one audit be
conducted per project, at a minimum. However, due to the high visibility and multi-component nature of
the TCRS, a robust quality review process (including technical system audits and data quality reviews)
was implemented to identify and correct issues immediately. Several audits for tire crumb sample
collection and sample analysis activities were previously described in the Part 1 Report (U.S. EPA &
CDC/ATSDR, 2019). Additional technical system audits (TSAs) were conducted on exposure pilot
study field sampling and for the publicly-available videography data compilation. The purpose of each
audit was to ensure that the research tasks prescribed within the QAPPs or SOPs were verified and
documented. These audits are summarized in Table B-2. No significant findings were identified
during the audits, and minor findings that were identified did not directly affect the integrity or
quality of the data.

B.2.4 Deviations from the QAPPs or SOPs

There were no significant deviations from the QAPP addendums listed in Table B-l. Deviations from
SOPs identified during field or laboratory activities were documented and confirmed, if applicable,
during field or laboratory audits. All SOPs unique to this project that deviated from the original
procedure were amended and, if needed, reviewed by the QAM and approved by the analyst's
supervisor. Minor changes such as mislabeled sampling containers, contaminated sampling tools or
issues identified in the field related to specific samples or information collection were documented on

Onsite TSA was conducted at the NERL laboratory, RTP office to assess QA/QC
procedures specified in the SOP for Collecting and Using Extant Publicly Available
Video. Coding of the extant videography data had not been performed prior or
during the audit, therefore, only those activities involving collection and handling
of videography files could be assessed. Findings included lack of research
notebooks to document daily activities. Corrective action was issued to the group
coding the collected data and to the task lead.

B.2.5 Data Quality Reviews

Reviews of data quality were performed at several stages throughout the course of the research study
(Table B-3). Data produced through field sample collection, data collection and sample analysis
received data quality reviews by QAMs and/or secondary technical expert reviewers. Reviews were
performed after data were produced and before they were submitted for data processing or included in
data analysis.

Much of the analytical chemistry measurement data for the exposure characterization pilot study was
compiled, standardized and processed by data managers to prepare data analysis files. Data quality
reviews were performed to verify that the data in the data analysis files were correct and complete and
that all processing calculations were performed correctly.

Using the data analysis files, data were organized to prepare outputs for reporting, such as tables and
figures. Statistical summaries of the data were prepared and in some cases, statistical testing was
performed. Data quality reviews were performed to ensure that the data analysis outputs were complete
and correct and that data calculations and analyses were performed correctly.

Finally, multiple data quality reviews were performed to verify that the outputs from the data analyses
were correctly and completely compiled in report tables and figures. This set of data quality reviews is
depicted in the Table B-3, but does not quantify the number of reviews completed for data compilation
and analysis.

B.3 Quality Control Overview

Numerous quality control activities and analyses were performed over the course of the study and
included, but were not limited to the following:

•	Sample collection media and sample containers were pre-cleaned or purchased as certifiably
clean, when appropriate;

•	Whenever possible, media were evaluated prior to field deployment to ensure minimal
background or interferences, and blank media were analyzed to assess potential background
contamination;

•	Chain of custody procedures were implemented for all samples;

•	Field quality control samples, consisting of blank, spike, and duplicate samples, were taken
when applicable; location-specific field blanks were taken to and handled in the field in the
same manner as samples, including opening and closing of containers, where appropriate;

•	Laboratory quality control samples were applied, as appropriate, for each analysis method and
included one or more of the following: procedure or method blanks and spikes, matrix blanks
and spikes where feasible, and replicate sample analysis;

•	Reference standards were obtained from reputable and traceable sources, where available;

•	Solvents used for device cleaning, media preparation, or sample extraction were HPLC-grade or
better in purity;

•	Appropriate methods were used to determine analytical detection or quantifiable limits and to
quantify target chemical amounts in samples;

•	Blank and recovery correction were applied, as appropriate;

•	Research notebooks were maintained.

Key quality control measures and their results are reported in this Appendix, including:

•	Completeness: a measure of the amount of verified data obtained from a measurement system
compared to the amount of data that was expected to be obtained under normal conditions.

•	Quantification Limits: the lowest concentration or amount of analyte that can be measured in an
analytical method to a known and acceptable degree of confidence and precision. This is
determined in a manner that is appropriate and applicable for each type of measurement.

•	Background: the amount of analyte or signal present that was not associated with the sample
and can interfere with or inflate measurement results. Background is assessed by using unspiked
field and/or laboratory media and analyses.

•	Precision: a measure of mutual agreement among individual measurements of the same
property, usually under prescribed similar conditions. Precision is best expressed in terms of the
standard deviation.

•	Accuracy: the degree of agreement of measurements (or an average of measurements) with an
accepted reference or true value. Accuracy is a measure of the bias or systematic error in a
system and was assessed by measuring recovery of target analytes through laboratory analysis
and where applicable, through combined field and laboratory conditions and procedures.

Each of these general quality criteria and the process by which they were addressed were not universal
throughout the study. Each analyst's task and characterization process could differ substantially;
therefore, it was impossible to have a single standard operating procedure or consistent approach for
addressing or validating all methods used in tire crumb rubber characterization and exposure

96


-------
measurement analysis. This Appendix describes how each method addressed the general quality control
measures described above.

Each analytical method had its own set of quality control measures appropriate for that method. In
addition to the assessments listed above, the SOPs for the sample collection and sample analysis
methods described quality control elements that were implemented for each method. Not all quality
control procedures and results are reported here. For example, calibration procedures and acceptance
criteria, mass spectrometer tuning check procedures, and other quality-related activities related to
quantitative analysis were described in the quantitative analysis SOPs. Quality control procedures for
field sample collection and analysis were also described in their respective SOPs.

£3.3.7 Exposure Characterization Pilot Study

The exposure characterization pilot study included several types of quality control samples for each field
and lab medium that was sampled (Tables B-4 and B-5, respectively). Field blanks were used to assess
potential contamination or background. Where applicable, the field blanks (e.g., dermal wipes and field
wipes) were handled at the field site in the same way the samples were handled to account for any
potential contamination during handling (e.g., chemical transfer from gloves). Spiked field controls were
deployed where possible to assess overall analyte recovery through the field condition, transport,
storage, and analysis activities. Duplicate samples were collected when possible to assess overall
measurement precision. Laboratory blanks and laboratory spiked controls were prepared to assess
background and recovery for media not deployed to the field sites.

Overall project-level DQI are listed in Table B-6. Because there are no standard methods for sample
collection and analysis procedures for measuring environmental and personal exposures at synthetic turf
fields, the DQI target values developed for exposure characterization were considered to be objectives
and were assessed as the work proceeded and following work completion. Additional data quality
indicators were described, where applicable, in the technical SOPs for each experimental or analytical
method.

B.4 Exposure Characterization Pilot Study Quality Control Results

Exposure characterization pilot study quality control information, measurements, and results are
reported in the following subsections for:

•	Measurement of total suspended particulate in field air samples (Section B.4.1),

•	Measurement of metals by ICP/MS in field air, field dust, field wipe, and dermal wipe samples
(Section B.4.2),

•	Measurement of VOCs by TD/GC/TOFMS in field air samples (Section B.4.3),

•	Measurement of SVOCs by GC/MS/MS in field air, field dust, field wipe, drag sled, and dermal
wipe samples (Section B.4.4),

•	Attempted measurement of SVOCs by LC/MS in field air, field dust, field wipe, drag sled, and
dermal wipe samples (Section B.4.5),

•	Field user questionnaires (Section B.4.6), and,

•	Video activity data analysis (Section B.4.7).

B.4.1 Total Suspended Particulate in Field Air QC Samples

Total suspended particulate was measured in field air during four sample collection events. All
scheduled samples were successfully collected and analyzed. Five field blanks carried to the field sites
and returned with the samples had average weight increases on the filters of 5.8 ± 4.4 |ag/fiIter. Five lab
blanks that remained in the laboratory had average weight increases on the filters of 1.6 ± 3.4 |ig/filter.
The average field blank result was subtracted from the total suspended particulate measurement prior to
calculating concentrations in air. The average percent relative standard deviation for four duplicate
sample collection and analysis measurements was 11 ± 5.0%.

Blanks - Table B-8 reports average concentrations of metals across field and laboratory blanks for field
and dermal wipes and field air filters. Relatively high background levels were observed in the wipe
materials for aluminum, iron, magnesium and zinc. These were also elements with relatively high
measurement results in the tire crumb rubber samples. Metals concentrations were adjusted for each
sample by subtracting the field blank result obtained for each field site from the analysis result for each
metal in samples collected at that field site.

Recovery - Table B-9 reports recovery results for metal analytes from the method spike solution and
field and dermal wipe spiked controls across field and laboratory sampling. Average recoveries from the
spiked controls ranged from 83% to 120%.

No standard synthetic turf field dust sample is available, and there are no methods for spiking an
equivalent dust with metals. The National Institute of Standards and Technology (NIST) standard
reference material (SRM) 1648a (urban particulate matter) was used to prepare field and laboratory
controls. Recovery of metals from this material were uneven, and not all metals had certified values.
Results are shown in Table B-10. Recoveries for cadmium, cobalt, lead and zinc ranged from 74% to
110%. However, the average recovery for chromium was only 20%. It is not known how well this urban
particulate matter SRM represents dust collected from synthetic turf fields. No recovery adjustments
were performed for the exposure characterization pilot study samples.

Precision -Duplicate samples were collected for field air and for field wipe samples. Measurement
precision results for metals in these duplicate samples are reported in Table B-l 1. Average % relative
standard deviation (%RSD) values for metals in field air duplicates ranged from 3.7% to 98%. The
average %RSDs for cobalt, lead, and zinc in field air duplicates were 6%, 11%, and 39%, respectively;
the average %RSD for chromium was 56%. Average %RSD values for metals in field wipes ranged
from 7% to 24% for all metals except cobalt, which had an average %RSD of 53%. Duplicate
measurement results for field wipes may include components of both measurement precision as well as
spatial heterogeneity in loading levels across sampled surfaces.

DOI- Based on the quality control measurement results, DQI objectives were met for lead in all media.
All metals met recovery objectives in the field air and the field and dermal wipe media; however,
recoveries were uneven in the dust surrogate (NIST SRM 1648a) media. Precision was uneven in the
field air media, but all metals except cobalt met the precision objective in the wipe media.

B.4.3 VOCs in Field Air QC Samples

Completeness - All (100%) of the scheduled exposure characterization pilot study active fence line
monitor (FLM) field air samples were successfully collected and analyzed. None of the sample
measurement results from the Radiello passive field air samples or personal air samples were reported in
Volume 1 of this report due to inconsistent sample collection rates determined between laboratory and
field trials and because of unacceptably low recoveries for benzothiazole and methyl isobutyl ketone.
However, results for the Radiello quality control samples are reported in this Appendix.

Quantification Limits - Table B-12 reports the method detection limits for VOC analytes in FLM field
air samples.

Blanks - Table B-19 reports average concentrations of SVOC analytes in air filter field and laboratory
blanks. High background levels were observed for diisobutyl phthalate, with other analytes much lower.

Field dust quality control samples were prepared using solvent-cleaned and heat-baked diatomaceous
earth. Table B-20 reports average concentrations of SVOC analytes in dust field and laboratory blanks.
Cyclohexylisothiocyanate was found at 50 ng/sample, with other analytes much lower.

Field air and field dust sample concentrations were adjusted by subtracting the field blank result
obtained for each field site from the analysis result for each SVOC in samples collected at that field site.

Table B-21 reports average concentrations of SVOC analytes in field wipe field and laboratory blanks.
Bis(2-ethylhexyl) phthalate had the highest measured background levels (79 ng/wipe). Table B-22
reports average concentrations of SVOC analytes in drag sled field and laboratory blanks. Bis(2-
ethylhexyl) phthalate had the highest measured background levels (930 ng/wipe) followed by
benzothiazole (216 ng/wipe).

Table B-23 reports average concentrations of SVOC analytes in dermal wipe field and laboratory
blanks. Diisobutyl phthalate had the highest measured background levels (2100 ng/wipe) followed by
benzyl butyl phthalate (151 ng/wipe). The field wipe and dermal wipe field blank wipe material was
handled in the field using gloved hands to mimic handling for the samples. Sample concentrations were
adjusted by subtracting the field blank result obtained for each field site from the analysis result for each
SVOC in samples collected at that field site.

Recovery - Table B-24 reports recovery results for SVOC analytes measured in air filter spiked field
controls and spiked laboratory controls. Average recoveries ranged from 0% to 232% for controls not
corrected for blank levels. Most SVOCs had average spiked field control recoveries in a range from 70%
to 120%. Aniline had an average recovery of 18% in spiked field controls, while n-butylbenzene and
napthalene had recoveries of 54% each. These were the three most volatile analytes and there may have
been losses during the extraction solvent volume reduction step. Diisobutyl phthalate and bis(2-
ethylhexyl) adipate had recoveries of 232% and 190%, respectively, in spiked field controls. The
diisobutyl phthalate recovery was inflated by the relatively high background levels (reported in Table B-
23).

recovery of 17% in the spiked field controls. The reason for the relatively low recoveries is not clear.
Uniform spiking of dust surrogate material is difficult, and some portion of the spiking solution may not
have been applied directly to the material. It is possible that recoveries from the diatomaceous earth are
not complete using the solvent and extraction method used. It is also not clear whether the surrogate
material provides a quality control measure that can accurately represent recoveries obtained from actual
field dust.

Table B-26 reports recovery results for SVOC analytes in field wipe spiked field controls and spiked
laboratory controls. Average recovery levels above 150% were measured for 2,6-di-tert-butyl-p-cresol,
4-tert-octylphenol, 2-hydroxybenzothiazole, benzyl butyl phthalate, and bis(2,2,6,6-tetramethyl-
4piperidyl) sebacate in spiked field controls. Aniline had an average recovery level of 32% in spiked
field controls, likely due to losses during the solvent extraction volume reduction step. Average
recoveries ranged from 62% to 144% for the remainder of the SVOC analytes.

Precision - Table B-29 shows precision results for SVOC analytes in field air, field wipe and drag sled
duplicate samples when both of the measurement results in a pair were > 0. Average %RSD values for
SVOCs in field air duplicates ranged from 1% to 101%. In many cases, the higher %RSDs were the
result of measurements near or below the minimum quantifiable limits. Average %RSD values for
SVOCs in field wipe duplicates ranged from 2% to 119%, with results for most analytes < 50 %RSD.
Field wipe duplicates may reflect spatial heterogeneity in analytes on the field surface in addition to
measurement precision. In many cases, the higher %RSDs were the result of measurements near or
below the minimum quantifiable limits. Average %RSD values for SVOCs in drag sled duplicates
ranged from 10% to 71%, with results for most analytes < 35%. Drag sled duplicates may reflect spatial
heterogeneity in analytes on the field surface in addition to measurement precision. In many cases, the
higher %RSDs were the result of measurements near or below the minimum quantifiable limits.

DOI - Recovery and precision DQI objective values were not met for a portion of the SVOC analytes
across the exposure characterization pilot study field air, field dust, field wipe, drag sled and dermal
wipe samples. For each sample type, the quality control results were examined as a whole, and decisions
were made to not report measurement results for some chemicals in Volume 1 of this report. Exclusion
decisions were primarily made because of high background, high recovery or very low recovery.
Analytes that were retained in the report may have not met all DQI objectives in all media.

-------
Analyte measurement results that were not reported in Volume 1 of this report are shown below for each
sample type:

•	Field air samples - aniline, napthalene, n-butlybenzene, 2-bromomethylnaphthalene, diisobutyl
phthalate, bis(2-ethylhexyl) adipate, and bis(2,2,6,6-tetramethyl-4piperidyl) sebacate
measurement results were not reported.

•	Field dust samples - aniline, napthalene, n-butylbenzene, cyclohexylisothiocyanate, 2-
bromomethylnaphthalene, bis(2-ethylhexyl) adipate, and bis(2,2,6,6-tetramethyl-4piperidyl)
sebacate measurement results were not reported.

•	Field wipe samples - aniline, n-butylbenzene, diethyl phthalate, n-hexadecane, 2-
bromomethylnaphthalene, 2-hydroxybenzothiazole, diisobutyl phthalate, dibutyl phthalate,
benzyl butyl were not reported.

•	Field drag sled samples - aniline, n-butylbenzene, cyclohexylisothiocyanate, 2-
bromomethylnaphthalene, bis(2-ethylhexyl) phthalate, and bis(2,2,6,6-tetramethyl-4piperidyl)
sebacate measurement results were not reported.

•	Dermal wipe samples - cyclohexylisothiocyanate, dimethyl phthalate, diethyl phthalate, 2-
bromomethylnaphthalene, 2-hydroxybenzothiazole, anthracene, diisobutyl phthalate, dibutyl
phthalate, and bis(2,2,6,6-tetramethyl-4piperidyl) sebacate were not reported.

Overall, the methods for SVOC collection and analysis by GC/MS/MS performed adequately, but not
perfectly, for most target analytes. It is likely that better performance in field air sampling would be
obtained through the use of higher flow rates or collection volumes. For this study, it was decided that
portability and battery operation were necessary due to the nation-wide scope of the potential sampling
territory. It was also not certain how much time would be available to set up and take down equipment at
the fields, and whether suitable power supplies would be available. Relatively small amounts of some
analytes were captured with the field wipes and dermal wipes, with some degradation of quality
performance at very low concentrations. The much larger surface area sampled by the drag sled helped
alleviate some of the problems with small analyte amounts for that method. The field dust is a unique
material that may be hard to replicate for preparing suitable quality control samples. The time and
difficulty in collecting dust samples also impacts the ability to collect duplicate samples at fields.

B.4.5 Attempted Measurement ofSVOCs by LC/MS in Field Air, Field Dust, Field Wipe,
Field Drag Sled and Dermal Wipe QC Samples

During the tire crumb rubber sample analyses, tire crumb rubber was extracted using an acetone:hexane
(1:1) solvent mixture for analysis of target SVOC analytes by GC/MS/MS. Extraction was accomplished
using a simple vortex mixing procedure and, due to the relatively high concentrations of most target
analytes, no solvent volume reduction step was required. For tire crumb rubber extracts, a solvent
exchange into methanol was successfully performed to allow analysis of the following analytes in crumb
rubber by LC/MS:

•	2-Mercaptobenzothiazole,

•	2-Hydroxybenzothiazole,

•	Cyclohexylamine,

•	Dicyclohexylamine,

•	N-Cyclohexyl-N-methylcyclohexanamine,

•	Diisononylphthalate, and,

•	Diisodecylphthalate.

129


-------
As part of the exposure characterization pilot study, there was interest in learning whether LC/MS
analysis methods could successfully be applied for analysis of SVOCs using the exposure study
environmental and personal samples that were collected and analyzed by GC/MS/MS. All of the air,
wipe, and dust sample media were extracted for GC/MS/MS analysis using an acetone:hexane (1:1)
solvent mixture. Other than for field dust, a solvent volume reduction step was performed to concentrate
the analytes which were present at relatively low levels. Following the GC/MS/MS analyses, the sample
extracts were solvent exchanged into methanol to attempt LC/MS analyses.

The LC/MS quality control results for duplicate samples, field and laboratory blanks, field and
laboratory spiked controls, matrix spike samples, recovery spike samples, and calibration check analyses
were reviewed. Overall, the methods did not meet data quality indicator objectives for any of the target
analytes. Recoveries of spiked analytes in lab and field controls and in matrix spike samples were below
30% in all test samples, and often below 10%. The duplicate samples, when target analytes were
detected, often showed poor reproducibility. Therefore, no exposure characterization pilot study LC/MS
measurement results are included in this report.

Due to the multiple steps needed for extraction, solvent reduction, and solvent exchange to generate
extracts for GC/MS/MS and LC/MS analyses, there are several places where analyte losses could occur
due to volatilization or adsorption to materials. This problem becomes more acute due to the relatively
low amounts of target analytes collected in most samples. In the future, it may be necessary to collect
environmental and personal samples expressly for LC/MS analysis and to develop and test suitable
extraction procedures for those samples.

B.4.6 Field User Questionnaire Quality Control

Field user activity questionnaires were administered to exposure pilot research study participants by
trained interviewers. Interviewers filled out the questionnaire forms during the oral interview.
Questionnaires were reviewed for completeness at the field site. All questionnaires received 100%
duplicate keyed entry; any discrepancies between the two entries were resolved and the data entry was
finalized. Following data entry, the questionnaire results received a data quality review by an
independent staff member. All result compilations for reporting were verified through report table
reviews.

B.4.7 Video Activity Data Analysis Quality Control

B.4.7.1 Publicly-Available Video Data Quality Control

Quality control measures for the publicly available video data acquisition and analysis are described in
Volume 1, Section 3.5.1.

B.4.7.2 Participant Video Quality Control

Quality control measures for the exposure pilot study participant video data acquisition and analysis are
described in Volume 1, Section 3.5.2.

7.1	General Data and Information Collection Information

Information regarding field conditions, field environment, and activities will be collected as part of the
exposure characterization pilot field study conducted at each participating fields. Information will be


-------
SOP: D-SED-IEMB-030-SOP-01
Date: August 21, 2017
Page: 5 of 15

collected on structured record forms, but will allow for open-ended observations to be recorded. Data
and information collection procedures are described below for each of the six categories of
information.

7.2 Meteorological Conditions Data Collection

7.2.1	Select meteorological information will be measured and recorded at three time points around the
monitored participant activities each day at each field. The three time points include the approximate
start of monitored participant activities, the approximate middle time point of the monitored participant
activity, and at the approximate end time of participant activities. If field staff must prioritize their
time, the priority should be in deploying and collecting participant samples. Meteorological
information can be measured and recorded shortly before or after working with participants, if
necessary. Meteorological measurements should be performed on the synthetic turf field and as close
to the participant activities as is practical and safe.

7.2.2	At each time point, use the Kestrel 5500 handheld meteorological measurement device.

7.2.2.1	Record the time of day the observations were begun for each time period.

7.2.2.2	Power on the device by pressing and holding the 'on' button.

7.2.2.3. Allow the device to equilibrate to current conditions at 1 m above the field surface for five
minutes.

7.2.2.4	Press the 'mode' button to obtain the temperature reading in °C and record the temperature
measurement at a 1-m height above the field. Note: the Kestrel 5500 will be shaded during this
measurement period to avoid direct sunlight causing and incorrect reading of ambient air temperature.

7.2.2.5	Power the device off by holding the 'on' button. Determine the prevalent wind direction at a 1-
m height using a portable vane or streamer. Aim the wind meter rotor at the prevalent wind direction at
a 1-m height above the field. Turn the device on, and after 60 seconds press the 'mode' button until the
average wind speed is displayed. Record the average 60-second wind speed. Press the 'mode' button
again to get the peak wind speed during the 60-second period and record the peak wind speed. Record
wind speeds in units of km/h.

7.2.2.6	Use a compass to determine the predominant direction the wind is coming from. Record the
direction the wind is coming from in compass degrees from magnetic north.

7.2.2.7	Place the device flat on the surface of the field in an exposed location for five minutes to
measure the field surface temperature. After five minutes, and while the device is still on the field,
cycle through the 'mode' button to obtain the temperature reading. Record the field surface
temperature in °C.

7.2.2.8	By observation, record whether the field surface is wet from dew (yes/no), whether the field is
wet from rain or other source of water besides dew (yes/no), and the current general sky conditions
(sunny, partly cloudy, cloudy, drizzle, rain).

7.2.9 7.2.9For each day of meteorological data collection, record the field ID number, date, and
whether the field is an indoor or outdoor field.

7.3 General Field Information/Observations


-------
SOP: D-SED-IEMB-030-SOP-01
Date: August 21, 2017
Page: 6 of 15

7.3.1	Use the General Field Information/Observations collection form to record information about the
field and surrounding environment that may be useful for understanding and interpreting the exposure
characterization pilot study measurement results. This is an open-ended observational record form that
should be completed on each day of monitored participant activities.

7.3.2	The form lists several examples of types of observations of interest as examples. However, the
field staff should record information for any observations they believe should be communicated.

7.3.3	The form can be partially completed prior to or after monitored participant activities if the
observations are about something that will not change or vary during the monitored activities.

However, observed conditions potentially affecting or relevant to measurements performed should be
recorded during the monitored participant activities. For example, the level of traffic on adjacent roads
or parking areas could be relevant to the air sample collection measures.

7.3.4	Depending upon the type of observation, it may be necessary to also include the time or time
interval that you observed the condition or activity. Such examples might include a car, truck or bus
idling in the parking lot or road; precipitation conditions or construction activities.

7.3.5	For each day of information collection, record the field ID number and date.

7.4	General Activity Information

7.4.1	Use the General Activity Information collection form to record information about the overall
activities (types and estimated numbers of people) that occur on the participant activity field and
surrounding fields during the monitored participant activity. A new form should be used for each day
of monitored participant activities at each field.

7.4.2	Information should be collected at three time points including the approximate start of monitored
participant activities, the approximate middle time point of the monitored participant activity, and at
the approximate end time of participant activities.

7.4.3	The structured form lists specific types of information to collect.

7.4.4	For each day of information collection, record the field ID number and date.

7.5	Participant Information

7.5.1	Use the Participant Information collection form to record information about each participant
during their monitored activity at the synthetic turf field. A new form should be used for each
participant. The form should be completed for all participants, including those that are participating in
the video recording portion of the study. The research team plans to have participants wear pinnies
with unique participant identifiers (1 - 8) to differentiate the participants. A maximum of four
participants per day is expected.

7.5.2	Information about participant activities should be at the start, at approximately 30-minute
intervals, and at the end of their monitored activity. Information about participant clothing and
equipment should be collected once during the monitored activity; if the clothing or equipment
changes then that should be recorded as well.

7.5.3	The structured form lists specific types of information to collect.

7.5.4	For each participant information collection record, record the field ID number, date, and
participant number.

7.6	Field Sample Location Record

7.6.1	Use the Field Sample Location Record form to record the sample collection location for each
type of sample collected. The form should not be used for quality control samples. Only one form
should be completed for each field even if samples are collected on more than one day.

7.6.2	A single letter code should be used for type of sample:

Field SVOC wipe locations	S

Field metals wipe locations	M

Field SVOC drag sled locations	D

Air sample station locations	A

7.6.3	On the field diagram, write the sample type code at each place on the field where samples are
collected. For the upwind off-field air sample station, place the code in the correct direction for the
field orientation, and write down an estimate of the distance (in meters) from the center point of the
field.

7.6.4	In the upper right corner box, draw a directional arrow representing magnetic north using a
compass.

7.6.5	Record the field ID number and sample collection date (or the first day of sample collection if it
is performed over more than one day; for example, if air samples are collected on one day and wipe
samples on another).

7.7	Field Environment Record Form

7.7.1	Use the Field Environment Record form to sketch and label the built and natural structures
within approximately 100 meters of the field in each direction. The form needs to be completed only
one time, and can be completed during times that don't involve participant activities.

7.7.2	Of interest are parking areas, other fields, buffers, buildings, roads and other natural and built
features.

7.7.3	Note the approximate off-field sampling station location.

7.7.4	In the upper right corner box, draw a directional arrow representing magnetic north using a
compass.

7.7.5	Record the field ID number and sample collection date (or the first day of sample collection if it
is performed over more than one day; for example, if air samples are collected on one day and wipe
samples on another).

1.0 Scope and Application

This method applies to the collection of semi-volatile organic compounds (SVOCs) from
ambient air at activity fields that utilize crumb rubber and/or artificial turf. Samples will be
analyzed for a suite of SVOCs.

2.0	Summary of Method

Portable, battery operated, air sampling pumps equipped with polyurethane foam (PUF)
cartridges will be used to absorb gas-phase and particle-phase SVOCs from ambient air.

2.1	Definitions

COC - chain-of-custody

Field Blank - sampling media that travels with and is handled like regular sampling media

with the exception that it is never opened and exposed to the environment for sampling

Field Control - sampling media that has been spiked with a known concentration of select

compounds. This media also travels with and is handled like regular sampling media with

the exception that it is never opened and exposed to the environment for sampling

PUF - polyurethane foam

QAPP - quality assurance project plan

SOP - standard operating procedure

SVOCs - semi-volatile organic compounds

VOC - volatile organic compounds

OD - outer diameter

ID - inner diameter

lpm - liters per minute

3.0 Prerequisites Prior to Field Sampling

JTI will test sampling pumps. Use the procedure outlined in Section 5.2 to verify the
sampler can achieve and maintain a flow rate of 20 lpm. EPA has provided a number
of working pumps including spares. If a pump is not working, switch out the pump with
one that can.

JTI will replace the Tygon tubing (V2 inch OD, 5/16 inch ID, 3/16 inch wall) if visually
dirty, sticky, or occluded in order to protect the pump only. It does not need to be
replaced after each field study. EPA provided new, clean tubing at the start of the study


-------
Crumb Rubber SVOC Sampling
D-EMMD-SSAB-012-SOP-01

and it should last for the duration.

JTI will charge batteries. EPA has supplied a working 4-Bank Battery Charger (Battery
Tender P/N 022-0148-DL-WH). After connecting the charger to power and connecting
the batteries to the charger using the attached cords, charging will be automatic and
lights will turn solid green when battery charging is complete. More charging
information is available in the user's manual (Appendix II).

JTI will test the flow meter. EPA has supplied a working BIOS DryCal DC- Lite (Model

DCL-H Rev. 1.08) and JTI should only need to charge the unit using the power cord

supplied. If needed, a manual including operating, charging, maintenance, calibration,

and leak check procedures is available (Appendix III).

EPA will clean and prepare PUF cartridges, including blanks.

EPA will spike field control PUF cartridges.

EPA will print and label resealable bags containing sample media. Section 5.4 covers
the naming convention for the samples.

JTI will pack all field supplies listed in Section 3.1. Most equipment loaned by the EPA
has transportation enclosures. All equipment should be packed so as to avoid damage.

3.2 Training Requirements

All training required is provided by the US EPA. Sample collection will be conducted by
qualified scientific staff trained in the use of the specific field monitoring equipment.
Training will include a demonstration and hands-on training by qualified persons with air
sampling expertise. At a minimum, all SOPs and operating instructions will be reviewed,
understood, and followed exactly by the field staff. Training records will be maintained by
the exposure study project lead (Kent Thomas).

4.0 Cautionary Notes or Special Considerations

The sampling systems are powered by sealed lead acid batteries (gel cell). The battery and
pump system should be protected from excessive heat or cold (<50 °F, >104 °F). Pumps
and batteries are shielded from direct exposure by means of an outer protective enclosure
(see Figure 1). Precautions must be taken against shorting across the battery terminals or
reversing polarity of the power leads. Shorting of the battery may cause a rapid discharge
that will generate excessive heat and may result in a fire or severe burns. Reversing the
polarity (attaching positive to negative) may damage the pump or battery. Red (+) wires
should be attached to the red (+) battery terminal and black (-) wires should be attached to
the black (-) terminal.

Sampling may take place outside and personnel should be equipped to shield the samples
from possible weather events. Plastic trash bags or a tarp or other plastic bin can be used to


-------
Crumb Rubber SVOC Sampling
D-EMMD-SSAB-012-SOP-01
Page 6 of22
8/21/2017

cover the pumps/batteries. If sampling is stopped, the entire apparatus may be covered,
simply stop the pump and put the cap back onto the PUF sampler.

Sampling stands should be set-up so that they are provided protection from tampering.
Sampling stands must also be placed and secured such that no harm will come to children
or others playing in the vicinity of the equipment. Protective enclosures and plastic fencing
are provided and should be used to insure safety.

5.0	Procedures

The following procedures are listed below for Section 5.0.

1.	Pump and Sampling Set-up

2.	Pre- and Post-Sampling Flow Rate Measurement

3.	Sample Collection

4.	Labeling the Samples

5.	Pump/Equipment Take Down

6.	Return Filter Samples to the EPA Laboratory

NOTE: Set up the pump system at the correct location in advance of the anticipated on-field
activity so all sampling stations will be ready prior the beginning of the monitored on-field
activity.

5.1	Pump and Sampling Set-up

5.1.1	Transport the sampling setup and flow measurement equipment to the field location.
This will include protective enclosures, sampling pumps, batteries, power cords,
sampling stands, 3-pronged clasps, vacuum tubing, small screwdriver, and
measuring tape to the field location along with the data collection sheets, PUF
cartridge flow adapter, flow meter, pen, and any materials needed to secure the
monitoring site.

5.1.2	Three sampling sites will be identified for each field location and positioning of the
SVOC samplers is defined in the project Quality Assurance Project Plan (QAPP).
Two sites will be located next to or as close as possible to the activity field. One
site will be located off of the field, in an upwind position if possible. One sampler
will be located at each site and an additional sampler will be positioned at one of the
on-field locations to collect a duplicate sample. The project QAPP provides
guidance for drawing a map of the field to document the position of samplers. (See
D-SED-IEMB-030-SOP-01 Collection of Field and Activity Metadata During
Exposure Characterization Study Field Sampling for details.)

5.1.3	Figure 1 shows the sampler configuration and the major components are identified.
Use this diagram to setup each sampling location. Note that only part of the URG-

5.1.3.1	Open the metal protective case and set it on the ground.

5.1.3.2	Setup the sampling stand by inserting one end of the sampling stand into the
holder on the metal protective enclosure and attaching the 3-prong clasp to the
other end of the sampling stand.

5.1.3.3	Adjust the placement of the clamp on the ring stand until the measured
distance between the ground and the clamp is approximately 1 meter.

5.1.3.4	Open the pump, remove the tubing tucked inside the lid, and connect one end
to the hose barb found on the right rear of the pump unit. The attached hose
should be snug and not easily removed without use of applied force. Set the
pump into the protective enclosure on its side so that the hose is positioned
straight up.

5.1.3.5	The vacuum tubing will connect to the PUF cartridge once installed. Fornow,
loop the tubing up and over into the clasp. The upper loop of tubing will
ensure the tubing will not kink once the sampler is attached. (Note: If the
tithing kinks, secure the tubing with a zip tie (not tape) to the sampling stand
to maintain the upper loop.)

5.1.3.6 Place the battery into the lid of the protective enclosure. Attach the battery
power adapter to the pump unit by inserting the adapter into the 12V input
jack on the right rear of the pump unit near the hose barb. Attach the battery
adapter leads to the appropriate terminals of the battery. Attach the red lead to
the positive (+) red terminal and the black lead to the negative (-) black
terminal. Make sure good contact is made.

Pre- and Post-Sampling Flow Rate Measurement

Note: Flow rate measurement will take place before and after field
sample collection.

5.2.1	A "dummy" PUF cartridge and tubing (collectively referred to as the SVOC flow
adapter) will be sent along in a bag marked "flow adapters for SVOC sampling."

5.2.2	Remove the SVOC flow adapter and remove the orange/red plug from the end of the
"dummy" PUF cartridge. Inset this end into the vacuum tubing connected to the
sample pump.

5.2.3	The other end of the "dummy" PUF cartridge will be connect to a piece of tubing.
Connect this tubing to the bottom barb (outlet) on the BIOS flowmeter.

5.2.4	Turn on the pump by opening the pump lid and sliding the on/off switch located on
the pump deck to the "on" position (up). Allow the pump to run for 3-5 minutes to
warm-up and stabilize.

Note: The pump flow rate should be close to 20 1pm because the flow
rate was adjusted to this point using the flow adjustment screw
in the laboratory prior to field deployment. This will minimize
the amount of time required to fine adjust the pump flow after
the PUF sampler is attached.

5.2.5	After the stabilization period, press the "on" button of the BIOS unit.

5.2.6	Press and hold the "Read" button for approximately 3 seconds. This will activate the
unit to make continuous measurements and automatically average 3 replicate
readings.

5.2.7	Observe the flow rate values being displayed.


-------
Crumb Rubber SVOC Sampling
D-EMMD-SSAB-012-SOP-01
Page 9 of 22
8/21/2017

5.2.8	If needed, adjust the flow rate to 20.0 ±1.0 1pm. While observing the calibrator
display, use a small screwdriver to adjust the flow adjustment screw (located just to
the left of the on/off switch) to adjust the flow rate. Adjustment should be made by
gently turning the screw clockwise or counterclockwise to increase or decrease the
pump flow rate. Make adjustments in partial turns.

5.2.9	Once adjusted to 20.0 ±1.0 1pm allow the flow to stabilize for one minute. After 3
readings, record the average flow rate on the SVOC Air Samples Data Collection
Sheet and Chain of Custody Form in the 'Flow' column. There is space for the
measurement before and after sample collection (Appendix I).

5.2.10	Turn off the pump, remove the "dummy" PUF cartridge from the sample pump
tubing and move-on to check the flow on the other sampling setups.

Sample Collection

5.3.1	The PUF cartridge will be sent wrapped in aluminum foil and stored in a resealable
bag labeled with the sample ID (see Section 5.4 for details). Prior to the anticipated
start of the monitored on-field activity, determine the appropriate sample ID and
retrieve the appropriate bag. Section 5.4 gives details about how the sample media
is labeled. Briefly, the ID numbers will have the form TCRS-R-VV-W-X-Y-Z
where position W (F for field or D for duplicate) and Y (on-field position 1, on-field
position 2, off-field position 8) will help you identify the appropriate filter media for
each sampling station.

Note: The next step will begin handling of the PUF cartridge. Please clean
your hands to the best of your ability using water and kimwipes. For
SVOC sampling, technicians should use clean hands and minimize
contact with the sample cartridge rather than don gloves as most nitrile
gloves contain phthalates that can contaminate these samples.
Technicians can use the aluminum foil that comes wrapped around the
cartridge as a barrier to minimize contact with the sample cartridge.

5.3.2	Remove and unwrap the PUF cartridge being sure to retain the bag and place the
aluminum foil inside to keep it clean. {If the foil becomes soiled, throw it away.)

Figure 2: PUF filter cartridge

5.3.3	Looking at the PUF cartridge, you will see that the caps are two different sizes.
Remove the longer orange/red plug from the smaller/shorter cap and place it into the
resealable bag.

5.3.4	Insert the open end of the PUF cartridge into the vacuum tubing attached to the
sample pump. Secure the PUF cartridge on the sampling stand using the 3-prong
clasp being sure that the clasp is centered on the upper, shorter cartridge cap (see
Fig. 1).

Note: The next step will expose the PUF filter media. DO NOT touch the PUF
plug (white foam-like piece). If you MUST touch the glass tube, do so
with a clean, dry kimwipe or gloves if you must. Gloves should NOT be
worn unless absolutely necessary for cleanliness as compounds from the
gloves may interfere with this SVOC measurement.

5.3.5	Remove the bottom, longer cartridge cap (with the smaller orange plug) and place it
back into the resealable bag. Place the resealable bag in or under the pump or pump
box for safe keeping until sample retrieval. DO NOT separate the resealable bag
from the sampling media as this will increase the likelihood that samples will be
mixed up.

5.3.6	The sampling setup should now look exactly like Figure 1. Double check the length
of tubing and remove any kinks. Adjust the clamp so the inlet to the PUF cartridge
is at 1.0 ± 0.1 meters

5.3.7	Sample collection should be initiated prior to the start of the monitored on-field
activity so that sampling at all three locations is underway at the time the on-field
activity begins. Ideally, sample collection will be initiated within 30 minutes of the
start of the monitored activity (with a maximum time of 60 minutes prior). To
collect field samples, turn on the pump by opening the pump lid and sliding the
on/off switch located on the pump deck to the "on" position (up).


-------
Crumb Rubber SVOC Sampling
D-EMMD-SSAB-012-SOP-01
Page 11 of 22
8/21/2017

5.3.8	Record the sample start time on the SVOC Air Samples Data Collection Sheet and
Chain of Custody Form (Appendix I)

5.3.9	Close the pump lid and settle it into the protective case with the vacuum tubing
pointing up. Double check the tubing for kinks and correct if necessary.

5.3.10	Sampling may continue for a period after participant on-field activities are
completed so that all personal participant samples can be collected as quickly as
possible. Ideally, sample collection will be completed within 30 minutes of the
completion of the monitored activity (with a maximum time of 60 minutes after).
As soon as feasible following the monitored on-field activity, open the pump lid and
turn off the pump by sliding the on/off switch located on the pump deck to the "off
position (down).

5.3.11	Record the sample stop time on the SVOC Air Samples Data Collection Sheet and
Chain of Custody Form (Appendix I).

5.3.12	Retrieve the original resealable bag containing the aluminum foil, cartridge cap, and
orange plug. Double check the sample ID to be sure the sample is appropriately
labeled. Remove the longer cartridge cap from the bag and press it on to the open
end of the PUF cartridge. Detach the PUF cartridge from the vacuum tubing and
insert the long orange plug onto the shorter cartridge cap. Wrap the entire cartridge
back in the aluminum foil (if clean and available, otherwise omit) and place it in the
resealable bag with the sample ID.

5.3.13	Place the sample in the cooler chilled with frozen ice packs until placed into freezer
storage (no higher than -4°C) until they are shipped to the EPA Laboratory (see
Section 5.6).

5.3.14	Repeat the flow rate measurement (described in Section 5.2) and record the stop
flow on the SVOC Air Samples Data Collection Sheet and Chain of Custody Form
(Appendix I).

Labeling the Samples

5.4.1	Labels for these samples will be generated at the EPA lab (using the convention
outlined in Section 5.4.2) and placed on the resealable bags containing the clean
PUF cartridges before they are transported to the field. At the end of sampling
period, the sampled PUF will be returned to this bag in accordance with Section 5.3.

5.4.2	Samples are labeled according to the convention:

TCRS-R-V V - W-X-Y-Z

where:

Page 13 of 22
8/21/2017

ice packs until they can be shipped to EPA. The samples should be shipped back to
the EPA laboratory within two days following sample collection. Samples may be
driven back to the laboratory provided they are stored in a cooler with frozen ice
packs.

5.6.2 For sample shipment, pack the cooler just prior to shipping as follows:

5.6.2.1	Pack the PUF sample cartridges in bubble wrap inside a brown cardboard
box. Tape the box shut and add it to the bottom of the cooler.

5.6.2.2	Add a layer of frozen ice packs to completely cover the storage boxes.

5.6.2.3	Repeat the previous 2 steps as needed until all filter media has been packed
for transport.

5.6.2.4	As available and as necessary to keep the exposed filter media from shifting
and breaking during transport, add any available ice packs to the cooler
followed by unexposed filter media and any padded packing material.

5.6.2.5	Snap a photo of the sample data collection and COC forms (retain in case of
damage during shipping, discard after they are recorded by EPA) and then
add the data collection and COC forms to a resealable bag. Place the bag on
top of the cooler contents and then seal the cooler.

5.6.3	Mail the packed cooler to the EPA laboratory using next day air FedEx or similar
overnight delivery service. Address the shipment to:

US EPA Chemical Services
Kent Thomas or Scott Clifton
109 T.W. Alexander Drive

5.6.4	Immediately notify Kent Thomas (thomas.kent@epa.gov) or Scott Clifton
(clifton.matthew@epa.gov) of the incoming shipment via email. Include the
shipment tracking number.

Quality Control

The quality control requirements will allow assessment of the quality of the samples
collected. Determination of possible contamination and reproducibility of the method will


-------
Crumb Rubber SVOC Sampling
D-EMMD-SSAB-012-SOP-01
Page 14 of 22
8/21/2017

be targeted as data quality indicators.

6.1 Field Blanks and Field Controls

A minimum of 1 field blank and 1 spiked field control will be collected each sampling day.
The project's quality assurance project plan will detail the quality control sample types,
numbers, and deployment plan (see Section B5 of Quality Assurance Project Plan
Addendum for the Tire Crumb Research Study - Exposure Characterization Pilot Study (D-
SED-IEMB-006-QAPP-02)).

6.1.1 As stated in Section 5.2.1, the PUF cartridge will be sent plugged with orange
fittings, wrapped in aluminum foil, and stored in a resealable bag. Resealable bags
containing PUF cartridges meant for field sampling and for field blanks and controls
will be marked with the sample ID (see Section 5.4)

6.1.2	Field blank(s) and field control(s) will be taken to the synthetic turf field along
with the sample filters. The field blank(s) and field control(s) will NOT be
opened or deployed but should be handled just like field samples in that they
should be transported to the field and put into cold storage at the same time as
the field samples. These blanks will NEVER be removed from the resealable
storage bags.

6.1.3	The field blank(s) and field control(s) will be stored and shipped along with the
sample filters.

6.2 Duplicate Samples

Duplicate samples shall be collected at a single on-field location during each day of field
measurement. Two sampling systems (pump/inlets) shall be positioned within 2 meters of
each other and operated as specified in Section 5. The purpose of duplicate samples is to
determination of precision of the sampling method in its entirety.

6.3 BIOS Flow Calibrator Calibration

The BIOS flow meter will be used to determine the flow rate through the sampling media.
Because the unit is equipped with a mass flow controller and because of sampling conditions
(pump not operated at max flow and pressure drop sufficiently low), the flow rate can be
considered stable during sampling.

This BIOS flow meter was calibrated by the manufacturer and no adjustment or additional
calibration of this device is needed. The flow meter should be sent back to the manufacturer
or to another source for re-calibration if it has been greater than 1 year since the calibration

certification date or if flow meter is not operating properly.

7.0 General Sampling Precautions

o Pumps should never be operated without a filter in-line.

o Pumps should be calibrated against the reference BIOS. Calibration should take

place just prior to sampling initiation and after sampling as noted in section 5.2.
o The flow rate will be used in conjunction with the total elapsed sampling time to
calculate total air volumes sampled and integrated analyte concentrations observed
during the sample capture period.

8.0	Possible Corrective Actions for Observed Problems During Sampling

8.1	Pump Failure

o If a pump fails, correct any obvious errors such as kinked lines, battery not fully

charged, etc. If possible, replace the pump or battery,
o Document any pump failures in the data collection sheet.

8.2	Possible Contamination of Filters or Supplies

Clean resealable bags and aluminum foil will be available. Simple replace the contaminated
items being sure to transfer the sample ID sticker to a new resealable bag.

When possible, a spare PUF sampling cartridge will also be sent along. This PUF cartridge
may be used in place of a contaminated cartridge if a field sample cartridge is contaminated
prior to sample collection.

Contact the NERL-EMMD staff scientists for possible replacement items or directions for
decontamination. Be sure to document in the data collection sheets any suspicion of possible
contamination of filters or supplies.

9.0	Recordkeeping

9.1	Data Sheets

All information concerning sample collection will be recorded by the appropriate operator
on the SVOC Air Samples Data Collection and COC form attached in Appendix I.

9.2

Calculations


-------
Crumb Rubber SVOC Sampling
D-EMMD-SSAB-012-SOP-01
Page 16 of 22
8/21/2017

The sample flow rate is directly measured using the average of the pre and post BIOS flow
measurements. The elapsed time in minutes is the sum total of minutes the pump operated
during the sampling episode. A normal 3 hour run period should have approximately 3 hours
X 60 min/hour =180 minutes. Sample volume calculations will be made during data
processing, not as part of the field sampling activities.

Chain-of-Custody

The original of the SVOC Air Samples Data Collection Sheet and Chain of Custody Form
will accompany the filter samples back to the NERL-RTP laboratory. A copy of the SVOC
Air Samples Data Collection Sheet and Chain of Custody Form is attached in the Appendix
I.

Sample collection, shipping, receipt, and analysis will be indicated on the sample COC form
by responsible parties. Original copies of all data forms will be returned to the EPA project
coordinator Kent Thomas (thomas.kent@epa.gov) and maintained in the NERL TCRS
project files.

IMPORTANT SAFETY INSTRUCTIONS

CAREFULLY READ AND
SAVE THESE INSTRUCTIONS

	DOWNLOAD MANUAL	

This manual can be read or downloaded from the BATTERY TENDER®
website @ www.battervtender.com	

WARNING AND CAUTION LABEL DEFINITIONS:

WARNING indicates a potentially hazardous situation which, if not
avoided, could result in serious injury or death.

A CAUTION

CAUTION indicates a potentially hazardous situation which, if not
avoided, may result in minor or moderate injury.

CAUTION

CAUTION used without the safety alert symbol indicates a
potentially hazardous situation, which if not avoided, may result
in property damage.

GENERAL PRECAUTIONS

WARNING

Always charge the battery in a well ventilated area. Explosive
hydrogen gas may escape from the battery during charging. Keep
open flames, electrical sparks and smoking materials away from

the battery at all times. Failure to do so could result in serious
injury or death.

NOTE:

Gas hot water heaters are a source of open flame to be avoided.

CAUTION

Locate the charger as far away from the battery as is allowed by
the length of the output cable harness. NEVER set the charger
above or below the battery. Gasses or fluids from the battery may
corrode and damage the charger.

CAUTION

Do not set the charger on a combustible surface. Locate in a well
ventilated area to dissipate heat generated by the charger.

P/N 3 92-0215-RC

CAUTION

NEVER use a battery charger unless the battery voltage matches
the output voltage rating of the charger. For example, do not use
a 12-volt charger with a 6-volt battery and vice versa.

A WARNING

Do not expose the charger to rain or snow to avoid risk of electric
shock or fire.

A WARNING

Do not use attachments or accessories that are not recommended
or sold by the battery charger manufacturer. Doing so may cause
electric shock, fire, or other unforeseen situations resulting in
serious injury or death.

A CAUTION

When handling electric power cords, always pull by the plug
rather than by the cord. This reduces the risk of damage to both
the plug and cord, and minimizes the likelihood of electric shock.

CAUTION

Make sure all electric power cords are located so that they cannot
be stepped on, tripped over, or otherwise subjected to damage or
stress.

CAUTION

Study all of the battery manufacturer's precautions and specific
recommendations for safe operation such as not removing cell
caps while charging and the recommended rates of charge
(charger output current). This is important to avoid damage to the
battery.

CAUTION

When leaving a battery charger connected to a non-sealed,
flooded battery for extended periods of time (weeks, months,
etc.), periodically check individual cell fluid levels against
manufacturer's recommendations for safe operation.

CAUTION

If the battery releases an excessive amount of gas or if the battery
gets hotter than 130°F (55°C) during charging, disconnect the
charger and allow the battery to cool. Overheating may result in
plate distortion, internal shorting, drying out or other damage.

2


-------
A WARNING

NEVER disassemble the charger or attempt to do internal repairs. Take
it to a qualified service technician. Assembling the charger incorrectly
may result in the risk of electric shock or create a fire hazard. If the
supply cord is damaged, it must be replaced by the manufacturer, its
service agent or similarly qualified persons in order to avoid a hazard.

PERSONAL PRECAUTIONS

WARNING

Battery posts, terminals and related accessories contain lead and
lead components, chemicals known to the State of California to
cause cancer and birth defects or other reproductive harm. Wash
hands after handling.

1.	Someone should be within range of your voice or close enough to come to
your aid when you work near a lead-acid battery;

2.	Have plenty of fresh water and soap nearby in case battery acid contacts skin,
clothing, or eyes;

3.	Wear complete eye protection and clothing protection. Avoid touching eyes
while working near battery;

4.	If battery acid contacts skin or clothing, wash immediately with soap and
water. If acid enters an eye, immediately flood eye with running cold water for
at least 10 minutes and get medical attention immediately;

5.	NEVER smoke or allow a spark or flame in vicinity of battery or engine.

6.	Be extra cautious to reduce risk of dropping a metal tool onto battery. It might
spark or short-circuit battery or other electrical part that may cause an
explosion;

7.	Remove personal metal items such as rings, bracelets, necklaces, and
watches when working with a lead-acid battery. A lead-acid battery can
produce a short-circuited current high enough to weld a ring or the like to
metal, causing a severe burn;

8.	Use the charger for charging a lead-acid battery only. It is not intended to
supply power to an extra low-voltage electrical system or to charge dry-cell
batteries. Charging dry-cell batteries may cause them to burst and cause
injury to persons and damage to property;

NOTE

There are some wet, non-spillable, lead acid batteries on the market whose
manufacturers' make the claim that they are dry-cell batteries. These batteries are
sealed, gas-recombinant, starved electrolyte, possibly with AGM (Absorbed Glass
Matte) type construction. It is perfectly safe to use the INTERNATIONAL
BATTERY TENDER® to charge these types of batteries. The dry-cell battery
warning is intended for non-rechargeable, alkaline and other similar types of
batteries. If you have any doubt about the type of battery that you have, please
contact the battery manufacturer before attempting to charge the battery.

9.	NEVER charge a visibly damaged or frozen battery.

10.	Do not recharge non-rechargeable batteries.

3

PREPARING TO CHARGE

1.	If it is necessary to remove battery from vehicle to charge it, always
remove grounded terminal from battery first. Make sure all accessories in
the vehicle are off in order to prevent an arc;

2.	Be sure area around battery is well ventilated while battery is being
charged. Gas can be forcefully blown away by using a piece of cardboard
or other nonmetallic material as a fan;

3.	Clean battery terminals. Be careful to keep corrosion from coming in
contact with eyes;

4.	Add distilled water in each cell until battery acid reaches level specified by
battery manufacturer. This helps purge excessive gas from cells. Do not
overfill. For a battery without cell caps, carefully follow manufacturers'
recharging instructions;

5.	Study all battery manufacturers' specific precautions such as removing or
not removing cell caps while charging and recommended rates of charge;

6.	Determine voltage of battery by referring to owner's manual and make
sure it matches output rating of the battery charger.

7.	Locate charger:

a.	Locate the charger as far away from battery as the DC cables
permit;

b.	Never place the charger directly above or below the battery
being charged. Gases or fluids from the battery will corrode
and damage the charger;

c.	Never allow battery acid to drip on the charger when reading
gravity or filling battery;

d.	Do not operate the charger in a closed-in area or restrict
ventilation in any way.

e.	Do not set a battery on top of the charger.

8.	Connect and disconnect DC output clips only after setting any charger
switches to the off position and removing AC cord from the electric outlet.
Never allow clips to touch each other.

9.	Follow these steps when battery is installed in a vehicle. A spark near
battery may cause a battery explosion. To reduce risk of a spark near
battery:

a.	Position AC and DC cords to reduce risk of damage by hood,
door, or moving engine parts like fan blades, belts, and
pulleys.

b.	Check polarity of battery posts. A positive (pos, p, +) battery
post may have a larger diameter than a negative (neg, n, -)
post;

c.	Determine which post of battery is grounded (connected) to
the chassis. If negative post is grounded to the chassis (as in
most vehicles), see item (d). If positive post is grounded to
the chassis, see item (e);

d.	For a negative-grounded vehicle, connect the positive (red)
clip from the battery charger to the positive (pos, p, +)
ungrounded post of battery. Connect the negative (black) clip
to the vehicle chassis or engine block away from battery. Do
not connect the clip to carburetor, fuel lines, or sheet-metal
parts. Connect to a heavy gauge metal part of the frame or
engine block;


-------
e.	For a positive-grounded vehicle, connect the negative (black)
clip from battery charger to negative (neg, n, -) ungrounded

post of battery', connect the positive (red) clip to the vehicle
chassis or engine block away from battery. Do not connect
clip to carburetor, fuel lines, or sheet-metal parts. Connect to
a heavy gauge metal part of the frame or engine block;

f.	Connect charger AC supply cord to an electric outlet;

g.	When disconnecting the charger, turn switches to off,
disconnect AC cord, remove clip from vehicle chassis, and
then remove clip from battery terminal.

10. Follow these steps when battery is outside the vehicle. A spark near the
battery may cause a battery explosion. To reduce risk of a spark near battery:

a.	Check polarity of battery posts. A positive (pos, p,+) battery
post may have a larger diameter than a negative (neg, n, -)
post;

b.	Attach at least a 24 inch long 6-gauge (AWG) insulated
battery cable to the negative (neg, n, -) battery post;

c.	Connect the positive (red) charger clip to the positive (pos, p,
+) post of battery;

d.	Position yourself and the free end of cable as far away from
battery as possible, then connect negative (black) charger clip
to free end of cable;

e.	Do not face battery when making final connection;

f.	Connect charger AC supply cord to an electric outlet;

g.	When disconnecting the charger, always do so in reverse
sequence of connecting procedure and break first connection
while standing as far away from the battery as is practical.

USER INSTRUCTIONS

AUTOMATIC CHARGING AND BATTERY STATUS MONITORING: All

BATTERY TENDER® chargers are completely automatic and may be left
connected to both AC power and to the battery that it is charging for long
periods of time. The charger output power, voltage, and current depends on
the condition of the battery it is charging. BATTERY TENDER® chargers have
2 status indicator lights that provide a visual means to determine the operating
mode of the charger and hence the condition of the battery connected to the
charger.

The two-colored status indicator lights are available to determine whether the
charger is operating in one of the 3 primary charge modes: the bulk mode (full
charge, constant current, battery is 0% to 85% charged), the absorption mode
(high constant voltage, battery is 85% to 100% charged), or the storage/float
maintenance mode (low constant voltage, battery is 100% to 103% charged).

When the battery is fully charged, the green status indicator light will turn on
and the charger will switch to a storage/maintenance charge mode. The
BATTERY TENDER® charger will automatically monitor and maintain the
battery at full charge.

5

ELECTRICAL CONNECTIONS BETWEEN THE CHARGER AND THE

BATTERY: Before charging, connect the alligator clips or ring terminals to the
battery terminals. Then connect the charger AC power cord to the AC power outlet.
When you want to disconnect the charger from the battery, first disconnect the charger
AC power cord from the AC power outlet. Then disconnect the charger leads from the
battery terminals.

A WARNING

Always unplug or turn OFF the battery charger before connecting or
disconnecting the charger clamps to the battery. Connecting or disconnecting
clamps with the charger on could cause a spark resulting in a battery explosion.
A battery explosion may rupture the battery case causing a discharge or spray of
sulfuric acid which could result in serious injury or death.

CONNECTIONS FOR ALL LEAD-ACID BATTERY TYPE: (See item 10 under
General Precautions.)

<	In General: First connect the red positive (+) charger output lead to the
positive terminal of the battery. Then connect the black negative (-) charger
output lead to the negative terminal of the battery. However, pay particular
attention to the next two items and the instructions under item 18 under
General Precautions.

<	As an added measure of safety, particularly when working with standard,
flooded, lead acid batteries, UL recommends that the second, negative (-)
charger output lead connection be made to the grounded equipment chassis
rather than directly to the negative battery post.

<	In similar fashion, for positive ground systems, the positive post of the battery
is now at the same electrical potential as the grounded equipment chassis.
Therefore UL recommends that the positive (+) charger output lead
connection be made at the grounded equipment chassis rather than directly
to the positive battery post.

ATTENTION: BATTERY TENDER® CHARGERS HAVE A SPARK FREE
CIRCUITRY. The output alligator clips or rina terminals will not spark when they are
touched together. The BATTERY TENDER chargers will not produce an output
voltage until it senses at least 3 volts from the battery. It must be connected to a battery
with the correct polarity before it will start charging a battery. Therefore, if you plug the
AC power cord into an AC power outlet, and if the output alligator clips or ring terminals
are not connected to a battery, and if you touch the alligator clips or ring terminals
together, there will be no electrical spark.

NOTE:

THE OUTPUT CLIPS OR RING TERMINALS MUST BE CONNECTED TO A
BATTERY BEFORE THE CHARGER CAN PRODUCE AN OUTPUT VOLTAGE.

If the charger is hooked up backwards, the amber light will continue flashing
(International Plus and EUR0400), indicating that a charge has not been initiated
(WP800 does not show any light at all). The alligator clips or accessory ring terminals
must be connected to the battery, with the proper polarity, Red to Positive (+ output to
+ battery post) and Black to Negative (- output to - battery post), before the charger will
generate any output voltage.

6


-------
WORKING WITH A DEAD BATTERY OR A BATTERY WITH A VERY
LOW VOLTAGE:

If you try to charge a dead battery having a voltage below 3 Volts, BATTERY
TENDER® chargers will not start. An internal safety circuit prevents the
BATTERY TENDER® chargers from generating any output voltage unless it
senses at least 3 Volts at the charger output. In this situation, the amber light will
continue to flash (International Plus and EURO400), indicating that a charge has
not been initiated (WP800 does not show any light at all).

NOTE:

If a 12 Volt, Lead-Acid battery has an output voltage of less than 9 volts when it is
at rest, when it is neither being charged nor supplying electrical current to an
external load, there is a good chance that the battery is defective. As a frame of
reference, a fully charged 12-Volt, Lead-Acid battery will have a rest-state, no-load
voltage of approximately 12.9 volts. A fully discharged 12-Volt, Lead-Acid battery
will have a rest-state, no-load voltage of approximately 11.4 volts. That means
that a voltage change of only 1.5 volts represents the full range of charge 0% to
100% on a 12-Volt, Lead-Acid battery. Depending on the manufacturer, and the
age of the battery, the specific voltages will vary by a few tenths of a volt, but the
1.5-volt range will still be a good indicator of the battery charge %.

STATUS INDICATING LIGHTS: If neither light is lit, then the battery is not
properly connected and/or the charger is not plugged into AC power. The

following describes light operation:

<	AMBER LIGHT FLASHING - The amber light flashing indicates that the
battery charger (International Plus and EUR0400) has AC power available
and that the microprocessor is functioning properly. If the amber light
continues to flash, then eitherthe battery voltage is too low(less than 3volts)
or the output alligator clips or ring terminals are not connected correctly.

<	AMBER LIGHT ON STEADY - Whenever the amber light is on steady, a
battery is connected properly and the charger is charging the battery. The
amber light will remain on until the charger completes the charging stage.

<	GREEN LIGHT FLASHING - (International Plus and EUR0400 only) When
EUR0400 shows a green light flashing, the battery is 80% charged and may
be used if necessary. When the green light is flashing, and the amber light is
on (International Plus), the battery is greater than 80% charged and may be
removed from the charger and used if necessary. Whenever possible, leave
the battery on charge until the green light is solid.

<	GREEN LIGHT ON STEADY - All chargers: When the green light stops
flashing and burns steady, the charge is complete and the battery can be
returned to service if necessary. It can also stay connected to maintain the
battery for an indefinite period of time

STATUS INDICATING SYMBOLS: The following symbols are located next to the
status indicator lights.

—1=1	1=1— The symbol next to the AMBER light represents a partially charged

battery. The solid band across the bottom is green in color. The

	 background is yellow. The green area indicates the charged portion of

	 the battery and the yellow area represents the uncharged portion.

—1=1	1=1— The symbol next to the GREEN light represents a fully charged

battery. The entire area inside the battery outline is green.

2.0 Unpacking Checklist

Your DryCal DC-Lite has been packaged with care and includes all components
necessary for operation. Please take a moment to check that you have received
the following items. If you believe you have not received a full shipment or have
any other questions, please contact Bios immediately.

Your DryCal DC-Lite Includes

•	Single-Station Battery Charger

•	Tubing Kit

•	Additional High FlowTubing (with DCL-MH and DCL-H only)

•	Certificate of Calibration

•	Instruction Manual

•	Registration Card

3.0 General Description

The DryCal DC-Lite is a field-portable primary flow calibrator used for industrial
hygiene, environmental and laboratory flow measurement applications.
The DC-Lite uses patented dry piston technology and infrared sensors to obtain
volumetric flow rates quickly and accurately.

Housed in a small, sturdy case, each unit employs a variety of popular user con-
veniences such as push-button read and auto-read functions, a large alphanumeric
display, battery level indicator, 5-minute automatic shut-off and a parallel printer
port for data-logging.

4.0 Theory of Operation

The DryCal DC-Lite can be used to measure air flow rates for either a vacuum flow
source (connected to the outlet port) or a pressure flow source (connected to the
inlet port). Before a reading is initiated, or between readings, a computer-directed
valve performs a bypass function.This allows the air to pass through the DryCal
valve, bypassing the flow-measuring cell which is then able to reset.

As a reading is initiated (by pressing the Read button) the internal valve closes
and the flow source evacuates or pressurizes the air in the flow-measuring cell.The
piston rises at the rate of evacuation or pressurization. A precision encoder system
provides two finely collimated light beams with a known distance between the
beams.

After a suitable acceleration interval the piston breaks the first infrared light beams
as it passes.The flow reading is completed when the second infrared beam

3


-------
is broken. A crystal clock measures the time interval as the piston passes the two
infrared light beams. The internal computer then calculates the volumetric flow
based upon these parameters.

After a completed cycle, the valve is opened by the computer and the piston
resets. The flow measurement is instantly displayed on the LCD in milliliters
per minute (ml) or liters per minute (L).

Any time the valve is open, the air flow is allowed to pass through the DryCal
valve, bypassing the flow-measuring cell.

5.2	Turning the Power On

The DC-Lite has an energy saving 5-minute auto shut-off feature.

1	Press the On button to turn the DC-Lite on.

2	An initializing screen will display the microprocessor revision number,
then the standard screen will be displayed.

5.3	Disabling & Re-Enabling the 5-Minute
Auto-Shutoff Feature

5-minute auto-shutoff is the default setting for the DC-Lite.This feauture can be
disabled if your application requires a longer standby time.The 5-minute
auto-shutoff feature must be disabled each time the unit is powered on or reset.

The DC-Lite features protective circuitry that prevents the battery from becoming
over-depleted. If the battery is allowed to become too weak, the DC-Lite may
automatically shut off due to low battery voltage.This is more likely to occur more
if the 5-minute auto-shutoff feature is disabled.

Disabling the 5-minute auto-shutoff feature

1	Press and hold the Read button, then press the On button (or the Reset
button if the unit is already on).

2	The display will read, "Auto-Off Disabled" until the Read button is released.

Re-enabling the 5-minute auto-shutoff feature

With the unit on, push the Reset button.

5.4	Taking Readings

Taking Single Readings

The inlet and outlet ports are located on the right side of the unit.The lower
port is for suction (outlet) and the upper port is for pressure (inlet). All successive
readings will automatically be used to calculate the average flow. The unit
will automatically clear the average after ten readings and begin averaging
a new sequence.

A reading has been initiated when the green LEDs in the flow cell viewing
window turn on, the valve can be heard closing and the piston begins to move
up the flow cylinder.

1 Connect tubing between the flow source and the DC-Lite with sampling
medium in-line if the application requires it.Turn the DC-Lite and
flow source on.

5


-------
2	Press and release the Read button to obtain a single flow measurement.
The flow measurement will appear on the LCD.

3	Continue this procedure to obtain the required number of flow readings.

Taking Auto-Repeat Readings

Readings can be taken continuously in the auto-repeat mode for hands-free
operation. The unit will automatically clear the average after ten readings
and begin averaging a new sequence.

1	Press and hold the Read button until a reading starts then release.

This will begin a continuous read session.

2	To stop the continuous read session, press the Stop button once.

The display will indicate the current flow reading (Flow), the average flow
value (Average) and the number of readings in the average (Number
in Average) up to 10.

5.5	Resetting the Averaging Sequence

The number of readings in an averaging sequence can be reset to (00) at any time
by pressing and holding the Stop button for 2 full seconds.

5.6	Printing

The DC-Lite must be turned on prior to connecting a printer cable to the back
of the unit. Failure to do so will result in the display reading "Nexus Control."

If this occurs, remove the printer cable and reset the unit using the white recessed
Reset Button located on the back of the unit as described in Section 5.10.

The DC-Lite does not support any printers except those supplied by Bios.The DC-
Lite sends basic ASCII text in IBM/Centronics parallel format to a printer. Although
it may work with older and some stand-alone, IBM-compatible office printers
(printers that do not require drivers to be installed on an attached computer in
order to operate), we do not recommend their use.

If you wish to experiment nonetheless, try the "Wide 1" and "Wide 2" formats to
test compatibility. You may get one page per line or other incompatible results.

Bios offers the BP-1 stand-alone battery powered printer for hard copy output of
DryCal data.This printer is small, portable, convenient and easy to use. It makes an
excellent dedicated printer for use with Bios products.

Bios cannot guarantee compatibility with any printer other than the Bios BP-1
portable thermal printer.

6

Print Setup

1	The flow source should be turned on and connected to the appropriate
air boss on the right side of the DC-Lite.

2	Turn the DC-Lite on before connecting the printer cable. Failure to do so will
result in the display reading "Nexus Control'.' If this occurs, remove the printer
cable and reset the unit using the white recessed Reset Button located on
the back of the unit as described in Section 5.10.

3	Plug the printer cable into the parallel printer port located on the back of
the DC-Lite. Make sure DC-Lite and the printer are on.

Selecting a Print Setting

After the printer setting selection has been made a print mode selection

(All, 10 or Off) must also be made to initiate printing. The Print button will toggle

between three print settings.

1	The default setting is "Off." When the power is turned on the printer
setting will always be in the "Off" position.

2	To engage the printer, press the Print button once for the "Print 10" setting
(this will allow the printer to print ten readings and stop). Press the Print
button twice for the "Print All" position (to print continuously).

3	After the printer setting selection has been made, a Read mode selection
(single or auto) must also be made to initiate the flow measurement process
as described in Section 5.4.

5.7	Stop & Reset

A flow reading can be stopped at any time by pressing and releasing the Stop
button. This process opens the valve and allows air to bypass the flow-measuring
cell. The piston will fall to the bottom of the flow-measuring cell.

The DC-Lite can be reset by pressing and holding the Stop button for two full
seconds. During a reset, the display is cleared and the number of readings in an
averaging sequence is reset to zero.

5.8	Resetting a Printed Sequence

When connected to a printer, the reset process initiates a printed heading for a
sequence of readings and resets the number of readings in an averaging sequence
to zero. The printed heading includes a column for each flow reading (Flow), the
running average (Average) and the number of samples in the average (# Samples).

7


-------
5.9	Printing to a PC

Bios International offers a parallel-to-serial converter kit, part PSC-1, that allows
the information from a DC-Lite to be printed to a computer via the HyperTerminal

TM

utility included with Microsoft1 Windows .

This information can be imported into many commonly used spreadsheet
programs, such as Microsoft Excel or Quattro Pro.The DryCal parallel-to-serial
converter kit includes everything you will need to print flow readings from your
DryCal to a Windows-based PC.

Bios International only guarantees compatibility with parallel-to-serial converters
purchased through Bios International. Bios International does not offer technical
support on serial port configuration. For assistance with determing the correct
Com Port number or port configuration, please contact your IT professional.

5.10	Hard Reset Button

If for any reason the DC-Lite does not respond to push-button commands, it may
be necessary to reset the instrument. For this purpose there is a white recessed
button on lower right side of the back panel near the parallel printer port.The but-
ton resets the unit back to the initializing screen and the printer setting will revert
to the "Off" position. Before resetting, be sure to remove the printer cable from
the back of the DC-Lite. Failure to do so will result in the display reading "Nexus
Control." If this occurs, remove the printer cable and reset the unit again.

6.0 Battery System

The DryCal DC-Lite is powered by an internal lead-acid battery.The battery will
power the instrument for 6-8 hours of continuous use and has a typical service life
of approximately 2-5 years, depending on use. The DC-Lite provides a convenient
5-minute automatic shut-off feature to extend battery life. Use of a printer does not
affect the battery life.

The DC-Lite can be charged by the Bios single-station charger when plugged into
a standard 115V AC power source outlet (220V AC optional). Provided that the
battery has sufficient charge to operate the DC-Lite, the DC-Lite can be charged
indefinitely using the AC wall adapter provided.

Although the DC-Lite may be plugged into AC power, if the battery is exceptionally
weak the DC-Lite may not function. Please read all setup and charging instructions
indicated in this manual before using equipment.

8

6.1	Charging the Battery

Before using your DryCal DC-Lite, be sure that the battery system has been fully
charged to ensure that unit will perform without interruption. Using the DC-Lite
with a low battery will not affect the product's accuracy.

The DC-Lite is equipped with a battery indicator that provides battery charge
indication at three levels. When the battery indicator on the display is empty the
unit will continue to operate for a limited period of time before shutting itself off.

To Charge the DC-Lite

To view the actual charging status during the charging period, disconnect the
battery charger and wait 3-5 minutes. When the indicator is solid black the battery
is fully charged. Bios recommends leaving the DC-Lite on charge when not in use
to prevent battery degradation.

1	Connect only the appropriate Bios 12VDC charger, provided with the DC-Lite
calibrator, into a standard wall outlet.

2	Insert the charger barrel plug into the charging jack located on the right side
of the DC-Lite housing above the inlet and outlet air bosses. A green Charge
LED will illuminate while the unit is charging. Full charge takes 8 to 12 hours,
and the DryCal can charge while being used.

6.2	Battery Maintenance & Storage

The DC-Lite's lead-acid battery will not exhibit the memory effect common to
nickel-cadmium batteries. It may be left on charge for an indefinite time period
without damage.

Long-term storage without charging can damage the battery pack,
therefore if the DC-Lite cannot be left charging continuously, it should be
fully charged at least once every three months and should be placed in
storage only after achieving a full charge.

7.0 Isolating the DryCal from Other Instruments

The DryCal DC-Lite will mimic the flow source being used.Therefore, if the flow
source exhibits air flow pulsation, Bios recommends the use of an isolation device.

Use of a 25mm, 0.8m filter cassette makes a suitable load for most flow rates used
in industrial hygiene applications.This method stabilizes variations in flow due
to the slight pulsation caused by the stroke of the pump's piston.

In addition, when taking flow readings with the DryCal DC-Lite, an internal valve
closes, placing an insertion pressure spike into the flow stream. Generally, the

9


-------
pressure spike is invisible to the flow source; however, it can cause an interaction
with some instruments (example: some mass flow controllers, Magnehelic
manometers and rotameters). The most common solution is to isolate the DryCal
with a restriction as described in Sections 7.1-7.4.

7.1	Use with Instruments that Contain Internal
Mass Flow Controllers (MFCs)

For some flow instruments with MFCs and large dead volumes (example: some
PM 2.5 monitors) results may not correlate between the instrument's display and
the DryCal.To eliminate these discrepancies, Bios offers an active regulation
device, part DC-IR-H, to provide a constant insertion pressure.

7.2	Use with Personal Air Samplers

The DryCal DC-Lite may be used to calibrate or check the flow rate of personal air
samplers.To ensure accurate flow calibrations, Bios recommends the use of an
isolating flow restriction as described in Section 7.0. A standard MSHA approved
respirable dust filter or equivalent 25-37 mm 0.5 micron casette should be suffi-
cient to provide an appopriate isolation.

7.3	Calibrating Rotameters

When calibrating rotameters the DryCal DC-Lite should be used as a transfer
standard only. Do not use the DC-Lite in series with a rotameter. For optimum
accuracy, use a rotameter over its mid-range.

1	Attach an isolating load or sample medium, with a pressure drop of about
8 to 12 inches of water column, in series with a stable pump and a DryCal.

2	Calibrate the sampling pump at the desired flow setting (ie: 2.00 Lpm)
with the DryCal. When the desired flow setting is obtained, disconnect the
DryCal and attach the tubing to the outlet boss of the rotameter.

3	When the rotameter ball stabilizes, mark the rotameter for the true flow
rate (2.00 Lpm for example) using tape and a permanent marker to denote
the calibrated flow setting or note the point on a rotameter flow chart.

Repeat this procedure for any additional flow settings.

7.4	Use with Magnehelic Manometers

High-capacitance spring-loaded gauges such as Magnehelic manometers can
cause vibration of the DryCal piston.This is not a defect in the DryCal. The piston is

10

accurately mirroring the transient internal vibrations of the gauge. This type of
gauge must be isolated from the DryCal by inserting a suitable restriction between
the gauge and the calibrator

8.0	Maintenance, Quality Assurance

Although the DryCal DC-Lite is a rugged instrument, certain care and maintenance
requirements must still be met.

Current service and calibration information and pricing can be found at
www.biosint.com/service/dclite.htm.

8.1	Maintenance

When not in use always store your DC-Lite in a clean, dry environment. When
possible leave the unit on charge. Wipe only with a damp cloth and do not spray
with liquid solvents or use abrasive cleaners.

8.2	Leak-Test Procedure

A quality assurance self-test feature is provided to verify proper integrity
of the flow cell. It is recommended that the self-check leakage test be conducted
periodically as part of an on-going quality assurance program.

Passing the leak test does not ensure proper function of the DC-Lite. It does
ensure that total leakage is within the product's allowable limits. To ensure proper
function of the DC-Lite annual factory calibration is recommended.

To Initiate the Leak-Test

The leak-test tubing accessory is a short piece of latex tubing with a red plug
that is found in the tubing kit shipped with your DC-Lite. Place the leak-test
tubing accessory over the top (inlet) air boss.The low flow range DC-Lite requires
a miniature leak-test tubing accessory that is supplied in addition to the
standard tubing kit. Any maintenance to the DryCal must be performed by Bios
maintenance personnel.

1	Press and hold the Stop button while pressing the On button. If the DC-Lite
is already on, press and hold the Stop button while pressing the hard reset
button on the back of the unit as described in Section 5.10. After a leak-test is
initiated, the display will read "LeakTest, Invert & Push Read."

2	Invert the DC-Lite so the piston moves to the top of the cell. While the piston
is resting at the top of the cell press the Read button and the internal

11


-------
valve will close. Return the unit to an upright position and it will time the
descent of the piston.

3	Place the DC-Lite on a flat, vibration-free surface.

4	Observe the location of the piston to ensure that it is at the top of the cell
when the test begins (the test may take as long as 15-20 minutes). If the
test is completed successfully, the display will read: "Test OK Push Read."

5	Push the Read button as directed and the internal valve will open
and the piston will fall.

6	Repeat the test with the leak-test tubing accessory connected to the
lower (outlet) air boss. If the unit fails the Leak-test, the display will
read: "Maintenance Reqd Push Read."

8.3 Air Containing Particulates

As of January 1, 2001, the DryCal DC-Lite comes standard with either a 5-micron or
30-micron inlet filter inside the inlet fitting (depending on model ordered).
Additionally, all older DC-Lites sent in for calibration will be retrofitted with new
style inlet filters, free of charge. However, air containing cigarette smoke or other
excessive dust and particulates should be additionally pre-filtered. An additional
particulate filter, part AF-516, is available for this purpose. The filter should be
placed ahead of the DryCal in the flow stream, on the inlet side.

8.4 Return Authorization

Prior to returning your DryCal for repair or recalibration, please contact Bios
International for technical support, troubleshooting assistance and an RMA
number if necessary.

You can telephone Bios at (800) 663 4977 or (973) 492 8400, or send an email to
service ® biosint.com.

8.5 Shipment

When shipping the DryCal DC-Lite please ensure that the packaging is adequate
to protect the instrument. When possible the DC-Lite should be shipped in
the original packaging. Bios International Corp. is not responsible for damage that
occurs during shipment.

8.6 Long-Term Storage

DryCal calibrators can remain on charge until needed without causing damage
to the battery. If the DryCal is stored for long periods of time the battery should be

12

charged at least once every three months.

Always store DryCal calibrators in a clean, dry environment and recharge
the unit prior to use after long-term storage.

8.7 Calibration

As a quality assurance measure, Bios recommends annual calibration of all meas-
urement instruments, although how often you have your DryCal calibrated is
an internal quality control decision. The determining factors are whether the unit
passes the internal leak-test, quality system requirements if applicable, and
the conditions in which the unit is used. Units used in a laboratory setting may
require calibration less frequently than a unit that is used in a dusty environment.
The annual calibration program is an elective and is therefore not included as
a warranty item. "As received" flow test data and expedited "48 hour" turnaround
service are also available at an additional cost. Please contact the factory for more
information on available calibration services and pricing.

Calibration Includes

•	Cleaning (if required)

•	Valve adjustment (if required)

•	Battery capacity test

•	Internal computer program upgrade as necessary

•	Mechanical upgrades as necessary

•	Dynamic Performance Test

•	NIST-Traceable Calibration Certificate

9.0 Calibration Statement

The DC-Lite is dynamically tested by comparing it to a Laboratory Standard pri-
mary piston prover of much higher accuracy (±0.25%), but of similar operating
principles. Flow generators of ±0.01% stability (included in prover accuracy) are
used for the comparison. Use of provers of similar construction to the devices
under test assures the validity of the flow generator as a transfer standard.

The primary Laboratory Standards are qualified by direct measurement of their
dimensions (diameter, length of measured path, time base) against NIST-traceable
gauges and instruments. A rigorous analysis of their accuracy in accordance with
the International Guide to Uncertainty in Measurements has been performed,
assuring their traceable accuracy.Test procedures assure temperature matching of
the Laboratory Standards to the devices under test.

The calibration dates of the laboratory standards for each parameter (diameter,

13


-------
encoder spacing, time base) are included in our calibration reports, along with
identification of the devices used for calibration, their calibration dates and NIST
calibration numbers.

1.0 Scope and Application

This method applies to the collection of air samples from stationary locations on or near synthetic
turf fields with crumb rubber infill. Samples will be analyzed for a suite of volatile organic
compounds (VOCs). This SOP incorporates many of the procedures previously detailed in standard
operating procedure (SOP) D-EMMD-ABQ-004-SOP-01 (Formerly ECAB-152.1) "SOP for
Carbopack X Sorbent Tube Handling: Field Deployment and Shipping." The streamlined field
deployment checklist in this SOP will be useful to field operators.

2.0 Summary of Method

Portable, battery operated, air sampling pumps attached to 3.5-inch x % inch o.d. stainless steel
thermal desorption (TD) tubes packed with Carbopack X adsorbent are used to capture gas-phase
VOCs from ambient air. Air samples are collected from two stationary locations (duplicate samples
at one of these locations) at each synthetic field as close as possible to where activities occur
without posing an obstruction or safety hazard. A third location will be sampled upwind and at a
sufficient distance from the field to represent background.

4.0 Precautions

The sampling systems are powered by internal battery packs. The battery pack must be completely
charged before operating the pump. The battery and pump system should be protected from
excessive heat or cold (<-4 °F, >104 °F) as specified in the operator's manual.

Sampling will take place at outside and inside activity fields. Equipment should be shielded as
much as possible from moisture and should not be used during periods of heavy rain (protective
enclosures are not provided). Sampling stands should be set up so that they are provided protection
from tampering. Sampling stands must also be placed and secured such that no harm will come to
children or others playing in the vicinity of the equipment.

5.0 Personnel Qualifications

Required training is provided by the US EPA. Sample collection will be conducted by qualified
scientific staff trained in the use of the specific field monitoring equipment. Training will include
a demonstration and hands-on training by qualified persons with air sampling expertise. At a
minimum, all SOPs and operating instructions will be reviewed, understood, and followed exactly
by the field staff. Training records will be maintained by the EPA exposure study project lead
(currently Kent Thomas).

Quality Control and Quality Assurance

The quality control requirements will allow assessment of the quality of the samples collected.
Determination of possible contamination and reproducibility of the method will be targeted as data
quality indicators.

7.1	Field Blanks and Field Controls

A minimum of one field blank and one field control will be collected on each sampling day.

As stated in Section 8.4.2, the thermal desorption tubes will be sent sealed with brass
fittings, secured in glass culture tubes, and stored in a metal can. Metal cans containing
thermal desorption tubes meant for field sampling and for field blanks will be pre-labeled
with sample ID codes.

Field blanks and controls will not be removed from their packing in the metal can; they
will remain sealed and returned to the laboratory.

7.2	Duplicate Samples

Duplicate samples will be collected at a single on-field location during each day of field
measurement. Two sampling systems (pump/inlets) shall be positioned on the same
sampling tripod and operated as specified in Section 8.3. The purpose of duplicate samples
is to determine the precision of the sampling method in its entirety.

7.3	Mesa Labs Defender Flow Calibrator

The Mesa Labs Defender flow calibrator will be used at the beginning and end of each
sampling period to measure the pump flow rate. The flow calibrator should have been
certified within the past year by the manufacturer or the flow rates verified against a unit
that is under current certification and deemed appropriate (within 2%). The sampling pump
is equipped with a flow controller and the flow rate is stable during sampling.

Procedures

8.1	General Sampling Considerations

•	Samplers must be placed in an area representative of the average ambient conditions (i.e.,
away from roadways, parking lots or high traffic areas).

•	Pump flow rates are measured using the Mesa Labs Defender. Flow measurements should
take place immediately prior to and immediately after sampling as noted in sections 8.5.5
through 8.5.14.

•	The flow rate will be used in conjunction with the total elapsed sampling time to calculate
total air volumes sampled and integrated analyte concentrations observed during the
sample capture period.

8.2	Pre-Deployment Preparation

•	Charge batteries and flow meter

•	Test sampling pumps

•	Clean field supplies (forceps, glass culture storage tubes, trays, etc.)

•	Condition TD tubes for use

•	Prepare spiked tubes for use as field controls and lab controls

•	Pre-label glass culture tubes and data collection forms with sample codes.

•	Pack all field supplies

8.3	Pump and Sampling Equipment Set-up

8.3.1	Transport the sampling setup and flow measurement equipment to the field location (listed
in sections 6.1-6.6). This will include sampling pumps, sampling stands, vacuum tubing,
and measuring tape along with the data collection sheets, flow meter, pen, and any
materials needed to secure the monitoring site.

8.3.2	Three sampling sites will be identified for each location. Two sites will be located on the
activity field. One site will be located off of the field, in an upwind position if possible.
One sampler will be located at each site and an additional sampler will be positioned at one
of the on-field locations (using same tripod stand) to collect duplicate samples.

Note: Ensure that the information regarding specific site locations and conditions have
been recorded as meta data (on the sheet shown in Appendix C) according to SOP D-SED-
IEMB-005-SOP-01.

8.3.3	Figure 1 shows the sampler configuration with major components identified. Use this
diagram to setup each sampling location.


-------
Crumb Rubber VOC Active Sampling
D-EMMD-AQB-024-SOP-01
August 23,2017
Page 7 of 20

Figure 1: VOC Sampler Configuration

1.	Set up the sampling stand by spreading the tripod base and extending the vertical rod
The tripods are each outfitted with a TD tube holder, a Radiello passive tube holder
(see SOP D-EMMD-AQB-019-SOP-01 for Radiello deployment procedures) and a
metal plate to mount the pump.

2.	Connect one end of the tubing to the hose barb found on the pump. The attached hose
should be snug and not easily removed without the use of applied force. Attach the
pump to the metal plate on the tripod such that the pump is between the plate and the
tripod post. This will provide some shielding to the pump.

3.	Turn the pump on by sliding down the protective cover, pressing any keypad button to
activate the pump, and using the up (A) or down (V) arrow buttons simultaneously to
toggle from "Hold" to "Run:' Allow the pump to run while the rest of the equipment
is being set up.

4.	Adjust the tripod so the TD tube inlet is at a height of 1.0 - 0.1 meters (35.4 in. - 43.3
in.) above ground level.

8.4 Sample Setup

8.4.1	Refer to SOP D-EMMD-ABQ-004-SOP-01 for instructions on handling the TD tubes.

8.4.2	The TD tubes will be sent with the inlets capped with brass fittings, sealed in glass culture
tubes, and stored in a metal can. Thermal desorption tubes meant for field blanks and
controls will be labeled as such. Tubes meant for sampling will be pre-labeled with the
appropriate sample ID codes. Spare sampling tubes will be shipped to the sampling
locations and can be used in the event of damage to the pre-labeled sampling tubes. Be sure


-------
Crumb Rubber VOC Active Sampling
D-EMMD-AQB-024-SOP-01
August 23,2017
Page 8 of 20

to retain the fittings, culture tubes, cans, and packaging for return to the laboratory for
future use.

8.4.3	To set up sampling, determine the appropriate sample code and sampling location. Enter
the TD tube ID number of the pre-labeled tube on the corresponding Data Collection and
COC Record Form.

8.4.4	Immediately before sampling is set to begin, don a pair of nitrile gloves and remove the
glass-enclosed TD tube from the metal can labeled with the field sampling date. Remove
the vial cap and then the Teflon strips from the culture tube one at a time. Remove the
Teflon strips using forceps and place them on a clean surface such as a laboratory tissue or
clean aluminum foil. Next remove the TD tube from the glass culture tube and return the
Teflon strips to the glass culture tube.

8.4.5	Remove the brass fitting from the outlet side (non-grooved end) of the TD tube and insert
this end into the vacuum tubing. Gently place the brass fitting back into the glass culture
tube. Secure the TD tube to the sampling stand using the clamp. Ensure that the other end
of the vacuum tubing is attached to the pump inlet.

8.4.6	Remove brass fitting from the inlet side (grooved end) of the TD tube and place it back
into the glass culture tube, and then return the glass culture tubes to the metal can. The
sampling setup should now look exactly like Figure 1. Double check the length of tubing
and remove any kinks.

8.5 Conducting Active Sample Collection

8.5.1	To collect field samples, turn on the pump by sliding down the protective cover, press any
keypad button to activate the pump, and then press both the up (A) and down (V) keys
together to turn the pump on. Allow the pump to run for at least five minutes to warm-up
and stabilize.

Note: The up (A) and down (V) keys pressed at the same time toggle from "Hold" to "Run"
and from "Run" to "Hold".

8.5.2	The pump flow rate should be set to 100 mL/min in the laboratory prior to field
deployment. This will minimize the amount of time required to fine adjust the pump flow
after the TD tube is attached.

Note: Refer to the pump manual for complete instructions on how to adjust flows. Basic
flow adjustment instructions are shown on the PocketPump Quick Guide in Appendix B.

8.5.3	Insert the non-grooved end of the TD tube into the Swagelok fitting of the Tygon tubing
sample train and tighten the knurled nut finger tight. Insert the TD tube into the mounting
bracket on the sampling stand by inserting the grooved end of the TD tube into the "ears"
of the mounting bracket. This is the sample start time.

8.5.4	Record the sample 'Start Time' on the Data Collection and COC Record Form (Appendix A).

8.5.5	Measure the air sampling flow rate through the TD tube by attaching the grooved end of
the TD tube to a length of Tygon tubing that is then attached to the upper port (suction) of
the Mesa Labs Defender flow calibrator. Press the "ON" button (lower right corner) of the
flow calibrator and hold for approximately one second until the display lights up and the
optical light in the cell illuminates.


-------
Crumb Rubber VOC Active Sampling
D-EMMD-AQB-024-SOP-01
August 23,2017
Page 9 of 20

Note: If the on button is depressed too long it will turn the unit off and you must then press
the "ON" button again to turn on.

8.5.6	The display should show the Defender information and highlight the word "Measure."
Press the Enter button twice to begin flow measurements. This will activate the unit to
make continuous measurements and automatically average 3 replicate readings.

Note: Be sure that the Defender unit is set up to measure the volumetric flow rate in units
of mL/min. Do not measure as STP. Refer to the manual on how to change the setup
features.

Note: If the Defender unit is used in bright sunlight, the flow cell may need to be shielded
in order for the sensors to work properly. Simply hold the unit close to your body or hold
the unit in a shaded area while taking the readings.

8.5.7	Observe the flow rate values being displayed. Flow rates should be 100 ± lOmL/min.

8.5.8	If needed, adjust the flow rate to 100 ± 10 mL/min. While observing the calibrator display,
use the up and down arrow buttons on the pump keypad to adjust the flow. The security
code A V ~" must be pressed in sequence within 10 seconds to change operating
parameters (refer to Appendix B for full details).

8.5.9	Once adjusted to 100 ± 10 mL/min allow the flow to stabilize for one minute, reset the
calibrator by pressing the "Stop" button followed by holding the "Read" button for three
seconds. The unit will automatically collect three flow readings and average them. Record
the average flow rate of the three readings on the datasheet in the 'Start Flow' column of
the Data Collection and COC Record Form (Appendix A).

8.5.10	Remove the flow calibrator tubing from the TD tube and attach the TD screen inlet to the
grooved end of the TD tube.

8.5.11	Close the protective sliding cover on the pump and attach it into the bracket near the bottom
of the sampling stand with the vacuum tubing pointing out. Double check the tubing to
verify there are no kinks.

8.5.12	After sampling for the desired time period (presumed to be an approximate three-hour
duration), re-check the flow and record the average flowrate in the 'Stop Flow' column of
the Data Collection and COC Record Form. To do so, simply remove the inlet screen from
the TD tube, attach the flow calibrator with the Tygon tubing, turn on the flow calibrator,
measure three readings, and record the average reading on the form. No stabilization wait
time is required as the pump has been running continuously.

8.5.13	Open the pump protective sliding cover and turn off the pump by pressing the up (A) and
down (V) keys simultaneously to toggle pump mode to "Hold." The pump enters "sleep"
mode after five minutes in "Hold" without activity (there is no manual off option).

8.5.14	Record the sample 'Stop Time' on the Data Collection and COC Record Form (Appendix A).

8.5.15	Retrieve the glass culture tubes containing the brass fittings from the metal can. Make sure
the label on the glass vial and the TD tube ID (etched on the TD) match those shown on


-------

the data sheet. Don a clean pair of nitrile gloves. Remove the TD tube from the mounting
bracket and remove the inlet screen. Place the brass fitting caps on the TD tube. Hand
tighten the brass fittings and then tighten an additional one-eighth turn using the CapLok
tool. Perform the tug test described in SOP D-EMMD-ABQ-004-SOP-01 to ensure that the
caps are properly tightened.

Note: Do not overtighten the brass nuts as it may distort the metal body of the TD tube or
be hard to remove. Only a small fraction past finger tight is required.

8.5.16	Open the glass culture tube and place the lid onto the metal tray or clean surface.

8.5.17	Retrieve the TD tube. Gently transfer the TD tube to the labeled glass culture tube (Figure
2) being sure that the glass culture tube has a Teflon chip in the bottom to provide
cushioning. Insert the two Teflon strips into the glass culture tube one at a time in order to
minimize stress on the glass.

t & m)

8.5.18	Replace the cap to the glass culture tube.

8.5.19	Place the glass culture tube (containing TD tube) into the cardboard sleeves in the metal
can and place the two foam discs at the top of the can between the metal lid and the culture
tube tops. Securely place the metal lid back on the can.

8.5.20	Samples should be stored at room temperature and shipped back to EPA the day of or the
day after collection (see Section 8.8).

8.6 Labeling the Sample

8.6.1 Labels for these samples will be generated at the EPA lab (using the convention outlined
in Table 1.). The labels will be placed on the glass culture tubes and on the data collection
fonns before they are transported to the field

8.7	Pump/Equipment Take Down

1.	Remove the sample pump from the tripod stand.

2.	Disconnect the tubing from the sample pump and return pump to its protective case.

3.	Re-pack all supplies into their original shipping containers and prepare for transport of
all supplies to the EPA laboratory.

8.8	Return Samples to the EPA Laboratory

1.	All samples should be shipped back to the EPA laboratory as soon after sampling is
complete as possible.

2.	Pack the sample cooler immediately prior to shipping by placing as many as three metal
cans into the cooler and replacing the associated packing material on top of the cans to
prevent the contents of the cooler from shifting. Photocopy or photograph the Data
Collection and COC Record Forms (retain in case of damage during shipping, discard
after they are recorded by EPA) and then add the completed forms to a zipper storage
bag. Place the bag on top of the cooler contents and then seal the cooler.

3.	Ship the packed cooler to the EPA laboratory using next day air UPS or similar
overnight delivery service. EPA generally will prepare and provide a return shipping
label. If applicable, address the shipment to:

4. Immediately notify Karen Oliver (oliver.karen@epa.gov) of the incoming shipment
via email. Include the shipment tracking number.

9.0 Possible Corrective Actions for Observed Problems During Sampling

9.1	Pump Failure

•	If a pump fails, correct any obvious errors such as kinked lines, battery not fully charged,
etc. If possible, replace the pump.

•	If a replacement pump is unavailable, stop data collection immediately and contact the
NERL/EMMD supervising scientist. Examples of pump failure include: failure to reach
desired flow rate; or failure to maintain the desired flow rate.

•	Document any pump failures in the Data Collection and COC Record Form.

9.2	Possible Contamination of Filters or Supplies

Contact the NERL/EMMD staff scientists for possible replacement items or directions for
decontamination. Be sure to document any suspicion of possible contamination of filters
or supplies in the Data Collection and COC Record Form.

10.0 Recordkeeping

10.1	Data Sheets

All information concerning sample collection will be recorded by the appropriate operator
on the VOC Data Collection and COC Record Form and on the Field Sampling Location
Record Form (see SOP D-SED-IEMB-005-SOP-01). Examples are attached in Appendices
A and C, respectively.

10.2	Calculations

The sample flow rate is directly measured using the average of the pre- and post-sampling
Mesa Labs flow calibrator measurements. The elapsed time in minutes is the sum total of
minutes the pump operated during the sampling episode. A normal 3-hour run period
should have approximately 180 minutes.

Collected air volume is calculated as follows:

1000

Where,	V = Sample volume in liters

T = Elapsed time in minutes
F = Average flow in mL/min

10.3 Chain-of-Custody

The original Data Collection and COC Record Form will accompany the filter samples

1.0 Scope and Application

This standard operating procedure (SOP) describes sample handling techniques for Carbopack X
Radiello Samplers that are used for diffusive sample collection of volatile organic compounds
(VOCs) in ambient air for Tire Crumb Exposure Studies. Direction is provided for field deployment
and shipping.

2.0 Summary of Method

Ambient and personal air samples are collected using Radiello radial diffusive samplers containing
Carbopack X sorbent. Prior to sampling, the Radiello stainless steel mesh cartridges containing
Carbopack X are conditioned according to D-EMMD-AQB-008-SOP-01, "Standard Operating
Procedure for Carbopack X Sorbent Tube Conditioning Using the Markes International Model TC-
20 Sample Tube Conditioner" by placing each Radiello cartridge into an empty industry standard
PerkinElmer-style stainless steel thermal desorption (TD) tube. Conditioned tubes are sealed with
0.25-in. Swagelok caps with combined polytetrafluoroethylene (PTFE) ferrules and are stored in
glass culture tubes with Teflon-lined caps in a refrigerator until needed. The culture tubes are then
placed in protective sleeves in a metal can and stored in a refrigerator until the time ofshipment.

(Note: TD tubes containing Radiello cartridges are visually denoted by one of the two end caps
having a stainless steel nut substituted for a brass nut to differentiate the tubes containing
Radiello cartridges from standard TD tubes that have all brass caps and nuts.)

In the field, the Radiello cartridges are removed from the TD tubes, placed in polypropylene
diffusive bodies and deployed for sampling for a designated time period. The samplers are then
retrieved and prepared for return shipment to the analytical laboratory where they are analyzed
according to either D-EMMD-AQB-006-SOP-01, "Standard Operating Procedure for Desorbing
Volatile Organic Compounds from Carbopack X Sorbent Tubes Using the PerkinElmer
TurboMatrix ATD.' or D-EMMD-AQB-014-SOP-01, "Standard Operating Procedure for
Desorbing Volatile Organic Compounds from Carbopack X Sorbent Tubes Using the PerkinElmer
TurboMatrix ATD 650" and D-EMMD-AQB-003-SOP-01, "Standard Operating Procedure for
Determination of Volatile Organic Compounds Desorbed from Carbopack X Diffusive Sampling
Tubes Using the Agilent 6890N/5975 GC-MSD.'

5.0 Cautions/Interferences

5.1	The operator should handle the TD tubes and Radiello yellow diffusive bodies only while
wearing clean nitrile or cloth gloves so that the tubes do not become contaminated with
body oils, hand lotions, perfumes, etc.

5.2	To maintain sample integrity, labels should not be attached to the TD tubes or Radiello bodies
and ink markings should not be made on the TD tubes or Radiello bodies (see section 9.4).

5.3	Only combined (one-piece) PTFE ferrules should be used with the 0.25-in. storage end
caps as other types of ferrules might not seal adequately or might score the tube.

5.4	A CapLok tool should be used to tighten the fittings one-eighth to one-quarter turn past
finger tight so that they are neither too tight nor too loose.

5.5	Care must be taken when transferring the Radiello Carbopack X cartridge from the TD
tube to the Radiello diffusion body. The cartridge must be gently pushed out of the TD
tube using the supplied "push rod" so as not to damage the wire screen containing the
sorbent. Care must also be taken when transferring the cartridge back into the TDtube.

5.6	Sorbent material can sometimes leak from the Radiello Carbopack X cartridge, most likely
due to a damaged cartridge or improper handling. Laboratory and field personnel should
watch for any significant loss of sorbent material when end caps are changed. Any suspect
tube should be removed from the sampling/analysis queue.

5.7	Since the Radiello Carbopack X cartridge itself does not have a unique identifier, it is
important that each tube be returned to its assigned uniquely identified TD tube when
transferred from the diffusion body back to a TD tube.

5.8	The tubes should be shipped in an airtight, non-VOC-emitting container to minimize their
exposure to possible contaminants in the ambient air.

5.9	The refrigerator in which the tubes are stored should be free of solvents and chemicals to
prevent possible contamination of the tube samples.

5.10	The laboratory in which the tubes are handled should be free of VOCs to prevent possibility
of contamination.

5.11	Depending on the data quality objectives (DQOs) for a particular study, Radiello bodies
and TD tubes may be cleaned after each use to minimize any chance of contamination.

6.0 Personnel Qualifications

Field study personnel should have experience handling TD tubes and collecting trace-level VOC

samples using TD tubes.

7.0 Equipment and Supplies

In general, all sampling equipment and supplies, excluding the VOC-free refrigerator and vacuum

oven, are shipped to sampling sites in packaged field kits prepared by the VOC laboratory. The

following equipment and supplies are needed:

• Refrigerator, VOC free

8.0 Quality Control/Quality Assurance

8.1	Before storing, before and after shipping, and before and after sample collection, the end
caps on the TD tubes should be checked for tightness by tugging simultaneously on each
of the end caps in opposite directions to verify that the tubes are properly sealed.

8.2	TD tubes containing Radiello cartridges are visually denoted by one of the two end caps
having a stainless steel nut substituted in for a brass nut to differentiate the tubes containing
Radiello cartridges from standard TD tubes that have all brass caps and nuts.

8.3	Staff must handle all sampling media with gloves to ensure there is no contamination.

8.4	Staff must inspect Radiello diffusive bodies to ensure they are free of debris prior to
deployment.

9.0 Procedures

9.1 Preparation of TD tubes for outgoing field shipments

1.	Retrieve the conditioned TD tubes and "tug test" tubes as described in section 8.1 to
ensure end caps are secure.

2.	Use paper tape or generated labels on the outside of the appropriate glass vials to
clearly label "Field Spikes," "Field Blanks," and "Spares" (Figure 1). (Refer to the
project-specific Quality Assurance Project Plan (QAPP) to determine how field spikes
and field blanks are prepared and used for the current project.)

Figure 1. Labeled field blank and field spike.

3.	Record the TD tube number of all outgoing tubes in the designated laboratory notebook.

4.	Record the conditioning date next to each outgoing tube and the exposure dates next
to the field spikes.

5.	Make a copy of the laboratory notebook page to be sent to the field (Figure 2).

Packaging TD Tubes for Shipment to or from the Field

Note: Prior to the first use wash all metal shipping cans with soap and deionized (DI)
water. Wipe them down with Tech Wipes and let them air dry.

1.	Insert a short piece of 0.25-in. FEP Teflon tubing as a protective chip in the bottom of a
glass vial to prevent the TD tube from bouncing around and possibly breaking the glass.
Perform the tug test (see section 8.1), and then place the sealed TD tube into the glass vial.

2.	Use forceps or tweezers to insert two 5.5-in. pieces of 0.25-in. o.d. FEP Teflon tubing
strips into the glass vial beside the TD tube one at a time to prevent the TD tube from
bumping the sides of the glass vial and cracking or breaking the glass (Figure 3).

Figure 3. Protective Teflon tubing inserted into glass vial.

3.	Screw the cap, which is fitted with a septum and Teflon liner, onto the glass vial.

4.	Attach a sample ID label to the glass vial and to the field data sheet; this step
streamlines the sample deployment process for the field operators.

5.	Line the bottom of a metal can with a 6-in.-diameter foam disk, and then insert 19
cardboard protective sleeves (1.021-in. i.d. by 5.75-in. length) to cushion the glass vials.

6.	Place the glass vial(s) into the metal can inside the protective sleeves, and insert a piece
of loam cut roughly the size of a cardboard sleeve into the metal can to ensure that the
protection sleeves fit snugly inside the can, as shown in Figure 4. (Note: The seven
protection sleeves in the center are preassembled with bubble wrap and bound together
with cable ties, which allows for easy insertion or removal of the outer band of tubes,
as shown in Figure 5.)

7. Place two pieces of round foam (6.5-in. and 6-in. diameter) in the top of the metal can
and seal the metal can with the lid (Figure 6).

Figure 6. Foam inserts in shipping canister.

8. Store the metal can in a refrigerator at 4 °C until the tubes are to be sent to the field for

sample collection or back to the laboratory for analysis.

9.	Ensure that any tubes that were removed from the metal canisters are repackaged as
described in Section 9.2 steps 1-2 and that all procedures in section 9.2 for packing and
sealing the metal cans are followed.

10.	Pack the diffusive bodies in a zipper storage bag and place it inside a metal shipping
canister.

13. Place the metal cans in coolers (three cans per cooler) fitted with foam packaging, as
shown in Figure 7

Figure 7. Metal cans packed in cooler for shipment.

12. Pack field data sheets and COC forms, spare preprinted sample ID labels, and return
shipping labels inside a large (16 in. m 16 in.) zipper storage bag and place inside the
cooler before shipping. Be sure to sign and date the COC form prior to shipping the
cooler to the field.

Cleaning and Preparing Diffusive Bodies for Shipment to the Field

Laboratory personnel should inspect diffusive bodies for overall integrity prior to each
return shipment to the field and should clean them as necessary using the following
procedure. Compromised diffusive bodies should be discarded by VOC laboratory staff.
When handling diffusive bodies, both field and laboratory personnel must wear cotton or
nitrile gloves at all times to ensure the caps are not contaminated with body oils. Use the
following procedure to clean the diffusive bodies:

1.	Immerse the diffusive bodies in a beaker with mild laboratory detergent and DI water
and sonicate for 20 minutes. (Note: Be sure the diffusive bodies remain submerged by
weighting down with a smaller beaker.)

2.	Rinse the diffusive bodies with plenty of tap water followed with DI water.

3.	Lay diffusive bodies on several layers of laboratory tissues and air dry. Store the clean
diffusion bodies in clean zipper storage bags.


-------

Receiving Sample Media

(Note: Steps 1-10 are "check-in" steps that may be completed in an office or laboratory

upon receipt of sampling media to ensure the integrity of the media and provide time for

organization prior to deployment to the field. Alternatively, these steps may be completed

in the field immediately prior to deployment.)

1.	Remove the shipping canisters from the cooler.

2.	Unpack the glass vials containing the tubes from the shipping canister by opening the
lid of the can with a flathead screwdriver or paint can opener.

3.	Remove the foam pieces from the top of the can, and remove the bound inner unit of
tubes from the can.

4.	Check in the TD tubes one by one by verifying that the glass vials are not cracked and
that the caps are on the glass vials. Verify that the storage end caps are still in place on
the TD tube and then check the TD tube numbers against the COC form. If any of the
TD tubes have end caps that have slipped off or if the glass vials are broken, the
operator should select a different tube for field deployment.

5.	While wearing clean nitrile or cloth gloves, uncap the glass vial and remove the two
Teflon tubing strips using tweezers, forceps, or small pliers one strip at a time so as not
to crack or break the glass vial (Figure 8). Remove the cap from the glass vial and inspect
the inside of the cap to ensure the cap septa and liner are in place. Replace if necessary.

Figure 8. Removing TD tube from the glass vial.


-------
Radiello Samplers Field Deployment
D-EMMD-AQB-019-SOP-01
August 23, 2017
Page 12 of 33

6.	Remove the TD tube from the vial and perform the tug test to ensure the storage end caps
are not loose (Section 8.0). If a problem is noted, choose a different TD tube for field
deployment. Return the tube to the glass vial being sure that the protective Teflon chip is
still on the bottom of the vial. (Note. Since the glass vials provide secondary containment,
if a situation arises where all of the spare diffusive sampling tubes are used, then a tube can
be selected for which the glass vial was broken or cracked. All relevant information on tube
selection must be recorded on the field monitoring data sheet should this situation arise.)

7.	Slide the Teflon strips into the glass vial, cap the vial, and place the glass vial holders in
the shipping can. Repeat these steps for each TD tube that has been received and then
place the foam pieces and lid on the can and seal. (Note. If these check in steps are being
performed in the field at the time of deployment, the operator will not be placing the
tubes or associated Teflon pieces back in the glass vials and metal shipping containers.)

8.	Inspect all Radiello yellow diffusive bodies prior to use. Do not deploy any Radiello
yellow diffusive bodies that have holes in them or have debris on the surface. Spare
Radiello yellow diffusive bodies are provided in every shipment and should be used in
these instances. Compromised Radiello yellow diffusive bodies should be returned by
field staff to the VOC laboratory along with notes detailing concerns or problems
regarding suspect Radiello yellow diffusive bodies. (Note. Cloth or nitrile gloves are
to be worn for all activities involving handling of the diffusive body and/or TD tube
and Radiello cartridge.)

9.	Store the container(s) of TD tubes, tools, spare supplies, pens, diffusion caps, and a
notebook containing the field data sheets in a storage box that can be transported easily
to the field site.

10.	List any observations regarding condition of sample media upon receipt on the field
monitoring data and COC sheet (Appendix B) that accompanied the tube shipment.

11.	If the tubes have been stored in a refrigerator, allow them to come to room temperature
(~ 30 min to 1 h) before using them for sample collection.

Deployment of Radiello Diffusive Samplers

1. Assembly of the sampler for fixed site monitoring requires a tripod sampling stand
(Figure 9A), a triangular support plate that has been modified to fit the tripod, a yellow
diffusive body, a 1/8-inch diameter push rod, and a Radiello Carbopack X cartridge
contained within the TD tube (Figure 9B).

4.	Record the TD tube number(s) of the field blank(s) and field spike(s) on the field data
sheet. For QA samples, place one of the preprinted sample ID labels on the field data
sheet and the other on the glass vial. Field blanks and field spikes must remain sealed
with the storage end caps and are deployed alongside field samples.

5.	To deploy field samples, using the CapLok tool, remove the end caps from both ends
of the TD tube (Figure 12).

Figure 12. Remove end caps with Caplok tools.

6. Insert the 1/8-inch push rod in the grooved end of the TD tube and carefully push the
Radiello Carbopack X cartridge out of the TD tube (A) and into the opening of yellow
diffusive body (B) (See Figure 13). (Note: A correctly centered cartridge should not

13.	Unscrew the yellow diffusive body from the triangular support plate.

14.	Retrieve the exposed Radiello cartridge from the diffusive body using a pair of
stainless steel forceps (Figure 17A). Carefully place the end of the Radiello cartridge
into the non-grooved end of the TD tube and use the 1/8-inch push rod to gently push
the cartridge completely into the TD tube (Figure 17B). (Note: Be sure the Radiello
cartridge is returned to its original TD tube. TD tube numbers must be verified against
the information recorded on the field data monitoring form).

16.	Return glass vials containing TD tubes back to the shipping canister. Place used
Radiello diffusive bodies in a bag marked "Used" and return with samples for
assessment for reuse.

17.	Record tube numbers for any spare or unused tubes. In the comments section of the field
data sheet indicate if the tube was a spare and/or was unused (Figure 16). Ensure that
all entries on the field monitoring sheet are filled on correctly with start times, dates and
sampling notes as well as stop dates, times and sampling notes. (Note: All tubes shipped
from the field must be documented on the field data sheet by field staff.).

18.	Prepare the tubes for return shipment to the laboratory according to the procedure
outlined in section 9.2. Field staff can also refer to the "Field Procedure for Diffusive
Sample Collection Using Radiello Samplers - Deployment and Shipping" in
Appendix C. A laminated version of this procedure will be shipped to field sites at the
start of a study.

10.0 Data and Records Management

10.1	Details of the tube deployment (start/stop times, date, sample ID code, TD tube serial
number, and operator's name) are listed on the field deployment data sheet (AppendixB).

10.2	Data sheets are returned to the laboratory with samples for analysis where they are placed
in designated three-ring binders.

10.3	For large studies, field staff might be asked to populate electronic versions of field data
sheets and send them to the laboratory manager.

10.4	Information from the field data sheets is combined with the corresponding analytical data
in either Excel format or by a data manager as appropriate to a particular study and outlined
in that study's QAPP.

10.5	Laboratory staff should refer to the Field Packing Checklist (Appendix D) and the
Incoming Field Sample Checklist (Appendix E) when preparing outgoing field shipments
and checking in incoming field samples.

Appendix C: Field Procedure for Diffusive Sample Collection Using Radiello
Samplers - Deployment and Return Shipping

Health and Safety Warnings

Glass vials containing TD tubes might occasionally break during shipment. Exercise caution when

packing and unpacking the glass vials from the shipping containers.

Cautions/Interferences

•	The operator should handle the TD and diffusive bodies only while wearing clean cloth or
nitrile gloves.

•	Labels should not be attached to the TD tubes or Radiello diffusive bodies, and ink
markings should not be made on the TD tubes or Radiello diffusive bodies. Markers should
not be used around the TD tubes or Radiello diffusive bodies.

•	Radiello cartridges must be seated properly in the diffusive body. They should not stick
out of the diffusive body by even a millimeter. Any protrusion from the diffusive body
indicates the Radiello sampling cartridge is not properly seated.

•	When sampling is complete, a CapLok tool should be used to tighten the storage end caps
one-eighth to one-quarter turn past finger tight so that they are neither too tight nor too
loose. A tug test should be performed to ensure adequate end cap tightness.

•	The laboratory/area in which the samples are stored and handled should be free of VOCs
to prevent any possibility of contamination.

Procedure

1. Diffusive Sample Collection

Note: Steps 1 through 5 are usually performed in the lab/office upon receipt of the

sampling media to facilitate organization of the field deployment of the TD tubes. Steps

6 through 15 are performed in the field.

1.	Unpack the TD tubes from the shipping can by opening the lid of the can with a screwdriver
as necessary, remove the foam pieces from the top of the can, remove the inner tube
holder of glass vials from the can, and remove the remaining glass vials from the shipping
can if applicable.

2.	Check in the TD tubes one by one by verifying that the glass vials are not cracked and
that the caps are on the glass vials. Verify that the storage end caps are still in place on
the TD tube. If any of the TD tubes have storage end caps that have slipped off or if the
glass vials are broken, the operator should select a different tube for field deployment.

3.	Check the TD labels against the labels on the field data sheet.

4.	While wearing clean nitrile gloves, uncap the glass vial and remove the two Teflon tubing
strips using tweezers, forceps, or small pliers one strip at a time so as not to crack or break


-------
Radiello Samplers Field Deployment
D-EMMD-AQB-019-SOP-01
August 23, 2017
Page 27 of 33

the glass vial.

5.	Remove the TD tube from the vial and perform the tug test to ensure the storage end caps
are not loose. If a problem is noted, choose a different TD tube for field deployment. Return
the tube to the glass vial being sure that the protective Teflon chip is still on the bottom of
the vial.

6.	Slide the Teflon strips into the glass vial, cap the vial, and place the glass vial holders in
the shipping can. Repeat these steps for each TD tube that has been received and then
place the foam pieces and lid on the can and seal.

7.	Inspect all Radiello yellow diffusive bodies prior to use. Do not deploy any Radiello yellow
diffusive bodies that have holes in them or have debris on the surface. Spare Radiello
yellow diffusive bodies are provided in every shipment and should be used in these
instances. Compromised Radiello yellow diffusive bodies should be returned by field staff
to the VOC laboratory along with notes detailing concerns or problems regarding suspect
Radiello yellow diffusive bodies.

8.	Store the container(s) of TD tubes, tools, spare supplies, pens, diffusion caps, and a
notebook containing the field data sheets in a storage box that can be transported easily
to the field site.

Note: Perform the following steps at the field site beginning immediately prior to

deployment of the Radiello Sampler tubes while wearing clean gloves and working

steadily:

9.	Following the procedures above, allow tubes to warm up for 30 minutes prior to
deployment.

10.	Remove a TD tube from a glass vial and use a CapLok tool to loosen and remove the
storage end cap from the sampling end of the tube. Place the Teflon chip and strips, and
storage end cap (as applicable) back into the glass storage vial and cap the glass vial.

11.	Record the appropriate TD tube number on the field data sheet next to its corresponding
sample ID label. Store the glass vial as appropriate.

12.	Using the 1/8-inch push rod, insert in the grooved end of the TD tube and carefully push
the Radiello Carbopack X cartridge out of the TD tube and into the opening of yellow
diffusive body. (Note. A correctly centered cartridge should not stick out even by half a
millimeter. If it does, the cartridge is not correctly positioned and out of axis).

13.	Attach the Radiello sampler to the person or sampling tripod. During personal sampling,
ensure the sample body is not covered by clothing or hair

14.	Follow steps 8 through 12 for each TD tube to be deployed for sample collection.

15.	Do not uncap the field blanks or field spikes, but instead hang them in place with both of
the storage end caps still sealing the TD tube. Record the TD tube serial number for the
field blank(s) and field control(s) on the field data sheet. (Note. This deployment procedure
will depend on the design of a particular study; some studies might specify that the field
blank(s) and field spike(s) travel to the field and then are returned to the field office for


-------
Radiello Samplers Field Deployment

storage during the sampling period.)

16.	Once all Radiello samplers are positioned, mount the tripod as appropriate at the site.
Record the start time and additional sampling details and/or comments on the field
monitoring data sheet.

Note: Perform the following steps at the field site at the end of the sampling cycle.

17.	At the end of the 3-hour deployment period, record the stop date and time on the field
monitoring data sheet and any additional sampling/field comments.

18.	Retrieve the exposed Radiello cartridge from the diffusive body using a pair of stainless
steel forceps. Carefully place the end of the Radiello cartridge into the non-grooved end
of the TD tube and use the 1/8-inch push rod to gently push the cartridge completely into
the TD tube. (Note. Be sure the Radiello cartridge is returned to its original TD tube. TD
tube numbers and labels must be verified against the information recorded on the field
data monitoring form.)

19.	Use CapLok tools to tighten storage end caps on each end of the TD tube and preform
the "tug test" to ensure end caps are tight.

20.	Place the TD back into the appropriate glass vial. Ensure the Teflon chip and two Teflon
strips are also packed inside of the glass vial to provide stability.

21.	Return glass vials containing TD tubes back to the shipping canister. Place used
Radiello diffusive bodies in a bag marked "Used" and store appropriately for cleaning.

22.	Verify that the field sample ID label and TD tube number on the vial match those recorded
on the field monitoring data sheet. Record the stop time and any additional sample
collection data on the field monitoring data sheet beside the appropriate field ID label/TD
tube serial number.

23.	Return all TD tubes and supplies to the storage box/cooler for return to the field office.

2. Shipment to the Laboratory

1.	To prepare the TD tube shipment to the laboratory, check to see that the Teflon tubing
chip is in the bottom of each glass vial to prevent the TD tube from bouncing around and
possibly breaking the glass.

2.	Use tweezers/forceps to insert two Teflon tubing strips into each glass vial beside the TD
tube to prevent the TD tube from bumping the sides of the glass vial and cracking or
breaking the glass.

3.	Screw the vial cap onto the glass vial after checking the vial cap to be sure that the liner
and septum are in place. Replace with a spare liner or septum if necessary.

4.	Place the glass vial(s) into the metal can(s) loaded with cardboard protection sleeves to
cushion the glass vials. Insert the piece of foam that is cut roughly the size of a cardboard
sleeve into the metal can to ensure that the protection sleeves fit snugly inside the metal
can. Place the center tube holder insert into the middle of the can.


-------
Radiello Samplers Field Deployment
D-EMMD-AQB-019-SOP-01
August 23, 2017
Page 29 of 33

5.	Place the two pieces of round foam in the top of the metal can and seal the metal can with
the lid.

6.	Place the metal cans in the same shipping box or container that they were originally
shipped in and fill the container with bubble wrap or other packaging material to cushion
the contents.

7.	Fill out the COC form and return it along with the field data sheets in this shipment. Note:
Make a photocopy of these documents for retention at the field office prior to shipping.

8.	Seal the box securely for shipment, attach the return shipping label for delivery, and be
sure that the package will not be in transit over a holiday or weekend.

Appendix D: Field Packing Checklist for Laboratory Staff

It is helpful to perform these activities a week or two before the next shipment.

Activity

Performed

Count how many clean TD tubes are in the fridge and ready for deployment. This will give
you an idea of how many batches you might need to analyze this week to free up tubes for
the next shipment.

r

Count how many glass vials and vial caps are currently available for field use.

r

Be sure you have enough coolers.

r

Be sure you have enough tubes for the field spike exposures. It is always a good idea to
ask if there is a need for any additional field spikes outside the norm before starting the
field spike exposures.

r

Check to see if you have enough hang tag packets for shipping the coolers. The sooner
you know the better in case more need to be ordered.

r

Be sure you have enough protective Teflon strips and chips to pack into each vial. You
might need to check incoming shipments stored in the fridge for extra Teflon strips/chips if
you do not have enough for outgoing shipments.

r

Before you start packing, check to see if any additional sites have been added or if sites
have been removed for each field location. It is also helpful to pass this information along
to the staff member who is preparing the sample ID labels.

r

Be sure you have enough clean Radiello diffusive bodies. Write down how many you pack
per shipment and ensure they are clean.

r

Always write down the TD tubes numbers packed in each batch in the designated lab
notebook. Include the exposure date for field spikes and lab controls and the conditioning
dates for all other tubes packed.

r

QA packed shipments and any inventory forms that are shipped to ensure tube numbers
are typed correctly. Templates for inventory sheets are on the desktop of the spare
computer in D260 in the folder labeled "Packing Lists".

r

Always pack field spikes and field blanks in vials labeled with paper tape: "Field Spike,"
"Field Blank," or "Spare."

r

Store outgoing shipments on the top shelf on the right-hand side of the refrigerator.

r

Copy outgoing COC signature pages and tube inventory lists and store in designated field
study COC binders.

r

Store all emails/correspondence relevant to a particular batch with copies of the COC.

Appendix E: Incoming Field Sample Checklist for Laboratory Staff

Activity

Performed

Be sure all check-in notes, signatures, and date are recorded on the original COC in
permanent waterproof black pen.

r

Sign and date the signature page of the COC as well as the boxes next to each received
sample.

r

If any additional tubes are received that are not listed on the COC by field operators,
record those tube numbers on the COC and initial/date receipt of those tubes as well.

r

In general, one unused/unexposed tube is sent back with each shipment. This tube is
considered the shipping blank* Write "shipping blank" in the "Receipt Comments"
section and assign the appropriate Sample ID to this tube on the COC in the box where the
sample ID label is placed according to the format designated in the associated QAPP.
Examples of recently used Sample ID number formats for shipping blanks are shown
below:

For Reaional Shiooina Blank/Spare Tube

Region-Site-Week-Type

##-99-##-SB

Example: 06-99-12-SB

Region 6, Site 99, Week 12, Shipping Blank

Note: The designated site for the shipping blank sample is 99.

The newly assigned sample ID should also be written on paper tape and placed on

the vial that the tube is stored in.

For Phillv Shiooina Blank/Spare Tube

Site-Week-Type-PHL

99-##-SB-PHL

Example: 99-25-SB-PHL

Site 99, Week 25, Shipping Blank, Philly

Note: The designated site for the shipping blank sample is 99.

The newly assigned sample ID should also be written on paper tape and placed on

the vial that the tube is stored in.

Label the glass vial with the shipping blank sample code before storing.

*lf multiple spare/unused TD tubes are shipped back, select only one as the shipping blank
and assign an appropriate Sample ID. The remaining unused tubes should be conditioned
prior to reuse.

r

Cross-check TD tube numbers and Sample IDs on the tubes against those on the COC.

r

Note any observations in the "Receipt Comments" section. The following are some
suggestions of the info to enter so that everyone checking in samples is making the same
types of check-in comments, which helps when flagging data in the database.

•	"SE loose" - the sampling end cap on the grooved end of the tube is loose;
tightened

•	"RE loose" - the rear end cap is loose; tightened

•	"Vial cracked"

•	"Cap off vial"

•	"SE end cap off'/ "SE end cap nut off'

•	"RE end cap off/ "RE end cap nut off

•	"Tube dirty"

•	"SE ferrule missing/RE ferrule missing"

•	"Tube number incorrect"; "Correct tube number is

•	"Sample ID is incorrect"; "Correct sample ID is...."

•	"Tubes switched in vial; switched tubes to match COC"

•	"Tube invalid no analysis"



Remove all protective Teflon tubing strips and chips to ensure they are available for the
next outgoing shipments. If any strips or chips are dirty, they can be wiped off with lint-free
Kimwipes, and in extreme cases can be rinsed with Dl water and dried with house air.
Never use solvents.

r

Remove white lined vial caps/black lined vial caps and replace them with white vial caps
that are not shipment-ready before they are stored.

r

Set all tubes to the side that are considered invalid and will not be analyzed. These are
usually tubes that are found on the ground. Inform the VOC lab manager of these tubes
and verify that they will not be analyzed.

r

Store all checked-in tubes inside their glass vials, place them in a cardboard box, and
place them in the fridge. Labels from the incoming canisters can be placed on the
cardboard box to identify the samples in the box.

r

Clean any used Radiello diffusive bodies. Discard those that are torn or unfit for additional
use.

r

Immerse the diffusive bodies in a beaker with mild laboratory detergent and Dl water and
sonicate for 20 minutes. Note: Be sure the diffusive bodies remain submerged by
weighting down with a smaller beaker.

r

Rinse the diffusive bodies with plenty of tap water followed with Dl water. Lay diffusive
bodies on several layers of laboratory tissues and air dry. Store the clean diffusion bodies
in clean zipper storage bags.

r

Copy the COC after check-in is complete and place the original COC in the designated
binder with any correspondence regarding that particular batch. Place the copy aside in the
designated space so that the Excel tube tracking sheet can be updated. In addition, store a
copy of the COC with the tubes that are refrigerated for future analysis.

r

Acknowledge receipt of all incoming shipments for the day and any important
notes/findings in the designated laboratory notebook.

1.0 SCOPE AND APPLICATION

This standard operating procedure (SOP) describes the method for collecting wipe samples from
synthetic turf field surfaces to measure semivolatile organic compounds (SVOCs) and metals for the
United States Environmental Protection Agency (EPA) exposure characterization pilot tire crumb
rubber research study (TCRS).

2.0 SUMMARY OF THE METHOD

Dermal, inhalation, and ingestion of dust at synthetic turf fields may represent important pathways of
exposure to chemicals associated with tire crumb rubber, other synthetic field materials, and
environmental dust deposited on the field. The concentrations of metals and semivolatile organic
compounds (SVOCs) on field surfaces available for dermal transfer must be measured to determine
human exposures and to compare these to the various exposure pathways and to biologic markers in
blood and urine.

Surface wipe samples for metals analysis will be collected at synthetic turf field sites using a wet
(water) wipe (Environmental Express, Ghost Wipe No. 4210) conforming to American Society for
Testing and Materials (ASTM) E1792 (ASTM-03, 2016a) requirements. Surface wipe samples for
SVOC analysis will be collected using cleanroom twill wipes (M.G. Chemicals, cotton, pre-cleaned),
using a dry 30.5 cm x 30.5 cm wipe attached to a drag sled and a wipe wetted with 1:1 isopropyl
alcohol:water with dimensions of 4 inch x 4 inch (10 cm x 10 cm).

4.0	CAUTIONS

4.1	Nitrile gloves and eye protection should be worn during sample collection for metals wipe samples.
Silver Shield gloves and eye protection should be worn during sample collection for SVOCs.

4.2	Field staff should keep the sampling materials and the samples out of the reach of children.

4.3	Do not wipe the template demarcating a sampling area.

4.4	Collect samples at times when it was safe to do so with regard to any activities occurring on the
field. Sample collection time is not critical for these samples, but the samples should be collected at a
convenient time during the overall exposure measurement activities at each field.

4.5	No photography will be performed of any activities at the fields.

5.0	RESPONSIBILITIES

5.1	The EPA project staff will prepare the surface wipe sample collection equipment and materials and
deliver them to the field coordinator. EPA will provide the spiked field controls.

5.2	The field coordinator will receive the surface wipe sample collection equipment and materials. The
field coordinator will create a strategy and schedule to deploy or collect the appropriate percentage of
each type of field quality control (QC) samples as defined in the QAPP addendum. The field
coordinator will communicate the schedule for QC samples to the field staff and distribute any
additional QC sample materials. The field coordinator will distribute surface wipe sample collection
equipment and materials to the field staff. Upon collection of the surface wipe samples, the field
coordinator will be responsible for returning the samples with their collection records and Chain-of-
custody (COC) sheets to the EPA in Research Triangle Park (RTP), NC for analysis.

5.3	The field staff will be responsible for obtaining the collection equipment and materials from the
field coordinator, collection of the surface wipe sample, entering relevant information on the sample
collection record sheets, and returning collected surface wipe samples and records to the field
coordinator.

7.0	PROCEDURES

7.1	SAMPLE COLLECTION

Wipe samples will be collected from synthetic turf fields to support characterization of chemical
constituents.

7.1.1 Identification of Field Sampling Location

Individual wipe and drag sled samples will be collected from three locations at each field (see Figure
1). A separate set of samples will be collected at each location including: one wipe sample for SVOC
analysis, one wipe sample for metals analysis, and one drag sled sample for SVOC analysis. It is
important that the surface SVOC, surface metals, and drag sled SVOC not be collected from the exact
same spots on the field. They should be collected in proximity to each other at the three locations but
their sampling areas must not overlap (Figure 1).

7.1.2 Gloves

Prior to collecting metals surface wipe samples, put on clean, powderless nitrile gloves and keep them
on during the entire sampling period. Prior to collecting surface wipe SVOC and drag sled SVOC
samples, put on Silver Shield gloves.

7.2 Field Surface Wipes for Metals

Samples will be collected at positions #1, #2, and #5 as shown in Figure 1, for a total of three separate
samples. No background sampling location wipe sample will be collected.

Use surface wipes to collect samples for metals analysis at synthetic turf field sites. Samples are
collected with a wet (water) wipe material conforming to ASTM E1792 (ASTM-03, 2016a)
requirements (Ghost Wipe No. 4210, Environmental Express).


-------
D-SED-IEMB-026-SOP-01
Date: 8/21/2017
Page: 7 of 22

Collect samples following the ASTM El 728 sample collection method (ASTM 1728-16, 2016b), a
standard wet-wipe method for collecting dust from indoor floor surfaces that use water as the wetting
agent. Specifically, a 929 cm2 (1-ft2) template is placed on the surface of the field.

Remove the wet wipe from the foil packet. Using one side of the wipe, wipe the turf surface in a S or
Z-shaped pattern within the template area. After folding the wipe in half to get a fresh wipe surface,
wipe the area again in a S or Z-shaped pattern perpendicular to the first wipe pattern (see Figure 2).
Next, fold the wipe in half again and wipe the edges of the sampling area near the interior portion of
the template. Prior to placing the wipe in a storage tube, use plastic forceps to remove full size tire
crumb rubber infill granules, synthetic grass blades, and other large debris or litter. Finally, fold the
wipe and place it a pre-cleaned 50-mL polyethylene tube (Environmental Express, Disposable
Digestion Cup No. SC475 or equivalent) for storage. Tightly cap the tube and transport at ambient
temperature or lower to the laboratory, where the samples are placed in a freezer at -20 °C.

Figure 2. Wiping the turf surface in a S or Z-shaped pattern within the 929 cm2 template area.
7.3 Field Surface Wipe Samples for SVOCs

Ensure that you have a sufficient number of previously pre-cleaned SVOC wipes for the field team
staff for transport to the field location.

Two types of field surface wipe samples will be collected for SVOCs analysis. One method uses a dry
wipe material attached to a drag sled. The second uses an isopropanol:water-wetted wipe.

7.3.1 Drag Sled Dry Wipe Method: Collect surface wipe drag sled samples for SVOC analysis at
synthetic turf field sites using a dry wipe material (Texwipe TX312 Cleanroom Twill, 30.5 cm x 30.5
cm, cotton) that has been cleaned by pre-extraction using a series of solvents including acetone and
hexane prior to use.

Collect samples only at times when it was safe to do so with regard to any activities occurring on the
field. Sample collection time is not critical for these samples, but the samples should be collected at a


-------
D-SED-IEMB-026-SOP-01
Date: 8/21/2017
Page: 8 of 22

convenient time during the overall exposure measurement activities at each field.

Collect samples at positions #1, #2, and #5 as shown in Figure 1, for a total of three separate samples.
Samples will be collected from different areas than the areas used for metals wipe sample collection.
Ensuring that there is no area overlap can be accomplished by placing templates and marking the drag
sled area prior to sampling. No background sampling location wipe samples will be collected.

Using clean, Silver Shield gloves, remove the wipe material from its storage container and clamp it to
a wipe sampling push sledge device (see Figure 3). The device has a 10 kg aluminum block of the
dimensions 25.4 x 25.4 x 5.1 cm with clamps on one side for securing the wipe material and an
attached handle for pushing the devi ce. Secure the wipe materi al so that the 645 cm2 bottom face of the
block is completely covered by the wipe material.

Using a tape measure, mark a 5 m x 1 m area (5 m2) on the synthetic turf field. The area may be
marked with masking tape or surveyor flags; existing field lines may also be used to denote one or
more area boundaries. With the wipe sampler starting in one corner of the marked area, drag the sled
down the 5-m length and then back again. Move the drag sled one width over in the collection area.
Drag the sled down the 5-m length and then back again. Repeat this until the entire 5 m2 has been
wiped with one up and one back pass. When pushing or pulling the drag sled, keep the handle at or
below waist level to minimize the vertical force of the handle on the drag sled body - the goal is to
achieve consistency by having the majority of the force resulting from the weight of the drag sled
body.

Prior to placing the wipe back into the storage container, remove as much as possible of any synthetic
grass blades, large tire crumb rubber pellets, and other large debris or litter on the sides of the wipe
material that did not contact the field. With forceps, remove any large (> 1 mm) tire crumb rubber
pellets from the portion of the wipe material that contacted the synthetic turf field. Do not attempt to
rem ove any grass blades from the field-facing side of the filter.

Finally, fold the wipe and place it in the clean 500 mL amber glass wide mouth storage bottle with
Teflon cap liner. Tightly cap the bottle and transport at 4 °C or lower to the laboratory, where the
samples are placed in a freezer at -20 °C.

7.3.2 Wetted Wipe Method: Collect wetted samples at synthetic turf field sites using a wipe material
(Texwipe TX312 Cleanroom Twill, 10 cm * 10 cm, cotton) that has been cleaned by pre-extraction


-------

using a series of solvents including acetone and hexane prior to use. In the laboratory, prior to
shipment to the field site, each wipe will be placed in a clean 60-mL wide-mouth amber jar, and 3 mL
of 1:1 isopropanol:water will be added directly to the wipe material in the j ar, dispersed across the
folded wipe material as evenly as possible. The jar will then be tightly capped with Teflon-lined lids.
Sample labels will be affixed to the jars, and the jars will be transported to the field site.

Collect samples at times when it was safe to do so with regard to any activities occurring on the field.
Sample collection time is not critical for these samples, but the samples should be collected at a
convenient time during the overall exposure measurement activities at each field.

Collect samples at posi tions #1, #2, and#5 as shown in Figure 1, for a total of three separate samples.
Collect samples from different areas than the areas used for previous wipe sample collection. Ensuring
that there is no area overlap can be accomplished by placing templates and marking the drag sled area
prior to sampling. No background sampling location wipe samples will be collected.

Place a 929 cm2 (1 ft2) aluminum template on the surface of the field.

Using clean, Silver Shield gloves and, if needed, clean tweezers, remove the pre-wetted wipe material
from its storage container. Using one side of the wipe, wipe the turf surface in a S or Z-shaped pattern
within the template area (see Figure 4). After folding the wipe in half to get a fresh wipe surface, wipe
the area again in a S or Z-shaped pattern perpendicular to the first wipe pattern. Next, fold the wipe in
half again and wipe the edges near the interior portion of the template. Prior to placing the wipe back
into its sample jar, use forceps to remove full size tire crumb rubber infill granules (>1 mm), synthetic
grass blades, and other large debris or litter. Finally, fold the wipe and place it back into its 60-mL
amber wide-mouth glass jar. Tightly cap the jar and transport at 4 °C or lower to the laboratory, where
the samples are placed in a freezer at -20 °C.

8.0 RECORDS

A data collection system will be used to capture information associated with the collection of all
samples. For the surface wipe samples, the sample collection information to be recorded will include
the following, as a minimum: the sample ID, the date and time of the sample collection, the sampling
location, initials or ID number of the field staff member responsible for the sample collection, and any
comments regarding collection (Appendix A). Other information shall be collected as needed to ensure
successful collection and interpretation of data. Please see D-SED-IEMB-030-SOP-01 for recording
sample collection locations on the proper field diagram.

Section B3 in the QAPP addendum details the sample code information. Sample codes used for the
EPA Tire Crumb Rubber Research Study will follow the general naming scheme used by the EPA for
the tire crumb rubber characterization study.

9.0	QUALITY CONTROL AND QUALITY ASSURANCE

9.1	Field blank (FB) and field control spikes (FC) samples will be prepared and used according to the
schedule outlined in the QAPP addendum Table B-3. For storage, shipping, analysis and quantitation
procedures, FB and FC samples will be prepared and treated in the same manner as the wipe samples.

9.2	FB will be deployed to monitor background contamination during storage and analysis. FB samples
will be prepared by opening the container with wipe while wearing Silver Shield (drag sled and wet
SVOC wipes) or nitrile (metals wipes) gloves, unfolding, folding, and placing into a labeled sample
container. FB samples shall otherwise be treated in the same manner as the surface wipe samples.

9.3	FC will be deployed to assess recovery of target analytes from the wipe medium under the same
storage and transportation conditions as the field samples. FC will be prepared by adding known


-------

Page: 12 of 22

amounts of target compounds to matrix blanks which is stored in a sealed container. The container is
shipped to the field and returned without opening/handling. It is stored under the same conditions as
field collected samples.

9.4	At least one FB and FC should be included with each batch of wipe samples shipped to the EPA
laboratory.

9.5	A duplicate sample will be collected for each of the three sample types at each field. Duplicates
will be collected from a previously unsampled field area directly adjacent to its matching sample, using
all of the same procedures that are used for the samples.

1.0 SCOPE AND APPLICATION

This standard operating procedure (SOP) describes the method for collecting dermal wipe samples
from a participant's skin in order to measure semi-volatile organic compounds (SVOCs) and metals on
the skin for the EPA pilot tire crumb rubber research study (TCRS).

2.0 SUMMARY OF THE METHODS

Dermal, inhalation, and ingestion of dust at synthetic turf fields may represent important pathways of
exposure to chemicals associated with tire crumb rubber, other synthetic field materials, and
environmental dust deposited on the field. The concentrations of metals and SVOCs on the skin of
TCRS participants must be measured to determine dermal exposures and to compare these to the other
pathways and to biologic markers in blood and urine.

Each participant's skin will be wiped in the following manner:

Metals: Three dermal wipe samples will be collected for metal analysis from each participant
following an on-field sports activity in the exposure characterization pilot study. One sample will be a
hand wipe sample, the second sample will be from a defined area of the forearm, and the third sample
will be collected from a defined area of the leg (either calf or thigh depending on which area had more
exposed skin area during the sports activity). Wipe samples for metals will be collected from one hand,
one arm, and one leg on the left side of the participant's body.

Semivolatile Organics: Three dermal wipe samples will be collected for SVOC analysis from each
participant following an on-field sports activity in the exposure characterization study. One sample will
be a hand wipe sample, the second sample will be from a defined area of the forearm, and the third
sample will be collected from a defined area of the leg (either calf or thigh depending on which are had
more exposed skin area during the sports activity). Wipe samples for SVOCs will be collected from
one hand, one arm, and one leg on the right side of the participant's body.

4.0	CAUTIONS

4.1	Field staff will keep all sampling materials out of reach of children.

4.2	Standard laboratory protective gloves are required for this procedure to eliminate transfer of
chemicals from the technician's hands onto the wipe media and to provide hygiene for participant
contact. Nitrile gloves should be worn during sample collection for metals wipe samples. Silver Shield
gloves should be worn during sample collection for SVOCs.

5.0	RESPONSIBILITIES

5.1	The EPA project staff will provide wipe media, digestion cups, and glass jars (collection materials)
and deliver them to the field coordinator. EPA will provide the spiked field controls.

5.2	The field coordinator will receive the dermal wipe sample collection equipment and materials. The
field coordinator will create a strategy and schedule to deploy or collect the appropriate percentage of
each type of quality control (QC) samples. The field coordinator will communicate the schedule for
QC samples to the field staff and distribute any additional QC sample materials. The field coordinator
will distribute the collection materials to the field staff. Upon collection of the dermal wipe samples,
the field coordinator will be responsible for returning the samples with their collection records and
COC sheets to the EPA in Research Triangle Park (RTP), NC for analysis.

5.3	The field staff will be responsible for obtaining the collection equipment and materials from the
field coordinator, collection of the dermal wipe samples, entering relevant information on the sample
collection record and COC sheets (Appendix A) and returning collected hand wipe samples to the field
coordinator.

6.0	MATERIALS AND REAGENTS

6.1	Wipe media for SVOCs (M.G. Chemicals, Cleanroom Twill wipes, 10 cm x 10 cm, cotton, pre-
cleaned)

6.2	Wipe media for metals (Environmental Express SC 4210 (or similar) Ghost Wipes, 15 cm x 15 cm,
packaged pre-moistened with deionized water)

6.3	Isopropanol, ACS Reagent Grade

6.16	Rectangular flexible Teflon sheet template with outer dimensions of 11.5 x 19.0 cm and inner
dimensions of 7.5 x 15 cm dimensions to provide a wipe surface area of 112 cm2. Two templates are
needed for each participant, one for metals wipe collections and one for SVOC wipe collections.

(Note: if insufficient templates are available, a single template may be used for both metals and
SVOCs by first cleaning the template with a wetted wipe).

7.0	PROCEDURES

7.1	SAMPLE COLLECTION

Sample collection will follow the procedures for 7.1.1 "metals" collection, followed by the procedures
for 7.1.2 "SVOC" collection.

7.1.1 Collection of dermal wipe samples from participants for metals:

7.1.1.1	Timeline: Dermal wipes will be collected from each person, as soon as possible following
his/her activity on a field.

7.1.1.2	Before starting sample collection, briefly describe the dermal wipe sampling procedures that
will be used to the participant. Ask the participant if it is OK to collect the dermal wipe samples on
their hands, arms, and legs. Make sure there is at least one other adult field team member present
during the sample collection (parents of child participants may also be present if they wish).

7.1.1.3	Prior to collecting metals wipe samples, put on clean, powderless nitrile gloves and keep them
on during the entire sampling period. New gloves should be worn for each participant.

7.1.1.4	For metal analysis, use wet (water) wipe material (Environmental Express, Ghost Wipe No.
4210) conforming to American Society for Testing and Materials (ASTM) El792 requirements
(ASTM-03, 2016a).

7.1.1.5	Hand wipe sample: Remove a wet wipe from the foil packet and unfold it to its full dimensions.
With moderately firm pressure, wipe the left hand, including the back, front, and sides of the hand,
fingers, and thumb. Next, fold the wipe with the exposed (contacted) surface on the inside and place
into a pre-cleaned 50-mL polyethylene tube (Environmental Express, Disposable Digestion Cup No.
SC475 or equivalent) for storage.


-------
SOP: SED-IEMB-02 8-SOP-01
Date: Draft August 21,2017
Page: 6 of 15

7.1.1.6 Forearm wipe sample: Select a clean Teflon template. Place it over the underside of the left
forearm. Use a short piece of bandage tape to tape one short end of the template to the left arm, then a
second short piece of tape to secure the other short end to the arm. The template should lay as flat
against the arm as possible once taped down. Remove a wet wipe ("Ghost Wipe") from the foil packet
and unfold it to its full dimensions. Then, fold it into quarters before beginning sample collection. With
moderately firm pressure, thoroughly wipe the bottom (underside) of the left forearm over the entire
112 cm2 area using a rectangular template. Next, fold the wipe one more time, with the exposed
(contacted) surface now on the inside. With moderately firm pressure, thoroughly wipe the bottom
(underside) of the left forearm over the entire 112 cm2 area for a second time. Again fold the wipe with
the exposed (contacted) surface on the inside and place into a pre-cleaned 50-mL polyethylene tube
(Environmental Express, Disposable Digestion Cup No. SC475 or equivalent) for storage.

7.1.1.7: Leg wipe samples: Select the area to sample based on skin that was most exposed during the
participant activity. The lower leg is preferred, but the lower part of the upper leg may be used if it was
the most exposed area. Use the same Teflon template that was used on the forearm. Place the template
over the outer side of the left leg. Use a short piece of bandage tape to tape one short end of the
template to the leg, then a second short piece of tape to secure the other short end to the leg. The
template should lay as flat against the leg as possible once taped down. Remove a wet wipe ("Ghost
Wipe") from the foil packet and unfold it to its full dimensions. Then, fold it into quarters before
beginning sample collection. With moderately firm pressure, thoroughly wipe the left leg over the
entire 112 cm2 area using a rectangular template. Next, fold the wipe one more time, with the exposed
(contacted) surface now on the inside. With moderately firm pressure, thoroughly wipe the left leg
over the entire 112 cm2 area for a second time. Again fold the wipe with the exposed (contacted)
surface on the inside and place into a pre-cleaned 50-mL polyethylene tube (Environmental Express,
Disposable Digestion Cup No. SC475 or equivalent) for storage.

7.1.1.8	Record the sample collection information on the sample collection sheet (Appendix A).

7.1.1.9	Ensure all caps are tightly fitted and transport tubes at ambient temperature or lower to the
laboratory, where the samples are placed in a freezer at -20 °C

7.1.2 Collection of dermal wipe samples from participants for SVOCs:

7.1.2.1	In the laboratory, prior to shipment of materials to the field site, each wipe will be placed in a
clean 60-mL wide-mouth amber jar, and 3 mL of 1:1 isopropanol: water will be added directly to the
wipe material in the jar, dispersed across the folded wipe material as evenly as possible. The jar will
then be tightly capped with Teflon-lined lids. Sample labels will be affixed to the jars, and the jars will
be transported to the field site.

7.1.2.2	Timeline: Dermal wipes will be collected from each person, as soon as possible following
his/her activity on a field.

7.1.2.3	Prior to collecting wipe samples, put on clean, Silver Shield gloves and keep them on during
the entire sampling period. New gloves should be worn for each participant.

Page: 7 of 15

7.1.2.4	Collect wipe samples for SVOC analysis using wetted (1:1 water:isopropanol) cotton wipe
material (M.G. Chemicals, Cleanroom Twill, 10 x 10 cm).

7.1.2.5	Hand wipe sample: Remove the wipe from its glass storage jar to its full dimensions. With
moderately firm pressure, wipe the right hand, including the back, front, and sides of the hand, fingers,
and thumb. Next, fold the wipe with the exposed (contacted) surface on the inside and replace into its
glass storage jar.

7.1.2.6	Forearm wipe sample: Select a clean Teflon template. Place it over the underside of the right
forearm. Use a short piece of bandage tape to tape one short end of the template to the right arm, then a
second short piece of tape to secure the other short end to the arm. The template should lay as flat
against the arm as possible once taped down. Remove a wipe from its glass storage jar and unfold it to
its full dimensions. Then, fold it into quarters before beginning sample collection. With moderately
firm pressure, thoroughly wipe the bottom (underside) of the right forearm over the entire 112 cm2 area
using a rectangular template. Next, fold the wipe one more time, with the exposed (contacted) surface
now on the inside. With moderately firm pressure, thoroughly wipe the bottom (underside) of the right
forearm over the entire 112 cm2 area for a second time. Again fold the wipe with the exposed
(contacted) surface on the inside and place it back into its labeled storage jar and seal the cap tightly.

7.1.2.7: Leg wipe samples: Select the area to sample based on skin that was most exposed during the
participant activity. The lower leg is preferred, but the lower part of the upper leg may be used if it was
the most exposed area. Use the same Teflon template that was used on the forearm. Place the template
over the outer side of the right leg. Use a short piece of bandage tape to tape one short end of the
template to the leg, then a second short piece of tape to secure the other short end to the leg. The
template should lay as flat against the leg as possible once taped down. Remove a wet wipe from its
glass jar and unfold it to its full dimensions. Then, fold it into quarters before beginning sample
collection. With moderately firm pressure, thoroughly wipe the right leg over the entire 112 cm2 area
using a rectangular template. Next, fold the wipe one more time, with the exposed (contacted) surface
now on the inside. With moderately firm pressure, thoroughly wipe the right leg over the entire 112
cm2 area for a second time. Again fold the wipe with the exposed (contacted) surface on the inside and
place it back into its labeled storage jar and seal the cap tightly.

7.1.2.8	Record the sample collection information on the sample collection sheet (Appendix A).

7.1.2.9	Ensure all caps are tightly fitted onto the glass storage jars and place the jars into a cooler with
frozen ice packs. Samples must be stored on ice packs, or in a refrigerator or freezer following
collection. Samples must be shipped to the laboratory in a cooler with frozen ice packs. Upon receipt
at the laboratory, samples are placed in a freezer at -20 °C

7.2 HANDLING AND PRESERVATION

7.2.1 After collection and during transport from the collection site, store the SVOC wipe samples in a
cooler with ice packs. Wipe samples for metals analysis may remain at ambient temperatures.


-------
SED-IEMB-028-SOP-01

SOP:

Date: Draft August 21,2017
Page: 8 of 15

7.2.2	Store pre-cleaned 50-mL polyethylene tube (Environmental Express, Disposable Digestion Cup
No. SC475 or equivalent) with metals wipe samples at ambient temperature at the field site and during
shipment. (Note: metals wipe samples may be stored and shipped in a cooler at lower than ambient
temperatures if that is most convenient). Wipe samples for SVOC analysis must be stored on ice packs,
or in a refrigerator or freezer following collection, and shipped in a cooler on frozen ice packs to the
laboratory. All tubes and jars must be tightly capped. Samples do not need to be shipped each day, and
may be accumulated across sampling days at a field location prior to shipment. Upon receipt at the
laboratory, wipe samples for SVOC analysis must be placed in a freezer at approximately -20 °C.

7.2.3	Ship samples and their sample collection data/COC sheets to:

US EPA Chemical Services
Kent Thomas or Scott Clifton
109 T.W. Alexander Drive
Building E Loading Dock, Rm E178
Research Triangle ParkNC 27709-0002
Telephoned 19-541-7939

8.0 RECORDS

A data collection system will be used to capture information associated with the collection of all
samples. For the technician collected dermal wipe samples, the sample collection information to be
recorded will include the following, as a minimum: the sample ID, the participant ID, the date and time
of the sample collection, initials or ID number of the field staff member responsible for the sample
collection, and any comments regarding collection (Appendix A). Other information shall be collected
as needed to ensure successful collection and interpretation of data. Section B3 in the QAPP addendum
details the sample code information.

The specific coding information for field wipe samples is extracted from the QAPP addendum:

TCRS-R-YY-W-X-Y-Z

Where:

TCRS

Designates the tire crumb rubber research study

R - Participant identification number

1-8; each number assigned to a unique participant where participant-specific ID is required
(personal air, dermal)

0 for all samples not associated with a specific participant


-------
SOP: SED-IEMB-028-SOP-01
Date: Draft August 21,2017
Page: 9 of 15

VV - Field ID number

Two-digit code unique to each field (We will use a different unique code for each
field/participant group combination. We will not try to match to any previous field numbers so
we can pre-print all labels. Numbers will go from 70 to 79).

W - Sample type designator
F = sample
D = duplicate sample
B = field blank
C = field control (spike)

X - Method type designator

N = personal dermal sample metals
L = personal dermal sample SVOCs

Y - Sample collection location character

H for dermal samples collected from hands
A for dermal samples collected from arms
L for dermal samples collection from legs

Z - Parent/subsample designation character

We will use a value of zero (0) for all parent samples.

We will use the character L to designate laboratory QC samples.

Additional digits may be assigned if any sub-samples are generated.

9.0	QUALITY CONTROL AND QUALITY ASSURANCE

9.1	Field blank (FB) and field control spikes (FC) samples will be prepared and used according the
QAPP addendum Table B-3. For storage, shipping, analysis and quantitation procedures, FB and FC
samples will be prepared and treated in the same manner as the hand wipe samples.

9.2	FB will be deployed to monitor background contamination during storage and analysis. The FB
will consist of clean wipes that are removed from the container while wearing nitrile (metals) or Silver
Shield (SVOCs) and handled and folded in the same manner as the actual dermal wipe samples, with
the exception that no skin or other surface is wiped. They are then returned to their containers and
shipped or driven to the EPA laboratory.

9.3	FC will be deployed to assess recovery of target analytes from the wipe media under the same
storage and transportation conditions as the field samples. FC will be prepared by adding known
amounts of target compounds to wipe media, sealed in a sample container which will remain unopened
in the field and returned to the EPA laboratory.


-------
SOP: SED-IEMB-028-SOP-01
Date: Draft August 21,2017
Page: 10 of 15

9.4	At least one FB and FCS should be included with each batch of hand wipe samples shipped to the
EPA laboratory.

9.5	No duplicate dermal wipe samples will be collected due to the increased participant burden and
time they would add.

1.0 SCOPE AND APPLICATION

This standard operating procedure (SOP) describes the method for collecting dust from synthetic turf
field surfaces to measure semivolatile organic compounds (SVOCs) and metals for the United States
Environmental Protection Agency (EPA) exposure characterization pilot tire crumb rubber research
study (TCRS).

2.0 SUMMARY OF THE METHOD

Dermal, inhalation, and ingestion of dust at synthetic turf fields may represent important pathways of
exposure to chemicals associated with tire crumb rubber, other synthetic field materials, and
environmental dust deposited on the field. The concentrations of metals and SVOCs on field surfaces
available for dermal transfer must be measured to determine human exposures and to compare these to
the various exposure pathways and to biologic markers in blood and urine.

Dust samples for SVOCs and metals analysis will be collected at synthetic turf field sites by on-field
sieving of bulk dust collected as a composite from three locations on the field using a 120 mesh (150
|iM) stainless steel sieves.

convenient time during the overall exposure measurement activities at each field.

4.3 No photography will be performed of any activities at the fields.

5.0	RESPONSIBILITIES

5.1	The EPA project staff will prepare the dust sample collection equipment and materials and deliver
them to the field coordinator. EPA will provide the spiked field controls.

5.2	The field coordinator will receive the dust sample collection equipment and materials. The field
coordinator will create a strategy and schedule to deploy or collect the appropriate percentage of each
type of field dust quality control (QC) samples as defined in the QAPP addendum. The field
coordinator will communicate the schedule for QC samples to the field staff and distribute any
additional QC sample materials. The field coordinator will distribute dust sample collection equipment
and materials to the field staff. Upon collection of the field dust samples, the field coordinator will be
responsible for returning the samples with their sample collection records and Chain-of-custody (COC)
sheets to the EPA in Research Triangle Park (RTP), NC for analysis.

5.3	The field staff will be responsible for obtaining the collection equipment and materials from the
field coordinator, collection of the dust samples, entering relevant information on the sample collection
record sheets and COC, and returning collected dust samples and records to the field coordinator.

6.0	MATERIALS AND REAGENTS

7.0	PROCEDURES

7.1	SAMPLE COLLECTION

Field dust samples will be collected from synthetic turf fields to support characterization of chemical
constituents.

7.1.1 Identification of Field Sampling Location

Samples will be collected across three locations at each field (see Figure 1). Samples will be collected
as a composite by successive collections at the three locations. Separate samples will be collected for
metals and SVOCs. It is important that the surface SVOC, surface metals, drag sled SVOC, and dust
samples should not be collected from the exact same spots on the field. They should be collected in
proximity to each other at the three locations but their sampling areas should not overlap. Ensuring
that there is no area overlap can be accomplished by placing surface wipe templates and marking the
drag sled area prior to sampling.

7.1.2 Gloves and Glasses

Prior to collecting metals field dust samples, put on clean, powderless nitrile gloves and keep them on
during the entire sampling period. Put on protective glasses to protect against rubber particles that
might be launched during collection.

7.2 Field Dust Samples for Metals

7.2.1	Composite samples will be collected across positions #1, #2, and #5 as shown in Figure 1, by
successive collection and sieving of tire crumb rubber at each location. No background sampling
location dust sample will be collected.

7.2.2	Remove a new plastic spatula from its wrapper.

7.2.3	Bring the 120 mesh (150 |im) stainless steel sieve and the spatula to the first sampling location.

7.2.4	Attach the receiving pan part of the sieve assembly onto the sieve screen.

7.2.5	Use the spatula to scoop crumb rubber from the field onto the sieve screen, filling the sieve to
approximately 50% capacity.

7.2.6	Place the lid on the sieve screen and shake laterally in a vigorous manner for approximately two
minutes (shaking can be started and stopped as needed for rest, and more than one person may
contribute to the shaking).

7.2.7	Avoid getting large rubber pieces or other materials into the pan; if large pieces enter the pan,
remove them with tweezers.

7.2.8	Remove the lid and sieve screen and dump the bulk rubber from the screen back onto the field
from where it was collected. Do not dump the dust collected in the pan.

7.2.9	Re-distribute the rubber back into the field (this may be done after collection at each location or
after all sampling has been completed).

7.2.10	Move to field sample location #2 on the field and repeat steps 7.2.4 through 7.2.8.

7.2.11	Move to field sample location #5 on the field and repeat steps 7.2.4 through 7.2.8.

7.2.12	Following sieving at the final location, remove the pan from the screen and while tilting the pan
slightly use one hand to bang the side of the pan to bring as much dust as possible to one edge of the
pan (note that due to static electricity it will not be possible to dislodge all dust adhering to the pan).


-------
SOP: D-SED-IEMB-029-SOP-02
Date: September 7, 2017
Page: 7 of 14

7.2.13	Place the plastic funnel above the open plastic digestion cup and carefully tap as much dust as
possible from the pan, through the funnel, and into the digestion cup (note that due to static electricity
it will not be possible to dislodge all dust adhering to the pan). A stand or tube holder may be used to
hold the tube during this process, or a second person may assist in the operation. Tightly cap the plastic
digestion cup after as much dust is transferred as possible.

7.2.14	If visible dust remains adhered to the pan, a synthetic bristle brush may be used to brush
collected dust into one edge of the pan, and then through the funnel into the plastic digestion cup.

7.2.15	Visually evaluate the amount of dust collected. The goal is to collect approximately 300 mg or
more of dust, with a minimum of approximately 200 mg. Sample amounts will be estimated by visual
comparison to containers holding approximately 200, 300, and 400 mg of dust.

7.2.16	If the amount of collected dust is not 200 mg or greater based on visual comparison to the
standards, it will be necessary to repeat sample collection across the three locations until at least 200
mg is collected.

7.3 Field Dust Samples for SVOCs

7.3.1	Composite samples will be collected across positions #1, #2, and #5 as shown in Figure 1, by
successive collection and sieving of tire crumb rubber at each location. No background sampling
location dust sample will be collected.

7.3.2	Remove a new plastic spatula from its wrapper (or the original spatula used for metals can be
used).

7.3.3	Bring the 120 mesh (150 |im) stainless steel sieve to the first sampling location. Note that the
same sieve used for metals sample dust collection may be used for the SVOC dust sample collection.

7.3.4	Attach the receiving pan part of the sieve assembly onto the sieve screen.

7.3.5	Use the spatula to scoop crumb rubber from the field onto the sieve screen, filling the sieve to
approximately 50% capacity.

7.3.6	Place the lid on the sieve screen and shake laterally in a vigorous manner for approximately two
minutes (shaking can be started and stopped as needed for rest, and more than one person may
contribute to the shaking).

7.3.7	Avoid getting large rubber pieces or other materials into the pan; if large pieces enter the pan,
remove them with tweezers.

7.3.8	Remove the lid and sieve screen and dump the bulk rubber from the screen back onto the field
from where it was collected; do not dump the dust collected in the pan.

7.3.9	Re-distribute the rubber back into the field (this may be done after collection at each location or
after all sampling has been completed).

7.3.10	Move to field sample location #2 on the field and repeat steps 7.2.4 through 7.2.8.

7.3.11	Move to field sample location #5 on the field and repeat steps 7.2.4 through 7.2.8.

7.3.12	Following sieving at the final location, remove the pan from the screen and while tilting the pan
slightly use one hand to bang the side of the pan to bring as much dust as possible to one edge of the
pan (note that due to static electricity it will not be possible to dislodge all dust adhering to the pan).

7.3.13	Place the metal or glass funnel above the open glass sample jar and carefully tap as much dust
as possible from the pan, through the funnel, and into the jar (note that due to static electricity it will
not be possible to dislodge all dust adhering to the pan). A stand or tube holder may be used to hold the
tube during this process, or a second person may assist in the operation. Tightly cap the jar after as
much dust is transferred as possible.

7.3.14	If visible dust remains adhered to the pan, a synthetic bristle brush may be used to brush
collected dust into one edge of the pan, and then through the funnel into the glass sample jar.

7.3.15	Visually evaluate the amount of dust collected. The goal is to collect approximately 300 mg or
more of dust, with a minimum of approximately 200 mg. Sample amounts will be estimated by visual
comparison to containers holding approximately 200, 300, and 400 mg of dust.

7.3.16	If the amount of collected dust is not 200 mg or greater based on visual comparison to the
standards, it will be necessary to repeat sample collection across the three locations until at least 200
mg is collected.

7.4 HANDLING AND PRESERVATION

8.0 RECORDS

A data collection system will be used to capture information associated with the collection of all
samples. For the dust samples, the sample collection information to be recorded will include the
following, as a minimum: the sample ID, the date and time of the sample collection, the sampling
location, initials or ID number of the field staff member responsible for the sample collection, and any
comments regarding collection (Appendix A). Other information shall be collected as needed to ensure
successful collection and interpretation of data. Please see D-SED-IEMB-030-SOP-01 for recording
sample collection locations on the proper field diagram.

Section B3 in the QAPP addendum details the sample code information. Sample codes used for the
EPA Tire Crumb Rubber Research Study will follow the general naming scheme used by the EPA for
the tire crumb rubber characterization study.

The specific coding information for field dust samples is extracted from the QAPP addendum:

TCRS-R-YY-W-X-Y-Z

Where:

TCRS

Designates the tire crumb rubber research study

R - Participant identification number

1-8; each number assigned to a unique participant where participant-specific ID is required
(personal air, dermal)

0	for all samples not associated with a specific participant

VV - Field ID number

Two-digit code unique to each field (We will use a different unique code for each
field/participant group combination. We will not try to match to any previous field numbers so
we can pre-print all labels. Numbers will go from 70 to 79).

W - Sample type designator
F = sample
D = duplicate sample
B = field blank
C = field control (spike)

X - Method type designator

1	= field dust metals
K = field dust SVOCs

Y - Sample collection location character

C for composite dust samples collected over locations 1, 2, and 5


-------
SOP: D-SED-IEMB-029-SOP-02
Date: September 7, 2017
Page: 10 of 14

Z - Parent/subsample designation character

We will use a value of zero (0) for all parent samples.

We will use the character L to designate laboratory QC samples.

Additional digits may be assigned if any sub-samples are generated.

9.0	QUALITY CONTROL AND QUALITY ASSURANCE

9.1	Field blank (FB) and field control spikes (FC) samples will be prepared and used according to the
schedule outlined in the QAPP addendum Table B-3. For storage, shipping, analysis and quantitation
procedures, FB and FC samples will be prepared and treated in the same manner as the field dust
samples. (This step assumes that suitable dust surrogate material can be found for metals blanks and
spiked controls. Diatomaceous earth will be used for SVOC blanks and spiked controls).

9.2	FB will be deployed to monitor background contamination during storage and analysis. FB samples
will be shipped to the field, their caps will be opened and then immediately closed, and returned to the
laboratory with the samples. FB samples shall otherwise be treated in the same manner as the field dust
samples.

9.3	FC will be deployed to assess recovery of target analytes from a dust surrogate medium under the
same storage and transportation conditions as the field samples. FC will be prepared by adding known
amounts of target compounds to surrogate dust material which is stored in a sealed container. The
container is shipped to the field and returned without opening/handling. It is stored under the same
conditions as field collected samples.

9.4	At least one FB and FC should be included with each batch of dust samples shipped to the EPA
laboratory.

9.5	No duplicate samples will be collected.

Training Requirements


-------
D-EMMD-SSAB-007-SOP-01
Crumb Rubber Particulate Sampling
Effective date 08/212017
Page 6 of 19

All training required is provided by the US EPA. Sample collection should be conducted
by qualified scientific staff trained in the use of the specific field monitoring equipment. If
sampling is conducted by non-scientists, a scientist should oversee the monitoring effort. Training
should include a demonstration and hands-on training by qualified persons with air sampling
expertise. At a minimum, all standard operating procedures (SOPs) and operating instructions
should be reviewed, understood, and followed exactly by the field staff.

4.0 Cautionary Notes or Special Considerations

The sampling systems are powered by sealed lead acid batteries (gel cell). The battery and
pump system should be protected from excessive heat or cold (<50 °F, >104 °F). Pumps and
batteries are shielded from direct exposure by means of an outer protective enclosure. This
enclosure should be used at all times. Precautions must be taken against shorting across the battery
terminals or reversing polarity of the power leads. Shorting of the battery may cause a rapid
discharge that will generate excessive heat and may result in a fire or severe burns. Reversing the
polarity (attaching positive to negative) may damage the pump or battery. Red (+) wires should
be attached to the red (+) battery terminal and black (-) wires should be attached to the black (-)
terminal.

Sampling will take place outside and equipment should be shielded from possible weather
events. Sampling stands should to be set-up so that they are provided protection from tampering.
Sampling stands must also be placed and secured such that no harm will come to children or others
playing in the vicinity of the equipment. Protective enclosures are provided and must be used to
insure safety.

5.0	Procedures

5.1	Loading Filters in the Harvard Impactors for use

5.1.1	In a clean laboratory space, unpack the materials shipped by the NERL-EMMD.
Contact Ron Williams (919-541-2957) if any of the materials defined in the
supplies list are missing or if you wish to use an alternative supply.

5.1.2	While wearing powder-free gloves, install one HI cassette into each HI sampler as
defined by the HI Research Operating Procedure (ROP #07-DEARS).

Note: Since the filters are pre-weighed (tared) it is imperative that the
filter Ids be maintained throughout the handling process so
filter loadings can be accurately determined. See Section 5.2 for
labeling instructions.

• This must be done in a low traffic area, where dust is kept to a minimum. A
laminar flow hood would fit this requirement.

•	Install the cassette with the indicated "top" or "up" side facing the top inlet of
the sampler. Be sure that all of the red rubber seals securing the cassette are in
their proper positions.

•	Close and seal the HI units by use of the two metal catches located on each unit.
Insure that the alignment pins are engaged and that the base and inlet sections
are parallel prior to snapping the latches closed.

•	Keep the zip lock bag that the HI cassette came in.

Note: These bags are labeled with the Id number of the tared filter.
The filter and cassette must be returned to the appropriately
labeled zip lock bag after monitoring.

5.2 Labeling the Sample

Note: Since the filters are pre-weighed (tared) it is imperative that the
filter Ids be maintained throughout the handling process so
filter loadings can be accurately determined when post-weighed.

•	Prepare three labels for each sample using the coding system described below:

TCRS-R-VV-W-X-Y-Z

Where:

TCRS

Designates the tire crumb rubber research study

R - Participant identification number

1-8; each number assigned to a unique participant where participant-specific ID is required
(personal air, dermal)

0 for all samples not associated with a specific participant

VV - Field ID Number

Two-digit code unique to each field (We will use a different unique code for each
field/participant group combination. Previously used field numbers will not be duplicated
so we can pre-print all labels. Numbers will go from 70 to 79).

W - Sample type designator
F = sample
D = duplicate sample
B = field blank
C = field control (spike)


-------
D-EMMD-SSAB-007-SOP-01
Crumb Rubber Particulate Sampling
Effective date 08/212017
Page 8 of 19

X - Method type designator

A = field air PM/metals

Y - Sample collection location character

1 or 2 for on-field air location; 8 for off-field air location

Z - Parent/subsample designation character

We will use a value of zero (0) for all parent samples.

We will use the character L to designate laboratory QC samples.

•	Place one label on the zip lock bag and a second one on the HI unit base at
the time of transfer of the filter cassette from the zip lock bag to the HI unit.

Note: Make sure the three-digit filter code on the zip lock bag matches
the three digit filter code in the full sample code. This number
tracks the tared filter through the post weighing

•	Place the assembled HI unit in a clean large zip lock bag for transport to the
monitoring location.

•	Place the third label on the data collection sheet that will be used to record
the collection information. (See Appendix I for data collection sheet format).
(Note: as an option, the TCRS sample code may be pre-entered on the sheet
instead of using a label).

5.3 Pump Set-up

5.3.1	Transport the assembled HI unit along with their air sampling pump boxes to the
monitoring location along with the data collection sheets, BIOS calibration unit,
calibration cap, GPS unit and any materials needed to secure the monitoring site.

5.3.2	One pump will be set-up at each monitoring location associated with each site with
one exception. A single location will have duplicate monitoring systems so that
precision can be established. The pump set up will be identical for each sampling
filter type.

5.3.3	Select a site that will enable you to place the two near-field sampling stations as near
to the field as safety allows, on different sides of the field (possibly adjacent sides)
and in a downwind position where possible or applicable.

•	Because some fields might be irregular in shape, some compromises might
have to be afforded to the siting of the stations relative to perfect placement.

•	Each pump box should be placed as flat on the ground as possible, even so,
the units will operate in any angle of deflection. An upright (0° angle is best
relative to the HI units built-in weather shielding).

•	Draw the locations on the site map (using black permanent ink) (see D-SED-
IEMB-005-SOP-01 meta-data collection SOP) with sufficient detail to


-------
D-EMMD-SSAB-007-SOP-01
Crumb Rubber Particulate Sampling
Effective date 08/212017
Page 9 of 19

indicate relative positions of each sampling box, their distance from the field
and any other details worth noting (position of any nearby trees or playground
equipment, roadways, etc.).

•	Secure the metal rod to the HI air pump system.

•	Attach the ring to the rod at the indicated mark.

•	Open the pump box, remove the tubing and connect one end to the hose barb
found at the base of the HI unit and the other end to the barb on the right rear
of the pump unit. Remove any kinks in the hose.

•	Slide the hose sufficiently onto the barb so that it is secure (a minimum of
3/8th of an inch). It may be necessary to lightly dampen the tubing to aide
with sliding the tubing onto the barbs.

•	The attached hose should be snug and not easily removed without use of
applied force.

•	Secure the HI unit upside down on the metal rod by inserting the small end of
the impactor head downward through the opening of the ring with the base
resting upside down on the ring. Verify the inlet opening of the impactor is
1.0 ± .1 meter from the ground. Alternatively, a finger clamp may be used to
secure the HI unit.

•	Attach the battery power adapter to the pump unit by inserting the adapter
into the 12V input jack on the right rear of the pump unit.

•	Attach the battery adapter leads to the appropriate terminals of the battery.
Attach the red lead to the positive (+) red terminal and the black lead to the
negative (-) black terminal. Make sure good contact is made.

•	Turn on pump by sliding the on/off switch located on the pump deck to the
"on" position.

Note: The pump flow rate should be "roughed in" to 20 LPM prior to
attaching the HI unit. This will minimize the amount of time
required to fine adjust the pump flow after the HI unit is
attached.

Initial Pump Flow Measurement for Sample Start

5.4.1	Allow the pump to run for 3-5 minutes to warm-up and stabilize.

5.4.2	Attach the HI calibration cap to the Bios DryCal Calibrator using the supplied
tubing. Secure the tubing to the bottom (outlet) barb on the calibrator and to the barb
on the calibrator cap.

5.4.3	Press the "on" button of the BIOS unit.

5.4.4	Press and hold the "Read" button for approximately 3 seconds. This will activate the
unit to make continuous measurements and automatically average 3 replicate
readings.

5.4.4 Remove the top inlet portion of the HI unit by firmly grasping the red center portion
with one hand and with the other hand firmly grasp the top inlet portion and gently
twist and pull the top off. Do not block the inlet openings during this process. Place


-------
D-EMMD-SSAB-007-SOP-01
Crumb Rubber Particulate Sampling
Effective date 08/212017
Page 10 of 19

the inlet on a clean surface (zip lock bag) to avoid contamination.

5.4.5	Attach the HI calibration cap to the HI unit by gently pressing the top onto the red
portion of the HI unit. A slight twisting motion may be necessary to allow the
calibration cap to slide over the O-rings. Be careful not to cut or tear the O-rings
during this process.

5.4.6	Observe the flow rate values being displayed.

5.4.7	Adjust the flow rate to 20.0 ± 1.00 LPM if necessary. While observing the calibrator
display, use a screwdriver to adjust the flow adjustment screw to adjust the flow rate.
Adjustment should be made by gently turning the screw clockwise or
counterclockwise to increase or decrease the pump flow rate. Make adjustments in
partial turns.

5.4.8	Once adjusted to 20.0 ±1.0 LPM allow the flow to stabilize for one minute, reset
the calibrator by pressing the "Stop" button followed by holding the "Read" button
for three seconds. After three readings, record the average flow rate on the datasheet.

5.4.9	Without turning the pump off, immediately remove the calibration cap.

5.4.10	Re-attach the HI inlet to the HI unit.

5.4.12	Record the time and date of the flow measurement in the appropriate section of the
datasheet.

5.4.13	Record the Teflon filter ID number, attached to the outside of the HI unit, in the
appropriate section of the datasheet

5.4.14	Secure pump and place protective enclosure around pump system to prevent
tampering and for safety reasons.

5.5	Final Pump Flow Measurement for Sample End

5.5.1	After sampling for the desired time period, presumed to be ~ three-hour duration,
attach the BIOS calibrator to the HI unit and measure the flow rate at the end of
monitoring period.

5.5.2	Repeat steps 5.4.1through 5.4.6

5.5.3	Do not adjust the pump flow rate at the end of monitoring, simply record the average
value of three measurements as the ending flow rate on the datasheet.

5.5.4	Immediately turn off the HV-30 pump using the on/off switch on the pump deck.

5.5.5	Record the date and time that the pump was turned off on the datasheet.

5.5.6	Remove the BIOS calibration cap from the HI and replace it with its HI inlet.

5.5.7	Remove the tubing from the HI unit and place the HI unit in a zip lock bag and seal.
Ensure that the HI unit is returned to the zip lock bag with the correct sample code
label.

5.5.8	Transport the HI unit to a clean environment for removal of the filter cassette.

5.6	Pump/Equipment Take Down

5.6.1	Disconnect the tubing from the pump unit.

5.6.2	Disconnect the battery leads from the battery and remove the adapter from the pump.


-------
D-EMMD-SSAB-007-SOP-01
Crumb Rubber Particulate Sampling
Effective date 08/212017
Page 11 of 19

5.6.3	Pack all supplies and prepare for departure.

5.6.4	Transport/ship all supplies to the laboratory.

5.7	Removal of Filters from HI Units

5.7.1	In the same clean environment used in 5.1, remove the HI units from their zip lock
bags.

5.7.2	Wearing the powder-free gloves, open the HI units and remove the filter cassette,
returning it to the previously-assigned zip lock bag.

Note: The bags are labeled with the Id number of the tared filter. The filter
and cassette must be returned to the appropriately labeled zip lockbag
after monitoring.

5.7.3	Wipe down all of the equipment that went to the field using lint-free laboratory
wipes that are just slightly moistened to remove immediately transferrable dust.
Repackage all of the materials into their original shipping containers and prepare the
necessary shipping paperwork. All materials should be returned to: Ron Williams,
US EPA, 4930 Page Road, Durham, NC, 27703 (919-541-2957) using next day Fed
Ex or similar overnight delivery service. The kits will contain sealed gel cell
batteries and the NERL Safety and Health Office (541-4307) can assist with any
specialized shipping papers.

5.8	TSP (Total Suspended Particulate) Option

In the event that TSP (total suspended particulate) measurements are being performed (no
PM2.5 size fractionation required), the sampler shall be operated with the oiled impactor stage
removed from the HI. This is how the sampler will be used in support of the Tire Crumb Rubber
Study. This is accomplished by separating the inlet from the impactor stage, removing the oiled
impactor insert and reassembly of the HI. All other aspects of the sampling protocol remain as for
the PM2.5 sample collection (filter selection, duration, gravimetric analysis, etc). It should be noted
that TSP mass collection is not dependent upon a 20 LPM flow rate. It is important to establish an
initial flow rate and a final flow rate with the average being the flow rate used to calculate total
collected air volume. The HI should be operated in a vertical orientation (inlet facing skywards) if
TSP operation is to be used. No inlet is needed under TSP sampling conditions. An initial flow rate
in the range of 15-25 LPM is acceptable. The HV-30 pumps have an upper limit of 30 LPM so
operating the TSP version of the His at 20 LPM is suggested but not a requirement.

6.0 Quality Control

The quality control requirements will allow assessment of the quality of the samples
collected. Determination of possible contamination and reproducibility of the method will be
targeted as data quality indicators.


-------
D-EMMD-SSAB-007-SOP-01
Crumb Rubber Particulate Sampling
Effective date 08/212017
Page 12 of 19

6.1	Field Blanks

•	There should be at least one field blank performed for each day of air monitoring. All
field blanks should be assigned as a sample type code B. This sample uses the same
labeling code as described in Section 5.2.

•	These should be installed within a HI, carried to the field (but not connected to the
sampling box nor having any air pulled through them).

6.2	Duplicate Samples

Duplicate samples shall be taken at a single location during each day of field measurement.
Two sampling systems (pump/inlets) shall be positioned within 2 meters of each other and operated
as specified in Section 5. The purpose of duplicate samples being the determination of precision for
the sampling method in its entirety.

6.3	BIOS Flow Calibrator Calibration

The BIOS calibrator, as previously described, will be used to determine initial and final
flows so that an average flow rate can be determined. This device has been calibrated annually by
the manufacturer and no adjustment of this device is needed. Review the calibration date on the
BIOS to ensure it has been calibrated within the last one year period.

7.0 General Sampling Precautions

Samplers must be placed in an area representative of the average ambient conditions. HI
units should be kept in sealed bags until just prior to the start of the sampling period. Pumps should
never be operated without a particulate filter in-line or with the sampling train sealed. Pumps should
be calibrated against the reference BIOS. Calibration should take place just prior to and
immediately after sampling. The average of initial and final flow rates will be used in conjunction
with the total elapsed sampling time to calculate total air volumes sampled and integrated analyte
concentrations available during the capture period. Air volume calculations will be performed at a
later stage and will not be performed as part of the field sample collection.

8.0	Possible Corrective Actions for Observed Problems During Sampling

8.1	Pump Failure

•	If a pump fails, correct any obvious errors such as kinked lines, battery not fully
charged. If possible, replace the pump.

•	If a replacement pump is unavailable, stop data collection immediately and contact the
EPA's tire crumb rubber study lead (Kent Thomas @ 9195417939) for instructions.
Examples of pump failure include: failure to reach desired flow rate; or failure to
maintain the desired flow rate.

8.2 Possible Contamination of Filters or Supplies

Contact the EPA's tire crumb rubber study lead (Kent Thomas @9195417939) for
instructions concerning possible replacement items or directions concerning decontamination
procedures.

9.0	Recordkeeping

9.1	Data Sheets

All data concerning the data collection will be recorded by the appropriate operator on the
Sample Collection and COC Data Sheets shown in Appendix I. After the data is collected, copies
of the original shall be made and these copies will be labeled and stored in a separate notebook for
safekeeping. The originals are to be returned to the NERL-EMMD supervising scientist along with
the collected samples.

9.2	Calculations

Flow rates are direct readings from the BIOS. Average flow rate is the sum of the initial and
final flow rate divided by 2. The elapsed minutes is the sum total of minutes the pump operated
during the sampling episode. A normal 3 hour run period should have approximately 3 hours X 60
min/hour =180 minutes.

9.3	Chain-of-Custody

Chain of Custody (COC) record forms are shown in Appendix I for samples and QC
samples. The instrument operator will sign-off that the filter is being utilized in the field. The
original of the COC will accompany the filter back to the NERL-EMMD (the originator should
retain a copy for their own records).

Subsequent analysis (i.e. gravimetric analysis, etc.) will be indicated on the sample form by
responsible parties. Original copies of all data forms will be maintained in the NERL EMMD
project files.

Standard Operating Procedure for Collecting and Using Extant Publicly-Available Video
1.0 SCOPE AND APPLICATION

Using publicly available videos (e.g. content posted on YouTube), videography is being used to collect
activity pattern data on children and adults while playing/practicing on artificial turf fields that contain
tire crumb infill at athletic facilities. The purpose of the extant videography is to provide an objective
assessment of user activity patterns potentially impacting exposure to chemicals found in crumb rubber
infill that are difficult to capture consistently using questionnaires.

2.0 SUMMARY OF THE METHOD

Using study acceptance criteria, trained EPA technicians shall identify and download publicly-available
internet videos (e.g., YouTube) of 30 children and 30 adults engaging in activities on artificial turf fields
that contain tire crumb infill. EPA technicians shall document from each downloaded video a description
and image of the selected subject, the type of activity/sport, the type of field (e.g., indoor or outdoor),
and the duration of the activity/sport.

EPA technicians shall record the selected activities of each person on tape for a total of 15 minutes for field
hockey and soccer and 10 minutes for football using three types of paper templates. These activities include
frequency of hand-to-mouth, object-to-mouth, hand-to-turf, and body-to-turf events; number of fingers
in mouth per hand-to mouth event; and activity level duration (i.e., time spent at resting, low, medium,
or high). The activities of each person recorded on the paper templates shall be manually transferred
(using double key entry) into a spreadsheet in MS Excel and a copy of these files made using a thumb
drive.

3.0 DEFINITIONS

SOP - Standard operating procedure

COC - Chain-of-custody

VID - Video identification number

4.0 CAUTIONS

The videography requires the collection of images that may be considered to be personally identifiable
participant data. Also, it is likely that the video footage will include other players and bystanders that are
not the focus of activity data collection, as well as inclusion of field or geographic features that may
make the video location discernible. No personal or site identifying information shall be recorded as
research data as part of the data activity transcription. Any and all human subjects protections
requirements as specified by the Institutional Review Board shall be followed.

5.1	RESPONSIBILITIES

5.2	EPA laboratory technicians shall be responsible for using video websites (e.g. YouTube) or

general search engines (e.g. Google) to identify, download, and securely save acceptable extant
videos of children or adults playing or practicing on artificial turf fields with crumb rubber infill.
They shall also be responsible for extracting data from the downloaded extant videos and
recording selected activities onto three types of paper templates (see Appendices D-F). They
shall be responsible for manually transferring these data into a Microsoft Excel spreadsheet
(using double key entry) and making a copy using a thumb drive.

5.3	The EPA Principal Investigator shall be responsible for maintaining custody of the EPA non-
networked laptop computer and one copy of the extant video files. He or she shall also be
responsible for signing out the non-networked laptop computer and video files to laboratory
technicians to code people's selected activities while playing on synthetic turf fields. In addition,
he or she will be responsible for providing the EPA Database Manager with a copy of the activity
pattern data recorded from the extant video files in an MS Excel file.

5.4	The EPA Database Manager shall be responsible for maintaining one copy of the extant video
files. He or she shall also be responsible for converting the activity data in the MS Excel file into
a SAS database.

Appendix A (List of Example Search Terms), Appendix B (Participant Activity Information on
Extant Video), and Appendix C (List of VIDs by Scenario and Age Group) using Microsoft
Word.

7.2.3	Open Internet Explorer or Chrome on the laptop computer. Use the address bar to navigate to a
video site (e.g. YouTube) or a general search engine (e.g. Google). Using the Example List of
Search Terms (Appendix A), select and type a phrase (e.g., "children's soccer game turf') into
the search area of this website to find a target video. (Note that the search terms will be refined
as experience is gained in determining the types and quality of extant synthetic field-related
video. For example, different sport, practice, or training activities may be identified for
searching).

7.2.4	Select a video from among the search results of 30 minutes or greater length, watch the entire
video, and determine whether it meets the study's acceptance criteria for extant video data.

Acceptance criteria include 1) resolution of taped activity (which must be high enough in quality
to discern when a participant makes contact with the field), 2) continuity of person on tape
(viewer must be able to see 1 participant on video for a minimum of 1 5 minutes for field
hockey and soccer and 10 minutes for football), and 3) applicability for research goals (the
participant and activity must correspond with the scenarios and age groups targeted for high-
end exposure characterization, per the study QAPP). Note: If all acceptance criteria are obtained
(above), up to three individuals can be used per videotape.

7.2.5	If the selected video meets all of the acceptance criteria, type the letters "ss" following the HTTP
text and in front of the website name (e.g. "https://www.ssyoutube.com/watch_") on the address
bar. Press the Enter key to initiate a download of the video as an MP4 audio and video file. Click
on the MP4 file and save it in the Tire Crumb Extant Video folder on the thumb drive. Label the
filename and description as e.g. "Tire Crumb Extant Video VID.mp4," using a number 01
through 60 as the VID based on the sequence in which the videos are retrieved.

Save a copy of Appendices A and C in the Tire Crumb Extant Video folder on the thumb drive.
(Note: The thumb-drive versions of Appendices A and C can be usedfor every video downloaded
and VID assigned during the extant videography.) On Appendix B, type the VID in the top cell
where indicated and save a copy of the file in the Tire Crumb Extant Video Folder on the thumb
drive as e.g. "Appendix B FZD.docx" and continue to step 7.1.6.

If the selected video does not meet the acceptance criteria, repeat steps 7.1.2 through 7.1.4. Apply
the standardized search terms on other video sites or search engines if desired or necessary.

7.2.6	Safely eject the thumb drive containing the saved video file and appendices. Navigate to the
Downloads folder on the networked laptop and delete the MP4 file downloaded in step 7.1.5.

Empty the laptop's Recycle Bin folder to eliminate the file from the networked computer. Log
off and shut down the networked laptop.

7.2.7	Turn on and log onto the non-networked laptop computer by clicking on the "Administrator"
icon, and typing in the generic password "Welcome 1", then insert the thumb drive containing
the saved video file. On the external hard drive, create or locate a folder called Tire Crumb
Extant Video. Copy the downloaded MP4 file, along with Appendices A, B, and C, from the
thumb drive to the Tire Crumb Extant Video folder on the C drive. Safely eject the thumb drive.

7.2.8	Using Windows Media Player, open and play the transferred video file from the Tire Crumb
Extant Video folder. Using Microsoft Word, open the participant information file (e.g.
"Appendix BFZD.docx").

Type the following information on the participant information file (Appendix B) where indicated:
the duration of the video file in hours, minutes, and seconds; the start and stop times (in hours,
minutes, and seconds from the beginning of the video) for the 15 or 10-minute period, respectively,
to be viewed for activity coding; a description of the video subject being followed (i.e., gender
and jersey color and number); and the type of sport or activity (e.g. football, soccer). Take a
screen capture of the videotaped participant using Windows Media Player by pausing the video
on a frame showing the subject, pressing Alt + Print Screen on the keyboard, and pasting the
image into the Appendix B table where indicated. Record the time of the screen shot on the
videotape in Appendix B.

Based on the subject's visual age group (based on other players) and the sport or activity filmed,
type the VID number in a cell under the appropriate column on the List of VIDs by Scenario and
Age Group sheet (Appendix C). (Note: At the conclusion of the extant videography, each of the
three exposure scenarios should have 20 VIDs associated with them, 10 with child subjects and
10 with adult subjects.)

Close Windows Media Player.

7.2.9	Repeat Steps 7.1.2 to 7.1.8 to locate and obtain additional video files.

When extant video collection is ceased at the end of each workday, and also once all study
requirements for extant video collection are fulfilled, print out hardcopies of Appendices B, and
C. Place the printed sheets in a file folder, label the folder "Tire Crumb Extant Video" along with
the current date (e.g. Tire Crumb Extant Video, May 2, 2016), and log off and shut down the
non-networked laptop. Place the thumb drive, laptop computer, and file folder in a locked cabinet
when you are away from your office during the day or at the end of the workday. A f t er
s e ar chi ng for vi de ot ape s for a thr ee da y peri od, return the thumb drive, laptop
computer, and file folder to the EPA Principal Investigator and print with a pen your name,
date, and time on the sign out sheet.

**Once all 60 video files have been selected, place all of the video files onto a thumb drive and
print out final hardcopies of Appendices B and C and give them to the EPA Principal Investigator.

7.3 Data Extraction from Extant Publicly-Available Video

7.3.1 Sign out the non-networked laptop computer from the EPA Principal Investigator. Turn on and
log onto the laptop computer. Open the Tire Crumb Extant Video folder on the C drive. Print out
a hardcopy of each of the 3 Activity Templates for frequencies, number, and duration of selected

subject activities on extant video (Appendices D-F). Select a completed Appendix B document
with a VID, participant description, sport/activity type, and duration listed.

7.3.2	Open the MP4 file with the corresponding VID in the filename, saved in the Tire Crumb Extant
Video folder, using Windows Media Player. Before playing the video, write the VID of the video
on the upper-left of each activity template.

7.3.3	Watch the entire video and familiarize yourself with the participant's activities on videotape.

During the second playback, code the person's activities using Appendix D. On this paper
template, with a pen record with tally marks how many times the participant made hand-to-
mouth, object-to-mouth, hand-to-turf, and body-to-turf contact during the 30-minute time period
Write the date of the analysis on the upper-right of the template where indicated.

7.3.4	Log off and shut down the non-networked laptop. Scan the completed activity templates and
email them as PDF files to the EPA Principal Investigator. Return the laptop and give the
completed hardcopy activity templates to the EPA Principal Investigator. (Note: This procedure
will be completedfor all 60 video files before other selected activities on videotape will be coded
using the two other paper templates, Appendices E and F.)

7.3.5	Repeat steps 7.2.1 through 7.2.4 using the Appendix E Activity Template. For each hand-to-
mouth event seen on the video, make a tally mark in the bottom row of cells under the column
which indicates the number of fingers in mouth (one through five). At the conclusion of the
playback, add the tally marks to determine the total number of times the videotaped participant
was seen with one finger in mouth, two fingers in mouth, etc. in the same cells used for tallying.

7.3.6	Repeat steps 7.2.1 through 7.2.4 using the Appendix F Activity Template. For each of the four
activity levels listed (resting, low, moderate, and high), record the time intervals that the subject
spends at each activity level. For example, if the subject is seen sprinting from 0:15:00 to 0:15:30,
write "0:00:30" to indicate 30 seconds of high activity. At the conclusion of the video, add the
time intervals for each activity level to determine the total duration of time spent by the subject
at each level.

7.4 Electronic Tabulation of Data Extraction Results

7.4.1	Sign out (via sign out sheet) the non-networked laptop computer and the file folder containing
the completed paper Activity Templates (Appendices D-F) from the EPA Principal Investigator.

7.4.2	Turn on and log onto the non-networked computer. Insert a portable thumb drive. Create a MS
Excel spreadsheet and format the spreadsheet according to the template provided in Appendix G
for all VIDs, 01 through 60. Use the keyboard to enter the handwritten activity data from the
paper templates for each person followed on extant video.

7.4.3	Save the spreadsheet as "ExtantActivityData" in the Tire Crumb Extant Video folder on the C
drive. Include the EPA technician's name and the date of data entry at the top of the spreadsheet
above the column headings. Copy the spreadsheet onto the thumb drive in the Tire Crumb Extant
Video folder.

7.4.4	Safely eject the thumb drive. Log off and shut down the non-networked computer. Return the
computer and thumb drive to the EPA Principal Investigator and check-in the materials using
sign out sheet.

7.4.5	The EPA Principle Investigator will upload the MS Excel spreadsheet via the thumb drive onto
a secured EPA server (private L drive folder: TCRS/Activity Data).

7.4.6	The EPA Database Manager will convert the MS spread sheet into a SAS database. The SAS
database will be housed at this location: private L drive folder: TCRS/ActivityDatabase.

8.0 RECORDS

Unique VIDs for each downloaded video are recorded on the video filenames and on the activity
templates for video data extraction. No names or personal information shall be collected if they can be
discerned from the video. No data extraction shall be performed for non-participants. No organization
name, team name, or location information shall be collected in the information extraction. The electronic
video files shall be treated as personally identifiable data and will be managed and secured to allow
access and use only by trained study staff for the intended purpose of turf field activity data collection.
No video or still images shall be publicly released as part of the research effort and research reporting.

Double key data entry, in which the EPA Principal Investigator shall compare the technician's
transcriptions of the same MS activity data file, will be used to verify the accuracy of the electronic data
acquired from the extant videography. Any discrepancies between the two data files will be resolved by
the EPA Principle Investigator by reviewing the original hardcopy version and making necessary
changes as needed to the data file. The EPA Principal Investigator or equivalent will also copy the
downloaded extant video files onto a portable USB drive or external hard drive to be kept in a locked
cabinet.

9.1	QUALITY CONTROL AND QUALITY ASSURANCE

9.2	Extant video quality checks: See section 7.1.4.

9.3	Data and records management: About 10% of the downloaded videos shall be re-coded by the
same trained laboratory technician. In addition, this same subset of videos (10%) shall also be
coded by a second trained staff member or contractor. The EPA Principal Investigator will use
this double key data entry to assess comparability and intra/inter-reviewer consistency for the
subjects' activity data recorded using each type of paper template. The goal is 90% intra-reviewer
and 85%) inter-reviewer accuracy of activity data coding for laboratory technicians. If the coder
fails the intra- and/or inter-reviewer accuracy test(s), he/she will recode a person's activity data
on a video file until they can pass the test.

Standard Operating Procedure for Videography of Activity Characterization Study Participants
1.0 SCOPE AND APPLICATION

Videography is being used to collect activity pattern data on child or adult participants who routinely
play on artificial turf fields that contain tire crumb infill at athletic facilities. The purpose of the video
data collection is to quantify selected activity patterns of children and/or adults while they play/practice
on artificial turf fields to provide objective information on potential exposures to tire crumb rubber
constituents through inhalation, dermal, and ingestion pathways.

2.0 SUMMARY OF THE METHOD

Field technicians shall record child and adult participants that participate in the exposure characterization
component of the Tire Crumb Research Study (TCRS). Field technicians shall videotape these
participants playing/practicing on artificial turf fields for 1.5-hours using a video camera (containing
two video data (SD) cards) that is attached to a monopod.

Laboratory technicians shall translate the selected micro-activities of participants by using a
non-networked laptop computer and a large computer monitor. The technicians shall record the
selected activities of each person on tape for 1,5-hours using three types of paper templates. These micro-
activities include frequency of hand-to-mouth, object-to-mouth, hand-to-turf, and body-to-turf events;
number of fingers in mouth per hand-to-mouth event; and activity level duration (i.e., time spent at
resting, low, medium, or high). The activities of each person recorded on the paper templates shall
be manually transferred (using double-key entry) into a spreadsheet in MS Excel and a copy of these
files made using a thumb drive.

3.0	DEFINITIONS

SOP	- Standard operating procedure

COC	- Chain-of-custody

PID	- Participant identification number

CDC	- Centers for Disease Control and Protection

4.0 CAUTIONS

The videography requires the collection of images that may be considered to be personally identifiable
participant data. Also, it is likely that the video footage will include other players and bystanders that
are not videography participants, as well as inclusion of field or geographic features that may make the
video location discernible. Any and all human subjects protections and training requirements as
specified by the Institutional Review Board shall be followed (currently stated in the Work Assignment).

7.0	PROCEDURES

7.1	Videotaping Study Participants at Enrolled Facilities

7.1.1	CDC research staff shall obtain assent/informed consent to videotape a subset of study
participants that are participating in the activity characterization and exposure measurement
component of the TCRS. This assent/informed consent shall be requested as part of the
eligibility screening interview for users of TCRS-enrolled facilities. When CDC research staff
is not present at a field site, they shall provide contractor field technicians with written hardcopy
documentation and contact information on which participants (by field location) have consented
to have their activities videotaped for 1.5 hours. Note: If CDC research staff is present at the
field site when the participant activity is scheduled, they shall provide the contractor field
technicians with contact information (verbally) on which participants (by field location) have
consented to have their activities videotaped for 1.5 hours.

7.1.2	Contractor field technicians shall attend pre-pilot testing activities to observe a demonstration on
how EPA would like to videotape the selected micro-activities of individual participants while
playing/practicing on synthetic turf fields. The signed names of the field technicians, including
attendance date, shall be recorded onto a sheet of white paper and a copy provided to the EPA
Principal Investigator. This document will be stored in a locked cabinet in the EPA Principal
Investigator's office located in D-576.

7.1.3	EPA staff and/or contractors shall contact study participants who have given informed
consent (via CDC) to be videotaped and arrange the scheduled times to videotape the adults
and/or children while playing/practicing on artificial turf fields.

7.1.4	Contractor field technicians shall videotape individual study participants during the scheduled
appointment times. Perform equipment checks on the camcorder to assure that it is
functioning properly before entering the field. Turn on the camcorder and verify that it
works and then check that the inserted battery is sufficiently charged (> 75%). Place
two new SD cards into the camcorder. Verify the date and time is accurate and is being recorded
on the two SD files. Remove the lens cap and then open the LED screen. Select the recording
option to write a real-time copy of the video files on both SD cards inserted into the camera (i.e.
"Rec Set - Simultaneous Rec"). Attached the camcorder to the monopod. Using a dry erase
board (8.5" x 11") with attached pen, write the participant's PID on it (2-inch size).

7.1.5	Set up the monopod (with camcorder) at one end of the playing field (nearest to the participant
being filmed). Use zoom as needed when videotaping the participant (use 50% frame height).
Move the monopod a few feet (left or right) as needed to obtain unobstructed views of the
participant. To start videotaping the participant, press the Record button on the video camera. At

the beginning of the video, place the dry erase board (with the participant's PID) in front of the
camera lens for five seconds. (Note: If the participant spends less than 1.5-hours
playing/practicing on artificial turffields at the enrolled facilities then videotape for the entire
available playing practice period). Videotape the study participant for 1.5 total hours while
they are playing/practicing on artificial turf fields at the enrolled facilities. This time period
may include on-field breaks for water and/or food. Throughout the videotaping period, be as quiet
as possible and keep a low profile. Concentrate on filming the participant's selected micro-activities
including hand-to-mouth, hand-to-turf, object-to-mouth, and body-to-turf contacts. Do not
videotape the participant at inappropriate times (e.g., changing clothes, bathing, using the
restroom, going to the locker room, leaving the facility); stop the video camera and wait until the
participant has returned to the field and then resume videotaping their activities.

7.1.6	After videotaping the participant for 1.5 total hours, press the Record button on the
camcorder to stop recording. Put on the lens cap. Remove the camcorder from the monopod.
Using the camcorder, review both SD cards to verify that the participant was recorded for the
entire time period (including that the date and time of filming is correct) and that the selected
micro-activities can be clearly observed on these video files (press the "Thumbnail" button and
navigate the contents of each SD card, "A" and "B" to find the files; fast-forward through the
playback to minimize time spent on-site). Then, remove the two SD cards and place them into
the SD card cases. Affix a white label to the SD card case (not directly to the SD card) and write
on it with a pen the PID, field ID, and date. Place the camcorder, SD cards cases containing the
SD cards, and other accessories into the camera bag. Do not leave the video camera, SD cards,
and other accessories in an unlocked car or in a car if the weather is hot (i.e., temperature is
greater than 90°F). Repeat sections 7.1.4 - 7.1.6 for each scheduled participant. Leave the facility
and return to the contractor duty station (keep all items secured in a locked room or cabinet).

7.1.7	After returning to the office in RTP, NC, contractor field technicians s h a 11 turn on and log
onto the non-networked, password-protected laptop computer using your LAN ID and
password. For each study participant, remove the two SD card cases from the camera bag. Store
one of the SD cards (in a plastic case) in a locked cabinet. For the other one, remove
the SD card and insert in into the laptop.

7.1.8	Locate the participant's video files on the SC card (SD/Private/AVCHD/BDMV/STREAM/mts).
Use Windows Media Player to play the video files on the inserted SD card. Rename the video
files to include the participant's PID e.g. "Tire Crumb Field Video (PID).mts and place a copy
of the participant's video files on the C drive, under the folder name: TCRS Video Files." Obtain
a blank COC form (Appendix F) and complete the form using information on stop/start times
from the video player. Eject the SD card from the laptop after all video files have been
appropriately renamed. Place the SD card back into the plastic case. Give this SD card and filled
out/signed COC to the EPA principal investigator (D-576). Repeat section 7.1.7-7.1.8 for each
filmed participant.

7.2 Data Extraction from Study Participant Videos

7.2.1 To code the participant activities on the video files, turn on and log onto the non-networked
laptop computer. Open the TCRS Video Files folder on the C drive. For each participant, do
the following procedures. Print out a hardcopy of the Activity Template - Frequencies of
selected micro-activities on study participant video (Appendix B). Open one of the video files
saved in the TCRS Video Files folder using Windows Media Player. Before playing the video,
write the PID of the video on the upper-left of each activity template. Write the date of the
analysis on the upper-right of the template.

Page 7 of 16

7.2.2	Watch the entire video and familiarize yourself with the participant's micro-activities on videotape.

7.2.3	During the second playback, code the person's micro-activities using Appendix B. On this
paper template, with a pen record with tally marks how many times the participant made
individual hand-to-mouth, object-to-mouth, hand-to-turf, and body-to-turf contacts during
the 1.5-hour time period. Also provide the specific time that each selected micro-activity
occurred by the participant on this template e.g. 00:45:26 (hours, minutes, and seconds after the
start). In addition, record whether the participant was using a mouthguard or wearing gloves (one
or two) on this template. The video may be paused or rewound as necessary to verify types of
contact and specific times. At the conclusion of the video, record the total counts of each micro-
activity at the bottom of the same cells used for tallying. Log off and shut down the non-
networked laptop. Scan the completed activity templates and place them onto an encrypted
thumb drive. Return the thumb drive, and give the completed hardcopy paper activity
templates to the EPA Principal Investigator; The EPA principle investigator will store these
items in a locked cabinet in his/her office. (Note: This procedure will be completed for all 24
video files before other selected activities on videotape will be coded using the two other paper
templates, Appendices C and D.)

7.2.4	Repeat steps 7.2.2 through 7.2.4 using the Appendix C Activity Template. For each hand-to-
mouth event seen on the video, make a tally mark in the bottom row of cells under the column
which indicates the number of fingers in mouth (one through five). At the conclusion of the
playback, add the tally marks to determine the total number of times the videotaped participant
was seen with one finger in mouth, two fingers in mouth, etc. Record the totals at the bottom of
the same cells used for tallying.

7.2.5	Repeat steps 7.2.2 through 7.2.4 using the Appendix D Activity Template. For each of the four
activity levels listed (resting, low, moderate, and high), record the time intervals that the subject
spends at each activity level. For example, if the subject is seen sprinting from 0:15:00 to 0:15:30,
write "0:00:30" to indicate 30 seconds of high activity. At the conclusion of the video, add the
time intervals for each activity level to determine the total duration of time spent by the subject
at each level. Record the total duration of time (in hh:mm:ss format) at the bottom of the
appropriate column for each of the four listed activity levels.

7.3 Electronic Tabulation of Data Extraction Results

7.3.1	Sign out (via the sign-out sheet) the file folder in abinder containing the completed paper Activity
Templates (Appendices B-D) from the EPA Principal Investigator.

7.3.2	Turn on and log onto the non-networked laptop computer. Insert a portable thumb drive. Create
a MS Excel spreadsheet and format the spreadsheet according to the template provided in
Appendix E for all PIDs referenced in the Activity Templates. Use the keyboard to enter the
handwritten activity data from the paper templates for each person followed on video. Perform
a 100% check that all the data entered from individual activity templates into the spreadsheet are
correct.

7.3.3	Save the spreadsheet as "FieldActivityData" in the Tire Crumb Participant Video folder on the
C drive. Include the EPA technician's name and the date of data entry at the top of the spreadsheet
above the column headings. Copy the Tire Crumb Participant Video folder and all its contents
from the C drive onto the inserted thumb drive.

7.3.4	Safely eject the thumb drive. Log off and shut down the non-networked computer. Return the

thumb drive to the EPA Principal Investigator and check-in the materials using the sign-out sheet.

7.3.5	The EPA Principal Investigator will upload the MS Excel spreadsheet via the thumb drive onto
a secured EPA server (private L drive folder: TCRS/Activity Data).

7.3.6	The EPA Database Manager will convert the MS Excel spreadsheet into a SAS database. The
SAS database will be housed at this location: private L drive folder: TCRS/Activity
Database.

8.0	RECORDS

Unique PIDs previously assigned to each participant and his/her activity video are recorded on the video
filenames (as transferred via SD card) and on the Activity Templates. The videographer shall attempt to
minimize videotaping other players or bystanders as much as possible. No names or personal information
will be collected from non-participants. No data extraction will be performed for non-participants. The
electronic video files will be treated as personally identifiable data and will be managed and secured to
allow access and use only by trained study staff for the intended purpose of field-related activity data
collection. No video or still images will be publicly released without the written consent of the study
participant.

Contractor staff shall provide th e EPA Principal Investigator or equivalent with electronic video files
(SD cards) of each study participant. The EPA Principle Investigator will also make a copy of the
participant's video files by placing them on an external hard drive and storing them in a locked cabinet in
his/her office. Individual contractor technicians shall perform double-key data entry of each Activity
Template (B-D) onto separate FieldActivityData electronic files (a and b). Any discrepancies between
the two data files will be resolved by the EPA Principal Investigator by reviewing the original
hardcopy version and making necessary changes as needed to the electronic data files. The EPA
Principal Investigator or equivalent will also make a copy of the participant's data files by placing them
on an external hard drive and storing them in a locked cabinet in his/her office. All records will be archived
by EPA for a minimum of 10 years.

9.1	QUALITY CONTROL AND QUALITY ASSURANCE

9.2	Video camera and accessories checks: See section 7.1.4.

9.3	Data and records management: About 10% of the downloaded videos shall be viewed again
and the selected micro-activities will be quantified (re-coded) onto the hardcopy Activity
Template by the same trained laboratory technician. In addition, this same subset of videos
(10%) shall also be coded by a second trained staff member or contractor. The EPA Principal
Investigator will use this double-key data entry to assess comparability and intra/inter-reviewer
consistency for the subj ects' activity data recorded using each type of paper template. The goal is
90% intra-reviewer and 85% inter-reviewer accuracy of activity data coding for laboratory
technicians. If the coder fails the intra- and/or inter-reviewer accuracy test(s), he/she will recode
a person's activity data on a video file until they can pass the test.

Standard Operating Procedure for Administering the Facility Child User Questionnaire
1.0 SCOPE AND APPLICATION

The Facility Child User Questionnaire is used to collect data on children (< 13 years old) who routinely
play on artificial turf fields that contain tire crumb infill at athletic facilities. The purpose of the
questionnaire is to collect information on the child's activity patterns that may impact the magnitude and
frequency of their exposures to chemicals found in crumb tire infill.

2.0 SUMMARY OF THE METHOD

Research staff administer the Facility Child User Questionnaire to the parents of child participants who
routinely play on artificial turf fields using a computer-assisted interview (CAI) method. The
questionnaire is used to record specific types of data about the participating children including
demographics (i.e., age, gender, and race), education levels, activity-levels, types and frequency of sports
played on fields, frequency and duration of field use, hygiene practices (e.g., hand washing and eating
events), types of clothing worn, and contact rates on turf for different types of activities. Using a laptop
computer, research staff open the Facility Child User Questionnaire via the Epi Info software program
and ask parents each question about their children and record their responses. Research staff save all
responses recorded in the questionnaires prior to exiting the Epi Info software program. They also make
a backup copy of all questionnaire responses using a portable flash drive.

Standard Operating Procedure for Administering the Facility Adult User Questionnaire

1.0 SCOPE AND APPLICATION

The Facility Adult User Questionnaire is used to collect data from adults and older children (> 13 years
old) who routinely play on artificial turf fields that contain tire crumb infill at athletic facilities. The
purpose of the questionnaire is to collect information on the participants' activity patterns that may
impact the magnitude and frequency of their exposures to chemicals found in crumb tire infill.

2.0 SUMMARY OF THE METHOD

Research staff administer the Facility Adult User Questionnaire to adults/older children who routinely
play on artificial turf fields using a computer-assisted interview (CAI) method. The questionnaire is used
to record specific types of data about the participants including demographics (i.e., age, gender, and
race), education levels, activity-levels, types and frequency of sports played on fields, frequency and
duration of field use, hygiene practices (e.g., hand washing and eating events), types of clothing worn,
and contact rates on turf for different types of activities. Using a laptop computer, research staff open
the Facility Adult User Questionnaire via the Epi Info software program and ask the participants each
question and record their responses. Research staff save all responses recorded in the questionnaires
prior to exiting the Epi Info software program. They also make a backup copy of all questionnaire
responses using a portable flash drive.

7.1.3	At the top of the screen, click on the "New Record" button. This questionnaire has a total of 21
questions. Record the participant identification number (PID; obtained from the EPA Tire Crumb
Research Leader), facility name, interview date, study ID number, facility location, and interviewer ID
number at the top of the questionnaire form.

7.1.4	Begin the questionnaire. Ask the participant the first question and record his/her response to the
question. Repeat this procedure for each question.

7.1.5. After the questionnaire is completed go to the top of the screen, select "File" and click on the
"Save" button and save the file as "AdultQuestionnairePIDXX (example: AdultQuestionnairePIDOl).

7.1.6	For the next participant, repeat steps 7.1.3 - 7.1.5.

7.1.7	Exit the Epi Info software program by selecting "File" at the top of the screen and then click on

"Exit".

7.1.8	Make a backup copy of the Tire Crumb Adult Questionnaire folder using only the study
designated portable flash drive. Label the flash drive with a unique identifier (example: TCRS:Adult
Questionnaire). *A11 adult questionnaire files will be uploaded to this one flash drive.

Scope and Application

1.1	This standard operating procedure (SOP) is applicable to the determination of volatile
organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs), and non-targeted
compounds of interest using the Markes International gas chromatograph-mass
spectrometer (GC-MS) time-of-flight (TOF) system following desorption from sorbent
tubes using the Markes International thermal desorber 50:50 (TD 50:50) and the Unity 2.
The TD 50:50 serves as an auxiliary thermal desorption unit that is capable of desorbing
up to 100 sorbent tubes in one analytical sequence. Primary tube desorption occurs in the
TD 50:50, and collected analytes are transferred to the Unity 2, focused on the cold trap,
desorbed off the trap, and transferred to the GC for further separation before final
quantitation in the TOF MS. The analysis method for VOCs, Tire Crumb Compounds and
non-targeted compounds is provided in Appendix A.

1.2	This SOP is written as a companion to D-EMMD-AQB-017-SOP-01, "Standard Operating
Procedure for Determination of Volatile Organic Compounds Desorbed from Sorbent
Tubes Using the Markes International BenchTOF-Select GC-MS TOF System for the Tire
Crumb Research Study."

1.3	The following VOCs are the compounds of interest from the EPA Compendium Method
TO-14A target list (U.S. EPA, 1999a), PAHs of interest from the EPA Compendium

2.0 Summary of Method

VOCs are desorbed from sorbent tubes that have been previously exposed using D-EMMD-AQB-
016-SOP-01, D-EMMD-AQB-015-SOP-01, or D-EMMD-AQB-007-SOP-01 and conditioned
using D-EMMD-AQB-008-SOP-01 (Markes TC-20 tube conditioner). The tubes are fitted with a
stainless steel DiffLok cap on the rear end (outlet) of the tube while an inert coated stainless-steel
cap is placed on the grooved end (inlet) of the tube. Tubes are loaded horizontally into the sampling
trays with the fritted (grooved) end of the tube (inlet) pointing toward the right-hand side. An
analytical sequence is created and initiated using the Ultra-TD software to select the appropriate
desorption method and run the sequence. The TD 50:50/Unity 2 method for determining VOCs,
TCRS compounds and non-targeted compounds is summarized in Appendix A.

An additional method has been optimized on the system to desorb VOCs and PAHs from
Carbograph 2 TD and Carbograph 1 TD dual-bed sorbent tubes. This method is referred to
throughout the SOP as the VOC PAH method and is not in the scope of daily laboratory analytical
practices; the operating parameters and compound target lists are specified separately in Appendix
B(VOC_PAH method).

4.0 Health and Safety

4.1	Gases in high-pressure cylinders are in use in this laboratory. Operators must exercise
extreme care in working with high-pressure gas cylinders.

4.2	Certain areas of the Markes International TD 50:50/Unity 2 are extremely hot, so caution
should be used when attempting to retrieve a hot or jammed tube. Also, the power to the TD
50:50 should be switched off when attempting to retrieve a jammed tube and when
troubleshooting and performing routine maintenance.

5.0 Interferences

5.1	Prior to sampling, sorbent tubes should be conditioned for 1 hour using the tube
conditioning procedure described in D-EMMD-AQB-008-SOP-01 (Markes TC-20) to
remove any VOC contaminants. This process should remove any contaminants that are
residual from prior sampling or that might have outgassed from the sorbent. Conditioning
specifications for sorbent tubes are provided by the manufacturer and should be executed
per manufacturer protocol.

5.2	Prior to analysis, all sorbent tubes must be loaded with internal standards as described in
SOP D-EMMD-AQB-015-SOP-01.

5.3	Two laboratory blanks should be analyzed at the beginning of every desorption sequence
using a conditioned sorbent tube to remove any VOC contaminants from the trap that might
have been adsorbed from the helium purge gas or outgassed from the sorbent in the trap.

5.4	Leak tests should be performed during each analytical run. If repeated leak test failures
occur, see the Unity 2 Troubleshooting Guide, the Unity 2 Operators' Manual, the Markes
International Leak Locating Guide, and the Markes International Thermal Desorption
Training Guide.

5.5	The O-rings located inside of the DiffLok caps might need to be changed periodically due
to wear. See the thermal desorption training guide for O-ring replacement.

5.6	The Peltier cooling will not function properly if the dry gas supply is not switched on. The
dry gas supply must be set to 50-60 psi and have a dew point of less than -50 °C or ice will
form on the Peltier coolers.

5.7	Tubes and their associated DiffLok caps should be handled by the operator only when
wearing either clean white cotton or nitrile gloves to prevent contamination from skin oils
and the VOCs they contain.

Note: DiffLok caps used on sorbent tubes loaded with only VOCs should not be used
interchangeably with sorbent tubes loaded with VOCs and PAHs to ensure there is no cross
contamination of PAHs.

6.0 Personnel Qualifications

Personnel should have knowledge of the following:

•	General laboratory safety practices including appropriate cylinder-handling procedures.

•	Sorbents, breakthrough volumes, flowmeters, mass flow controllers (MFCs), computer
spreadsheets, thermal desorption, gas chromatography, mass spectrometry, data analysis and
validation, and general instrument troubleshooting.

9.0 Quality Control and Quality Assurance

9.1	The TD 50:50/Unity 2 automatically performs a leak test on the tube and the trap prior to
each desorption to verify that the seals at these locations are tight to prevent sample loss.

9.2	The sorbent focusing trap is conditioned by analyzing two laboratory blanks using
conditioned sorbent tubes at the beginning of every desorption sequence to remove
contaminant VOCs.

9.3	Sorbent tubes are conditioned using a 1-hour tube conditioning cycle as described in D-
EMMD-AQB-008-SOP-01 (Markes TC-20) prior to sample collection to remove
contaminant VOCs. Sorbent must be conditioned as specified in protocols provided by the
manufacturer.

Page 7 of 25

9.4	During diffusive sampling, samples can be exposed alone or in pairs depending on the data
quality objectives (DQOs) of the study. The criteria for acceptable results for duplicate
analytical precision, as defined in Compendium Method TO-17, Section 14, "Performance
Criteria for the Solid Adsorbent Sampling of Ambient Air," require agreement within 20%
for duplicate pairs (U.S. EPA, 1999b).

9.5	Depending on the DQOs of a study, laboratory and/or field blanks may be included at the
beginning of the desorption sequence following the helium blank.

9.6	Depending on the DQOs of a study, two to three daily external check standards are included
in each desorption sequence. These standards are used to gauge filament wear in the mass
spectrometer and system stability. Daily external check standards are compared to the
original external check standards that were analyzed with the initial calibration to
determine if VOC concentrations are within ±30% of the current calibration range.

9.7	Internal standards are manually loaded on to each sorbent tube prior to analysis as
described in D-EMMD-AQB-015-SOP-01, to account for instrument drift. The responses
of the internal standards are used by the GC-MS TOF software for calculation of compound
concentrations and by the operator to monitor changes in the sensitivity of the analytical
system. The responses of internal standard compounds should be monitored daily to ensure
their response remains steady. Decreased response for these compounds indicates the
system might need to be optimized and calibrated. See the Markes International
BenchTOF-Select operators" manual for more information. Internal standards are loaded
onto each tube to be analyzed by the instrument. The internal standard consists of four
components: 4-bromofluorobenzene, chlorobenzene-d5, 1,4-difluorobenzene, and
bromochloromethane.

10.0 Standards Preparation

Standards are loaded diffusively onto the sorbent tubes by using an exposure chamber as described
in D-EMMD-AQB-007-SOP-01 or D-EMMD-AQB-016-SOP-01. Standards may also be prepared
using the active loading system as detailed in D-EMMD-AQB-015-SOP-01.

11.0 Procedures

11.1 Establish Communication with the TD 50:50/Unity 2 Thermal Desorber

Power on the TD 50:50 and Unity 2 by pressing the power switch located on the back of
each instrument. After each instrument is powered on, the following procedures are used

11.2	Set and Adjust Initial Flow Rates

Gas flows are set and measured using the electronic carrier control (ECC) function. The
ECC function uses an internal MFC to set and measure gas flows without operator
intervention. Column head pressure is monitored by the GC at the head of the column, and
any variations in pressure are compensated for at the supply. Total flow can be read from
the GC. Flows can be confirmed with a flow meter.

Significant inconsistencies in flows tend to indicate problems with the TD 50:50 or the
Unity 2. Due to the use of MFCs, flow inconsistencies can be more difficult to diagnose as
all flow settings and readouts are digitally controlled. The operator should monitor
chromatography carefully as this is the area in which flow inconsistences will have the
greatest impact.

11.3	Load the Carousel

Although the number and type of samples, blanks, and standards will vary depending on
the DQOs of the project, a rough ordering and brief explanation of tubes on the sample
carousel is as follows:

•	Laboratory blank: a conditioned, unexposed sampling tube that has remained in the
laboratory. Two blanks are run at the beginning of the sequence to determine trap
background levels.

•	Field blank (FB): conditioned, unexposed sampling tube transported to the field and
back.

•	Field Spike (FS): laboratory-exposed 2.0 ppbv sampling tubes transported to the field
and back.

•	Laboratory Control (LC): the field.

•	Shipping blank (SB): unused spare tube transported to the field and back

•	Daily external check standard: a sampling tube passively loaded with the calibration
mixture at a designated concentration level for 24 hours (D-EMMD-AQB-007-SOP-
01 or D-EMMD-AQB-016-SOP-01) actively loaded standards are also available for
use (D-EMMD-AQB-015-SOP-01). Daily check standards are used to monitor
filament wear and system stability. The daily check standards are analyzed at the
beginning, middle, and end of the sample batch to ensure the system remains within
±30% of the calibration range during analysis.

A typical sample batch consists of two laboratory blanks at the beginning of the sequence,
two additional laboratory blanks within the sequence, 18 samples, and three standards for
a total of approximately 27 analyses, which are completed in approximately 27 hours.

Tubes loaded into tube trays for analysis must be QA checked to ensure that tube numbers
are correct and have been loaded in the correct order. The sequence table created in the
TOF-DS software (see D-EMMD-AQB-017-SOP-01) and written on the Markes Unity
Almsco GC-MS TOF analysis sheet (Appendix C) must also be checked for correct tube
order and numbers.

Use the following procedure to load the carousel:

1. Verify that the cylinder valves and the regulator outlet valves are open and that the
regulator outlet pressure is set at the correct value (research helium = 50-60 psig).

2. Open the TD 50:50 door and remove the first tray to load the first 10 tubes in the
analytical sequence (Figure 8). Note: The door of the TD 50:50 should never be opened
during analysis.

Figure 8. Opening the TD 50:50 door to access tube trays.

3. While wearing either white cotton or nitrile gloves, load the top sample tray labeled 1 -
10, starting with the tube slot in the back of the tray, with the laboratory blanks, sample,
and standard sorbent tubes (with DiffLok caps on both ends) by placing them
horizontally in the numbered slots with the fritted (grooved) end of the tube (inlet)
pointing toward the right-hand side and the rear end of the tube (outlet) pointed towards
the left-hand side of the tube tray (Figure 9).

Figure 9. Loading sorbent tubes into the TD 50:50 tube tray.

4. When all slots of the first tray have been loaded with tubes, insert the tray back into
the top slot of the TD 50:50. Guide the tray into the slot slowly until a single click is
felt and gently pull back on the tray. This click indicates the tray is properly seated
(Figure 10).

Figure 10. Loading the sample tray into the TD when full.

5. Repeat steps 2-4 with tube trays 2-10 in the TD until all sampling tubes are loaded.
Be sure to remove and load one tray at a time in the order in which tubes trays are
stacked inside the TD.

11.4 Run the Ultra TD 50:50 and Unity 2 Analysis Sequence

Use the TOF-DS analytical software to create the TOF GC-MS sequence table (sample list)

and initiate an analytical sequence as described in detail in D-EMMD-AQB-017-SOP-01.

Initiate the analysis sequence on the system computer as follows:

1.	Follow the steps in section 11.1 to open the software and create the sequence table.

2.	Click on the three tabs of the method dialog box: Pre-desorption, Tube/Sample
desorption, and Trap Settings to ensure settings match those specified for the method.
The VOC and non-targeted method parameters are detailed in Appendix A.

3.	Once method settings are verified, click the first sample in the sequence table and click
the start icon ([) to begin the TD 50:50 and Unity 2 sequence. An internal schematic
of the Unity 2 system will appear on screen when the sequence begins (Figure 11).

Figure 11. Unity 2 Schematic during desorption.

4. Click on the Sequence Reporter tab of the sequence table to review desorption
parameters as sorbent tubes are desorbed (Figure 12). Throughout the analysis of
samples, it is helpful to view this tab periodically to ensure no tube leak or system leaks
occur. Note: If tube or system leaks do occur, contact the principal investigator to
initiate troubleshooting efforts.

Figure 12. Sequence Reporter tab.

Note: After the samples have been desorbed, they are stored until data is reviewed. Prior
to re-use, tubes must be conditioned and stored as described in D-EMMD-AQB-008-SOP-
01 (Markes TC-20) prior to use.

12.0 Data and Records Management

12.1	The operator must maintain a laboratory notebook in which the experimental and sample
details are recorded.

12.2	The operator must record the date that each cylinder gas is changed in the Markes
International gas logbook.

12.3	Service on the Ultra TD 50:50 and Unity 2 must be documented in the maintenance
notebook.

13.0 Method Performance

13.1	Method detection limits (MDLs) on the order of 35 pptv for benzene have been achieved
for 24-hour exposures.

13.2	Laboratory experiments to evaluate issues such as reverse diffusion, temperature and
humidity effects, linearity of response, MDLs, and ozone effects, are discussed in
McClenny et al. (2005). These experiments were used to determine the subset of the

TO-14A VOCs listed in Section 1.0 that can be determined using Carbopack X diffusive
sampling techniques.

14.0 Maintenance and Troubleshooting

14.1	The O-rings in the hot and cold nozzle of the TD 50:50 and the Viton O-rings on the Unity
2 sampling inlet must be periodically changed due to wear. Worn O-rings may result in
leak test failures. See the operators' manual, leak locating guide and thermal desorption
training guide for o-ring replacement.

Note: The TD 50:50 and the Unity 2 must be powered off during routine maintenance.

14.2	The trap O-ring and filter on the cool non-valve end of the trap should be changed when
trap changes occur or if poorly sealing O-rings are determined to be a leak source. Worn
O-rings can result in leak test failures.

14.3	The focusing trap in the Unity 2 may need to be changed periodically due to wear. This
change is generally performed by a Markes International technician during the annual
performance maintenance service call as heated valve seals are also replaced. After
installation of the new trap, trap conditioning is recommended using the parameters listed
in Table 1. Instructions for changing and conditioning the focusing trap are detailed in the
operators' manual.

Scope and Application

1.1	This appendix applies to the exploration of the desorption of volatile organic compounds
(VOCs) and poly cyclic aromatic hydrocarbons (PAHs) from Carbograph 2TD and
Carbograph 1TD dual-bed sorbent tubes using EPA Compendium Method TO-17 type
procedures (U.S. EPA, 1999a). For this method, the Markes International Ultra TD 50:50
and Unity 2 are interfaced with a Markes International GC-MS TOF system.

1.2	This method is written as a companion to D-EMMD-AQB-017-SOP-01, "Standard
Operating Procedure for Determination of Volatile Organic Compounds Desorbed from
Sorbent Tubes Using the Markes International BenchTOF-Select GC-MS TOF System."

1.3	The standards are prepared by using flash vaporization to load PAHs and active loading to
load VOCs onto sorbent tubes, as described in an SOP that is under development.

1.4	The following VOCs are the compounds of interest from the EPA Compendium Method
TO-14A target list (U.S. EPA, 1999b). Target PAHs are the compounds of interest from
the EPA Compendium Method TO-13A target list (U.S. EPA, 1999c).

Summary of Method

VOCs and PAHs are desorbed from Carbograph 2TD and 1TD dual-bed sorbent tubes that have been
previously loaded using flash vaporization techniques to load tubes with PAHs (SOP under
development) followed by active loading with a gas-tight syringe to load VOCs (D-EMMD-AQB-
015-SOP-01) onto tubes conditioned using the Markes TC-20 (D-EMMD-AQB-008-SOP-01) tube
conditioner. The tubes, with DiffLok caps on both ends, are placed horizontally into the sampling
tray with the fritted (grooved) end of the tube (inlet) pointing towards the right-hand side and the rear
end of the tube (outlet) pointed towards the left-hand side of the sampling tray. An analytical sequence
is created and initiated using the analytical software. The Ultra TD-Tube software is used to create a
desorption sequence by selecting the "PAH and VOCs.mth" desorption method and then initiating
the sequence.

1.0 Scope and Application

This SOP details the extraction and work-up procedures for air samples collected on pre-
cleaned polyurethane foam (PUF) plugs. This method is applicable for extraction of both
indoor and outdoor field samples as well as laboratory generated samples, including
collection from emissions experiments. This SOP is written to encompass a wide range of
analytes and to be applicable across many studies. Analytical performance will need to be
assessed for specific analytes prior to use.

2.0 Summary of Method

There are two acceptable methods for extraction and processing of PUF plugs that will be
detailed in this SOP that involve either Soxhlet or ultrasonic extraction. The method
chosen will depend on availability of materials and equipment, resources, and analytical
performance. For both methods, samples are allowed to equilibrate to room temperature
after removing from freezer storage.

With the Soxhlet extraction method, samples are transferred to clean 150 mL Soxhlet
extractors. Internal standard solution is spiked onto the surface of the samples. Boiling
flasks are filled with 300 mL of 1:1 acetone:hexane along with several boiling chips. The
extractors are assembled on a heating mantle with condensers and heat is applied so the
extraction rate is -20 cycles per hour. The samples are extracted for 16 hours (overnight
is convenient). The extracts in the boiling flasks are allowed to cool and are then
concentrated to 2-5 mL on a rotary evaporator. The concentrated extracts are then
transferred to a 15 mL graduated glass tube along with two 2 mL hexane rinses of the
boiling flask. The extracts are then concentrated to a final volume of 1 mL under
nitrogen. The extracts are then transferred to autosampler vials for analysis.

For ultrasonic extraction, samples are transferred to clean 60 mL amber jars. Internal
Standard solution is added to the PUF. Each jar is filled with 50 mL of 1:1
acetone:hexane and is then sealed with a PTFE-lined cap. The jars are placed in an
ultrasonic cleaner with water level well below the level of the jar cap. The ultrasonic
cleaner is then turned on for 15 minutes. Sample jars are removed from the cleaner and
the extracts are transferred through funnels into 250 mL narrow mouth bottles. The
funnels are rinsed with hexane from a wash bottle after the extracts are added. The
solvent addition, extraction, and transfer is repeated two more times. The extracts in the
bottles are then evaporated to 2-5 mL using a parallel evaporator. The concentrated
extracts are then transferred to a 15 mL graduated glass tube along with two 2 mL hexane
rinses of the bottle. The extracts are then concentrated to a final volume of 1 mL under
nitrogen. The extracts are then transferred to autosampler vials for analysis.

3.0 Definitions

3.1	PUF - Polyurethane Foam sample media.

3.2	SRS - Surrogate recovery standards which are used to evaluate analyte
recovery.

3.3	IS - Internal standard solution which is used in quantification to establish
response ratios.

3.4	Method Blank - Unfortified media that is extracted to evaluate
interferences and possible contamination in the media or lab.

6.0 Interferences

Interferences are any component that interferes with the quantitative analysis.
Interferences should be evaluated prior to applying this method to study samples.
This method may be modified to deal with interferences if necessary as long as
modifications are documented and are acceptable within a studies QA Plan. If
interferences not identified during method evaluation are discovered with study
samples, they will be identified and evaluated as part of a studies ongoing QA/QC
plan.

SOP Title: Determination of Selected Organic Contaminants in Tire Crumb
Rubber Subsamples for Multi-Residue Characterization by Ultra Pressure
Liquid Chromatography/ Tandem Mass Spectrometry (UPLC-MS/MS)

1.	Scope and Applicability

This standard operating procedure (SOP) describes a method for analyzing Tire Crumb
Research Study (TCRS) subsamples for selected organic contaminants in Dermal Wipes, Air
SVOCs, Field Dust, and Field Wipe.

2.	Summary of Method

TCRS samples are extracted with acetone and hexane for gas chromatograph tandem mass
(GCMSMS). After the GCMSMS analysis, approximately one milliliter (mL) is allowed to
evaporate until dryness and reconstituted to lmL with water and acetonitrile. After the extract
is reconstituted, the listed compounds (Table 1) are determined by ultra-performance liquid
chromatograph/tandem mass spectrometer (UPLC7MS/MS, also known as ultra-high pressure
or UHPLC).

3.	Definitions/Acronyms

3.1.	Internal Standard (IS) A fixed amount of reference compound or solution is added to
each sample and standard solution prior to extraction. The ratio of the detector signal
of the native analyte to the detector signal of the internal standard (IS) is compared to
the ratio obtained from the calibration curves where the IS level remains fixed and the
native analyte levels vary. The internal standard is used to correct for minor sample-
to-sample differences in extraction, purification, injection volume, chromatographic
behavior, and mass spectrometry ionization efficiency.

3.2.	Quality Control (QC) Samples Blanks, spikes, and duplicates are used as quality
control measures.

3.2.1.	Blanks are prepared with deionized laboratory water.

3.2.2.	Spikes, deionized water is spiked with known amounts of reference materials
targeted by each analysis. The concentrations of analytes in these QC samples
are compared to their theoretical values for the determination of the accuracy of
the analysis

3.3.	TCRS: Tire Crumb Research Study

4.	Health and Safety Warnings

Personnel must be thoroughly acquainted with the potential hazards of the reagents, products,
solvents, equipment, and procedures described in this SOP. The current Material Safety Data
Sheets (MSDS) for the chemicals used in this method should be consulted. The Health and
Safety Research Protocol for this laboratory activity is on file. Care should be observed with


-------
SOP # D-EMMD-PHCB-SOP-2327-O
Effective Date: 01/29/2018
Page 5 of 31

the use of all compounds specified in this protocol as some may be hazardous if used
incorrectly (e.g., Formic Acid).

Waste Management: Solid, liquid, and glass waste are disposed of in separate containers.
Solvents and samples used in this procedure should be disposed according to Health and
Safety regulations and mindful of appropriate labeling and record keeping

5.	Cautions/Interferences

Do not wash glass bottles in detergent, with other glasses or in washing unit that may have
detergent residue. Washing glassware in a common dishwashing unit can contaminate it with
detergent residues, which contain polyethylene glycol (PEG) and other sticky substances with
vinyl coated steel racks can be and additional source of contaminations.

Do not perform further filtration on pre-filter solvents additional filtering can introduce
contaminations.

Routine instrument maintenance is critical to achieve optimum sensitivity. All laboratory
materials must be determined to be free of contamination to ensure potential background
interferences are minimized.

User must review Waters Manual: Controlling Contamination in Ultra Performance LC®/MS
and HPLC/MS Systems 715001307. Rev. D.

6.	Personnel Qualifications/Responsibilities

10.	Data and Records Management

10.1.	Raw data (including electronic data on individual PC hard drives and group shared
drives) should be backed up, maintained and made available for review.

10.2.	A consistent file naming convention should be documented and used for each specific
project and data type generated.

10.3.	Upon completion, data should be stored in accordance with EPA's record
management policy.

10.4.	All instrument data should be backed up to network drives on a regular basis and
should be archived along with other supporting data and relative correspondence at
the completion of the study.

10.5.	Printed data should be referenced, signed and dated in accordance with the Office of
Research & Development's Policies and Procedures Manual.

11.	Quality Assurance/Quality Control

11.1.	Analysis of standard solutions should result in a best fit regression coefficient of
determination (r2) of 0.99 or greater, using a minimum of six independent
concentrations that bracket the sample concentrations. Sample concentrations
resulting in peak area ratios that are lower or greater than the range of standards
should be reanalyzed with appropriate re- extraction or dilution of original water
sample, respectively.

11.2.	A blank sample must be analyzed every 10 samples. The blank must be prepared for
50:50 Water: Acetonitrile (H20:ACN). When contaminations is noted analysts
should stop the analysis and investigate further to identify the source of
contamination before continuing.

11.3.	A method blank must be analyzed prepared from mobile phase solvents A and B
between every 10 samples. If significant analyte levels (S/N > 5) are found in the
laboratory method blank, the source of contamination should be identified, corrected,
and verified as being eliminated before additional analyses of unknown samples
proceed.

11.4.	For quality control check samples of deionized water fortified at one concentrations
that bracket the six-point curve. A QC standard should be analyzed between every 10
samples. Data is considered acceptable if the calculated recoveries are within 70% of
the expected values.

11.5.	Recovery % = (Actual/Known) * 100 where actual is result received from analysis
and known is the prepared results.

1.0 Scope and Application

Tire crumb rubber (TCR) is a material made from recycled tires that is used as
infill for synthetic turf athletic fields. In order to investigate the potential health
effects from human exposure to the tire crumb material, it is essential to be able to
measure the chemicals from the rubber itself. This method will be used for
extraction and analysis of semi-volatile organic compounds (SVOCs) from the
TCR.

2.0 Summary of Method

Samples of TCR are stored in a freezer at -20° C after receipt at the EPA lab. The
samples are allowed to warm to room temperature, then the sample is
homogenized inside of the collection jar by shaking in a manner to cycle the
content from the bottom to the top of the jar. Two separate lg aliquots will be
removed from each sample, shaking between each aliquot, with each being
transferred to a clean 50 mL polypropylene centrifuge tube. Internal Standard
solution is added to each tube along with a ceramic homogenizer. 10 mL of 1:1
acetone:hexane is then added to each sample tube. The tubes are capped and are
vortex mixed for 1 minute, allowed to sit for 2 minutes, then vortex mixed for an
additional minute. The tubes are then centrifuged at 4000 RPM for 5 minutes. The
solvent is removed and is transferred to a 15 mL vial. A 1 mL aliquot of the
extract is transferred to an autosampler vial for GC/MS/MS analysis. Another
aliquot is transferred to a vial where it is solvent exchanged to methanol for
LC/TOF analysis. Since there is no appropriate surrogate matrix for TCR, QAQC
samples will consist of a duplicate preparations, a reagent spike, reagent blank
and a TCR sample prepared from a TCR designated as a reference sample.

6.0 Interferences

Interferences are any component that interferes with the quantitative analysis of
the compounds used in this study. Interferences will be identified and evaluated as
part of this study's ongoing QA/QC plan.

7.0 Personnel Qualifications

This SOP is written to be used by personnel familiar with the equipment and
procedures that are used. Personnel should be adequately trained and display
proficiency with those techniques prior to using this SOP for sample analysis.

8.0 Method Calibration

The GC/MS/MS instrument should be calibrated for the analytes using the
parameters listed in Tables 3 through 6 prior to sample analysis. Calibrate the
GC/MS/MS system in a range from O.lng/mL to 500 ng/mL using the following
calibration levels (ng/mL): 0.1, 0.5, 1.0, 2.5, 5,10,25,50,100,250,500. The
calibration will be monitored by running a mid-level check standard between
every 10 samples. A check standard must be within ±25% of its prepared
concentration for the calibration to remain valid. If an analyte does not pass the
±25% criterion, but is not found in any of the relevant samples, the analysis may
continue unless the response has decreased to the point of compromising the
ability to detect that analyte.

If a check standard fails, investigate the problem and take corrective action.
Recalibrate the instrument and begin sample analysis from the point of the last
good calibration check.

9.0 Sample Collection, Preservation and Storage

Tire crumb rubber samples will be stored under freezer (-20° C) at the EPA
laboratory. Samples will be allowed to warm to room temperatures prior to


-------
Tire Crumb Rubber SVOC Analysis
D-EMMD-PHCB-03 3 - SOP-01

Page 7 of 14

removing aliquots for analysis and will be returned to freezer storage immediately
following aliquot removal. Sample extracts will also be stored under freezer
conditions -20° C) in cases where analysis cannot be performed immediately.
Recap and store the autosampler vials after the analysis for later use, if needed.
Since PAHs are being analyzed, protect the extracts from light.

10.0 Analytical Procedure

10.1 Sample Preparation, Extraction and Processing

Data will be reviewed by EMMD QA staff. The data quality objectives and
review procedures from the Quality Assurance Project Plan QAPP for the study
being conducted will dictate specific quality assurance practices. All QA practices
will be consistent with the NERL Quality Management Plan.

The Reagent Spike, Reagent Blank and Reference Sample will serve to measure
method performance for each sample. Target recovery for the reagent spike should
be ± 30% of the nominal concentration for each analyte. Any deviations will be
recorded and investigated. The measured concentrations in the Reference Sample
will be recorded and compared among batches to evaluate any potential issues
related to a specific batch as well as to evaluate long-term accuracy of the method as
a whole.

13.0 Records

Chain of custody records will be maintained to document the removal and
extraction of each TCR sample. Those records will be maintained by the study
coordinator upon completion of the analysis. Records of sample preparation and

1.0 Scope and Application

This SOP details the extraction and work-up procedures for dust samples that are
collected from synthetic turf fields. This SOP is written for the extraction and preparation
of samples for analysis of semi-volatile organic chemicals (SVOCs).

2.0 Summary of Method

Dust samples are stored in a freezer at -20° C after receipt at the EPA lab. The
samples are allowed to warm to room temperature before weighing 100 mg of dust into a
50 mL polypropylene centrifuge tube. Internal Standard solution is added to each tube
along with a ceramic homogenizer. 10 mL of 1:1 acetone:hexane is then added to each
sample tube. The tubes are capped and are vortex mixed for 1 minute, allowed to sit for 2
minutes, then vortex mixed for an additional minute. The tubes are then centrifuged at
4000 RPM for 5 minutes. The solvent is removed and is transferred to a 15 mL vial. A 1
mL aliquot of the extract is transferred to an autosampler vial for GC/MS/MS analysis.
Another aliquot is transferred to a vial where it is solvent exchanged to methanol for
LC/TOF analysis. Quality assurance/quality control (QA/QC) samples will consist of a
duplicate preparation (if enough sample is available), a reagent spike, reagent blank,
method spike, method blank and a recovery spike.

3.0 Definitions

3.1.	Synthetic Field Dust Samples - Samples of dust collected from a
synthetic turf field and processed to 150 |im during collection.

3.2.	Spiking Solution - Solution containing stable isotope labeled chemicals
representative of target analytes. Aliquots of this solution are transferred
to blank media to prepare method spikes.

3.3.	Internal Standard Solution (IS) - Solution containing compounds used
to normalize instrument response. This solution is added to all standards,
spikes and blanks as indicated in the procedure.

3.4.	Check Standard - A mid-level calibration standard that is analyzed
between ten sequential sample extracts to determine the continued
accuracy of the calibration curves.

3.5.	Reagent Blank - A matrix free extract that is prepared and analyzed to
assess contamination and interferences from the materials and method.

3.6.	Reagent Spike - A matrix-free extract that has been fortified and has been
through the extraction procedure to determine losses or interferences from
the method.

6.0 Interferences

Interferences are any component that interferes with the quantitative analysis.
Interferences should be evaluated prior to applying this method to study samples.
This method may be modified to deal with interferences if necessary as long as
modifications are documented and are acceptable within a study's QA Plan. If
interferences not identified during method evaluation are discovered with study
samples, they will be identified and evaluated as part of a study's ongoing QA/QC
plan.

7.0 Personnel Qualifications

This SOP is written to be used by personnel familiar with the equipment and
procedures that are used. Personnel should be adequately trained and display
proficiency with those techniques prior to using this SOP for sample analysis.

8.0 Method Calibration

The GC/MS/MS instrument should be calibrated for the analytes using the
parameters listed in Tables 2 and 3 prior to sample analysis. Calibrate the
GC/MS/MS system in a range from O.lng/mL to 500 ng/mL using the following
calibration levels (ng/mL): 0.1, 0.5, 1.0, 2.5, 5, 10, 25, 50, 100, 250, 500. The
calibration will be monitored by running a mid-level check standard between
every 10 samples. A check standard must be within ±25% of its prepared
concentration for the calibration to remain valid. If an analyte does not pass the
±25% criterion, but is not found in any of the relevant samples, the analysis may
continue unless the response has decreased to the point of compromising the
ability to detect that analyte.

If a check standard fails, investigate the problem and take corrective action.
Recalibrate the instrument and begin sample analysis from the point of the last
good calibration check.

1.0 Scope and Application

This SOP details the extraction and work-up procedures for wipe samples that are
collected for both dermal and surface measurements for measurement of semi-volatile
organic chemicals (SVOCs). This SOP is written to address specific conditions used for
samples collected for tire crumb rubber research, but the general procedure can be used
and modified as appropriate providing quality assurance/quality control (QA/QC) criteria
are met and any modifications are recorded in a laboratory notebook.

2.0 Summary of Method

Samples are first removed from freezer storage and are allowed to warm to room
temperature. The jars containing the samples are carefully opened and internal standard
solution is added to the surface of each wipe sample. Each jar containing a dermal or
4"x4" surface wipe is filled with 50 mL of 1:1 acetone:hexane and is then sealed with a
PTFE-lined cap. Jars containing the larger drag sled wipes are filled with 250 mL of 1:1
acetone:hexane. The jars are placed in an ultrasonic cleaner with water level well below
the level of the jar cap. The ultrasonic cleaner is then turned on for 15 minutes. Sample
jars are removed from the cleaner and the extracts are transferred through funnels
containing ~ lOg of anhydrous sodium sulfate into 250 mL narrow mouth bottles. The
funnels are rinsed with hexane from a wash bottle after the extracts are added. The
solvent addition, extraction, and transfer is repeated two more times. The extracts in the
bottles are then evaporated to 2-5 mL using a parallel evaporator. The concentrated
extracts are then transferred to a 15 mL graduated glass tube along with two 2 mL hexane
rinses of the bottle. The extracts are then concentrated to a final volume of 1 mL under
nitrogen. The extracts are then transferred through a 0.2 |im PTFE syringe filter into
autosampler vials for analysis.

3.0 Definitions

3.1	Dermal Wipe - Wipe sample collected from a participant's skin.

3.2	Surface wipe - Wipe collected from a field surface.

3.3	Drag Sled Wipe - Large wipe sample collected using a weighted drag
sled.

3.4	Internal Standard (IS) - Internal standard solution which is used in
quantification to establish response ratios.

3.5	Method Blank - Unfortified media that is extracted to
evaluateinterferences and possible contamination in the media or lab.


-------
D-EMMD-PHCB-068-SOP-01

07/07/2017
Page 4 of 15

3.6	Method Spike - Media that is fortified and extracted to evaluate analyte
recovery from the extraction process.

3.7	Recovery Spike - Unfortified media that is extracted and processed like
the Method Blank. The resulting extract is fortified after sample
preparation is complete. This is used to simulate 100% analyte recovery so
matrix effects that can influence the measured concentrations can be
evaluated.

4.0 Health and Safety Warnings

4.1	Follow the procedures detailed in applicable Health and Safety Research
Protocols.

4.2	Follow proper operating procedures for all equipment and instruments
used.

4.3	Exercise caution when using syringes and avoid inhalation or dermal
contact with all solvents and solutions used in this procedure.

4.4	The ultrasonic cleaner and the water bath inside can become very hot, so
exercise caution when removing containers from the bath and allow the
bath to cool or replace the water with cool water before continuing if the
heat is excessive.

6.0 Interferences

Interferences are any component that interferes with the quantitative analysis.
Interferences should be evaluated prior to applying this method to study samples.
This method may be modified to deal with interferences if necessary as long as
modifications are documented and are acceptable within a study's QA Plan. If
interferences not identified during method evaluation are discovered with study
samples, they will be identified and evaluated as part of a study's ongoing QA/QC
plan.

7.0 Personnel Qualifications

This SOP is written to be used by personnel familiar with the equipment and
procedures that will be used. Personnel should be adequately trained and display
proficiency with those techniques prior to using this SOP for sample analysis.

8.0 Method Calibration

The GC/MS/MS instrument should be calibrated for the analytes using the
parameters listed in Tables 2 and 3 prior to sample analysis. Calibrate the
GC/MS/MS system in a range from 0. Ing/mL to 500 ng/mL using the following
calibration levels (ng/mL): 0.1, 0.5, 1.0, 2.5, 5, 10, 25, 50, 100, 250, 500. The
calibration will be monitored by running a mid-level check standard between
every 10 samples. A check standard must be within ±25% of its prepared
concentration for the calibration to remain valid. If an analyte does not pass the
±25% criterion, but is not found in any of the relevant samples, the analysis may


-------
D-EMMD-PHCB-068-SOP-01

07/07/2017
Page 6 of 15

continue unless the response has decreased to the point of compromising the
ability to detect that analyte.

If a check standard fails, investigate the problem and take corrective action.
Recalibrate the instrument and begin sample analysis from the point of the last
good calibration check.

11.0 Records

Chain of custody records will be maintained to document the removal and
extraction of each wipe sample. Those records will be stored as indicated in the
applicable study's QA plan.

The performance of this procedure will be documented in a NERL research
notebook. This documentation will include details and observations for each
sample batch analyzed.

12.0 Quality Control and Quality Assurance

Data will be reviewed by the analyst. The data quality objectives and review
procedures from the QAPP for the study being conducted will dictate specific
quality assurance practices. All QA practices will be consistent with the NERL
Quality Management Plan.

The method blank, method spike and recovery spike will serve to measure method
performance for each batch of samples. Target recovery for the method spike, and
recovery spike should be ± 30% of the nominal concentration for each analyte.
Any deviations will be recorded and investigated.

1.	Scope and Applications

Ion chromatography (IC) and high resolution inductively coupled plasma mass spectrometry
(HR-ICPMS) are solution phase analytical techniques for the analysis of stable inorganic
ions. This standard operating procedure details the extraction of aqueous and acid soluble
particulate matter from filter media for quantitative analysis to determine water soluble, weak
acid leachable, and total mass extracted from particulate matter (PM) collected on teflon
filters. For a particular inorganic species, by combining the resulting concentration results
with the volume(s) of a specific extraction step, mass per filter can be calculated for a host of
uses.

2.	Summary of Method

Particulate matter from any sampling device collected on a variety of filter media is extracted
to estimate source solubility and total mass through various-stage extraction procedures. This
procedure can involve a 24-hour aqueous filter leach to determine water-soluble inorganic
species. Aliquots of this stage are analyzed for pH, for major cations and anions with IC, as
well as 51 elements with HR-ICPMS.

Following the 24-hour aqueous leach, the remaining filter and leachate are spiked with
hydrochloric and nitric acids to make an acid solution for determination of dilute acid-soluble
inorganic species. After 30 days under ambient conditions, an aliquot is collected for HR-
ICPMS analysis. The filter and remaining dilute acid solution is then spiked to 2% nitric and
1% hydrochloric acids and heated for 3 hours at 70 °C, for the last stage aliquot.

Any stage of this procedure can be performed independently, or as a series, dependent on the
study design.

4. Health and Safety Warnings

4.1.	All acid-cleaning procedures should be performed with the safety of the scientist as the
utmost importance. Lab coat, protective eye wear and particle-free clean room vinyl
gloves should be worn according to basic SHEM training guidelines.

4.2.	Be extremely cautious with concentrated acids. MSDS' are located labeled 3-ring
binders in the clean room gowning area and in the D461A lab.

4.3.	Perform all acid spiking and cleaning procedures in the exhausting laminar flow
hood in D456 Clean Room.

5. Cautions/Interferences
5.1 Cautions

5.1.1.	Unless otherwise noted, all work is carried out in the NERL Class 100 Clean
Laboratory located in D456 of the Research Triangle Park, NC EPA campus.

5.1.2.	A Class 100 Clean lab follows general Clean Lab Guidelines. You are required to
remove footwear (shoes) in the outmost room and wear a clean lab coat and clean
lab footwear (Crocs, or equivalent) in the middle room (gowning room). The
innermost room is the actual laboratory where HEPA-filtered air is continuously
circulated and the temperature and humidity are closely monitored (20 ± 2 °C and
55 ± 5 % Relative Humidity). A clean lab is considered "clean" because of the
filtered air and because it should be free of visible contamination. If there are any
questions or doubts concerning Clean Lab Practices, please see Kasey Kovalcik.

5.1.3.	All filter handling procedures should focus on minimizing contamination.

Perform all filter work in the laminar flow hood. While handling filters in the
laminar hood, it is advisable to turn the HEPA filter fan off. This fan is forceful
enough to make filter handling with forceps difficult.

5.1.4.	Wear vinyl clean room gloves at all times in the clean room.

5.1.5.	Let the MilliQ water run for 30-60 seconds to flush the system, possibly longer
after extended shutdowns (i.e., Monday morning), to achieve 18.2 MQ-cm water.

5.1.6.	Do not move analytical balances. The balances are certified for accuracy
(Precision Weighing, Cary, NC) at their present location and are placed to minimize
air flow, stability, and to stay level.

5.2. Interferences

5.2.1. In trace inorganic analyses, interferences (contamination) are caused by non-clean
lab practices. Refer back to Section 5.1, Cautions.

9. Procedures

9.1. Eutech Instruments pH Probe

9.1.1. Calibration

9.1.1.1.	Remove probe from electrode storage solution and rinse/shake a few times
with MilliQ water. Extra electrode storage solution is located under the
exhaust hood.

9.1.1.2.	Turn meter on.

9.1.1.2.1.	Rinse out 1 buffer container with pH 4.01 buffer solution and then fill
it with the same solution. Repeat this procedure with a second buffer
container for the pH 7.0 buffer solution.

9.1.1.2.2.	Ensure calibration temperature matches room temperature using NIST
traceable thermometer, within ± 1°C.

9.1.1.2.3.	Dip the electrode -2-3 cm into the pH 4.01 standard buffer solution.

9.1.1.2.4.	Press the CAL button to enter calibration mode. The "CAL" indicator
will be shown.

9.1.1.2.5.	Allow sufficient time (can be up to 2 minutes) for the reading to
stabilize. Check by moving the probe in the solution.

9.1.1.2.6.	Once stabilized, press the HOLD/ENT button to confirm the first
calibration point.

9.1.1.2.7.	Rinse with MilliQ water and repeat with pH 7.0 buffer solution
starting with step 9.1.1.2.2.

9.1.1.2.8.	After calibration is complete, press the "CAL" button to exit
calibration mode. The calibration data is now stored.

Measurement

2.1.	Pre-rinse the sample cup with 0.5 mL of the first sample. Shake off excess
sample.

2.2.	In "MEAS" mode, dip the electrode -2-3 cm into the sample.

2.3.	Let the signal stabilize, read to two decimal places and record the reading in
the dedicated laboratory notebook.

2.4.	Rinse the electrode tip with MilliQ water, shake. Empty the sample cup into
an appropriate waste beaker.

2.5.	After every 20 samples (with MilliQ water rinses in between each sample),
submerse the probe in pH 4.01 solution. If the reading is more than 10% off
(3.96-4.05), recalibrate using the steps in Section 9.1.1.

Helpful Hints

¦	Meter will go to standby mode after a few minutes of inactivity or simply after
a fixed amount of time. Just turn the unit back on and proceed with use.

¦	Sometimes it takes a few moments to stabilize the pH reading. Try moving
the meter and then let it settle.

¦	Rinse/shake pH probe glass tip with MilliQ water between measurements.

¦	Collected rinses can be disposed in the sink.

9.2. Sample Tube Acid-Cleaning Procedure for ICPMS Analyses

9.2.1.	Obtain a desired amount of 15 mL and 50 mL tubes to be cleaned (for every 50
mL Fisherbrand tube used, three 15 mL Nalgene tubes are required). Remove the
plastic covers in the first entry-way of the D456 Clean Lab, ensuring that the
tubes and their Styrofoam trays are never placed on the floor. Be sure to wear
personal protective equipment (e.g. lab coat, gloves, safety glasses).

9.2.2.	In the laminar exhausting hood located in the D456 Clean Lab, remove the tube
(15 mL or 50 mL) caps and place the caps in a plastic tub with reverse osmosis
(RO) water.

9.2.3.	Leave the capless tubes in the Styrofoam tray, fill them with RO water and let
them sit in the hood for 1 hour.

9.2.4.	After 1 hour, pour the contents of the tubes into the hood sink and empty the tub
from 9.2.2.

9.2.5.	Loosen the cap slightly of the 20 L carboy of 4.0% nitric and 2.0% hydrochloric
acids (v/v)* to provide airflow. Carefully fill all tubes from the carboy spigot
with the acid solution and securely cap them.

¦	*This acid solution is made by mixing 800 mL Trace Grade nitric acid and
400 mL Trace Grade hydrochloric acid to a total volume of 20 L with MilliQ
water.

9.2.6.	Once all desired tubes are filled with the acid cleaning solution, capped, and
placed back in their Styrofoam tray, carefully take them to D461 and place them
in the oven at 70 °C for 3 hours.

9.2.7.	After 3 hours, carefully remove the tubes and let them cool in a hood before doing
any further work.

¦	CAUTION: mixed acids are considerably more aggressive when hot.

¦	With the oven turned off, these tubes can be left to sit overnight, or they can
be removed and let to sit in a hood to cool. Do not try to work with the tubes
while hot.

9.2.8.	When cool, transport the tubes back to D456.

9.2.9.	Within the laminar exhausting hood, remove the caps from the tubes and place
them in a plastic tub with MilliQ water and pour the acid back into the 20 L
carboy.

9.2.10.	After a tray of tubes is empty, overfill them twice with MilliQ water and discard
rinses. Refill the tubes with MilliQ water and let the tubes sit in the laminar hood
for 1 hour.

9.2.11.	After 1 hour, MilliQ rinse the clean tubes twice again and rinse the caps well.

9.2.12.	Cap the MilliQ-full tubes, seal in ziplock bag (12" x 18"), and store them out of
the way in the D456 Clean Lab until needed.

9.3. Cleaning Procedure for Ion Chromatography (Dionex) Vials and Caps

9.3.1.	Fill plastic 72-position racks with 5.0 mL Dionex vials.

9.3.2.	Fill and empty twice with MilliQ water. Then fill and let them sit overnight in the
laminar flow hood.

9.3.3.	Rinse two more times, shake any remaining droplets, and let dry in the laminar
flow hood.

9.3.4.	Place the dried tubes in a ziplock bag for storage.

9.3.5.	The caps can be soaked in MilliQ water overnight ziplock bag. Try to remove as
much air as possible from the bag to keep the caps submersed in the water.

9.3.6.	The next day, discard the water and shake the caps to remove large droplets.

Place them on a lint-free task wiper and air dry overnight in the laminar hood.

9.3.7.	Place the dry caps in a sealed ziplock bag (12" x 18").

9.4. Three-Stage Filter Extraction Procedure

The following section describes the three-stage, one-container extraction procedure for filters.
Figure 1 shows this process, with accompanying section references. Filters are subjected to a 24-
hour aqueous leach, and 30-day dilute acid leach, and an increased acid concentration under
heated conditions. During each leaching step, it is imperative to know the volume of the
extracting solution so that post analysis processing can calculate the mass of a desired analyte
from the concentration.

3.0 Purpose (Scope and Application)

This document describes a procedure for the preparation of solid matrices such as tire crumb
rubber, soils, sediments or sludge and can be adapted for biological matrices and wipes, for
analysis by inductively coupled plasma mass spectrometry (ICP-MS). It uses a mixture of nitric
acid and hydrochloric acid to improve the extractability of metal analytes.

4.0 Procedure Summary

Organic material in the sample matrix is destroyed and metals that are extractable with a mixture
of nitric and hydrochloric acid are solubilized by microwave digestion in a sealed, pressurized
Teflon vessel. The sample is first allowed to pre-digest at room temperature, and then subjected
to a microwave heating program that increased the temperature of the mixture slowly to 200 °C
and kept it at this temperature for another 30 minutes. The MARS-5 microwave unit (CEM
Corporation, Matthews, NC) used is fitted with a fiber optic temperature sensor to monitor the
temperature of the reference vessel. The instrument has the ability to regulate the temperature
of the sample by adjusting the amount of applied power.

After cooling, the samples are diluted with deionized water and transferred to an acid cleaned
polyethylene or Teflon container that can be centrifuged if needed to separate solid particles.

7.0 Interferences

A clean laboratory environment and trace-clean reagents are required to conduct trace inorganic
analysis. Even when all of these are met, non-clean laboratory practices can lead to introduction
of contaminants into a sample matrix and/or extract that could interfere with instrumental
analysis. Attention to details and experience with clean lab practice procedures are necessary.
The analyst should demonstrate and implement clean laboratory practices. QC measures are put
in place to identify and reduce laboratory contaminants.

During microwave digestion, decomposition of organic rich materials may create high vessel
pressure. This may cause venting of the microwave vessel and result in either loss of analytes and
sample, which must be avoided. Digestion of such samples should be initially subjected to a
reduced initial mass. Gradual and incremental increase of sample size is necessary when the
digestion characteristics of a certain matrix are unknown. The concentration of reagents however
should remain the same.

Health & Safety Precautions

8.0	Hydrochloric acid is a strong mineral acid that is highly corrosive. Nitric acid is a strong
oxidizing agent and a strong acid. Hydrogen peroxide is also a very strong oxidizer. All
these chemicals can cause skin irritation and burns, respiratory irritation, damage to eyes
and organs if not handled properly.

8.1	The analyst should review the Safety Data Sheets (SDS) for each chemical in this
procedure so that safe working procedure must be achieved. SDS are located in a properly
labeled 3-ring binder in CHL-43 Laboratory and are also available on-line.

8.2	All of the hazardous chemicals used in this procedure should be handled only while using
proper personal protective equipment (PPE) such as: gloves, lab coats, safety glasses and
appropriate close-toed shoes. Contact lenses may not be worn while working in the
laboratory. Fume hoods must be utilized whenever possible to avoid potential exposure.
Perform dilutions by adding acid to water.

8.3	The analyst should be familiar with the location and proper use of the fume hoods, eye
washes, safety showers, and fire extinguishers.

8.4	Waste disposal should follow the recommended EMMD procedures for waste disposal
whenever applicable. Contact the onsite EMMD's SHEMP Manager when the container is
full for disposal.

8.5	Rapid and/or explosive generation of gases can occur during the digestion of samples with
a high organic content such as oils, tissues and rubber based materials. The analyst should
follow the advice given in paragraph 2 of Section 7.0.

8.6	When working with samples of unknown composition, always perform a pre-digestion
step in an unsealed, open vessel, allowing a minimum of 15 minutes time for reaction of
volatile or easily oxidized compounds to subside before sealing the vessel and microwave
heating.

8.7	Never heat liquids in a sealed vessel that is not equipped with a pressure relief device.

8.8	Microwave digestion vessels can be highly pressurized and should be handled with care.
To minimize internal pressure, the microwave digestion vessels should be allowed to cool
to ambient temperature before opening. In addition the vessels should be vented in a
fume hood to release excess fumes.


-------
SOP # D-EMMD-ECB-003-SOP-01
Microwave Assisted Digestion of Solid Matrices

Page 8 of 21

8.9	Fumes from the microwave unit should be exhausted to a hood.

8.10	Organic solvents should not be subjected to microwave radiation as they may react
explosively. Organic solvent such as ethanol when mixed with concentrated acids like
nitric acid can react violently, even explosively, and this without applied heat.

8.11	All unused acids should be properly disposed in the acid waste collection container.

Microwave Extraction Protocol

All digestion and volumetric vessels must be acid washed and rinsed with deionized water before

use. Refer to Appendix C. for the step by step procedure for cleaning vessels.

9.1 Microwave Extraction of Tire Crumb Rubber Samples

Use the sets of 12 XP-1500 Plus microwave vessels which also include a control vessel. The
liner has a capacity of 100 mL and is made of Teflon® TFM, an advanced composite Teflon.
These vessels are adequate to handle the high temperature required to digest the rubber
material and can withstand a maximum pressure of 800 psi.

Bulk tire crumb rubber samples will be used without sieving or size reduction, to minimize
contamination.

9.1.0	Place the microwave vessel and cap on a tared balance and record the weight in the
digestion Notebook. Mix the sample thoroughly. Remove the cap and transfer 0.25 g
(within 0.02 g) of sample to the tared vessel. The sample must be placed in the
bottom of the liner. The side walls of the liner must be free of sample deposits.

9.1.1	Determine the weight of concentrated nitric acid and hydrochloric acid that will
make a slurry containing 9 mL HN03 and 3 mL HCI, taking their specific gravity into
consideration (Section 11, no. 11.1). According to the manufacturer SDS, the Optima
nitric acid has a specific gravity of 1.40 and the Optima HCI 1.18.

9.1.2	Tare the vessel, add concentrated nitric acid to the vessel and record the weight of
the acid. Zero the vessel one more time, add the hydrochloric acid and record the
weight. Make sure that the acid mixture covers the sample. Place a new rupture
membrane in the vessel cap and seal firmly by hand. Weigh the vessel and record
the weight before digestion.

9.1.3	Repeat the above procedure for a batch of up to 24 samples. Place a duplicate of
the sample most likely to be more reactive in the MARS-5 control vessel. Insert the
temperature probe in the control vessel sapphire well and secure the pressure line
to the cap. The control sample is not normally used for data since it may become
contaminated from the pressure monitoring line.

SOP # D-EMMD-ECB-003-SOP-01
Microwave Assisted Digestion of Solid Matrices

November 1, 2016
Page 9 of 21

9.1.4	MARS-5 System - The microwave unit can only process a set of 12 samples in XP-
1500 vessels at a time. Place the turntable into the microwave cavity. Place each
vessel into the turntable. Connect pressure and temperature lines to their
microwave ports.

9.1.5	Use program ECBTRC-1 1-4 vessels, ECBTRC-2 for 4-8 vessels and ECBTRC-3 for 9
- 12 vessels. These programs are described in Appendix A. Record the temperature
after ramp up and before the end of the digestion cycle.

NOTE: Due to the variable nature of the samples, some may be particularly reactive
and require a gentle pre-digestion to volatize potentially explosive compounds. For
example, samples with larger and more irregular particles may be targeted for this
extra step. Any change in the conditions used for digestion will be noted in the lab
notebook used to document sample preparation.

9.1.6	After digestion is complete, allow the vessels to cool until the temperature drops to
less than 30 °C. There is no need to open the microwave door to help cool the
vessels. Once the method run is complete, the MARS-5 system will go through an
automatic cooling cycle.

9.1.7	Vent the vessels in a fume hood and weigh to verify that no significant amount of
solution was lost.

9.1.8	Place the microwave vessels in the fume hood. Add 250 piL of hydrogen peroxide in
each vessel and allow enough time for the hydrogen peroxide to oxidize remaining
organic material. The extract should be quite clear at the end of the process.

9.1.9	Transfer the solution quantitatively to a 60 mL LDPE polyethylene sample bottle and
bring to a final weight of 50 g of solution using deionized water. Allow solids to
settle and if needed, centrifuge the sample. This sample will be further diluted and
analyzed by ICPMS. In addition, a filtration step can be included if judged necessary,
using a 0.45nm membrane filter.

9.1.10 Use the in-house developed Excel program to do all calculations and print digestion
log to be placed in the digestion log binder or paste in the project laboratory book.
The excel program will compute the Calculated Weight before Digestion, Percent
Difference, Recovery Percent and Dilution Factor.

10.0 Quality Assurance / Quality Control (QA/QC)

10.0 Blank: A preparation blank will accompany each digestion batch of 24 or fewer samples.
The mixture of acid reagents (Section 9.1.1) will be used. The blank is used to track
potential contamination during sample preparation and extraction. The blank is treated as
a regular sample. If a sample is filtered before analysis, than a blank will also need to be
filtered to assess if the filter is contributing any contamination.

Page 10 of 21

10.1	Laboratory Control Sample (LCS): Another reagent blank will be prepared and to this, will
be added 250 |al of the custom spike standard solution (Section 5.5) before digestion. The
LCS results will be used to determine if the laboratory can perform the analysis in a clean
matrix.

10.2	Laboratory Duplicate (Dup): One tire crumb sample will be digested in duplicate with
each batch of 24 or fewer samples to check the precision of the digestion method.

10.3	Matrix spike (MS): With each digestion batch of 24 or fewer samples, an additional
subsample taken from a randomly selected tire crumb container will be prepared. This will
be spiked with 250 |al of the standard mixture of analytes and digested. The MS is used to
document the effect of the sample matrix on analyte recovery.

10.4	Standard reference material: A standard reference sample (if available for the sample
matrix type to be analyzed) should be included with each batch of samples processed. As
of now there is no standard reference material available for tire crumb rubber.

10.5	Digestion Percent Difference: The percent difference between the weight after digestion
and the calculated weight before digestion should not exceed 10 %. If the percent
difference does exceed 10%, investigate the reason, correct, and re-digest the sample.

10.6	Pressure and Temperature Monitoring for the MARS-5 system: Examine the pressure and
temperature monitoring graph. If the pressure or temperature deviates from the set point
by 15 % or more after ramp up and before the end of the digestion, investigate the
problem, and consult the group leader to determine if re-digestion is necessary.

Determine if the sample in the monitoring vessel was the cause and if not, the microwave
may need recalibration (refer to Appendix B and C).

11.0 Calculations

11.1	Acid Weight = desired volume x density

Optima Nitric acid weight = 9 mLx 1.40 g/mL = 12.60 g
Optima Hydrochloric weight = 3 mLx 1.18 g/mL = 3.54 g

11.2	Calculated Weight before Digestion: The Excel program will add the vessel weight, the
sample weight and the acid weight to give the expected weight before digestion in grams.

11.3	Percent Difference: The Excel program will divide the weight after digestion by the
calculated weight before digestion and multiply by 100 to give a percent difference.

11.4	Dilution Factor: The Excel program will add the sample weight and the acid weight
adjusted for specific gravity, and divides the result by the sample weight to obtain the
dilution factor used in data calculations.

12.0 Miscellaneous Notes

12.0	MARS-5 System: Monitor the pressure and temperature during the digestion process. If
the expected temperature or pressure is not maintained during the digestion, investigate
the cause, and consult the group leader to determine if re-digestion is necessary.

12.1	Follow instructions in Appendix B and the MARS-5 instruction manual if recalibration of
the pressure sensor or temperature sensor is required. The pressure sensor calibration
constant is 4315-4316-0621-0623-6637-2241.

12.2	The digestion data will be stored on the individual analyst computer and on a designated
EPA shared drive. Additionally, hard copies of the digestion data will be placed in the Tire
Crumb digestion binder located in CHL-43.

Appendix A: Microwave Extraction Programs

Two microwave accelerated reaction systems MARS-5 are located in CHL-25 laboratory. The digestion
programs use a ramp to temperature approach and are available on both systems. Depending on the
number of vessels used, the analyst should choose the appropriate ECBTRC- method.

1.	Program Name: ECBTRC-1

Max Power = 400W
% Power = 100%

Ramp = 20 minutes
Pressure = 0 psi
Temperature = 200 °C
Hold Time = 30 minutes
Number of Vessels = 1 to 4

2.	Program Name: ECBTRC-2

Max Power = 800W
% Power = 100%

Ramp = 20 minutes
Pressure = 0 psi
Temperature = 200 °C

Appendix B: Quality Control Test for MARS-5 Vessels and Sensors

This quality control test should be performed only if deemed necessary.

1.	Place 50 mL Dl water in the control vessel (XP1500+, or HP500+), and assemble as you normally
do with the temperature and pressure sensors attached.

2.	Place the control vessel in the turntable and connect the sensors. (No other vessels are run
during this test.)

3.	Go into the CEM Directory and load the preprogrammed "QC ESP/EST" method.

4.	Allow the method to run, observing the temperature and pressure readings. When you get to
stage 5, record the temperature once the pressure has begun controlling at 200psi. The
temperature should be 200°C +/- 10C at 200psi. If it is not, either the temperature or pressure
sensor is out of calibration.

5.	Allow the vessel to cool to < 50°C. Measure the volume of water remaining in the vessel. If you
put 50mL in, you should get 50mL back out. If the volume is < 50mL, then there is a leak.

Note that a vessel can be leaking and still pass the QC test (200psi = 200°C). Look for volume loss
instead.

6.	If the QC test fails (i.e., you do not get 200°C +/-10C at 200psi), then recalibrate the temperature
probe and repeat the QC test.

Appendix D: Procedure for Cleaning Vessels

This cleaning sequence has been determined to be adequate to minimize contamination in glass,
polyethylene, polypropylene or PTFE vessels.

1.	Prepare cleaning solution by adding a small amount (approximately 5 mL) of concentrated
Citranox (Alconox Inc.) liquid soap to a tub of reverse osmosis (RO) water (~6 L). Remove all
markings and residue from vessels using a designated lab brush or methanol if necessary.
Submerge vessels in soap solution and allow to soak for a few minutes.

2.	Clean the vessels with a lab brush. Rinse three times with reversed osmosis water and one
last time with deionized water.

3.	Place the vessels in an acid bath containing 10% (v/v) Trace-metal clean concentrated HN03

in Dl water, and let them soak overnight (and up to 48 hours).

4.	Remove vessels, rinse three times with deionized water.

5.	Allow vessels and lids to air dry (open end down) on a clean surface.

6.	This step applied only to the XP-1500 microwave digestion vessels that already went
through the above cleaning steps.

Use the Optima grade acid to prepare 1 liter of 10% Nitric acid.

-	Fill the vessels approximately half way with acid (~50 mL) and secure the lids. Don't forget
to place a safety membrane in the vent cap.

-	Place the vessels in the carousel and microwave the solution using extraction program
ECBCM-1, -2 or -3 (Appendix E) depending on the number of vessels.

7.	After cooling to room temperature, pour the nitric acid solution back into the Teflon
cleaning solution container. Rinse vessels and caps three times with deionized water, and
allow to air dry.

8.	All sample bottles and microwave vessels should be capped and stored in sealable plastic
bags or plastic containers to prevent contamination.

9.	Label bag or container with the cleanup date and batch number.

When cleaning polyethylene conical tubes with external graduation, soaking in an acid bath is not
recommended as the material used to graduate the tubes can be removed upon contact with acid
and therefore can become a source of contamination.

-	Remove the caps and let the tubes stand in the Styrofoam base.

- Pour Dl water into each tube and secure the caps. Let the sealed tubes soak for a few

minutes, shake well and discard the water. Repeat this step two more times.

-	Fill each tube with 10% nitric acid and let sit overnight or at least twelve hours at room
temperature in the Styrofoam container with their lids on.

-	The next morning, the sealed tubes are reversed to give the cap a chance to get in contact
with the acidic solution. Leave the tubes in that position for at least four hours.

-	Pour the acid content into an acid cleaning bottle.

-	Rinse tubes and lids several times with deionized water and allowed to air dry.

-	Cap the tubes, place them back in their Styrofoam base and keep them seal until usage.

SOP Title: total nitric acid extractable metals from wipe samples by microwave

DIGESTION

Scope and Applicability

This document describes a procedure for the preparation of wipe samples, for elemental analysis by
inductively coupled plasma mass spectrometry (ICP-MS). It uses a mixture of nitric acid and
hydrochloric acid to improve the extractability of metal analytes.

This standard operating procedure has been prepared for use of the Environmental Measurement
and Monitoring Division (EMMD) of the U.S. Environmental Protection Agency and may not be
specifically applicable to the activities of other organizations. It is a modified version of ECB-003- SOP-
01 [Ref. 13.1]. It uses the multi-element nitric acid/ hydrochloric acid-leach microwave-assisted
digestion procedure described in EPA Method 3051a [Ref. 13.2] which renders a sample suitable for
ICP-MS analysis. This procedure is limited to use by, or under direction of, chemists and technicians
who have demonstrated proficiency with the procedure. This document has not been through the
Agency's peer review process nor the EMMD clearance/publication process. THIS IS NOT AN OFFICIAL
EPA APPROVED Method.

Summary of Method

Organic material in the sample matrix is destroyed and metals that are extractable with a mixture of
nitric and hydrochloric acid are solubilized by microwave digestion in a sealed, pressurized Teflon
vessel. The sample is first allowed to pre-digest at room temperature, and then subjected to a
microwave heating program that increased the temperature of the mixture slowly to 200 °C and kept
it at this temperature for another 15 minutes. The MARS-5 microwave unit (CEM Corporation,
Matthews, NC) used is fitted with a fiber optic temperature sensor to monitor the temperature of the
reference vessel. The instrument has the ability to regulate the temperature of the sample by
adjusting the amount of applied power.

After cooling, the samples are diluted with deionized water and transferred to an acid cleaned
polyethylene or Teflon container that can be centrifuged if needed to separate solid particles.

Health and Safety Warnings

4.0	Hydrochloric acid is a strong mineral acid that is highly corrosive. Nitric acid is a strong
oxidizing agent and a strong acid. Hydrogen peroxide is also a very strong oxidizer. All these
chemicals can cause skin irritation and burns, respiratory irritation, damage to eyes and
organs if not handled properly.

4.1	The analyst should review the Safety Data Sheets (SDS) for each chemical in this procedure so
that safe working procedure must be achieved. SDS are located in a properly labeled 3-ring
binder in CHL-43 Laboratory and are also available on-line.

4.2	All of the hazardous chemicals used in this procedure should be handled only while using
proper personal protective equipment (PPE) such as: gloves, lab coats, safety glasses and
appropriate close-toed shoes. Contact lenses may not be worn while working in the
laboratory. Fume hoods must be utilized whenever possible to avoid potential exposure.
Perform dilutions by adding acid to water.

4.3	The analyst should be familiar with the location and proper use of the fume hoods, eye
washes, safety showers, and fire extinguishers.

4.4	Waste disposal should follow the recommended EMMD procedures for waste disposal
whenever applicable. Contact the onsite EMMD's SHEMP Manager when the container is full
for disposal.

4.5	Rapid and/or explosive generation of gases can occur during the digestion of samples with a
high organic content such as oils, tissues and rubber based materials. The analyst should
follow the advice given in paragraph 2 of Section 5.0.

4.6	When working with samples of unknown composition, always perform a pre-digestion step in
an unsealed, open vessel, allowing a minimum of 15 minutes of time for reaction of volatile
or easily oxidized compounds to subside before sealing the vessel and microwave heating.

4.7	Never heat liquids in a sealed vessel that is not equipped with a pressure relief device.


-------
SOP # D-EMMD-ECB-013-SOP-01
Effective Date: 11/13/17
Page 6 of 17

4.8	Microwave digestion vessels can be highly pressurized and should be handled with care. To
minimize internal pressure, the microwave digestion vessels should be allowed to cool to
ambient temperature before opening. In addition, the vessels should be vented in a fume
hood to release excess fumes.

4.9	Fumes from the microwave unit should be exhausted to a hood.

4.10	Organic solvents should not be subjected to microwave radiation as they may react
explosively. Organic solvent such as ethanol when mixed with concentrated acids like nitric
acid can react violently, even explosively, and this without applied heat.

4.11	All unused acids should be properly disposed in the acid waste collection container.

Cautions/Interferences

A clean laboratory environment and trace-clean reagents are required to conduct trace inorganic
analysis. Even when all of these are met, non-clean laboratory practices can lead to introduction of
contaminants into a sample matrix and/or extract that could interfere with instrumental analysis.
Attention to details and experience with clean lab practice procedures are necessary. The analyst
should demonstrate and implement clean laboratory practices. QC measures are put in place to
identify and reduce laboratory contaminants.

During microwave digestion, decomposition of organic rich materials may create high vessel
pressure. This may cause venting of the microwave vessel and result in either loss of analytes and
sample, which must be avoided. Digestion of such samples should be initially subjected to a reduced
initial mass. Gradual and incremental increase of sample size is necessary when the digestion
characteristics of a certain matrix are unknown. The concentration of reagents however should
remain the same.

Personnel Qualifications/Responsibilities

The procedures detailed in this SOP are to be conducted only by staff trained by the SOP contact
listed on the cover page or the contact's designee. Training will be documented and the trainee will
be allowed to conduct the procedures after demonstrating proficiency at the discretion of the trainer.

Equipment and Supplies

7.1 CEM Corporation Microwave Accelerated Reaction System, Model MARS-5 which includes a
microwave power system with selectable output of 0 - 1600 watts, a fluoropolymer-coated
microwave cavity and rotating turntable. The instrument is fitted with a pressure sensor ESP-
1500 Plus and fiber optic temperature sensor model RTP-300 Plus (temperature range 40 to
250 °C) that can be used to monitor the XP-1500 Plus vessels. Although both sensors are
factory calibrated, it is strongly encouraged to check the instrument temperature reading
against an external thermometer. A step by step procedure for calibrating the temperature
probe of the MARS-5 instrument is reported in Appendix C. Please also refer to the MARS-5

Microwave Extraction of Wipe Samples

Use the sets of 12 XP-1500 Plus microwave vessels which also include a control vessel. The

liner has a capacity of 100 mL and is made of Teflon® TFM, an advanced composite Teflon.

These vessels are adequate to handle the high temperature required to digest the wipe

material and can withstand a maximum pressure of 800 psi. Whole wipe samples will be used.

9.1.0	Place the microwave vessel and lid on the analytical balance and record the weight in
the digestion Table. Using acid cleaned forceps (made of teflon or acid resistant
plastic), transfer 1 wipe sample (approximately 4.5 - 5.0 g) into the tared vessel. Record
the weight of the wipe. Tare the sample vessel. Place it in the fume hood and add 9 mL
of concentrated nitric acid and 3 mL of hydrochloric acid. Make sure that the entire
wipe is covered with reagent. Wait approximately 20 minutes before closing the vessel.
Caution: The reaction between wipe and acid is rapid. It produces brown fumes and is
quite exothermic (the experimentalist should exert extreme caution when performing
this task).

9.1.1	Place a safety membrane in the vessel cap and seal firmly by hand. Weigh the vessel
and record the weight before digestion.

9.1.2	Repeat the above procedure for a batch of up to 24 samples. Insert the temperature
probe in the control vessel sapphire well and secure the pressure line to the cap. The
control sample is not normally used for data since it may become contaminated from
the pressure monitoring line.

9.1.3	MARS-5 System - The microwave unit can only process a set of 12 samples in XP-1500
vessels at a time. Place the turntable into the microwave cavity. Place each vessel into
the turntable. Connect pressure and temperature lines to their microwave ports.

9.1.4	Use program ECBTRCW-11-4 vessels, ECBTRCW-2 for 4 - 8 vessels and ECBTRWC-3
for 9-12 vessels. These programs are described in Appendix A. Record the
temperature after ramp up and before the end of the digestion cycle.

9.1.5	After digestion is complete, allow the vessels to cool until the temperature drops to
less than 30 °C. There is no need to open the microwave door to help cool the vessels.
Once the method run is complete, the MARS-5 system will go through an automatic
cooling cycle.

9.1.6	Vent the vessels in a fume hood and weigh to verify that no significant amount of
solution was lost.

9.1.7	Place the microwave vessels in the fume hood. Add 250 piL of hydrogen peroxide in
each vessel and allow enough time for the hydrogen peroxide to oxidize remaining
organic material. The extract should be quite clear at the end of the process.

9.1.8	Transfer the solution quantitatively to a 60 mL LDPE polyethylene sample bottle and
bring to a final weight of 50 g of solution using deionized water. Allow solids to settle


-------
SOP # D-EMMD-ECB-013-SOP-01
Effective Date: 11/13/17
Page 9 of 17

and if needed, centrifuge the sample. This sample will be further diluted and analyzed
by ICPMS. In addition, a filtration step can be included if judged necessary, using a 0.45
pirn membrane filter.

9.1.9 Use the in-house developed Excel program to do all calculations and print digestion log
to be placed in the digestion log binder or paste in the project laboratory book. The
excel program will compute the Calculated Weight before Digestion, Percent
Difference, Recovery Percent and Dilution Factor.

9.2 Troubleshooting

9.2.1	MARS-5 System: Monitor the pressure and temperature during the digestion process.
If the expected temperature or pressure is not maintained during the digestion,
investigate the cause, and consult the group leader to determine if re-digestion is
necessary.

9.2.2	Follow instructions in Appendix B or the MARS-5 instruction manual if recalibration of
the pressure sensor or temperature sensor is required. The pressure sensor calibration
constant is 4315-4316-0621-0623-6637-2241.

10. Data and Records Management

Calculations

10.1	Acid Weight = desired volume x density

Optima Nitric acid weight = 9 mLx 1.40 g/mL = 12.60 g
Optima Hydrochloric weight = 3 mLx 1.18 g/mL = 3.54 g

10.2	Calculated Weight before Digestion: The Excel program will add the vessel weight, the
sample weight and the acid weight to give the expected weight before digestion in grams.

10.3	Percent Difference: The Excel program will divide the weight after digestion by the calculated
weight before digestion and multiply by 100 to give a percent difference.

10.4	Dilution Factor: The Excel program will add the sample weight and the acid weight adjusted
for specific gravity, and divides the result by the sample weight to obtain the dilution factor
used in data calculations.

Records Management

10.5	The digestion data will be stored on the individual analyst computer and on a designated EPA
shared drive. Additionally, hard copies of the digestion data bench sheets will be placed in
the Tire Crumb digestion binder located in CHL-43. Sample preparation and digestion notes
not included on the digestion bench sheets will be taken in a research notebook maintained
as per ORD requirements in ORD PPM 13.2

11. Quality Assurance/Quality Control

11.0	Reagent Blank (RBLK): A reagent blank will accompany each digestion batch of 24 or fewer
samples. The mixture of acid reagents (Section 9.1.0) will be used. The reagent blank is used
to track potential contamination during sample preparation and extraction. The reagent
blank is treated as a regular sample. If a sample is filtered before analysis, then a blank will
also need to be filtered to assess if the filter is contributing any contamination.

11.1	Laboratory and Field Blank (LBLK and FBLK):Two matrix blanks will be prepared prior to
field-sampling, but the Laboratory Blank will remain in the lab and will not travel to the
sampling site, while the Field Blank will travel to the field sampling site. In an ISO 5 Class 100
Clean Lab, acid-cleaned plastic forceps will be used to place a wipe sample into an acid-
cleaned 50mL flat-bottom polypropylene sample tube.

11.2	Laboratory Control Sample (LCS): Another matrix blank will be prepared and to this, will be
added 250 |al of the custom spike standard solution (Section 8.5) before digestion. The LCS
results will be used to determine if the laboratory can perform the analysis in a clean matrix.
Acceptable recovery range of this sample is 65-125%.

11.3	Field Control Sample (FCS): This sample is similar to the LCS sample in 11.2, but it travels to
the field. A 250 |al aliquot of the custom spike standard is added to the ghost wipe.

11.4	Standard Reference Material: A standard reference sample (if available for the sample matrix
type to be analyzed) should be included with each batch of samples processed. As of now
there is no standard reference material available for wipes.

11.5	Digestion Percent Difference: The percent difference between the weight after digestion and
the calculated weight before digestion should not exceed 10 %. If the percent difference does
exceed 10%, investigate the reason, correct, and re-digest the sample.

11.6	Pressure and Temperature Monitoring for the MARS-5 system: Examine the pressure and
temperature monitoring graph. If the pressure or temperature deviates from the set point by
15 % or more after ramp up and before the end of the digestion, investigate the problem,
and consult the group leader to determine if re-digestion is necessary. Determine if the
sample in the monitoring vessel was the cause and if not, the microwave may need
recalibration (refer to Appendix B and C).

Microwave Extraction Programs

Two microwave accelerated reaction systems MARS-5 are located in CHL-25 laboratory. The digestion
programs use a ramp to temperature approach and are available on both systems. Depending on the
number of vessels used, the analyst should choose the appropriate ECBTRC- method.

1. Program Name: ECBTRCW-1

Max Power = 400W
% Power = 100%

Ramp = 15 minutes
Pressure = 0 psi
Temperature = 200 °C
Hold Time = 15 minutes
Number of Vessels = 1 to 4

2. Program Name: ECBTRC-2

Max Power = 800W
% Power = 100%

Ramp = 15 minutes
Pressure = 0 psi
Temperature = 200 °C
Hold = 15 minutes
Number of Vessels = 5 to 8

3. Program Name: ECBTRC-3

Max Power = 1600W
% Power = 100%

Ramp = 15 minutes
Pressure = 0 psi
Temperature = 200 °C
Hold = 15 minutes
Number of Vessels = 9 to 12

Appendix B

Quality Control Test for MARS-5 Vessels and Sensors

This quality control test should be performed only if deemed necessary.

1.	Place 50 mL Dl water in the control vessel (XP1500+, or HP500+), and assemble as you normally do
with the temperature and pressure sensors attached.

2.	Place the control vessel in the turntable and connect the sensors. (No other vessels are run during
this test.)

3.	Go into the CEM Directory and load the preprogrammed "QC ESP/EST" method.

4.	Allow the method to run, observing the temperature and pressure readings. When you get to stage
5, record the temperature once the pressure has begun controlling at 200psi. The temperature
should be 200°C +/- 10C at 200psi. If it is not, either the temperature or pressure sensor is out of
calibration.

5.	Allow the vessel to cool to < 50°C. Measure the volume of water remaining in the vessel. If you put
50mL in, you should get 50mL back out. If the volume is < 50mL, then there is a leak.

Note that a vessel can be leaking and still pass the QC test (200psi = 200°C). Look for volume loss
instead.

6.	If the QC test fails (i.e., you do not get 200°C +/-10C at 200psi), then recalibrate the temperature
probe and repeat the QC test.

Appendix D
Procedure for Cleaning Vessels

This cleaning sequence has been determined to be adequate to minimize contamination in glass,
polyethylene, polypropylene or PTFE vessels.

1.	Prepare cleaning solution by adding a small amount (approximately 5 mL) of concentrated
Citranox (Alconox Inc.) liquid soap to a tub of reverse osmosis (RO) water (~6 L). Remove all
markings and residue from vessels using a designated lab brush or methanol if necessary.
Submerge vessels in soap solution and allow to soak for a few minutes.

2.	Clean the vessels with a lab brush. Rinse three times with reversed osmosis water and one
last time with deionized water.

3.	Place the vessels in an acid bath containing 10% (v/v) Trace-metal clean concentrated HN03
in Dl water, and let them soak overnight (and up to 48 hours).

4.	Remove vessels, rinse three times with deionized water.

5.	Allow vessels and lids to air dry (open end down) on a clean surface.

6.	This step applied only to the XP-1500 microwave digestion vessels that already went through
the above cleaning steps.

Use the Optima grade acid to prepare 1 liter of 10% Nitric acid.

-	Fill the vessels approximately half way with acid (~50 mL) and secure the lids. Don't forget
to place a safety membrane in the vent cap.

-	Place the vessels in the carousel and microwave the solution using extraction program
ECBCM-1, -2 or -3 (Appendix E) depending on the number of vessels.

7.	After cooling to room temperature, pour the nitric acid solution back into the Teflon cleaning
solution container. Rinse vessels and caps three times with deionized water, and allow to air
dry.

8.	All sample bottles and microwave vessels should be capped and stored in sealable plastic
bags or plastic containers to prevent contamination.

9.	Label bag or container with the cleanup date and batch number.

When cleaning polyethylene conical tubes with external graduation, soaking in an acid bath is not
recommended as the material used to graduate the tubes can be removed upon contact with acid
and therefore can become a source of contamination.

-	Remove the caps and let the tubes stand in the Styrofoam base.

-	Pour Dl water into each tube and secure the caps. Let the sealed tubes soak for a few
minutes, shake well and discard the water. Repeat this step two more times.

-	Fill each tube with 10% nitric acid and let sit overnight or at least twelve hours at room
temperature in the Styrofoam container with their lids on.

-	The next morning, the sealed tubes are reversed to give the cap a chance to get in contact
with the acidic solution. Leave the tubes in that position for at least four hours.

-	Pour the acid content into an acid cleaning bottle.

-	Rinse tubes and lids several times with deionized water and allowed to air dry.

-	Cap the tubes, place them back in their Styrofoam base and keep them seal until usage.

1.0 Scope and Application

Inductively coupled plasma mass spectrometry (ICPMS) is a widely accepted analytical tool for trace and ultra-
trace elemental analysis. It has been the technique of choice for accurate and precise measurements needed for
today's demanding applications.

In ICPMS, an inductively coupled plasma (a gas consisting of ions, electrons, and neutral particles) is formed
from argon gas under an intense electromagnetic field. The plasma is used to atomize and ionize the sample
matrix. The resulting ions are then passed through a series of apertures into the high-vacuum mass analyzer.
Isotopes of the elements are identified by their mass-to-charge ratio (m/z), and the intensity of a specific peak in
the mass spectrum is proportional to the amount of that isotope (element) in the original sample.

Because of the enormous number of possible interferences, the ability to isolate analytes from interfering species
is critical to any analytical ICPMS instrument. Double-focusing magnetic sector field ICPMS, often called high-
resolution ICPMS (HR-ICPMS), provides a straightforward solution to most of the polyatomic and isobaric
interferences by separating the analyte of interest from its interfering species. EPA's National Exposure Research
Laboratory (NERL) purchased an HR-ICPMS instrument, the Element 2 (E2), from Thermo Finnigan (now
Thermo Fisher Scientific, Waltham, MA). This instrument has been installed in NERL's Class 100 clean lab.

This standard operating procedure (SOP) is intended to provide the following information:

•	Descriptions of various components of E2 and its control software (v3.0)

•	The basic operational settings of the E2

•	Autosampler control procedures

•	Procedures to prepare reagents and calibration standards

•	Procedures for verifying performance measures of the E2 on a daily basis

•	Instructions for preparing various logs

•	Instructions for setting up a sequence for automated use of the instrument with QC checks

•	Need-based instrument conditioning and maintenance procedures such as changing recirculating fluid, establishing
mass calibration, and changing the entrance slit assembly

•	Instructions for flagging sequence results using the "ICPMS Data Flagger" application

2.0 Summary of Method

2.1	This SOP is intended for either (1) analysis of SEAS slurry samples after preparing samples according to
SOP-WDE-08-01 Standard Operating Procedure for Preparation of SEAS Samples for HR-ICP-MS
Analysis, or (2) analysis of ambient air particles collected on Teflon filter media after aqueous or dilute
acid-phase extraction (SOP# ECAB-114.0 "Standard Operating Procedure for the Three-Stage Extraction
of Filter Media for Ion Chromatography and High Resolution Inductively Coupled Plasma Mass
Spectrometry") and (3) ECAB 149.0 "Processing Hydraulic Fracturing Field Samples for Trace Metal
Analysis".

2.2	An internal standard is added on-line at the time of analysis using a second channel of the peristaltic
pump and a low dead-volume mixing manifold.

2.3	Data acquisition and evaluation parameters for this method have already been established in the clean lab.
Appendix 1 lists all parameters for the multi-elemental method used in this SOP.

2.4	This method employs the ASX-510 autosampler (CETAC Technologies, Omaha, NE) for analysis.

4.0 General Safety Considerations

4.1	To avoid personal injury or damage to the instrument, do not perform any servicing other than that
contained in the E2 hardware manual unless you are qualified to do so.

4.2	High voltages capable of causing personal injury are used in the instrument. Some maintenance
procedures require that the mass spectrometer be shut down and disconnected from the power before
service is performed.

4.3	Do not operate the mass spectrometer with the top or side covers off. Do not remove protective covers
from printed circuit boards. Safety labels are used on the instrument to show potential safety risks. Read
the labels carefully.

4.4	Ensure that you read and understand the hazards of the chemicals used.

4.5	Refer to MSDSs for information on the hazards and toxicity of specific chemical compounds and for the
proper handling of compounds, first aid for accidental exposure, and procedures for remedying spills or
leaks.

5.0 Interferences

E2 can be operated to achieve mass resolutions, R (Am/m), of up to 10,000 by means of entrance and exit slit
assemblies. By varying resolution settings, it is possible to tailor an analysis in such a way that each isotope is
analyzed at a resolution that will enable it to be fully resolved from any interference with minimal compromise of
its sensitivity.

Table 1 lists common interferences on the most abundant isotopes that require resolution settings (provided list is
not complete). If the needed R value is between 300 and 4000, the MR setting is used for data acquisition. If R is
in the 4000 to 10,000 range, the HR setting is recommended. If the calculated R value is over 10,000, that
interference cannot be resolved by E2. Under such circumstances, an alternative isotope and/or interference
correction equation, or combination of both, must be applied.

8.0 Analytical Standards and QA/QC Solutions
8.1 General Guidelines

8.1.1	Always use reagent water for making analytical standards and for sample preparation.

8.1.2	Any acid concentration must be less than 4% for ICPMS analysis to minimize damage to the
interface and to minimize isobaric molecular interferences.

8.1.3	The concentrations of dissolved solids in analysis solutions should be less than 2% to protect the


-------
HR-ICPMS Analysis
D-EMMD-PHCB-042-SOP-03

Page 9 of 52

sample interface on the instrument. Higher concentrations may plug the sample cone orifice.

8.1.4	Know your sample. Protect the SEM from high chemical concentrations (high ion currents).
SEM suffers from fatigue after being exposed to high ion currents. This fatigue can last from
several seconds to hours depending on the extent of exposure. During this period, response
factors are constantly changing, which causes instrument instability that invalidates the
calibration curve, thereby invalidating all associated sample results. For instance, sodium
bicarbonate (NaHCCh) sample matrix is known to cause this problem.

8.1.5	Use acid-cleaned sampling tubes and containers for standards and samples using the following
procedure:

1.	Rinse in reverse osmosis (RO) water, and then fill with RO water.

2.	Let sample containers/tubes leach in RO water for 1 hour.

3.	Empty tubes and fill with 4% HNO3 (v/v) + 2% HC1 (v/v) solution.

4.	Place filled tubes in a convection oven at 90 °C for 3 hours.

5.	Let tubes and contents cool, and then pour out the acid solution (save and reuse this acid
solution mix).

6.	Fill tubes with reagent water for 1 hour.

7.	Pour out the rinse solution, and triple rinse with ultra-clean reagent water. Store tubes
completely full with reagent water until use.

8.	Tubes do not need to be completely dry before use.

8.2	Chemicals and Reagents

Concentrated analytical-grade Baseline nitric and hydrochloric acids (SeaStar Chemicals Inc., Sidney,
BC, Canada)

High Purity primary standard solutions

Reagent water (> 18.2 MQ-cm) for making calibration standards
Liquid argon, high-purity grade (99.99%)

8.3	Preparation of Reagents and Analytical Standards

8.3.1	Reagent Blank

Prepare 0.2% (v/v) nitric acid and 0.1% (v/v) hydrochloric acid solution by adding 4 mL of conc.
nitric acid and 2 mL of conc. hydrochloric acid to a 2-L Teflon bottle and make up the volume
with reagent water.

8.3.2	Tune Solution

The tune solution contains elements representing all of the mass regions of interest, thereby
allowing verification that the resolution and mass calibration of the instrument are within the
required specifications. The solution is also used to verify that the instrument has reached thermal
stability. Use individual primary standards from High Purity Standards (Charleston, SC, USA) to
make a stock tune solution according to procedures in Table 2, and then dilute it 100 times in 1%
HNO3 to create a working tune solution of 1 ppb.

8.3.3	Autosampler Rinse Solution


-------
HR-ICPMS Analysis
D-EMMD-PHCB-042-SOP-03

Page 10 of 52

Prepare 0.4% (v/v) nitric acid and 0.2% (v/v) hydrochloric acid solution by adding 4 mL of conc.
nitric acid and 2 mL of conc. hydrochloric acid to a 1-L Teflon water bottle and making up the
volume to 1000 mL with reagent water.

8.3.4 Stock Solutions

Depending on availability, Stock Solutions A, B, and S are made from certified primary standard
solutions procured from High Purity Standards. Use acid-washed, wide-mouth Teflon bottles to
make stock solutions. Table 3 summarizes the procedure to make all stock solutions. Appendix 5

10.0 Basic E2 Instrument Operations (Startup, Standby, and Shutdown)

The procedure for starting an analysis is detailed below in sections 10.1 and 10.2. At the end of analysis, E2
should be taken to standby (section 10.3). Standby means the status of all components is known and the
components are okay. When E2 is in Standby, only the plasma is switched off. The shutdown procedure (section
10.4) should be performed only after consulting the laboratory manager. Shutdown status implies the E2 system is
vented and the power for all components, including the front-end computer, is switched off.

10.1 Bringing the E2 Instrument from Shutdown to Standby

1.	Switch on the main power for the instrument (switch S1 on back of unit in Figure 3).

2.	Turn on the argon gas so the overall head pressure >110 psi. Turn on the recirculating chiller unit
(the chiller should remain on unless performing maintenance that specifies otherwise - see section
12.1).

3.	Turn the key-operated switch (status panel) to ON position to start the high vacuum (HV) for the
backing pump and the four turbo pumps.

4. Switch on the power for the electronics and front-end computer (switch S2 on front of unit in Figure

3).

Note: It is recommended that the front-end PC be rebooted using the RESET button on the status display
panel. The instrument is in standby position when the high vacuum reaches 10 7 mbar. This will take
approximately 24 h.

10.2	Bringing E2 from Standby to "Ready to Measure"

1.	Open and fill in the Daily Startup Log (see Appendix 3 .1, and refer to section 12 for the complete
procedure). Once checks are passed, proceed to the next step.

2.	Connect the drain line of the cyclone spray chamber to the peristaltic pump head. Connect sample
lines if needed.

3.	Open the instrument task window, and switch on the plasma by activating the PLASMA ON button.

4.	When the status box signals "Ready," switch on the high voltage by clicking the HV button in the
tool bar of the instrument task window.

After 2 hours of thermal equilibration, the instrument is now ready fortuning.

10.3	Bringing E2 from "Ready to Measure" to Standby

1.	When measurements are finished, rinse the sample inlet for 5 min by inserting the sample inlet in a
0.2% acid rinse solution.

2.	Go to the instrument task window and switch off the plasma by clicking the PLASMA OFF button.
Wait until the stop sequence is completed.

3.	If the peristaltic pump was not stopped, stop it manually by clicking "Peri.pump on/off." Open the
brackets at the peristaltic pump and release the tubing.

4.	Switch off the high voltage by clicking the HV button in the instrument tool bar. If the instrument is
in continuous daily usage, it is better not to switch off HV.

10.4 Bringing E2 from Standby to Shutdown

This operation should be done only when a power shutdown is announced. Always consult the laboratory
manager before shutting down the instrument.

1.	Turn the key switch of the status panel counterclockwise. This turns off the pumps.

2.	Turn off switch S2 (front).

3.	Turn off switch SI (back).

4.	Turn off the recirculating chiller and argon gas lines.

11.0 Autosampler Control

An ASX-510 autosampler is connected to the host computer and controlled through the E2 software. The ASX-
510 is equipped with one built-in sample tray (Rack 00) capable of holding ten 50-mL polypropylene sample vials
and four removable trays (Racks 01-04) that are each capable of holding up to sixty 15-mL polypropylene sample
tubes (see Figure 4). This SOP covers only the required procedures for operation of the ASX-510. Refer to the
autosampler operator's manual for detailed procedures for installation, usage, maintenance, and troubleshooting.

Rack 04

-*	Autosampler probe

Figure 4. ASX-510 autosampler (source: Cetac web site).

Check the following before you operate the autosampler via the host computer:

1.	Ensure the autosampler power is on. The green LED indicator (above the flow-through rinse station) stays lit
while the power is on. Also make sure the RS-232 cable is securely connected at both ends.

2.	Ensure the rinse station is properly connected. No air bubbles should be visible in the rinse uptake tubing
before you run samples. The rinse solution container should be filled with rinse solution, and the drain line of
the autosampler should be connected to the rinse collection tank.

11.1 Manual Operation

HR-ICPMS Analysis
D-EMMD-PHCB-042-SOP-03

Page 17 of 52

The bottom left portion of the instrument task window displays the ASX-510 autosampler graphical user
interface (GUI), as shown in Figure 5. The RR/PPP format, where RR refers to the rack number and PPP
refers to position numbers, is used for moving the autosampler probe to a specific location. Selecting a
spot with the mouse creates a red square around the sample. Next the GO TO button at the top of the GUI
is pressed, which moves the sampler probe to the selected location and starts sampling. At this point, the
box turns green.

The HOME button at the top of the GUI returns the autosampler probe to the home position (does not
sample). Pressing the WASH button pumps rinse solution into the flow-through rinse cell. The sampler
probe is dipped into the rinse cell so it gets washed externally while rinse solution is sampled as well.

11.2 Automated Operation

Vial positions have to be used in connection with the Sequence Editor to operate the ASX-510 in a fully
automated fashion (section 12 covers this in greater detail). Adhere to the following vial positions while
building an analytical sequence so that available sequence templates can be manipulated easily for new
sequence setups.

Rack 00:

Position 1 (00/001): Rinse solution
Position 2 (00/002): Tune solution

Positions 3-8 (00/003-00/008): Calibration standard solutions


-------
HR-ICPMS Analysis
D-EMMD-PHCB-042-SOP-03

Page 18 of 52

Position 9 (00/009): Check sample

Rack 01: Positions 48 and 49 are used for placing SRM samples. Other positions are generally left
unused.

Racks 02-04: Any number of these positions can be used depending on the number of samples. For
convenient sequence building, the last two positions of every row are left empty (see section 12.6). Once
sample vials are loaded, make sure the arrangement is correctly defined in the Sequence Editor.

12.0 Routine Operational Sequence of E2

The following sequences of steps assume that the instrument is in standby mode. If not, follow the steps in section

10 for bringing the instrument from shutdown to standby.

12.1 Getting Ready

1.	Open the Daily Startup Log (Appendix 3.1). Fill in the form as you go through the following steps.

2.	Check two argon gas tanks (located in the XRF laboratory in room D455-A). Check the liquid argon
level indicators and output pressure in the gas cylinders. At least one cylinder should have greater
than 50% Ar and approximately 200 psi output pressure. The secondary control (mounted on the
wall) is set to output 115-140 psi to the instrument.

Special note: In case of a limited argon gas supply, the slit assembly and skimmer valve assemblies can
be controlled by an additional gas line such as nitrogen. (Refer to p. 4-11 of the E2 hardware manual for
configuration). We do not recommend this setup unless the situation is unavoidable.

3.	Check the recirculating chiller unit located next to the gas tanks. Write down the display temperature
(should be ~ 18 °C) and water level.

4.	Make sure the backup power supply unit, located in the service corridor, is operational. No warning
messages should be displayed. Write down the percentage of backup power (usually 80%).

5.	Check the system status panel of the E2 (top left). Make sure you see green LEDs as shown in Figure
6 on the following: TORCH IN POS, ARGON PRESSURE, INTERFACE COOL, HV
ELECTRONICS, INTERLOCK HOOD, BOARD CHECK, HV, FV, TP A, TP B, TP C, TP D, and
FORE PUMP. If not, go to section 15 for troubleshooting references.

6.	Start the host computer and log on as "SEAS". Currently, the SEAS user group is set up for executing
multi-elemental analysis of fine PM samples in a 0.2% nitric acid and 0.1% hydrochloric acid (v/v)
matrix. Leave the password space empty and click LOGIN.

7.	Open the folder labeled Thermo ELEMENT on the desktop.

8.	Double click Network Processor, which will establish communication
between E2's front-end computer and the host computer. This will
automatically open and activate the EXECUTIVE task window.

9.	Select EXECUTIVE task window, if not selected already, and click the
CUSTOMIZE menu.

10.

In AUTOSAMPLER settings, the ASX-510 should be selected and COM2 enabled.

If any settings differ, notify the laboratory manager and correct it.

12.	Connect sample (autosampler end) and internal standard (IS) line outlets to E2's first and second
peristaltic pump channels using orange-green peristaltic tubings. Combine the outlet of tubings using
a T-joint. Connect the perpendicular end of the T-joint to the nebulizer with green-coded (100 uL)
capillary.

13.	Connect the cyclone spray chamber drain to the peristaltic pump using gray-gray polypropylene
tubing, and connect its outlet to the ICPMS rinse collector underneath the E2"s sample tray.

14.	Set the autosampler and IS sample inlet lines to draw reagent blank (0.2% HNOa and 0.1% HC1
solution).

12.2 Igniting Plasma

1.	Select the Thermo ELEMENT folder on the desktop and click the INSTRUMENT icon. The
instrument task window is shown in Figure 7.

2.	Start high voltage (HV) if not already on (see top left red circle in Figure7).

3.	Under the Instrument dropdown menu, select "peristaltic pump turn c.w.," and then "peristaltic
pump" on. E2"s peristaltic pump should then rotate clockwise. Adjust tension knobs in the pump such
that solutions from sample and IS lines flow smoothly. Also ensure that the cyclone continuously
drains.

4.	Start Plasma by clicking the ON button in the plasma schematic (top right quadrant in the instrument
task window (top middle red circle in Figure 7). Plasma will start after approximately 5 mill. The
following sequence should be observed during the ignition process: interface pump starts, RF
generator starts, plasma appears, and sample gas slowly ramps up to set value.

Caution: Once the RF generator starts and "Forward Power" is displayed on the front status panel of the
E2, plasma should have been lit. Otherwise, a condition called "Cold Plasma" has developed which can
harm the torch. Under this circumstance, press the RF ON/OFF button on the status display panel to turn
off RF power, and terminate the startup sequence by pressing the STOP button in the plasma schematic

(see Figure 7).

5.	Record the High Vacuum pressure prior to plasma ignition.

6.	After plasma ignition, fill in the fore and high vacuum readings in the Daily Startup Log (Appendix
3.1). Note: Typically, fore vac is on the order of 10"4 mbar and high vac is ~ 1.7 x 10"4 mbar. If the
vacuum readings differ significantly, contact the laboratory manager.

At this point, the Daily Startup Log should be completed and the E2 successfully started. Next follow the

instructions below fortuning the instrument.

12.3 Tuning the Instrument

1.	Open the Tune task window. The most recent tune file (with extension .tpf) automatically loads.
Otherwise, find an earlier day's file and load it (older tune files are stored in folder
"C:\Element\user\SEAS\Tune ParametersV').

Note: If there have been hardware changes such as new cones, torch, or slit assembly, an extensive tuning

will be required. Detailed tune operations can be found in chapter 2 of E2 manual version 3.

2.	Press  to open the Scan List menu (alternatively, click the yellow spectrum in the tool fT
bar), and load THERMOLRTUNE.SCL. Press START SCAN (green button in the tool
bar). You should now see Li, In, and U panes active. Make sure you are still

sampling reagent blank through both channels.

3.	Let the instrument warm up for approximately 30-60 min.

4.	By default, tune parameters are locked for all resolutions. Make sure that "All Parameters Resolution
Dependent" under the Tune menu is not enabled.

5.	Set the autosampler probe (sample line) to the tune solution (refer to section 11), normally placed at
position 00/002 of the ASX-510 autosampler. Select position 00/002 in the autosampler GUI
(instrument task window) and click GO TO. The IS sample line should still sample reagent blank.
The take-up time of tune solution by the ASX-510 setup is approximately 4 min.

6.	Stop the scan and restart the LR tune for intensity and stability.

7.	Check signal stability and intensity for Li, In, and U. The instrument specification (spec) for In is one
million cps. If the performance is not satisfactory, check and adjust the sample gas (by opening slider
controls with a right mouse click on the gas-flow box) and torch Z positions (in torch position box). If
the performance is satisfactory, click Stop Scan (red square). Click the Save As button in the tool bar
and create today's tune file. A suggested format is yourlastname_ddmonthyyyy (e.g.,
pancras_ 12 April2008).

8.	Next perform MR tune for optimum peak shape and resolution. Open the scan list again and select
Thermo_MR_Tune_Fe_ArO_Resolution.scl. Start the scan. Lower the y scale so the 56Fe peak can be
seen. The current resolution for MR is displayed at the top left of the intensity box. You may need to
slightly adjust the Focus Quad 1 (FQ1) of the MR lens to achieve optimum resolution. For MR, the
spec is 4000.

9.	Save the tune parameters and proceed to HR tune.

10.	Open the scan list and select Thermo_HR_Tune_K_ArH_Resolution.scl. Tune for high-resolution
lenses.

11.	If the mass separation between K39 and ArH38 is not satisfactory, adjust FQ1 of the HR lens such
that an R value of 10,000 is achieved.

12. Once tuned, save the tune parameters under today's tune file name.

At this point, E2 is ready for performance evaluation.

4 Performance Evaluation

1.	Open the Sequence Editor task window. Make sure ALM on the Actions menu is enabled. A mass
calibration is deemed valid when mass drift values do not exceed 500 ppm. The E2 operator can see
current drift values by going to Executive/Log files/EDAC.

2.	Use the Open button in the tool bar of the Sequence task window to open the sequence named "Daily
Performance". The sequence settings can be viewed in two ways: spreadsheet (Figure 8) and GUI
(Figure 9). The spreadsheet is recommended for setting up or editing and the GUI for verifying and
running a sequence.

12.5	Sequence Start—Mass Offset

Check mass offsets every time a new analysis sequence is started. Generally, mass offset values are

method specific. Set the autosampler probe (sample line) to rinse for a few minutes to clean the sample

lines, but use a mid-level calibration standard to check the offsets.

1.	Open the Sequence Editor task window, and make sure ALM on the Actions menu is enabled. From
the File menu, open the file "slurry_offset.seq".

2.	Go to spreadsheet view, and type or browse by double-clicking the cell for the analytical method for
which method offsets are to be computed (for SEAS sample analysis, the method is
"MultiElement_SEAS_Aug2008"). Type or browse for the current tune file.

3.	Click the Start Flag icon in the top center of the GUI page. This action will open a Run task window
at the bottom of the Sequence task window. Enable the "Acquire" and "Evaluate" boxes if not already
enabled, then click Run. Click "Continue" on the pop-up menu.

4.	After the first sample is analyzed, a pop-up screen will ask if you want to continue to the next sample.
Press the Stop sequence.

5.	Select the sample that was just analyzed, and click the Results task window icon in the menu bar. The
Results task window will open and display the results for the run just completed. Under the File menu
in the Results window, click "Update the offset values from the results into the active method file"
and press "OK".

6.	Close the Results task window, and start the sequence again. Now monitor peak positions of the
second sample in the Show Task window while the sample is being analyzed. This provides visual
proof that the centroid of a mass peak is now centered within the chosen mass range.

At this point, mass offsets are computed and inserted into the analytical method. Next an analytical

sequence is created from an existing sequence. This template is specific for the ASX-510 autosampler.

12.6	Sequence Start—Analysis

1.	In the Sequence task window, open the sequence "Slurry_sample_Seq_Template" by choosing
File/Open as Template/.

2.	Go to the spreadsheet view and change sample names and method files as needed. Follow Table 7 to
fill in the needed columns/cells. You can select and drag cells to fill all of the rows in a column.

3.	Standard files are named WSO, WS1, WS2, WS3, WS5, and WS6. Corresponding standards
concentration tables are created and stored in C:\Element\user\SEAS\
Standards\folder.

4.	This sequence has autosampler positions, so therefore the sequence automatically starts when the Run
button is pressed.

13.0 Need-Based Procedures

13.1 Mass Calibration

Mass calibration leads to correct identification of mass numbers of the mass peaks of interest. The mass
calibration can be executed either manually from the Instrument task window or automatically from the
Sequence task window. Only the automatic method is outlined in this SOP.

The Mass Calibration task window (see Figure 12) is used to display the data acquired for the purpose of
mass calibration. There are three display panels: mass spectrum (upper), MDAC vs. mass calibration
curve (lower left), and second derivative diagnostic curve (lower right). The second derivative curve
should be viewed carefully as large spikes in the curve indicate poor calibration. A smooth "L" curve
shape with small spikes indicates a good calibration.

Load the calibration sequence file Thermo Automasscal.seq (located by default in directory
C:\Element\SEAS\data\). This sequence contains six samples, each with a unique method to cover all
three resolutions with two different mass window settings (wide and narrow).

The six samples in this sequence are named LRWide, LR Narrow,

MRWide, MR Narrow, HR Wide, and HR Narrow and are designated as
MCAL samples. Click the Reset icon in the tool bar and select 'All" from the dialog box.

Choose the current tune file for all six analyses.

Click the Start icon in the tool bar to check and start the sequence. This action will open the >
acquisition window. Because no reports are required from the auto mass calibration sequence,
all output check boxes should be cleared. Make sure the boxes "Acquire" and "Evaluate" are
checked!

Click the Run button in the acquisition
window. After an automatic check, the
following message appears: "Following
sample has no autosampler position." Click
Continue in the pop-up screen. Note: The
check box "Do not show this box again" in
the pop-up window remains unchecked so
that an analysis can be verified for accuracy
once it is completed.

Open the Mass Calibration task window. After verifying the information in
section 13.1.1 (diagnostics of LR calibration), press the Gears button, click
"yes" to "delete current calibration" and then Files>Save and return to the Sequence Editor.

Continue the sequence until MR Wide and Narrow samples are analyzed. Then click Stop and go to
the Mass Calibration task window. After verifying the information in section 13.1.1, save the file and
return to the Sequence Editor.

10. Continue HR Wide and Narrow. Save.

11. The mass calibration is now completed. Go to section 13.1.2.

13.1.1 Diagnostics of a Mass Calibration

1.	In the tool bar of the Mass Calibration task window, click on the "Open Analysis" icon to
show the browsing dialog.

2.	Open subdirectory Thermo Automasscal. Find the acquired file for the latest (just completed)

Diagnostic Curve forLR Calibration

Figure 13 shows a typical LR 2nd deriv. diagnostic curve. Notice the following features in the
figure:

•	There are two spikes at low mass: the Li isotopes 6Li and 7Li seem to be overlapping in the
LR plot, which is normal.

•	There is a large gap between m/z 23 and 45: this causes spiking for both isotopes, which is
normal and can be ignored.

•	The large spike at m/z 45 is normal: this is caused by the inaccuracy at m/z 45 due to
polyatomic ions (for example 12C16C>2H or 14N216OH) at the same nominal mass as Sc.

If you see any incorrect identification of peaks go to section 13.1.2 to fix it.

Diagnostic Curve for MR Calibration

Figure 14 shows a typical MR diagnostic curve. The following should be noted from this figure:

•	There are two spikes at low mass: the Li isotopes 6Li and 7Li seem to be overlapping in the
plot, which is normal.

•	There are more points at lower masses: more calibration points are added in the low mass
range to ensure mass accuracy.

•	The biggest spike is 238U160 at m/z 254: the counts for 238U160 are low in MR so its spectral
peak is not well defined. This leads to a higher deviation than for other masses, which is
normal.

If you see any incorrect identification of peaks go to section 13.1.2 to fix it.

Diagnostic Curve forHR Calibration

Figure 15 shows a typical HR diagnostic curve. In this figure, notice the following:

•	There is a large spike at low mass: only 7Li is calibrated in HR as the 6Li count rate is low.

•	The spike between 7Li and 1 IB is normal in HR.

•	There is some spiking around m/z 80: to ensure an accurate calibration for As and Se, the Ar
dimer background interferences at m/z 76, 78, and 80 are used as mass calibration points in
HR. As these masses are closely spaced, some small spikes may be seen, which is normal.

If you see any incorrect identification of peaks go to section 13.1.2 to fix it.

13.1.2 Check All Masses

1.	Click the Manual Calibration icon in the Mass Calibration task window. It will display jjsjra*
a list of calibrated masses.

2.	Select the first entry in the list. Double click it to zoom to it in the spectrum field. The mass
range around the calibrated mass is displayed. The mass marker should be centered on the
peak. If the mass is correctly calibrated, move on to the next entry.

3.	If the mass marker is not correctly assigned (not centered on the peak), delete this jjjjj
reference point by clicking on the Delete icon.

4.	To assign a new reference point, center the mouse over the peak in the spectrum and double
click it. A Calibration Mass dialog appears as shown in Figure 16.

5.	Select the correct isotope/interference from the Suggestions list. (Note: Only elemental peaks
are initially displayed. To display the interferences, the option box at the bottom of the dialog
must be activated.)

6.	Click on Add to add the new reference point to the calibration, and click Save to save
the new calibration.

7.	Check all masses in the list and remember to save the file at the end.

The most commonly miscalibrated masses are between 6 and 70 amu. Comparing isotope ratios

or widening the display task window will aid in the identification of problem isotopes such as the

following:

•	6Li/7Li: Use the natural abundance Li isotope pattern, 7.5/92.5, to identify the Li isotopes.

•	28Si: The 3sSi peak is to the left of the two interfering polyatomic species.

Page 32 of 52

•	16C>2: The count rate for 16C>2 at m/z 32 is high, often close to the detector maximum of
5.0* 109 cps.

•	45Sc: The 45Sc peak is to the left of the interfering polyatomic species.

•	69Ga: The 69Ga peak is to the left of the interfering Ba2++ species. A high Ba2++ signal
indicates non-optimum tuning.

Reinitialization of mass calibration may be required if E2 was shut down lately. This process
starts using a default mass calibration, saved in the host computer, and eventually builds a new
valid calibration. E2 users should consult the laboratory manager if such a need arises.

Perform the following steps to reestablish mass calibration:

1.	Open the default masscal file, and run the LRWide analysis.

2.	Delete the old calibration, and save the new one.

3.	Re set MR and HR calibrations.

4.	Start the MR samples.

5.	Fix mass peaks as needed.

6.	Save and proceed to HR.

7.	When done with the masscal, save the HR_Narrow as your new default file.

13.2 Change Water in Recirculating Chiller

Note: Use RO water only; do not use DI water. It is recommended that you take RO water from D461-B
(acid clean lab). A kit with all needed tools is placed on top of the chiller unit.

1.	Turn off the chiller.

2.	Disconnect the top hose from the chiller with a screwdriver. Clamp the hose to the drain pan and cap
the valve on the back of the chiller.

3.	Open the reservoir on top of the chiller, unscrew the cap, and place a funnel into the container.

4.	Turn on the chiller.

• Chiller may get loud periodically.

5.	Turn off the chiller.

6.	Pour the drain pan contents into the sink.

7.	Reconnect the recirculating hose.

8.	Fill reservoir to fill line as shown.

9.	Turn on the chiller and ensure there are no leaks.

•	Should start to recirculate water to the pan.

•	Start filling water through funnel to flush the

system.

13.3	Change Entrance Slit Assembly

Locate the following tools and accessories before beginning the procedure:

•	Torque wrench (comes with the E2 instrument)

•	Half-cut 1-mL pipette tip to hold screw

•	Flat-type long-stem screwdriver

•	Lint-free paper towels

•	Powder-free vinyl gloves

Follow step by step the document titled "Slit_exchange_info_from_E2_Maintenance_
Course.pdf," published by Thermo Fisher and found in the laboratory manual holder or in the host
computer in the My Documents folder. After completion, turn on the E2 and let it pump down overnight.
Make sure the high vacuum is in the order of 10"7 mbar before using the E2 or activating the High Voltage
on the magnet.

Special note: Perform a mass calibration after a new entrance slit assembly is in place.

13.4	Maintenance of Sample and Skimmer Cones

The sample and skimmer cones require cleaning and eventually replacement after prolonged usage. It is
important not to damage the tips of the cones during the cleaning process because the ion extraction will
be degraded. Follow the steps below to clean them:

1.	To remove the sample cone, line up the cone removal tool with the cone locking ring and unscrew
one full turn. Insert the magnet into the tool and unscrew the locking ring completely (the magnet will
capture the sample cone).

2.	To remove the skimmer cone, loosen each Allen screw only one turn. Carefully insert the magnet
such that it does not touch the tip of the cone, place it on the skimmer and rotate the skimmer until the
notches match the screw positions, and then withdraw the skimmer. The skimmer valve plate will be
visible in the skimmer mounting orifice.

3.	After removing the cones, place them in two separate clean plastic beakers such that the orifices face
upwards. Cover the cones with ultrapure water and sonicate for -10 min. Rinse with ultrapure water.

4.	Mount the cleaned skimmer cone onto the magnet tool, taking care that the magnet does not touch the
tip of the cone.

5.	Insert the skimmer into the mount and turn it until the notches no longer line up with the Allen
screws. Retighten the Allen screws.

6.	Before placing the sample cone, replace the graphite seal (o-ring).

7.	Place the threaded locking ring on the sample cone and insert the magnet. Insert the sample cone into
the front plate. Use the tool to screw the locking ring into the front plate. When tight, remove the
magnet and hand tighten further.

-------
HR-ICPMS Analysis
D-EMMD-PHCB-042-SOP-03

Page 35 of 52

All maintenance activities should be documented on the Yearly Check List.

15.5 Usage Dependent (Refer to the Usage Dependent Log, Appendix 3.6)

Experienced analysts can perform the following usage-dependent maintenance:

•	Entrance slit assembly change

•	Guard electrode change

•	RF coil change

•	Skimmer and sample cone change

•	Torch and sample tube cleanup or maintenance

16.0 Waste Management

16.1	The analyst is responsible for ensuring the safe storage and disposal of all analytical standards and
reagents associated with this method.

16.2	The analyst is responsible for notifying the laboratory manager of disposal needs.

16.3	The analyst is responsible for preserving/storing analyzed samples for future verification.

17.0 Documentation and Document Control

17.1	All information concerning sample preparation, standard preparation, instrument conditions, etc., must be
written in the analyst's notebook. Any unusual problems or conditions must also be noted.

17.2	Record all maintenance performed on the instrument in the maintenance logbook for this particular
instrument.

17.3	Record all analyses including QC samples performed by the instrument in the logbook for this particular
instrument.

17.4	Back up analysis data on a weekly basis. Copy the following folders and files to a CDr: a) Sequence data
folder, b) Sequence file (*.seq), c) Method file (*.mth), and d) Standards files (.std). Place the CD in a
labeled jewel case or paper sleeve, and deliver the data to the laboratory manager. The CD label should
include the date, your name, and a very brief description of the data inside.

18.0 Quality Control

In accordance with EPA Method 6020, the multi-element determination of samples by ICPMS, the following
practices are undertaken to ensure the highest quality analytical data.

18.1	All QC data are stored permanently and are easily available for reference or inspection.

18.2	A standard traceability record book is kept with certificates of analysis of all primary standards in use.


-------
HR-ICPMS Analysis
D-EMMD-PHCB-042-SOP-03

Page 36 of 52

18.3	An Analytical Calibration Traceability Log (see Appendix 3.7) is kept with expiration dates of primary
analytical calibration standards and dates of preparation of stock solutions A, B, and S.

18.4	Instrument detection limits are calculated every three months and kept in the instrument logbook.

18.5	Analytical calibrations are deemed valid only when the regression coefficient (R2) value exceeds 0.999.

18.6	An initial calibration verification standard and a reagent blank sample are run right after a new
calibration.

18.7	Accuracy of analytical calibrations is verified by analyzing Standard Reference Materials such as
SRM1643 and SRM1640. If measurements exceed ±15% of the certified elements, current calibration is
invalidated. New calibration will be established after the cause for QC failure is identified and corrected.

18.8	To obtain data of known quality in all resolution settings, at least one isotope is analyzed in all resolution
settings, where applicable.

18.9	Validity of the existing calibration is verified at a frequency of every 10 analyses. The instrument check
standards must agree within ±15%.

18.11	Duplicate samples are analyzed: One in every 10 samples in an analytical sequence is reanalyzed as a new
sample. A relative percent of difference (RPD) of less than 20% is the tolerance criteria for reanalysis.
RPD is calculated as

IC -C I
( 11 21 )xl00,

(Q +C2)/2

where C\ is the first analysis concentration and C2 is the second analysis (duplicate sample) concentration.

18.12	Intensities of internal standards are monitored in every analysis. When the intensity of an IS in a sample
analysis fails to fall between 80% and 120% of its initial (or reference) value, those samples can either be
re-analyzed, or diluted and reanalyzed.

18.13	Dilution tests are carried out when an analyte lies outside the established calibration region.

The current version of the E2 software does not support all of the QC steps mentioned above on-line. Use the

stand-alone VBA application macro, called "ICPMS Data Flagger," to flag analytical results after a sequence is

completed and the sequence report is generated. Appendix 4 describes how to install and use the ICPMS Data

Flagger application.

Appendix 4: ICPMS Data Flagger

To view the analytical results easily, the data in the sequence summary file created by the current
software version needs major rearrangement. In addition, the sequence output does not have data quality
indicators (flags) for the end user to evaluate an analytical result. Therefore, we developed a VBA
application macro that runs in MS-Excel for post-processing a sequence summary file. This application
does the following:

•	Reads the sequence summary file from a drop-down menu

•	Reads appropriate instrument detection limit (IDL) values file from a drop-down menu

•	Formats species name and rearranges data such that each row contains one sample with all associated
analysis information in columns

•	Evaluates and introduces flags for below instrument detection concentrations, check sample analysis,
SRM sample analysis, and duplicate sample analysis.

•	Outputs analytical concentration data, intensity data, and QC sample data separately.

Installation

This application has already been installed in E2's host computer. To install it in
another computer, copy the "ICPMS Data Flagger.EXE" file from the E2 host
computer (C:\PancrasV.) onto removable media and transfer it to the new computer. icpmsData Fbgger.EXE
Double click the EXE icon to initiate installation, and follow on-screen instructions.

This installation creates folder C:\Flag_Program\ and copies the needed folders and files to run the
application. The following folders are typically installed:

C: \Flag_Program\In\

C :\Flag_Program\Out\

Installation also creates a shortcut icon on the desktop to run the application. It is the user's responsibility
to update IDL information in the lookup file, "LookUp_IDL.xls". in the C:\Flag_Program\Out\ folder.

Application

1.	Find the .CSV sequence report file in the sample sequence folder. The sequence report file is created
and saved by its sequence name (but with a .CSV extension). Copy and move it to folder
C:\Flag_program\In\. {Note: This step may not be required in the future version of ICPMS Data
Flagger.)

2.	Find the ICPMS_VBA application macro on the desktop or in the folder C:\flag_progam\ I
and double click. This action will open the ICPMS Data Flagger application (see
Figure 1). The tab "How to Execute" has step-by-step instructions for first-time users.

3.	Select the sequence report file that you want to process from the "Raw ICPMS" drop-down menu.

4.	Select the "LookUp Data" file the same way. The LookUp file has the IDL and necessary QC
reference data to evaluate and flag analytical results.

5.	Set QC criteria. Default values are entered automatically. Change if needed.

6.	Press "Execute Data Processing," and wait until it is done. Warning messages may pop up if the
flagger does not find duplicate samples. Follow on-screen instructions.

7.	Enter file names in the data export options and press "Click" to export.

8.	Click "Examine Flagged Data" to view the processed data. All data used for processing are present in
the Excel file that opens up. Sheets are named to reflect its contents. Click "Return to ICPMS Data
Flagger" button (top left) to return to the flagger application menu. Do not close the Excel file
directly.

9.	Use "Clear All" to start the next raw data processing. Note: Save reports (from Data Export options)
before clearing all and starting new processing.

10. Use the "Close" button to exit the flagger application.

1. Clinical relevance & summary of test principle

a. Clinical relevance:

Metals ions affect human health in various ways. Some metals (i.e. lead,
cadmium, and mercury) show only deleterious effects on human health. Some
(i.e. selenium and manganese) play an essential role in the human biological
system if within certain concentration ranges, while negative health implications
are observed when concentrations in biological systems are in deficit or excess.
Determination of a person's level of environmental exposure to chemicals
through direct measurement of the substances or their metabolites in human
specimens such as blood is called biomonitoring. Biomonitoring reduces the
uncertainty of determining levels of exposure over making these determinations
through calculations of estimated dose based on analysis of environmental
samples and assumptions about exposure pathways[1], Biomonitoring
measurements are the most health-relevant assessments of exposure because
they indicate the amount of the chemical that actually gets into people from all
environmental sources (e.g., air, soil, water, dust, or food) combined, rather than
the amount that gets into them. The laboratory method described here is a multi-
element technique for monitoring the concentrations of cadmium (Cd), lead (Pb),
manganese (Mn), mercury (Hg), and selenium (Se) in whole human blood for the
purpose of biomonitoring.

There is no known biological role of mercury in the human body. The main
sources of mercury intake in humans are fish, dental amalgams, and
occupational exposures[2]. The main organs affected by mercury are the brain
and the kidneys. Exposure of childbearing-aged women is of particular concern
because of the potential adverse neurologic effects of Hg in fetuses. The health
effects of mercury are diverse and depend on the form of mercury encountered
and the severity and length of exposure. The general population is be exposed
to three forms of mercury: elemental, inorganic, and organic (predominantly
methyl). However, this method tests only for the total amount of mercury in the
blood without regard to chemical form. In the general population, total blood
mercury is due mostly to the dietary intake of organic forms which are formed
through microbial action from inorganic mercury that has deposited in aquatic
environments and bioaccumulated through the food chain (especially into large
predatory fish)[3]. Exposure to inorganic or elemental mercury (e.g. dental
amalgams or occupational exposures) is particularly reflected in urine excretion
rather than blood. Psychic and emotional disturbances are the initial signs of
chronic intoxication by elemental mercury vapors or salts. Those exposed are at
increased risk for parasthesia, neuralgias, renal disease, digestive disturbances,
and ocular lesions [4], Massive exposure over a longer period of time results in
violent muscular spasms, hallucinations, delirium, and death[5]. Except for
methylmercury exposures, blood is considered useful if samples are taken within
a few days of exposure. This is because most forms of mercury in the blood
decrease by one-half every three days if exposure has been stopped. Thus,


-------

mercury levels in the blood provide more useful information after recent
exposures than after long-term exposures. Several months after an exposure,
mercury levels in the blood and urine are much lower. Blood mercury reference
ranges for the U.S. population are listed in Table 10 in Appendix B.

There is no known biological role of lead in the human body. Lead, a naturally
occurring metal, has had many different commercial uses from which a person
can be exposed either in the occupational / manufacturing process or by the
manufactured products such as paint (paint chips, or dust and soil contaminated
from deteriorating paint), solder or pipes (only now in older homes), gasoline
(now outlawed for all but specialized applications), glazes on pottery, hobby uses
(e.g. stained glass), commercial products (e.g. batteries, lead-containing jewelry),
home remedy medicines containing lead compounds and non-Western
cosmetics. Soil contains lead naturally, or from man-made uses of lead such as
paint (near older homes), gasoline (near roadways), mining, manufacturing, and
disposal. The main target for lead toxicity is the nervous system, both in adults
and children. The developing biological systems of children are most sensitive to
the effects of Pb, where effects are being recognized even at blood lead levels
<5 ng/dL [6-10], Acute, elevated lead exposure is associated with anorexia,
dyspepsia, and constipation followed by diffuse paroxysmal abdominal pain.
When lead exposure is high, particularly in children, the person is at increased
risk for encephalopathy [11 ]. The alkyl lead species are highly toxic to the central
nervous system[12], The primary screening method for lead exposure is blood
lead, which primarily reflects recent exposures (excretory half-life in blood is
approximately 30 days)[13]. Lead in blood is primarily (99%) in the red blood
cells. Blood lead reference ranges for the U.S. population are listed in Table 10
in Appendix B. The CDC now uses a reference level of 5 pg/dL to identify
children with blood lead levels that are much higher than most children's levels.
This new level is based on the U.S. population of children ages 1 -5 years who
are in the highest 2.5% of children when tested for lead in their blood. This
reference value is based on the 97.5th percentile of the National Health and
Nutrition Examination Survey (NHANES)'s blood lead distribution in children.
CDC will update the reference value every four years using the two most recent
NHANES surveys [14],

There is no known biological role of cadmium in the human body. The
predominant commercial use of cadmium is in battery manufacturing. Other uses
include pigment production, coatings and plating, plastic stabilizers, and
nonferrous alloys. Since 2001, U.S. cadmium use has declined in response to
environmental concerns. In the United States, for nonsmokers the primary
source of cadmium exposure is from the food supply. People who regularly
consume shellfish and organ meats will have higher exposures. In general, leafy
vegetables such as lettuce and spinach, potatoes and grains, peanuts,
soybeans, and sunflower seeds contain high levels of cadmium due to
bioaccumulation from the soil. Tobacco leaves accumulate high levels of
cadmium from the soil, and smoking is the primary non-occupational source of


-------
blood multi-element analysis by ICP-DRC-MS

IRAT-DLS Method Code: 3016.8-05	Page 8 of 94

cadmium exposure for smokers. Generally, the critical organ for Cd is the
kidney. Kidney dysfunction is one of the most characteristic signs of exposure to
Cd. Workers in an environment with high exposure levels have developed
proteinuria, renal glucosuria, aminoaciduria, hypercalciuria, phosphaturia, and
polyuria. Chronic obstructive lung disease of varying degrees of severities is
frequently seen in Cd workers. Concentration of cadmium in blood of healthy
unexposed adults are in the range 0.1-4 ng/L[15]. Newborn babies are
practically free of Cd[16], Exposure to high concentration of fumes appearing
from heated cadmium metal or compounds has led to acute poisoning and in
some cases to the death of workers[11 ]. Principal symptoms reported were
respiratory distress due to chemical pneumonitis and edema. It has been
estimated that 8 hrs. exposure to 5 g Cd/m3 will be lethal[11], Ingestion of high
amounts of Cd puts a person at increased risk to a rapid onset with severe
nausea, vomiting, and abdominal pain. Cadmium levels in blood, urine, feces,
liver, kidney, hair, and other tissues have been used as biological indicators of
exposure to cadmium. Blood cadmium levels are principally indicative of recent
exposure(s) to cadmium rather than whole-body burdens [17-20], Urine
cadmium levels primarily reflect total body burden of cadmium, although urine
levels do respond somewhat to recent exposure[21]. Blood cadmium reference
ranges for the U.S. population are listed in Table 10 in Appendix B.

Manganese (Mn) is a trace element essential to humans and is associated with
the formation of connective and bony tissue, growth and reproductive functions
and with carbohydrate and lipid metabolism [22], Manganese is also a known
neurotoxin but little information exists about levels of manganese that cause
toxicity. Symptoms of manganese toxicity are similar to Parkinson's Disease and
can also include disorientation, memory impairment, anxiety and compulsive
behavior [23], There is much concern for the levels of manganese in humans
whom are occupationally exposed to it [24-30], Recently, there are growing
concerns over exposure due to contamination of drinking water with manganese
[31-33] and as a result of methylcyclopentadienyl mangangese tricarbonyl (MMT)
used as an anti-knocking additive in gasoline [34-40], Populations suffering from
iron deficiencies are at an increased risk to manganese toxicity because iron
deficiency can result in an accumulation of manganese in the central nervous
system [37], To fully understand the essentiality and toxicity of manganese,
further investigations are needed regarding the levels of manganese in biological
matrices. Group average levels in blood appear to be related to manganese body
burden, while average urinary excretion levels appear to be most indicative of
recent exposures [41], On an individual basis the correlation between the level
of workplace exposure and the levels in blood or urine has always been found to
be a reliable predictor of exposure [25, 41-43], Manganese in blood or urine are
useful in detecting groups with above-average current exposure, but
measurements of manganese in these body fluids in individuals are sometimes
be related to exposure dose after the exposure has ceased. In addition to
individual variability, another factor that limits the usefulness of measuring
manganese in blood, urine, or feces as a measure of excess manganese


-------
blood multi-element analysis by ICP-DRC-MS

IRAT-DLS Method Code: 3016.8-05	Page 9 of 94

exposure is the relatively rapid rate of manganese clearance from the body.
Excess manganese in blood is rapidly removed by the liver and excreted into the
bile, with very little excretion in urine [44, 45], Thus, levels of manganese in blood
or urine are not expected to be the most sensitive indicators of exposure [46],
Typical blood manganese concentrations in humans which have been reported in
the literature are listed in Table 11 of Appendix B.

Selenium is an essential element that is required to maintain good health but
both selenium deficiency and excessive levels of selenium are associated with
several disorders[47, 48], Selenium is a naturally occurring mineral element that
is distributed widely in nature in most rocks and soils. Most processed selenium
is used in the electronics industry, but it is also used: as a nutritional supplement;
in the glass industry; as a component of pigments in plastics, paints, enamels,
inks, and rubber; in the preparation of pharmaceuticals; as a nutritional feed
additive for poultry and livestock; in pesticide formulations; in rubber production;
as an ingredient in antidandruff shampoos; and as a constituent of fungicides.
Radioactive selenium is used in diagnostic medicine. In the body, selenium is
incorporated into proteins to make selenoproteins, which are important
antioxidant enzymes. The antioxidant properties of selenoproteins help prevent
cellular damage from free radicals. Free radicals are natural by-products of
oxygen metabolism that increase risk of chronic diseases such as cancer and
heart disease[48, 49], Other selenoproteins help regulate thyroid function and
play a role in the immune system [50-53], Human selenium deficiency is rare in
the U.S. but is seen in other countries where soil concentration of selenium is
low[54]. There is evidence that selenium deficiency increases the risk of a form of
heart disease, hypothyroidism, and a weakened immune system[55, 56], There is
also evidence that selenium deficiency does not usually cause illness by itself.
Rather, it can make the body more susceptible to illnesses caused by other
nutritional, biochemical or infectious stresses[57]. Symptoms of very high
exposure to selenium, a condition called selenosis, include gastrointestinal
upsets, hair loss, white blotchy nails, garlic breath odor, fatigue, irritability, and
mild nerve damage[47]. Selenium can be detected in the blood, feces, urine,
hair, and nails of exposed individuals, however, field studies have used primarily
blood or urine levels to indicate the degree of selenium exposure[47]. Typical
blood selenium concentrations in humans which have been reported in the
literature are listed in Table 11 of Appendix B.

The laboratory method presented here can be used to achieve rapid and
accurate quantification of five elements of toxicological and nutritional interest
including cadmium (Cd), lead (Pb), mercury (Hg), manganese (Mn) and selenium
(Se) in whole human blood. Use this method to screen blood when people are
suspected to be acutely exposed to these elements or to evaluate chronic
environmental or other non-occupational exposure.

b. Test principle:

This method directly measures the Cd, Mn, Hg, Pb, and Se content of whole
blood specimens using mass spectrometry after a simple dilution sample
preparation step.

During the sample dilution step, a small volume of whole blood is extracted from
a larger whole blood patient specimen after the entire specimen is mixed
(vortexed) to create a uniform distribution of cellular components. This mixing
step is important because some metals (e.g. Pb) are known to be associated
mostly with the red blood cells in the specimen and a uniform distribution of this
cellular material must be produced before a small volume extracted from the
larger specimen will accurately reflect the average metal concentration of all
fractions of the larger specimen. Coagulation is the process in which blood forms
solid clots from its cellular components. If steps are not taken to prevent this
process from occurring, i.e. addition of anti-coagulant reagents such as EDTA in
the blood collection tube prior to blood collection, blood will immediately begin to
form clots once leaving the body and entering the tube. These clots prevent the
uniform distribution of cellular material in the blood specimen even after rigorous
mixing, making a representative sub-sample of the larger specimen unattainable.
It is important that prior to or during sample preparation the analyst identify any
sample having clots or micro-clots (small clots). Clotted samples are not
analyzed by this method due to the inhomogeneity concerns (i.e. all results for
the sample are processed as "not reportable").

Dilution of the blood in the sample preparation step prior to analysis is a simple
dilution of 1 part sample + 1 part water + 48 parts diluent. The effects of the
chemicals in the diluent are to release metals bound to red blood cells making
them available for ionization, reduce ionization suppression by the biological
matrix, prevent clogging of the sample introduction system pathways by
undissolved biological solids, and allow introduction of internal standards to be
utilized in the analysis step. Tetramethylammonium hydroxide (TMAH, 0.4% v/v)
and Triton X-100® (0.05%) in the sample diluent solubilizes blood components.
Triton X-100® also helps prevent biological deposits on internal surfaces of the
instrument's sample introduction system and reduce collection of air bubbles in
sample transport tubing. Ammonium pyrrolidine dithiocarbamate (APDC) in the
sample diluent (0.01%) aids in solubilizing metals released from the biological
matrix. Ethyl alcohol in the sample diluent (1 %) aids solubility of blood
components and aids in aerosol generation by reduction of the surface tension of
the solution. The internal standards, rhodium, iridium, and tellurium, are at a
constant concentration in all blanks, calibrators, QC, and samples. Monitoring
the instrument signal ratio of a metal to its internal standard allows correction for
instrument noise and drift, and sample-to-sample matrix differences.

Liquid samples are introduced into the mass spectrometer through the inductively
coupled plasma (ICP) ionization source. The liquid diluted blood sample is
forced through a nebulizer which converts the bulk liquid into small droplets in an

argon aerosol. The smaller droplets from the aerosol are selectively passed
through the spray chamber by a flowing argon stream into the ICP. By coupling
radio-frequency power into flowing argon, plasma is created in which the
predominant species are positive argon ions and electrons and has a
temperature of 6000-8000 K. The small aerosol droplets pass through a region
of the plasma and the thermal energy vaporizes the liquid droplets, atomizes the
molecules of the sample and then ionizes the atoms. The ions, along with the
argon, enter the mass spectrometer through an interface that separates the ICP
(at atmospheric pressure, ~760 torr) from the mass spectrometer (operating at a
pressure of 10-5 torr). The ions first pass through a focusing region, then the
dynamic reaction cell (DRC), the quadrupole mass filter, and finally are
selectively counted in rapid sequence at the detector allowing individual isotopes
of an element to be determined.

Generally, the DRC operates in one of two modes. In 'vented' (or 'standard')
mode the cell is not pressurized and ions pass through the cell to the quadrupole
mass filter unaffected. In 'DRC' mode, the cell is pressurized with a gas for the
purpose of causing collisions and/or reactions between the fill gas and the
incoming ions. In general, collisions or reactions with the incoming ions
selectively occur to either eliminate an interfering ion, change the ion of interest
to a new mass, which is free from interference, or collisions between ions in the
beam and the DRC gas can focus the ion beam to the middle of the cell and
increase the ion signal. In this method, the instrument is operated in DRC mode
when analyzing for manganese, mercury, and selenium. For selenium, the DRC
is pressurized with methane gas (ChM, 99.999%) which reduces the signal from
40Ar2+ while allowing the 80Se+ ions to pass relatively unaffected through the DRC
on toward the analytical quadrupole and detector. Manganese and mercury are
both measured when the DRC is pressurized with oxygen gas (O2, 99.999%).
They are analyzed at the same flow rate of oxygen to the DRC cell to avoid
lengthening analysis time due to pause delays that would be necessary if
different gas flows were used for the two analytes. The oxygen reduces the ion
signal from several interfering ions (37CI180+, 40Ar15N+, 38Ar1601H+, 54Fe1H+) while
allowing the Mn+ ion stream to pass relatively unaffected through the DRC on
toward the analytical quadrupole and detector. In the case of mercury, collisional
focusing of the mercury ions occurs, increasing the observed mercury signal at
the detector by approximately a factor of two (2x).

Once ions pass through the DRC cell and electrically selected for passage
through the analytical quadrupole, electrical signals resulting from the ions
striking the discrete dynode detector are processed into digital information that is
used to indicate the intensity of the ions. The intensity of ions detected while
aspirating an unknown sample is correlated to an elemental concentration
through comparison of the analyte: internal standard signal ratio with that
obtained when aspirating calibration standards. This method was originally

based on the method by Lutz et al [58], The DRC portions of the method are
based on work published by Tanner et al. [59, 60],

2) Limitations of Method; Interfering Substances and Conditions

a. Interferences addressed by this method

i.	Reduction of argon dimer (40Ar2+) interference on selenium (80Se+) using ICP-
DRC-MS: 40Ar2+ is a polyatomic ion formed in the plasma as a result of a
reaction between the plasma gas (Ar) and itself. The dynamic reaction cell of
the ICP-MS is used to reduce ion signals from polyatomic ions via ion-
molecule reaction chemistry [60, 61], In the reaction cell, methane (ChM)
molecules react with 40Ar2+ ions through a charge transfer reaction. The
products of the reaction are 40Ar+ (ion at a different mass) and 40Ar (neutral).
The background ion signal at m/z 80 is reduced by six orders of magnitude
because of this reaction.

ii.	Reduction of argon nitride (40Ar15N+), argon hydroxide (38Ar16Q1H+)
interference on manganese (55Mn) using ICP-DRC-MS: 40Ar15N+ and
38Ar1601H+ are polyatomic ions formed in the plasma as a result of reactions
between the plasma gas (Ar) and atmospheric gases (N2, O2) or the solvent
(H2O). The dynamic reaction cell of the ICP-MS is used to reduce ion signals
from polyatomic ions via ion-molecule reaction chemistry [60, 61], In the
reaction cell, oxygen molecules react with 40Ar15N+ and 38Ar1601H+ ions
through either charge transfer reactions or oxygen transfer reactions. The
products of the reactions are either neutral molecules and are not detected
(charge transfer), or a new ion with higher mass (oxygen transfer). In either
case, attenuation of the background ion signal at m/z 55 occurs.

iii.	Reduction of37CI18Q+, 39K16Q+, 54Fe1H+ interferences on manganese (55Mn)
using ICP-DRC-MS: 37CI180+, 39K160+, 54Fe1H+ are polyatomic ions created in
the plasma as a result of reactions between elements present in the blood
matrix (CI, K, and Fe) and the solvent (H2O). Due to the high concentrations of
CI, K, and Fe in the blood matrix the resulting ion signals of 37CI180+, 39K160+,
and 54Fe1H+interfere with the measurement of 55Mn+ at m/z 55. The dynamic
reaction cell of the ICP-MS is used to reduce ion signals from polyatomic ions
via ion-molecule reaction chemistry [60, 61], In the reaction cell, oxygen
molecules react with 37CI180+, 39K160+, 54Fe1H+ ions through either charge
transfer reactions or oxygen transfer reactions. The products of the reactions
are either neutral molecules and are not detected (charge transfer), or a new
ions with higher mass (oxygen transfer). In either case, attenuation of the
background ion signal at m/z 55 occurs.

b. Limitations of method (interferences remaining in method)

i. M0O2 interference on 130Te: Molybdenum will combine with oxygen in the DRC
conditions used in this method for Hg analysis to form a polyatomic ion,
98Mo1602+, which interferes with the measurement of the internal standard
i3°Ie+ increased signal at m/z 130 (due to measuring both 130Te+ and
98Mo1602+) results in an erroneously low net intensity for Hg (net intensity =
measured intensity for analyte isotope / measured intensity for internal
standard isotope). If this interference occurs during the measurement of the
calibration standards (i.e. a multi-element calibration stock standard includes
high levels of Mo) it can result in a positive bias for observed mercury
concentrations as a consequence of a nonlinear calibration curve having an
artificially low slope. If this interference occurs during the measurement of an
unknown sample, the reduced net intensity observed can result in reporting an
erroneously low Hg result. This interference has been verified to be of concern
(>5% effect negative bias) at blood molybdenum concentrations greater than
15 ug/L. However, typical levels of molybdenum in whole blood (0.2 - 4.6 ug/L
[62, 63]) are below this. Also, levels of molybdenum in whole blood after acute
exposures have been observed to be <15 ug/L [62], Molybdenum
concentrations below 5 ng/mL in stock calibration standard solutions do not
produce an observable interference.

3) Procedures for collecting, storing, and handling specimens; criteria for
specimen rejection; specimen accountability and tracking

a. Procedures for collecting, storing, and handling specimens: Specimen handling

conditions, special requirements, and procedures for collection and transport are

discussed in the Division of Laboratory Science's (DLS) Policies and Procedures

Manual [64], In general,

i.	No fasting or special diets are required before collection of blood

ii.	Specimen type - whole blood

iii.	Optimal amount of specimen is 1+ mL. Request a minimum volume of 0.25
mL. Volume for one analytical measurement is 0.05 mL.

iv.	Verify sample collection devices and containers are free of significant
contamination ("pre-screened") before use.

v.	Draw the blood through a stainless steel needle into a pre-screened
vacutainer.

vi. Do not freeze blood in blood collection tubes due to risk the tubes cracking.
Transfer to plastic, pre-screened cryovials before freezing.


-------
blood multi-element analysis by ICP-DRC-MS

IRAT-DLS Method Code: 3016.8-05	Page 14 of 94

vii. Once received, store blood collection tubes at refrigerated temperatures (2-8
°C). Transfer to plastic, pre-screened cryovials before freezing. Specimen
stability has been demonstrated for over 1 year at < -20 °C.

b.	Criteria for specimen rejection: The criteria for an unacceptable specimen
include:

i.	Contamination: Improper collection procedures, collection devices, or sample
handling can contaminate the blood through contact with dust, dirt, etc.
Manganese is present in the general environment, found often in combination
with iron, and is present in many alloys (especially stainless steel).

ii.	Low Volume: Request a minimum volume of 0.25 ml_. Volume for one
analytical measurement is 0.05 ml_.

In all cases, request a second blood specimen.

c.	Transfer or referral of specimens: procedures for specimen accountability and
tracking: Location, status, and final disposition of the specimens will be tracked
at least by paper document in the "Study Folder" (created before analysts receive
the samples). Apart from this specimen tracking form, this folder will also contain
the paper print outs of results from analysis of the specimens. Maintain records
for a minimum of 3 years. Use only numerical identifiers for samples within the
laboratory (e.g., case ID numbers) in order to safeguard confidentiality. Access
to personal identifiers for samples will be limited to the medical supervisor or
project coordinator (e.g. non-CDC personnel).

4) Safety precautions

a. General safety

i.	Observe all safety regulations as detailed in the Laboratory Safety Manual and
the Chemical Hygiene Plan. Participate in training regarding blood-borne
pathogens prior to performing this method.

ii.	Observe Universal Precautions when working with blood.

iii.	Wear appropriate gloves, lab coat, and safety glasses while handling all
solutions.

iv.	Take special care when handling and dispensing bases and concentrated
acids. Use additional personal protective equipment which protects face, neck,
and front of body. If TMAH or concentrated hydrochloric acid comes in
contact with any part of the body, quickly wash with copious quantities
of water for at least 15 minutes.


-------
blood multi-element analysis by ICP-DRC-MS

IRAT-DLS Method Code: 3016.8-05	Page 15 of 94

v.	Use secondary containment for containers holding biological or corrosive
liquids.

vi.	The use of the foot pedal on the benchtop automatic pipette is recommended
because it reduces analyst contact with work surfaces that have been in
contact with blood and also keeps the analyst's hands free to hold the
specimen cups and autosampler tubes and to wipe off the tip of benchtop
automatic pipette.

vii.	There are many potential hazards on an operating ICP-MS instrument
including ultraviolet radiation, high voltages, radio-frequency radiation, and
high temperatures. This information is detailed in the ICP-MS System Safety
Manual.

viii.	Transport and store compressed gas cylinders with proper securing
harnesses. For compressed oxygen gas, use regulators which are oil-free and
are equipped with a flash arrestor.

ix. Wipe down all work surfaces at the end of the day with disinfectant.

Disinfectant may be either daily remake of diluted bleach (1 part household
bleach containing 5.25% sodium hypochlorite + 9 parts water) or an equivalent
disinfectant

b. Waste disposal:

i.	Autoclaving: All diluted biological specimens, original biological specimens
being disposed, or consumables which come into contact with biological
specimens (even diluted or aerosolized). Use sharps containers or special
autoclave pans for broken glass / quartz or items which puncture autoclave
bags (e.g. pipette tips).

ii.	Other liquid waste

1. Waste discarded down sink: Only non-corrosive liquid waste (EPA defines
as pH >2 and pH<12.5, 40CFR §261.22) from the ICP-MS instrument can
be discarded at the sink. Flush the sink with copious amounts of water.

2. Waste to be picked up by CDC hazardous waste program: Submit request
for hazardous waste removal of all other liquid waste generated in the CDC
laboratory for this method.

d.	Once mixed, transfer to acid-cleaned, labeled, 50 mL containers (PP,
PMP, or Teflon™) for storage.

e.	Store at room temperature and label appropriately. Expiration is 1 year
from date of preparation.

f.	Pour aliquots of each standard into clean 15mL polypropylene tubes
and label for daily use.

v.	Working calibrators

1.	Purpose: The working calibrators will be analyzed in each run to provide a
signal-to-concentration response curve for each analyte in the method.
The concentration of the analyte of interest in a patient blood sample
dilution is determined by comparing the observed signal ratio
(element/internal standard) from the dilution of the patient blood sample to
the signal ratio response curve from the working calibrators.

2.	Content: Dilutions (1:50) of the corresponding eight intermediate working
calibration standards with base blood and sample diluent.

3.	Preparation: Mix with base blood and diluent (Section 6.c) using a
benchtop automatic pipette to make 1:50 dilutions of the corresponding
eight intermediate working calibration standards immediately prior to
analysis (see Table 8 of Appendix B).

vi.	Base blood

1.	Purpose: This blood pool material will be mixed with the intermediate
working calibrators just prior to analysis to matrix-match the calibration
curve to the blood matrix of the unknown samples.

2.	Preparation: To prepare a mixture of multiple blood sources collected from
anonymous donors to approximate an average blood matrix:

a.	Purchase several bags of whole blood.

b.	Screen each individual bag of blood for concentration of analytes of
interest. See Table 2 in Appendix B for minimum acceptable values

c.	Once screened, mix the acceptable blood together in a larger container
(i.e. acid washed polypropylene (PP), polymethylpentene (PMP), or
Teflon™) and stir for 30+ minutes on a large stir plate (acid wash large
Teflon™ stir bar before use).

d.	Store long-term as smaller portions for daily use (e.g. 2 ml_ cryovials)
according the same storing and handling criteria described in Section
3.

vii.	Internal quality control materials ("bench" QC)

1.	Purpose: Internal (or "bench") quality control (QC) materials are used to
evaluate the accuracy and precision of the analysis process, and to
determine if the analytical system is "in control" (is producing results that
are acceptably accurate and precise). They are included in the beginning
and at the end of each analytical run.

2.	Preparation: To prepare pooled animal or human blood at low-normal and
high-normal concentrations:

Both purchased or in-house prepared quality control materials are suitable
for this purpose if volumes, concentrations meet method requirements and


-------
blood multi-element analysis by ICP-DRC-MS

IRAT-DLS Method Code: 3016.8-05	Page 32 of 94

any spikes of elemental levels are traceable to the National Institute for
Standards and Technology (NIST).

3.	Screening blood: Screen bags of blood for analyte of interest
concentration before mixing together to make 2 separate base blood pools
(for preparing the low and high bench QC materials). Samples can be
screened individually

a.	Keep blood refrigerated whenever possible to minimize microbial
growth.

b.	Because this is only a quick screen of the analyte of interest
concentration, the number of replicates in the blood method can be
reduced to one in order to reduce analysis time.

c.	Select blood for the low bench QC pool which has analyte
concentrations in the low-normal population range. Select blood for
the high and elevated bench QC pools which has analyte
concentrations less than some pre-selected target concentration
values in the high normal population range. See Table 2 in Appendix
B for recommended concentration ranges.

4.	Combining collected blood: The goal is for combining samples is to
approach an 'average' matrix for each pool.

a.	Graduate four acid-washed 10 L carboys (PP or PMP) in 0.5 L
increments (two will be used for decanting into).

b.	Combine collected blood samples into two separate acid-washed 10 L
carboys (PP or PMP), according to their concentrations, for the low
bench and high bench QC pools.

c.	Mix each blood pool using carboy stirrers and large stir plates. Keep
blood refrigerated whenever possible.

5.	Spiking of blood

a.	Analyze three samples of each blood pool. Record these results for
future recovery calculations.

b.	Use these results to determine target analyte concentrations possible
for the pools

c.	Calculate the volume of single element standards needed to spike
each pool to the desired concentrations. See Table 2 in Appendix B
for recommended concentration ranges.

d.	While stirring the pools on large stir plates, spike each pool with
calculated volumes of single element standards (all spiking standards
used must be traceable to NIST).

e.	Continue to stir pools overnight after spiking, then reanalyze.


-------
blood multi-element analysis by ICP-DRC-MS

IRAT-DLS Method Code: 3016.8-05	Page 33 of 94

f. Repeat steps 4 and 5 until all analytes reach target concentrations
keeping track of the total volume of spiking solution added to each
blood pool.

6. Dispensing and storage of blood

a.	Container types: Dispense blood into lot screened containers (i.e. - 2
mL polypropylene tubes). If possible, prepare tubes of QC which have
only enough volume for one typical run + 1 repeat analysis. This
allows for one vial of QC to be used per day of analysis, reducing
chances of contamination of QC materials due to multi-day use.

b.	Labels: Place labels on vials after dispensing and capping if the vials
are originally bagged separately from the caps. This minimizes the
chance for contamination during the process. Include at least the
name of QC pool (text and bar code), date of preparation, and a vial
number on the labels.

c.	Dispensing: Dispensing can be accomplished most easily using a
benchtop automatic pipette in continuous cycling dispense mode.
Dispense the pools in a clean environment (i.e. a class 100 cleanroom
area or hood).

1.	Allow blood to reach room temperature before dispensing (to
prevent temperature gradients possibly causing concentration
gradients across the large number of vials being dispensed
and to prevent condensation problems during labeling of
vials).

2.	Replace the tubing attached to the dispensing syringe (left
when looking at front of the benchtop automatic pipette) with a
length of clean Teflon™ tubing long enough to reach into the
bottom of the 10 L carboy while it is sitting on the stir plate.

3.	Check cleanliness of the benchtop automatic pipette before
use by analyzing 1-2% (v/v) HNO3 which has been flushed
through the benchtop automatic pipette with a portion of the
same solution which has not been through the benchtop
automatic pipette.

4.	Approximately one hour before dispensing begins,

a.	With the large stir plate close to the left side of the
benchtop automatic pipette, begin stirring the blood pool to
be dispensed.

b.	Also during this time, flush the benchtop automatic pipette
with blood from the pool to be dispensed. Place the ends
of the tubing attached to both the sample and dispensing
syringes into the carboy of blood so that blood won't be
used up during this process. Be sure to secure both ends


-------
blood multi-element analysis by ICP-DRC-MS

IRAT-DLS Method Code: 3016.8-05	Page 34 of 94

of tubing in the carboy with Parafilm so they will not come
out during the flushing process.

5. After dispensing the blood into the vials, cap the vials and
label them. Placing labels on vials after capping minimizes the
chance for contamination during the process.

d.	Homogeneity test: Check homogeneity of analyte concentrations in
pool aliquots.

e.	Storage: Store long-term as smaller portions for daily use (e.g. 2 ml_
cryovials) according the same storing and handling criteria described in
Section 3.

f. Optimization solutions
i. PRC optimization:

1.	Purpose: For periodic testing of the DRC cell parameters. Procedure
requires at a minimum a blank (i), an analyte solution (ii), a blank with
interference (iii), and an analyte and interference containing solution (iv).
For Se, only the blank (i), an analyte solution (ii) are needed because the
interference on Se is plasma based.

2.	Content:

Diluent in this section refers to sample diluent (5 ng/L internal standard
mixture (Rh, Ir, Te), 0.4% v/v tetramethyl ammonia hydroxide (TMAH),
1% ethyl alcohol, 0.01% APDC, and 0.05% v/v Triton X-100® as
described in Section 6c.

a.	Solutions for testing elimination of 54Fe1H interference on 55Mn:

i.	Base blood in diluent (1 + 49)

ii.	Base blood in diluent (1 + 49) + 4.5 ng/L Mn

iii.	Base blood in diluent (1 + 49) + 500 ng/L Fe

b.	Solutions for testing elimination of 40Ar2 interference on 80Se:

i.	Base blood in diluent (1 + 49)

ii.	Base blood in diluent (1 + 49) + 90 ng/L Se

3.	Preparation & storage: Prepare different volumes, if needed, by adding
proportionally larger or smaller volumes of solution constituents.
Interference concentrations can be prepared higher as needed by
adjusting the volume of this spike. Keep interference spike volume small
(<0.3 ml_) using a high concentration stock solution (i.e. 1000 mg/mL).
Analyte concentrations can be made higher if needed for sensitivity
reasons by preparing a higher concentration calibrator.

7) Analytical instrumentation setup

(see Section 5 for details on hardware used, including sources)

a. Instrumentation and equipment setup:

i. Configuration for liquid handling

1. FAST valve setup: See Appendix B, Figure 1 for diagram and Section 5.b
"FAST / ESI SC4-DX autosampler accessories" for source information,
sample loop (white nut).

0.5 mm ID probe (red nut) for carrier solution,
nebulizer line (green nut) for transfer of liquid to nebulizer,
sample loop (white nut).

0.8 mm ID probe (blue nut) for diluted samples,
vacuum line (black nut).

a.

Port 1

b.

Port 2

c.

Port 3

d.

Port 4

e.

Port 5

f.

Port 6

2.	Carrier solution uptake: Use peristaltic pump to control uptake flow rate of
carrier solution to the SC-FAST valve. Use of a 'peristaltic to Teflon tubing
adapter' for prevents damage to small i.d. tubing when making connections
(see consumables descriptions in Section 5.b).

3.	Spray chamber waste removal

Use of a 'peristaltic to Teflon tubing adapter' for prevents damage to small
i.d. tubing when making connections (see consumables descriptions in
Section 5.b).

a. Between spray chamber and peristaltic tubing:

i. Spray chambers with threaded connection: Use vendor-supplied
threaded connector on base of chamber, connecting tubing directly
to peristaltic pump tubing through a PEEK adapter or directly.


-------
blood multi-element analysis by ICP-DRC-MS

IRAT-DLS Method Code: 3016.8-05	Page 37 of 94

ii. Spray chambers without threaded connection: Use of specialized
push-on connectors available from various vendors (like UFT-075
from Glass Expansion, Pocasset, MA) are preferred for safety
reasons to direct connection of PVC tubing (e.g. 1/8" i.d. x %" o.d.).
b. Between peristaltic pump tubing and waste container: Connect 1/8"
i.d. x %" o.d. PVC tubing to the white / black peristaltic pump tubing
using a tubing connector (PerkinElmer item # B3140715). Place the
free end of the PVC tubing through the lid of the waste jug (be sure it is
secure). Place waste container in a deep secondary containment tray
in case of overflow.

4. Rinse solution for autosampler:

a.	Rinse solution jug: Leave one of the caps on the top of the rinse jug
loose to allow air venting into the jug as liquid is removed. Otherwise
the jug will collapse on itself as the liquid is removed and a vacuum is
created inside. Use secondary containment tray.

b.	Rinse solution uptake to autosampler rinse station: Use tubing of
different lengths and inner diameters between the rinse solution
container and the autosampler rinse station to control uptake rate of
rinse solution. These can be obtained from the autosampler
manufacturer, their distributors, or custom built in the lab. Optimize
these factors along with fill time in the software so that waste of rinse
solution is minimized and rinse station does not go empty.

c.	Autosampler rinse station waste removal: Gravity drain of waste to the
waste container is sufficient. Use minimum drain tubing to make this
connection. If this tube is too long, the rinse station will not drain
properly.

ii. Gas delivery and regulation

1.	ICP-MS modifications:

a.	Plastic tubing between mass flow controllers and dynamic reaction cell
have been replaced with stainless steel. Stainless steel tubing is
preferred between the reaction gas cylinder / regulator and the back of
the ICP-MS instrument.

b.	A second mass flow controller will be needed (channel B) that does not
send the DRC gas through a 'getter'.

2.	Argon gas: Used for various ICP-MS functions including plasma and
nebulizer.

a. Regulator for argon source (if a dewar): Set delivery pressure of this
regulator at least 10 psi higher than the delivery pressure of the step-


-------
blood multi-element analysis by ICP-DRC-MS

IRAT-DLS Method Code: 3016.8-05	Page 38 of 94

down regulator to allow for pressure drop across tubing that stretches to
the instrument.

b.	Step down regulator (if source of argon is a bulk tank): Place this single
stage regulator in the lab so that incoming argon pressure can be
monitored and adjusted. Set delivery pressure to 10 psig above the
delivery pressure of the filter regulator on the ICP-MS.

c.	Filter regulator at ICP-MS: Single stage "argon regulator filter kit"
supplied with the ICP-DRC-MS. Set the delivery pressure depending
on the instrument setup:

i.	ELAN with a 0-60psi gauge on the filter regulator: 52±1 psi when
plasma is running (need 0-150 psi regulator if using a PolyPro or
PFA nebulizer made by Elemental Scientific Inc).

ii.	ELAN with a 0-150psi gauge on the filter regulator: 90-100 psi
when plasma is running.

3.	Methane (99.99%) gas: Used for dynamic reaction cell interference
removal from selenium isotopes.

a.	Connect to DRC channel A

b.	Set the delivery pressure of regulator to 5-7 psig when gas is flowing.
See section 5.e for part numbers and details.

4.	Oxygen (99.999+%) gas: Used for dynamic reaction cell interference
removal from manganese isotopes.

a.	Connect to DRC channel B.

b.	Set the delivery pressure of regulator to 5-7 psig when gas is flowing.
See Section 5.e for part numbers and details.

c.	Use a brass flash arrestor on outlet side of regulator. See Section 5.e
for part numbers and details.

iii. Chiller / heat exchanger: If using refrigerated chiller, set temperature control to
approximately 18 °C.

b. Instrument and method parameters: See Tables and Figures in Appendix B for a
complete listing of the instrument and method parameters and software screen
shots.

8) The run: quality, execution, evaluation, and reporting

a. Bench QC, reference materials and calibration verification:

i. Bench "QC": Analysis of bench QC permits assessment of methodological
imprecision, determination of whether the analytical system is 'in control' during
the run, and assessment of time-associated trends. Before QC materials can
be used in the QC process, they must be characterized by at least twenty (20)
analytical runs to determine appropriate QC parameters.


-------
blood multi-element analysis by ICP-DRC-MS

IRAT-DLS Method Code: 3016.8-05	Page 39 of 94

Bench QC pool analyte concentrations in this method span the analyte
concentration range of the calibrators including "low-normal" ('Low QC'), "high-
normal" ('High QC'), and "above-normal" ('Elevated QC') concentrations.

In each analytical run the analyst will test each of the three bench QC samples
two times, subjecting them to the complete analytical process. Bench QC pool
samples are analyzed first in the run after the calibration standards but before
any patient samples are analyzed. This permits making judgments on
calibration linearity and blank levels prior to analysis of patient samples. The
second analysis of the bench QC pools is done after analysis of all patient
samples in the run (typically 40-50 patient samples total when analyzing for all
elements in the method) to ensure analytical performance has not degraded
across the time of the run. If more patient samples are analyzed on the same
calibration curve after the second run of the bench QC, all bench QC must be
reanalyzed before and after the additional samples. For example, the schemes
shown in Table 6 in Appendix B are both acceptable ways to analyze multiple
consecutive "runs".

ii.	Reference materials: Use standard reference materials (SRM) from the
National Institute of Standards and Technology (NIST) (i.e. SRM 955c Levels
1 -4) to verify method accuracy. Use previously characterized samples from
proficiency testing program or commercially-produced reference materials
when NIST SRMs are unavailable.

iii.	Calibration verification: The test system is calibrated as part of each analytical
run with NIST-traceable calibration standards. These calibrators, along with
the QCs and blanks, are used to verify that the test system is performing
properly.

b. Perform, evaluate and report a run

/'. Starting the equipment for a run

1.	Power on the computer, printer, and autosampler, and instrument
computer controller.

2.	Peristaltic pump: Set proper tension on peristaltic pump tubing.

3.	Software: Start software for the ICP-MS and autosampler control.

4.	Daily pre-ignition maintenance checks: Perform and document daily
maintenance checks (e.g., Ar supply pressure, interface components
cleanliness and positioning, interface pump oil condition, vacuum pressure,
etc.).

5.	Place probe in adequate volume of carrier or rinse solution: If using an ESI
FAST, manually place carrier probe into carrier solution. If not, send the
autosampler probe to a rinse solution (e.g. autosampler rinse station).

6.	Start the plasma


-------
blood multi-element analysis by ICP-DRC-MS

IRAT-DLS Method Code: 3016.8-05	Page 40 of 94

7.	Start the peristaltic pump: Start the pump running slowly, making sure that
the rotational direction is correct for the way the tubing is set up.

8.	Warm-up time: Allow warm-up time suggested by the manufacturer for the
ICP-MS (e.g. RF generator) after igniting the plasma. There will be
another warm-up time (or "stability time") for the DRC later in this
procedure.

9.	Daily performance check: Perform and document a daily performance
check and any optimizations necessary.

Save new parameters to the "default.tun" and "default.dac" files.

10.	DRC stability time: Best analyte-to-internal standard ratio stability is
typically observed after 1-1.5 hours of analysis of diluted blood samples
using the DRC mode method (~15 measurements of the 5 element panel
can be made in 1 hour). Prepare 50ml_+ of a calibration standard (e.g.
standard 2) to be analyzed repeatedly before the beginning of the run to
achieve a stable analyte-to-internal standard ratio. Time to reach stability
is instrument-specific and learned from performance of runs. See Table 7
in Appendix B for example of setup in the Samples / Batch window and
Table 8 in Appendix B for details of making a working standard.

11.	Readying the instrument for quick-start analysis: Leave the plasma
running to eliminate the need for an initial instrument warm-up period and /
or a DRC stabilization period as long as appropriate planning is made for
sufficient solution supply and waste collection. Analysis of conditioning
samples (diluted blood matrix) can also be scheduled to occur at roughly a
predetermined time. Accomplish this by setting up multiple sample
analyses with extended rinse times (e.g. one 5 element analysis with a
1500s rinse time will take approximately 30 minutes to complete). Initial
samples would be non-matrix, while final samples would be diluted matrix
for conditioning. If running a DRC-only method during these scheduled
analyses, the ICP-MS will remain in DRC-mode for approximately 45
minutes without depressurizing the cell.

12.	Software setup for analysis:

a.	Workspace (files & folders): Verify & set up the correct files and data
directories for your analysis (See Table 1 in Appendix B for defaults).

b.	Samples / batch window: Update the software to reflect the current
sample set. Use a bar code scanner to input data whenever possible.
See Table 1 in Appendix B for times and speeds.

1. Blood vs. aqueous method files:

a. The difference: There are two method files for this one
method (see Table 1 in Appendix B). It is necessary to use
both to accomplish each run because the current
PerkinElmer software will not allow for more than one blank


-------
blood multi-element analysis by ICP-DRC-MS

IRAT-DLS Method Code: 3016.8-05	Page 41 of 94

per method file. The ONLY DIFFERENCE between these
two files is on the Sampling tab where one lists the
autosampler positions of the blood blank and blood-based
calibrators (the "bldblk" method file) and the other lists the
autosampler position of the aqueous blank (the "aqblk"
method file).

b. Use: The ONLY TIME when it matters which of these files
is used is when the measurement action includes "Run
blank" or "Run standards". When the measurement action
is only 'run sample', it does not matter whether the "bldblk"
or "aqblk" method file is used. Analysts typically follow the
pattern below, however, for the sake of consistency and as
a reminder of which blank must be used for which type of
sample. See Table 7 in Appendix B.

i.	The "bldblk" method file: Use to analyze the initial
blood blank (blank for the calibration curve), the blood
calibrators, and the blood blank checks at the very
beginning of the run. The blood blank method defines
the autosampler location of the blood blank and the
blood calibration standards.

ii.	The "aabllc" method file must be used to analyze all QC
materials and patient samples. The aqueous blank
method defines the aqueous blank in autosampler
location.

ii. Preparation of samples for analysis (See Table 6 in Appendix B)

1.	Thaw blood samples; allow them to reach ambient temperature.

2.	Prepare the following solutions into pre-labeled containers using the
benchtop automatic pipette or other volumetric sample transfer device.
See Table 8 in Appendix B for a summary.

a.	Aqueous Blank. Prepare a minimum of two aqueous blanks. One will
be the actual aqueous blank and the other will be a backup ("Aqueous
Blank Check") in case the original aqueous blank is unusable.

b.	Calibrators: Prepare the working calibrators (S0-S8). Prepare SO in
triplicate. One of these SO preparations will be the zero calibrator
(blood blank) for the calibrators; the other two will be analyzed twice
after the last calibrator to collect run blank data that can be used in
calculating method limit of detection (LOD).

c.	Patient & QC Samples: Before taking an aliquot for analysis,
homogenize the sample thoroughly.

After preparation, mix and cover. Place prepared dilutions on the
autosampler of the ICP-MS in the order corresponding to the sequence
setup in the ICP-MS software.


-------
blood multi-element analysis by ICP-DRC-MS

IRAT-DLS Method Code: 3016.8-05	Page 42 of 94

Room temperature is acceptable for the original samples for the work
day.

NOTE: Samples must be analyzed within 24 hours of preparation to
obtain valid results for selenium. The method has been validated to
produce valid results for other Pb, Cd, Hg, and Mn even 48 hrs after
sample preparation. See critical parameter test results in Appendix A for
details.

iii.	Start the analysis using the ICP-MS software.

iv.	Monitor the analysis in real-time as much as possible. If necessary, leave the
run to complete itself unattended as long as appropriate planning is made for
either overnight operation or Auto Stop (see below).

Monitor the analysis for the following:

1.	Verify proper operation of the instrument (proper loop filling, sample
reaching nebulizer in correct timing, autosampler arm moving properly, etc
...).

2.	Verify that background signal from instrument and reagents are low.

Helpful checks when diagnosing high background problems include:

a.	Water to be used in Aq Blank Checks and dilutions.

b.	Diluent before and after being flushed through the benchtop automatic
pipette.

If contamination is observed from the pipette, flush the pipette with
>500 ml_ of nitric acid solution (< 5% v/v HNO3) and retest.

c.	Comparison with other instruments.

3.	Verify analyte / internal standard ratio stability

The net intensity (analyte / internal standard ratio) of the measurements
made while stabilizing the DRC can be evaluated to determine the
readiness of the system to begin analysis. Continual trending in this ratio
indicates that unwanted instrument drift will occur within the run.

4.	Verify calibration curves meet R2 requirements (minimum of 0.98, typically
0.99 to 1.000).

5.	Verify bench QC results are within the acceptable limits.

If an analyte result for the beginning QC material(s) falls outside of the ±
3SD limits, then the following steps are recommended:

a.	Evaluate the blank results.

b.	Evaluate the reproducibility of the 3 replicates within the
measurements.

c.	Evaluate the consistency of the internal standard across the
measurements (esp. the calibrators).


-------
blood multi-element analysis by ICP-DRC-MS

IRAT-DLS Method Code: 3016.8-05	Page 43 of 94

d.	Evaluate calibration curves. If a particular calibration standard is
obviously in error, it can be re-analyzed as a sample (old or new
dilution) and incorporated into the curve through data reprocessing as
a calibrator. As a last resort, a single calibration point per analyte
between or including S2 and S7 can be removed from the curve (Do
not drop SO, S1 or S8). Follow up problems with calibration standards
with appropriate corrective actions (e.g. re-preparation of intermediate
working standards or troubleshooting instrument parameters).

e.	Prepare a fresh dilution of the failing QC material (same vial) and
reanalyze it to see if the QC dilution was not properly made.

f.	Prepare a fresh dilution of the failing QC material (unused vial) and
analyze it to see if the QC vial had become compromised.

g.	Prepare and analyze new working calibrators.

h.	Test a different preparation of intermediate working calibration
standards.

If these steps do not result in correction of the out-of-control values for QC

materials, consult the supervisor for other appropriate corrective actions.

6.	Verify good precision among replicates of each measurement.

7.	Verify consistent measured intensities of the internal standards.

Some sample-to-sample variations are to be expected, however,
intensities drifting continuously in one direction resulting in failing results
for ending QC indicate the instrument needs additional pre-conditioning
before the run or environmental conditions are changing too much
around the instrument.

8.	Verify elevated patient results.

Refer to Figure 4 in Appendix B for flowchart.

a.	Confirming an elevated concentration: Repeat for confirmation any
sample having a concentration greater than the 1UB threshold. See
Table 9 in Appendix B.

b.	Dilution of a sample to within the calibration range: Repeat in duplicate
with extra dilution any sample having a concentration greater than the
highest calibration standard to bring the observed result within the
concentration range of the calibrators. See Table 7 in Appendix B for
validated extra dilutions.

c.	Confirming proper washout after an elevated sample: When monitoring
the analysis in real-time, if a sample concentration is greater than the
highest concentration validated for washout (see Table 9 of Appendix
B), do the following to verify that the run is still in control for low
concentration samples before proceeding with analysis.

i. Stop run following elevated sample


-------

IRAT-DLS Method Code: 3016.8-05	Page 44 of 94

ii. Verify that the run is still in control for lower concentration samples
before proceeding with analysis. Analyze 2 blood blank checks
followed by a low bench QC washout check. If the low bench QC
wash check is not in control (within ± 3SD limits), repeat these 3
check samples until washout is verified before proceeding with
analysis.

Example:

3016 BldBlkChk Washl
3016 BldBlkChk Wash2
LBXXXXX Wash

/'//. If the run is not verified in-control for low concentration samples
before the next samples are analyzed, see Section 8.b.vii.2. for
directions.

v.	Overnight operation or using auto stop: The run may be left to complete itself
unattended as long as appropriate planning is made (e.g. sufficient solution
supply and waste collection). Turn on the AutoStop feature of the ICP-MS
software. Delay the shutdown at least 10 minutes (use peristaltic pump speed
approximately that of the method wash) to rinse the sample introduction
system of blood matrix before turning off the plasma. It will be necessary to
replace the sample peristaltic pump tubing the next day since it will have been
clamped shut overnight. Enable "Auto Start / Stop" is on the "AutoStop" tab of
the Instrument window.

vi.	Records of results: Run results will be documented after each run in both
electronic and paper form.

1.	Electronic records: Transfer data electronically to the laboratory
information system. When keyboard entry must be used, proofread
transcribed data after entry.

a.	Export data from the ICP-MS software using "original conditions" or
files and folders used during the analysis. Use descriptive report
filenames (e.g. 2005-0714a_group55.txt). In the ICP-MS software
under "Report Format" (METHOD window, REPORT tab) choose the
"Use Separator" option, and under the "File Write" Section choose
"Append."

b.	Move the generated .TXT data file to the appropriate subdirectory on
the network drive where exported data are stored prior to import to the
laboratory information management system.

c.	Import the instrument file into the laboratory information system with
appropriate documentation (e.g. instrument ID, analyst, calibration
standards lot number, and run or sample specific comments).

2.	Paper records: Printed run sheets must be documented with

i. Analyst initials


-------
blood multi-element analysis by ICP-DRC-MS

IRAT-DLS Method Code: 3016.8-05	Page 45 of 94

ii.	Instrument ID

iii.	Date of analysis and run # for the day

vii. Analyst evaluation of run results:

1. Bench quality control: After completing a run, and importing the results into
the laboratory information system, evaluate the run bench QC according to
laboratory QC rules. The QC limits are based on the average and standard
deviation of the beginning and ending analyses of each of the bench QC
pools, so it will not be possible to know if the run is in control until
statistically reviewed.

a.	Rules for bench quality control evaluation: The following are the CDC
DLS QC rules for three QC pools per run with two or more QC results
per pool.

i.	If all three QC run means are within 2Sm limits and individual
results are within 2Si limits, then accept the run.

ii.	If one of the three QC run means is outside a 2Sm limit - reject run
if:

1.	Extreme Outlier - Run mean is beyond the characterization
mean ± 4Sm

2.	3S Rule - Run mean is outside a 3Sm limit

3.	2S Rule - Two or more of the run means are outside the same
2Sm limit

4.	10 X-bar Rule - Current and previous 9 run means are on
same side of the characterization mean

iii.	If one of the QC individual results is outside a 2Si limit - reject run
if:

1.	Extreme Outlier - One individual result is beyond the
characterization mean ± 4Sm

2.	R 4S Rule - 2 or more of the within-run ranges in the same run
exceed 4Sw (i.e., 95% range limit)

Note: Since runs have multiple results per pool for 3 pools, the
R 4S rule is applied within runs only.

Abbreviations:

Si = Standard deviation of individual results.

Sm = Standard deviation of the run means.

Sw = Within-run standard deviation.

b.	Implications of QC failures: If the DLS SAS program declares the run
"out of control" for any analyte, use the following to determine the
implications on usability of the data from the run.


-------
blood multi-element analysis by ICP-DRC-MS

IRAT-DLS Method Code: 3016.8-05	Page 46 of 94

i.	For 1 or 2 analvtes: ONLY the analytes which were "out of control"
are invalid for reporting from the run.

ii.	For 3 or more analvtes: All results, regardless of analyte, are
invalid for reporting from the run.

2. Patient results:

a. Elevated concentrations: Refer to Figure 5 in Appendix B for flowchart.

i.	Boundaries requiring confirmatory measurement:

1.	Results greater than the first (1 UB) or second (2UB) upper
boundaries.

The concentrations assigned to 1 UB and 2UB for an element
is determined by study protocol but default concentrations are
in Table 9 in Appendix B.

a.	Results greater than the first upper boundary (1 UB):

Confirm by repeat analysis of a new sample preparation
concentrations observed greater than the "first upper
boundary" (defined in the laboratory database as the

"1 UB"). Report the first analytically valid result, as long as
the confirmation is within 10%. Continue repeat analysis
until a concentration can be confirmed.

b.	Analyst reporting of elevated results: Report any patient
results confirmed to be greater than the second upper
boundary (2UB) as an "elevated result".

2.	Results greater than highest calibrator: Samples that exceed
the high calibrator must be prepared with minimum extra
dilution in duplicate to bring the observed result within the
calibration range (< S8). Report the first analytically valid
result (i.e. the first one within the calibration range), as long as
the confirmation is within 10%. Continue repeat analysis until
a concentration can be confirmed.

ii.	Concentrations reguiring verification of washout: Following a result
greater than the highest concentrations validated for washout (see
Table 9 of Appendix B) do the following:

1.	If the run was determined to be in-control for low concentration
samples before the next samples were analyzed, no further
action is required.

2.	If the run was not determined to be in-control for low
concentration samples before the next samples were analyzed
confirm by re-analysis the results for the 2 samples
immediately following the elevated sample. Report the results
if they confirm the initial results within ±10% or ±3SD of the low
bench QC, whichever is greater.


-------
blood multi-element analysis by ICP-DRC-MS

IRAT-DLS Method Code: 3016.8-05	Page 47 of 94

b. Unacceptable reproducibility: If the range of the three replicate
readings (maximum replicate concentration value - minimum replicate
concentration value) for a single sample analysis is greater than the
range maximum criteria listed in Table 9 in Appendix B and the range
of the three replicate readings is greater than 10% of the observed
concentration, do not use the measurement for reporting. Repeat the
analysis of the sample.

viii. Submitting final work for review: All analyses must undergo quality control and
quality assurance review. After appropriately documenting the run in the
laboratory information system (e.g. sample and run QC, and run and sample
comments), inform the first level reviewer of the completed work and submit
any printed documentation.

9) Routine equipment maintenance and data backups

Maintenance activities will be documented in the instrument logbook.

a.	Equipment maintenance: Analysts are expected to regularly evaluate the need
for, and when necessary perform, cleaning, replacement, or re-positioning of
components in ICP-MS the sample introduction system, interface, ion optics
region, and equipment required resources (e.g. autosampler, exhaust,
compressed gases, and coolant). Frequency of equipment maintenance will be
dependent on instrument throughput.

b.	Parameter optimizations: Analysts are expected to optimize instrument
parameters.

i.	Dual detector calibration: Perform dual detector calibration regularly for any
element exceeding 1,000,000 cps for calibration standard 8. This is typically
only Pb. Dual detector calibration solution is described in Section 6.f.ii.
Frequency of dual detector calibration is typically monthly when throughput
requires multiple analytical runs per week, or as needed for optimized linearity.

ii.	PRC optimizations: DRC conditions (cell gas flow rate and RPq value) can be
verified by analyzing the DRC optimization solutions (see Section 6.f.i) as
needed to ensure proper reduction of potential ICP-MS interferences.

c.	Data backup: Data on the instrument computer will be backed up via two backup
routines. Files used and produced by the ICP-MS in analyzing samples will be
backed up and kept a minimum of two years after analysis.

i.	Daily backups to secondary hard drive: Program automatic backups of the
relevant computer files to occur each night onto a secondary hard drive to
prevent loss of data from failure of primary hard drive.

ii.	Weekly backup: Backup relevant computer files weekly either to secondary
hard drive which is remote to the laboratory or to removable media which will
be placed remote to the laboratory for retrieval in the case of catastrophic data
loss elsewhere.

10)Reporting	thresholds

a.	Reportable range: Blood elemental concentrations are reportable in the range
between the method LOD and the highest calibrator (see 'calibrator
concentrations' in Table 1) times the maximum validated extra dilution (see Table
8). Above the highest concentration verified, extra dilutions are made of the
blood sample to bring it within the reportable range.

b.	Reference ranges (normal values): In this method the 95% reference ranges
(see Appendix B, Table 10) for these elements in blood fall within the range of
the calibrators.

c.	Action levels: Report concentrations observed greater than the "second upper
boundary" (defined in the laboratory database as the "2UB") to the QC reviewer
as an "elevated result". The concentration assigned to the 2UB for an element is
determined by study protocol but default concentrations are listed in Table 9 in
Appendix B. The protocol for supervisors reporting elevated results to medical
personnel is defined according to the study protocol. But typically,

i.	Lead: Levels of lead in blood of children ages 1 -5 are considered elevated
above 5 ng/dL and chelation treatment is recommended at blood lead levels
>45 ng/dL[65]. The Occupational Safety and Health Administration regulations
use a blood lead level of 40 ng/dL as cause for written notification and a
medical exam, and a blood lead level of 60 ng/dL as cause for medical
removal from exposure[66],

ii.	Cadmium: Levels of concern for cadmium in blood is >5 ng/L[67, 68],

iii.	Mercury: The American Conference of Governmental Industrial Hygienists has
a biological exposure index (BEI) of 15 ng/L for inorganic mercury in blood
(end of shift at end of work week)[68],

iv.	Manganese: Insufficient data to establish an action level.

v.	Selenium: >500 ng/L [69, 70]

11)	Method Calculations

a.	Method limit of detection (LODs): The method detection limits for elements in
blood specimens are defined as 3 times so, where so is the estimate of the
standard deviation at zero analyte concentration. So is taken as the y-intercept of
a linear or 2nd order polynomial regression of standard deviation versus
concentration (4 concentration levels of the analytes in blood each measured 60
times across at least a 2-month timeframe). Method LODs are re-evaluated
periodically.

b.	Method limit of Quantitation (LOQ): The Division of Laboratory Sciences does not
currently utilize limits of quantitation in regards to reporting limits [71],

c.	QC Limits: Quality control limits are calculated based on concentration results
obtained in at least 20 separate runs. It is preferable to perform separate
analyses on separate days and using multiple calibrator lot numbers,


-------
blood multi-element analysis by ICP-DRC-MS

IRAT-DLS Method Code: 3016.8-05	Page 49 of 94

instruments, and analysts to best mimic real-life variability. The statistical
calculations are performed using the SAS program developed for the Division of
Laboratory Sciences (DLS_QC_compute_char_stats.sas).

12) Alternate methods for performing test and storing specimens if test system
fails:

If the analytical system fails, the analysis may be setup on other ICP-MS instruments
in the laboratory. If no other instrument is available, store the specimens at ~4 °C
until the analytical system can be restored to functionality. If interruption longer than
4 weeks in anticipated, then store blood specimens at < -20 °C.

Appendix A: Critical parameter test results (continued)

Critical parameter test #3: This test evaluated the significance of the dynamic reaction
cell gas flow rate of the reaction gas (oxygen and methane) while analyzing blood
samples for elements analyzed in DRC mode (Hg, Mn, and Se). The cell gas flow rate
for Mn and Hg is oxygen (62) and the per method setting is 1.2 mL/min. The cell gas
flow rate for Se is methane (ChM) and the per method setting is 0.84 mL/min.

Test details:

1.	Prepare a set of dilutions (calibrators, blanks, reference material, dummy samples)
for analysis in triplicate (three separate sets of tubes).

2.	Analyze them in three separate runs on the same day using the same instrument.

3.	Change the cell gas flow rate.

Appendix A: Critical parameter test results (continued)

Critical parameter test #5: This test evaluated the significance of the Axial Field Voltage
(AFT) while analyzing blood samples for whole blood metals. The Axial Field Voltage
may vary on each instrument. The Axial Field Voltage was increased and decreased by
20%. The results are presented in Table 7.

Test details:

1.	Prepare a set of dilutions (calibrators, blanks, reference materials, fake samples) for
analysis in triplicate (three separate sets of tubes).

2.	Analyze them in three separate runs on the same day, same instrument.

3.	Change the AFV value +/-100 V.

Table 7. Ruggedness testing results: Evaluating the significance of Axial Field Voltage on sample
stability. Test performed on December 20, 2010 by Deanna Jones. Results below are the average of
the beginning and ending QC results for each analytical run.

sample flush

default is 4s at 1.5 rpm (-160 uL/min, ESI DXi peristaltic pump,

Time can be optimized as needed to adequately fill the FAST
loop. Time and rpm can be optimized as needed to using a
different style peristaltic pump (maintaining approximate liquid
flow rate). As a matter of lab practice, set this time to equal the
loop fill time in the ESI FAST program. As long as the combined
time of sample flush + read delay is equal to the time required for
signal to reach stability, analytical measurement will be good.

read delay

60s at 1.5 rpm (-160 uL/min, ESI DXi peristaltic pump, FAST
sample introduction system)

Time can be optimized as needed to reach signal stability before
beginning analysis. Time and rpm can be optimized as needed to
using a different style peristaltic pump (maintaining approximate
liquid flow rate). As a matter of lab practice, set this time equal to
the total time required for the signal to reach stability minus the
loop fill time. As long as the combined time of sample flush +
read delay is equal to the time required for signal to reach
stability, analytical measurement will be good.

wash

30s at 1.5 rpm (-160 uL/min, ESI DXi peristaltic pump, FAST

Time can be optimized to allow for changes in FAST loop rinsing
(must be greater than total time of steps in FAST program after
the initial "on rinse" command). Time and rpm can be optimized
as needed to using a different style peristaltic pump (maintaining
approximate liquid flow rate).

introduction system:

If the FAST sample introduction system is not available on any
instruments, the method can still be implemented, but these
changes will need to be made in the ELAN (and ESI software if
present). Peristaltic pump speeds are for DXi pump; adjust
accordingly if another pump is installed.

•	sample flush: Default is ~30s at-16 rpm. Set so that solution
reaches nebulizer.

•	read delay: Default is 45s at -5 rpm. Set for best
reproducibility of replicate measured intensities.

•	wash: Default is 60s at -11rpm. Set to prevent significant
carry-over from one sample to the next.

•	If using ESI autosampler without FAST, disable FAST in the
ESI software before running analysis.

** By splitting the dispense step of diluent into two or more portions, liquids pulled up into the right
pipette tip are flushed out more completely. For example, when preparing a working calibrator, do
the preparation in two steps: in step 1, dispense 2400 jj.L diluent + 50 jj.L; in step 2, dispense 2400
M.L diluent + 50 m.L base blood to prepare a 2.5 mL total volume dilution.

H Extra dilution is performed on urine samples whose concentration is greater than the highest
calibrator listed in the 'calibrator concentrations' section of Table 1 in the Appendix B.

Maximum extra dilution (see Appendix A, ruggedness test #6 for details)
20xforCd, Hg, Mn, Pb, and Se





Any extra level of dilution up to 20x (see Appendix A, Experiment 6) can be prepared as long as the
4.8:5 ratio of diluent to total dilution volume is maintained. Use of the lowest possible dilution level
is preferred to minimize differences between the calibrators and the samples (i.e. 2x dilution is
preferred over 10x if 2x is sufficient to dilute analyte into the documented linearity range).

Figure 1. Configuration of tubing and devices for liquid handling using FAST
sample introduction.

Below shows the correct connections to the 6-port FAST valve. The two diagrams show
the differences in liquid flow directions when the valve changes from "Load" to "Inject"
This change is internal to the valve. The shift of the valve cannot be seen, but it can be
heard, and felt (with hand on the valve). The light indicators on the actuator body also
indicate the valve position.

Figure 3a. ESI SC4 autosampler screen shots (main page). Additional flush times
and "Max Rinse Time" are approximate. Optimize these for best reduction of elemental
carry-over between samples. Tray types can be changed to allow for different volumes
of diluted sample digests. 'FAST control' must be enabled before start of method, but
does not need to be used in instrument optimization (pre-analysis) steps. Rinse and
additional flush times for eliminating carry-over from one sample to the next while using
the minimum amount of rinse solution.

A rinse time of -1 causes the rinse station to be skipped.

A rinse time of 0 causes the probe to only dip into the station, but spends no time there.

Additional flush times can be optimized to keep the rinse station full while not using too
much rinse solution. The inner diameter size of the tubing providing the rinse solution to
the rinse station determines how quickly the station will fill. Various sizes are available
for purchase or can be made in the laboratory.

Figure 3g. ESI SC4 autosampler screen shots ("FAST" page). Timer A can be
optimized to achieve proper filling of loop with diluted sample digestate. Timers B, C, D.
E, and F control rinsing the loop after analysis and can be optimized for eliminating
carry-over from one sample to the next while using the minimum amount of rinse
solution. Save the file with the name "DLS 3016.8 FAST parameters.txt". It can be
found in the directory C:\Program Files\ESI\ESI-SC\.

Manually clicking the "Load" button prior to starting analysis will ensure the position of
the actuator is always the same at the beginning of the analysis.

Manually clicking the "Vacuum On" button prior to starting the analysis will help initial
sample uptake to be consistent (the vacuum pump may be slow to start for the first
sample if this is not done, possibly resulting in loop filling inconsistencies)

1) Clinical relevance and summary of test principle

a.	Clinical Relevance:

This method is used to achieve rapid and accurate quantification of three
elements of toxicological and nutritional interest including Zinc (Zn), Copper (Cu)
and Selenium (Se). The method is useful to screen serum when people are
suspected to be acutely exposed to these elements or to evaluate chronic
environmental or other non-occupational exposure.

b.	Test Principle:

Inductively coupled plasma dynamic reaction cell mass spectrometry (ICP-DRC-
MS) is a multi-element analytical technique capable of trace level elemental
analysis [1-4], This ICP-DRC-MS method is used to measure the entire panel of
3 elements, or any subgroup. Liquid samples are introduced into the ICP through
a nebulizer and spray chamber carried by a flowing argon stream. By coupling
radio-frequency power into flowing argon, a plasma is created in which the
predominant species are positive argon ions and electrons and has a
temperature of 6,000-8,000 K. The sample passes through a region of the
plasma and the thermal energy atomizes the sample and then ionizes the atoms.
The ions, along with the argon, enter the mass spectrometer through an interface
that separates the ICP (at atmospheric pressure, ~760 torr) from the mass
spectrometer (operating at a pressure of 10"5 torr). The ions pass through a
focusing region, the dynamic reaction cell (DRC), the quadrupole mass filter, and
finally are counted in rapid sequence at the detector allowing individual isotopes
of an element to be determined.

Generally, the DRC operates in one of two modes. In 'vented' (or 'standard')
mode the cell is not pressurized and ions pass through the cell to the quadrupole
mass filter unaffected. In 'DRC' mode, the cell is pressurized with a molecular
gas for the purpose of causing collisions and/or reactions between the molecular
gas and the incoming ions. In general, collisions or reactions with the incoming
ions selectively occur to eliminate an interfering ion by changing the ion of
interest to a new mass which is free from interference, or causing collisions
between ions in the beam and the DRC gas which can focus the ion beam to the
middle of the cell thus increasing the ion signal. In this method, the instrument is
operated in 'DRC' mode when measuring Zn, Cu and Se, and the cell is
pressurized with 99.99+% ammonia gas which collides or reacts with the
incoming ions to eliminate interfering ions and leave the ion of interest to be
detected.

After leaving the DRC cell, the ions are focused with ion optics into a quadrupole
mass analyzer with a nominal mass resolution of 0.7 amu. The quadrupole is
sequentially scanned to specific mass to charge ratio of each analyte and
intensity is detected with a pulse detector. Electrical signals resulting from the
detection of ions are processed into digital information that is used to indicate
first the intensity of the ions and then the concentration of the element. This
method was originally based on the methods by Piraner and Walters [5-8] and


-------
Serum Multi-Element ICP-DRC-MS
DLS Method Code: DLS: 3006.8-03	Page 8 of 86

the DRC portions of the method are based on work published by Tanner et al. [2,
3], The isotopes measured by this method are zinc (m/z 64), copper (m/z 65) and
selenium (m/z 78) and the internal standard, gallium (m/z 71). Serum samples
are diluted 1:1:28 with >18 MQ-cm water and diluent containing gallium (Ga) for
multi-internal standardization.

2) Limitations of method; interfering substances and conditions

a.	Interferences addressed by this method

i.	Correction and elimination of interferences (64Ni, 36Ar14N2) on zinc (64Zn).

1.	Mathematical correction for nickel (64Ni) interference:

The correction equation (-0.035297* 60Ni) is used in the "Equations" tab of
the method to correct the counts observed as m/z 64 to exclude counts
due to 64Ni.

2.	Elimination of 36Ar14N2interference using DRC: The dynamic reaction cell
of the ELAN ICP-DRC-MS is used in this method to eliminate interference
from 36Ar14N2 onto zinc at m/z 64. See Section 1 .b for an explanation of
this process.

ii.	Elimination of interferences (40Ar25Mg, 36Ar14N21H) on copper (65Cu) using DRC.
The dynamic reaction cell of the ELAN ICP-DRC-MS is used in this method to
eliminate the interference 40Ar25Mg, 36Ar14N21H on copper at m/z 65. See Section
1 .b for an explanation of this process.

iii.	Correction and elimination of interferences (78Kr, 38Ar40Ar, ^Ar^Ca) on selenium
(78Se).

1.	Mathematical correction for krypton (78Kr) interference:

The correction equation (-0.030461 *83Kr) is used in the "Equations" tab of
the method to correct the counts observed as m/z 78 to exclude counts
due to 78Kr.

2.	Elimination of 38Ar40Ar, 38Ar40Ca interference using DRC: The dynamic
reaction cell of the ELAN ICP-DRC-MS is used in this method to eliminate
interference from ^Ar^Ar, 38Ar40Ca onto selenium at m/z 78. See Section
1 .b for an explanation of this process.

b.	Limitations of method

i.	48Ca16Q1H interference on copper (65Cu):

It has been determined that a small interference remains at m/z 65 when the
serum matrix contains very high calcium levels. Even at extreme calcium
levels, this interference has not been found to be significant (< 1%).

ii.	Time between dilution of serum materials and analysis:

Selenium is not stable in the diluted sample for more than 7 hours. Diluted
serum must be analyzed within 7 hours of preparation (see Appendix B, test 5
for details).

3) Procedures for collecting, storing, and handling specimens; criteria for
specimen rejection; specimen accountability and tracking

a.	Procedures for collecting, storing, and handling specimens:

Specimen handling conditions, special requirements, and procedures for
collection and transport are discussed in the Division of Laboratory Science's
(DLS) Policies and Procedures Manual [5], In general, if more than one
vacutainer of blood is to be drawn from an individual, collect the trace metals
tube second or later. Draw the blood through a stainless steel needle into a pre-
screened 7-mL vacutainer. Allow the blood in the stoppered vacutainer clot for
30-40 minutes, but not longer than 60 minutes. Without opening the vacutainer,
centrifuge it for 10 minutes at 2400 rpm. Use a pre-screened serum separator to
remove the serum from the clot. Under a laminar flow hood, pour the serum in
the serum separator into pre-screened polyethylene vials.

i.	No fasting or special diets are required.

ii.	Use sterile, lot screened collectors for specimen acquisition.

iii.	Transport serum specimens at < 4°C.

iv.	Once received, store at < -20°C until time for analysis. Re-freeze remaining
portions < -20°C after analytical aliquots are withdrawn. Thawing and refreezing
samples has not been found to compromise sample results.

v.	Specimen stability for at 3 years has been demonstrated at < -70°C storage
conditions.

vi.	Acceptable containers for analytical aliquots include vials (like polyethylene and
polypropylene) and 7-mL vacutainers determined by pre-screening to be free of
significant contamination of the metals tested in this method. A 3-mL vacutainer
size will not produce the optimal volume of serum for this test. Externally
threaded containers are preferred because they are less prone to contamination
of the specimen and to leaks (internally threaded containers can develop leaks
when biological material dries within the threads, compromising resealing).

b.	Criteria for specimen rejection:

Specimen characteristics that compromise test results are indicated above.
Reasons for rejection of a sample for analysis include

i.	Low volume: Optimal amount of serum is 1 mL, minimum is 0.8 mL. The volume
of serum used for one analysis is 0.15 mL.

ii.	Contamination: Improper collection procedures or collection devices can
contaminate the serum by contact with dust, dirt, etc.

In all cases, request a second serum specimen.


-------
Serum Multi-Element ICP-DRC-MS
DLS Method Code: DLS: 3006.8-03	Page 10 of 86

c. Transfer or referral of specimens; procedures for specimen accountability and
tracking:

Location, status, and final disposition of the specimens will be tracked and
records are maintained according to the DLS Policies and Procedures Manual
[5], Use only numerical identifiers for samples within the laboratory (e.g., case ID
numbers) in order to safeguard confidentiality. Only the medical supervisor (MS)
or project coordinator (PC) (i.e. non CDC personnel) will have access to the
personal identifiers.

4) Safety precautions

a.	General safety

i.	Observe all safety regulations as detailed in the Division (DLS) Safety Manual.
Additional information can be found in your lab's chemical hygiene plan.

ii.	Observe Universal Precautions when working with serum.

iii.	Wear appropriate gloves, lab coat, and safety glasses while handling all
solutions.

iv.	Exercise special care when handling and dispensing concentrated nitric acid.
Add acid to water. Nitric acid is a caustic chemical that is capable of causing
severe eye and skin damage. If nitric acid comes in contact with any part of
the body, quickly wash the affected area with copious quantities of water
for at least 15 minutes.

v.	Use secondary containment for containers holding biological or corrosive liquids.

vi.	The use of the foot pedal on the benchtop automatic pipette is recommended
because it reduces analyst contact with work surfaces that have been in contact
with serum and also keeps the analyst's hands free to hold the specimen cups
and autosampler tubes and to wipe off the dispensing tip.

vii.	Training will be given before operating the ICP-DRC-MS, as there are many
possible hazards including ultraviolet radiation, high voltages, radio-frequency
radiation, and high temperatures. This information is also detailed in the
PerkinElmer ELAN® ICP-DRC-MS System Safety Manual.

viii.	Place ammonia gas cylinders (either in use or in storage) in a cabinet which is
well ventilated to the house exhaust. Do not place ammonia cylinders on their
side while in use as the cylinder valve can become "frozen" in place as a result
of the cooling capacity of expanding ammonia gas.

ix. Wipe down all work surfaces at the end of the day with disinfectant. Disinfectant
may be either daily remake of diluted bleach (1 part household bleach containing
5.25% sodium hypochlorite + 9 parts water) or an equivalent disinfectant.

b.	Waste disposal:

i. Autoclaving: All diluted biological specimens, original biological specimens being
disposed, or consumables which come into contact with biological specimens


-------
Serum Multi-Element ICP-DRC-MS
DLS Method Code: DLS: 3006.8-03	Page 11 of 86

(even diluted or aerosolized). Use sharps containers or special autoclave pans
for broken glass / quartz or items which are puncture hazards (e.g. pipette tips),
(see the "Autoclaving" section of the CDC safety policies and practices manual
located in the laboratory).

ii. Other liquid waste

1.	Waste discarded down sink: Do not discard solutions at the sink having a
pH lower than 5.0 or higher than 11.5 (limits defined by Dekalb County,
GA). Inactivate biological compounds and cellular constituents in mixed
chemical and biological waste, such as the waste carboy of the ICP-MS, by
adding an approved disinfectant (e.g. household bleach at a 1:100 dilution
or equivalent) prior to drain disposal. Flush the sink with copious amounts
of water. Waste from the spray chamber and autosampler rinse station
drain into the same carboy and are handled according to DLS 3500
standard operating procedure for handling corrosive liquid laboratory
waste.

2.	Waste to be picked up by hazardous waste program: Submit request for
hazardous waste removal of all other liquid waste generated in the CDC
laboratory for this method.

5) Instrument and material sources

8. Store at ambient temperature and label appropriately. Expiration date is 1
year from preparation.

e. Standards, calibrators, and QC

i.	Multi-element stock calibration standard

1.	Purpose: All working intermediate calibrators are prepared by dilution of
this stock standard which contains all 3 elements of interest for this
method, per the concentrations listed in Table 3 of Appendix C.

2.	Purchasing from vendors: The multi-element stock standard is typically
purchased as a custom mixture (e.g. part number SM-2107-013 from High
Purity Standards (Charleston, SC)). The vendor must provide
documentation of traceability to the National Institute for Standards and
Technology (NIST). Details of the HPS preparation of the multi-element
stock standard is as follows (per statement on their literature):

3.	Storage: Store the solution at ambient temperature. Expiration date is as
defined by vendor or 1 year from date of opening.

ii.	Diluent for intermediate working calibration standards

1.	Purpose: This diluent is used to dilute stock calibration standards down to
the intermediate working calibration standard concentrations.

2.	Preparation: To prepare 1 L of 2% v/v HNO3:

a.	If not previously dedicated to this purpose, acid wash a 1 L glass, PP,
PMP, or Teflon™ volumetric flask with dilute nitric acid (e.g. 1% v/v)
and >18 MQ-cm water (at least 3 times each). Verify cleanliness
through analysis of rinsate. Dedicate to purpose, if possible.

autosampler of the ELAN® ICP-DRC-MS.

2.	Preparation: To prepare the volumes and concentrations of intermediate
working standards per Table 4 in Appendix C:

a. If not previously dedicated to this purpose, acid wash PP, PMP, or
Teflon™ volumetric flasks with dilute nitric acid (e.g. 1% v/v) and >18


-------
Serum Multi-Element ICP-DRC-MS
DLS Method Code: DLS: 3006.8-03	Page 24 of 86

MQcm water (at least 3 times each). Verify cleanliness through
analysis of rinsate. Label and dedicate to purpose, if possible.

f.	Store at ambient temperature and label appropriately. Expiration is 1
year from the date of preparation. The final concentrations of the 3
elements are listed in Table 4 in Appendix C.

iv.	Working multi-element calibrators

1.	Purpose: The working multi-element calibrators are dilutions of the
intermediate working standards. Analysis of these calibrators provides
each run with a signal to concentration response curve for each analyte in
the method. The concentration of an analyte in a patient serum sample
dilution is determined by comparing the observed signal from the dilution of
the patient serum sample to the response curve from the working multi-
element calibrators.

2.	Preparation: Prepare the volumes and concentrations of the matrix-
matched working standards per Table 7 in Appendix C immediately prior to
analysis.

v.	Base serum

1.	Purpose: This serum pool material will be mixed with the intermediate
working calibrators just prior to analysis to matrix-match the calibration
curve to the serum matrix of the unknown samples.

2.	Collection of serum: A mixture of multiple human serum sources purchased
from Tennessee Blood Services, 807 Poplar Ave., Memphis, TN 38105.
These serum were collected from different anonymous donors are used to
approximate an average serum matrix.

3.	Screening serum: Screen serum sources for metal content and choose
sources which reflect the low-normal population range (see Table 2 in
Appendix C for maximum suggested concentrations).

4.	Preparation and storage:

a. Once screened, mix the serum collections together in a larger
container (i.e. acid washed polypropylene (PP), polymethylpentene


-------
Serum Multi-Element ICP-DRC-MS
DLS Method Code: DLS: 3006.8-03	Page 25 of 86

(PMP), or Teflon™) and stir for 30+ minutes on a large stir plate (acid
wash large Teflon™ stir bar before use).

b.	Dispense into smaller-volume, pre-screened vials for use in the lab.

c.	Label appropriately and store frozen (e.g. < -20° C).
vi. Internal quality control materials ("bench" QC)

1.	Purpose: Internal (or "bench") quality control (QC) materials are used to
evaluate the accuracy and precision of the analysis process, and to
determine if the analytical system is "in control" (is producing results that
are acceptably accurate and precise). They are included in the beginning
and at the end of each analytical run. These pools will need to be
prepared periodically, as supply indicates, by spiking base serum. Prepare
new pools far enough in advance so that both old and new pools can be
analytes together for a period time (preferably at least 20 runs) before
switching to the new quality control materials.

2.	Content: The internal (or "bench") quality control (QC) materials used in
this method are pooled human serum. The serum is spiked, when
necessary, with inorganic, NIST-traceable standards to achieve desired
concentrations. The analyte concentrations in the "low QC" are in the low-
normal concentration range. The analyte concentrations in the "high QC"
are in the high-normal concentration range.

3.	Preparation and storage: Quality control materials can be either prepared
by and purchased from an external laboratory or prepared within the CDC
laboratories. Quality control must always be traceable to the National
Institute for Standards and Technology (NIST). The CDC laboratory
currently prepares its own bench QC materials using the following
procedures:

a.	Collection of serum: Human serum can be purchased from blood
services companies such as Tennessee Blood Services, 807 Poplar
Ave., Memphis, TN 38105.

b.	Screening serum: Screen different bottles for metal content before
mixing together to make 2 separate base serum pools (for preparing
the low and high bench QC materials).

i.	Keep serum at < -20C whenever possible to minimize microbial
growth.

ii.	Choose base serum with concentrations in the low-normal
population range (see Table 10 in Appendix C) for low QC.

Choose base serum with concentrations below the targeted high-
normal population concentration for high QC.

c.	Spiking of serum


-------
Serum Multi-Element ICP-DRC-MS
DLS Method Code: DLS: 3006.8-03	Page 26 of 86

i.	Analyze a sample of each serum pool. Record these results for
future recovery calculations.

ii.	Use these results to determine target analyte concentrations
possible for the pools

iii.	Calculate the volume of single element standards needed to spike
each pool to the desired concentrations.

iv.	While stirring the pools on large stir plates, spike each pool with
calculated volumes of single element standards (all spiking
standards used must be traceable to NIST).

v.	Continue to stir pools for 30+ minutes after spiking, then reanalyze.

vi.	Repeat steps 4 and 5 until all analytes reach target concentrations
keeping track of the total volume of spiking solution added to each
serum pool.

d. Dispensing and storage of serum

i.	Container types: Dispense serum into lot screened containers (i.e.
2 ml_ polypropylene cryovials). If possible, prepare tubes of QC
which have only enough volume for one typical run + 1 repeat
analysis. This allows for one vial of QC to be used per day of
analysis, reducing chances of contamination of QC materials due
to multi-day use.

ii.	Labels: Place labels on vials after dispensing and capping if the
vials are originally bagged separately from the caps. This
minimizes the chance for contamination during the process.

Include at least the name of QC pool (text and bar code), date of
preparation, and a vial number on the labels.

iii.	Dispensing: Dispensing can be accomplished most easily using a
benchtop automatic pipette in continuous cycling dispense mode.
Carry out this process in a clean environment (e.g. a class 100
cleanroom area or hood is preferred to avoid contamination).

1.	Allow serum pool to reach ambient temperature before
dispensing (to prevent temperature gradients possibly causing
concentration gradients across the large number of vials being
dispensed and to prevent condensation problems during
labeling of vials).

2.	Attach tubing to the syringe of the benchtop automatic pipette
with a length of clean Teflon™ tubing long enough to reach
into the bottom of the carboy while it is sitting on the stir plate.

3.	Check cleanliness of benchtop automatic pipette before use
by analyzing 1-2% (v/v) HNO3 which has been flushed through


-------
Serum Multi-Element ICP-DRC-MS
DLS Method Code: DLS: 3006.8-03	Page 27 of 86

the pipette with a portion of the same solution which has not
been through the pipette.

4.	Approximately one hour before dispensing begins,

a.	With the large stir plate close to the left side of the pipette,
begin stirring the serum pool to be dispensed.

b.	Also during this time, flush the pipette syringe(s) with
serum from the pool to be dispensed. Place the ends of
the tubing attached to both the sample and dispensing
syringes into the carboy of serum so that serum won't be
used up during this process. Secure both ends of tubing in
the carboy with Parafilm so they will not come out during
the flushing process.

5.	After dispensing the serum into the vials, cap the vials and
label them. Placing labels on vials after capping minimizes the
chance for contamination during the process.

iv.	Homogeneity testing: After dispensing, check homogeneity of
analyte concentrations in pool aliquots by analysis of every Nth
sample dispensed (where N ~20 - 50 depending on the pool size).
Sample more heavily from the beginning and the ending portions
of the tubes dispensed (these are the regions where most
homogeneity problems occur). Keep samples pulled for
homogeneity analysis in the sequence that they were dispensed
for the purpose of looking for trends in concentrations. Once
dispensed and homogeneity has been shown to be good
throughout the tubes of a pool, store tubes at < -20°C and pull
tubes out as needed for analysis.

v.	Storage: Store serum pools long term at < -20°C. Short term
storage (up to several days) is permitted at refrigerated
temperatures (~2-8°C).

f. Optimization solutions
i. PRC optimization:

1. Purpose: For periodic testing of the DRC cell parameters. Procedure
requires at a minimum a blank (i), an analyte solution (ii), a blank with
interference (iii), and an analyte and interference containing solution (iv).

a.	Solutions for testing elimination of 36Ar14N2 plasma interference on

iv.	Base serum in diluent (1+29) + 90 |jg/L Se + 100 mg/L Ca

2. Preparation: To prepare these DRC optimization solutions, use the 10 pg/L
Ga, 2% (v/v) HNOs, 5% Ethyl Alcohol, 0.01% Trion X-100™ diluent as
described in section 6 (same as used to prepare serum samples for
analysis). Prepare different volumes by adding proportionally larger or
smaller volumes of solution constituents. Interference concentrations can
be prepared higher as needed by adjusting the volume of this spike. Keep
interference spike volume small (<0.3 mL) using a high concentration stock
solution (i.e. 1000 mg/L). The Ca spike has to be 0.5 mL because a stock
solution at a concentration higher than 10,000 mg/L is not available. In this
case, 0.5 mL of >18 MQ-cm water is added to the non-spike solutions as
well. Analyte concentrations can be made higher if needed for sensitivity
reasons by preparing a higher concentration calibrator.

7) Analytical instrumentation and parameters

(see Section 5 for details on hardware used, including sources)
a. Instrumentation and equipment setup:
i. Configuration for liquid handling
See Figure 1 in Appendix C for an example setup.

1.	Tubing for liguid sample uptake:

a.	Probe-to-peristaltic pump tubing: Use of a 'peristaltic to Teflon tubing
adapter' is recommended to prevent damage to small i.d. tubing when
making connections.

b.	Nebulizer-to-peristaltic pump tubing: It is recommended to use quick
connection fittings on either end of the PFA tubing: a plug which
pushes inside the liquid port of the nebulizer and a 'peristaltic to Teflon
tubing adapter' to prevent damage to small i.d. tubing when making
connections.

2.	Spray chamber waste removal

Use of a 'peristaltic to Teflon tubing adapter' is recommended to prevent
damage to small i.d. tubing when making connections.

a.	Between spray chamber and peristaltic tubing:

i.	Spray chambers with threaded connection: Use vendor-supplied
threaded connector on base of chamber, connecting tubing directly
to peristaltic pump tubing through a PEEK adapter or directly.

ii.	Spray chambers without threaded connection: Use of specialized
push-on connectors available from various vendors (like UFT-075
from Glass Expansion, Pocasset, MA) are preferred for safety
reasons to direct connection of PVC tubing (e.g. 1/8" i.d. x %" o.d.).

b.	Between peristaltic pump tubing and waste container: Connect 1/8"
i.d. x %" o.d. PVC tubing to the white/black peristaltic pump tubing
using a tubing connector (PerkinElmer item # B3140715). Connect the
free end of the PVC tubing to the lid of the waste jug. The waste jug
must be in a deep secondary containment tray in case of overflow
(large enough to hold 110% of waste container volume).


-------
Serum Multi-Element ICP-DRC-MS
DLS Method Code: DLS: 3006.8-03	Page 31 of 86

3. Rinse solution for autosampler:

a.	Rinse solution jug: Leave one of the caps on the top of the rinse jug
loose to allow air venting into the jug as liquid is removed. Otherwise
the jug will collapse on itself as the liquid is removed and a vacuum is
created inside. Use secondary containment tray.

b.	Rinse solution uptake to autosampler rinse station: Use tubing of
different lengths and inner diameters between the rinse solution
container and the autosampler rinse station to control uptake rate of
rinse solution. These can be obtained from the autosampler
manufacturer, their distributors, or custom built in the lab. Optimize
these factors along with fill time in the software so that waste of rinse
solution is minimized and rinse station does not go empty.

c.	Autosampler rinse station waste removal: Gravity drain of waste to the
waste container is sufficient. Use minimum drain tubing to make this
connection. If this tube is too long, the rinse station will not drain
properly.

ii. Gas delivery and regulation

1.	ICP-MS modifications:

a. Plastic tubing between mass flow controllers and dynamic reaction cell
have been replaced with stainless steel. Stainless steel tubing is
preferred between the reaction gas cylinder/regulator and the back of
the ICP-MS instrument.

2.	Argon gas: Used for various ICP-MS functions including plasma and
nebulizer.

a.	Regulator for argon source (if a dewar): Set delivery pressure of this
regulator at least 10 psi higher than the delivery pressure of the step-
down regulator to allow for pressure drop across tubing that stretches
to the instrument.

b.	Step down regulator (if source of argon is a bulk tank): Place this
single stage regulator in the lab so that incoming argon pressure can
be monitored and adjusted. Set delivery pressure to 10 psig above the
delivery pressure of the filter regulator on the ICP-MS.

c.	Filter Regulator at ICP-MS: Single stage "argon regulator filter kit"
supplied with the ICP-DRC-MS. Set the delivery pressure depending
on the instrument setup:

i.	ELAN with a 0-60psi gauge on the filter regulator: 52±1 psi when
plasma is running (need 0-150 psi regulator if using a PolyPro or
PFA nebulizer made by Elemental Scientific Inc).

ii.	ELAN with a 0-150psi gauge on the filter regulator: 90-100 psi
when plasma is running.

iii. Chiller / heat exchanger: Refrigerated chiller (for ELAN® 6100 DRCP|US
instruments) or heat exchanger (for ELAN® DRC II instruments). For
refrigerated chiller, set temperature control to 18°C.

b. Parameters for instrument and method:

See Tables and Figures in Appendix C for a complete listing of the instrument

and method parameters and software screen shots.

8) The run: quality, execution, evaluation, and reporting

a.	Bench QC, reference materials, and calibration verification:

i.	Bench "QC": Analysis of bench QC permits assessment of methodological
imprecision, determination of whether the analytical system is 'in control' during
the run, and assessment of time-associated trends. Before QC materials can
be used in the QC process, they must be characterized by at least twenty (20)
analytical runs to determine appropriate QC parameters.

Bench QC pool analyte concentrations in this method span the analyte
concentration range of the calibrators including "low-normal" ('Low QC') and
"high-normal" ('High QC') concentrations.

In each analytical run the analyst will test each of the two bench QC samples
two times, subjecting them to the complete analytical process. Bench QC pool
samples are analyzed first in the run after the calibrators but before any patient
samples are analyzed. This permits making judgments on calibration linearity
and blank levels prior to analysis of patient samples. The second analysis of
the bench QC pools is done after analysis of all patient samples in the run
(typically 20-30 patient samples total when analyzing for all elements in the
method) to ensure analytical performance has not degraded across the time of
the run. If more patient samples are analyzed on the same calibration curve
after the second run of the bench QC, all bench QC must be reanalyzed before
and after the additional samples. For example, the schemes shown in Table 5
in Appendix C are both acceptable ways to analyze multiple consecutive
"runs".

ii.	Reference materials: Use standard reference material (SRM, e.g. SRM
1598A) from the National Institute of Standards and Technology (NIST) to
verify method accuracy. Use previously characterized samples from
proficiency testing program or commercially-produced reference materials
when NIST SRMs are unavailable.

iii.	Calibration verification: The test system is calibrated as part of each analytical
run with NIST-traceable calibrators. These calibrators, along with the QCs and
blanks, are used to verify that the test system is performing properly.

b.	Perform, evaluate, and report a run

i. Starting the equipment for a run


-------
Serum Multi-Element ICP-DRC-MS
DLS Method Code: DLS: 3006.8-03	Page 33 of 86

1.	Power on the computer, printer, autosampler, and instrument computer
controller.

2.	Peristaltic pump: Set proper tension on peristaltic pump tubing.

3.	Software: Start software for the ICP-MS and autosampler control.

4.	Daily pre-ignition maintenance checks: Perform and document daily
maintenance checks (e.g., Ar supply pressure, interface components
cleanliness and positioning, interface pump oil condition, vacuum pressure,
etc.).

5.	Place probe in adequate volume of rinse solution: Send the autosampler
probe to a rinse solution (e.g. autosampler rinse station).

6.	Start the plasma

7.	Start the peristaltic pump: Start the pump running slowly, making sure that
the rotational direction is correct for the way the tubing is set up.

8.	Warm-up time: Allow warm-up time suggested by the manufacturer for the
ICP-MS (e.g. RF generator) after igniting the plasma. There will be
another warm-up time (or "stability time") for the DRC later in this
procedure.

9.	Daily performance check: Perform and document a daily performance
check and any optimizations necessary.

Save new parameters to the "default.tun" and "default.dac" files.

10.	Readying the instrument for quick-start analysis: Leave the plasma
running to eliminate the need for an initial instrument warm-up period
and/or a DRC stabilization period as long as appropriate planning is made
for sufficient solution supply and waste collection. Analysis of conditioning
samples (diluted serum matrix) can also be scheduled to occur at roughly a
predetermined time. Accomplish this by setting up multiple sample
analyses with extended rinse times (e.g. one analysis with a 1600s rinse
time will take approximately 30 minutes to complete). Initial samples would
be non-matrix, while final samples would be diluted matrix for conditioning.
If running a DRC-only method during these scheduled analyses, the ICP-
MS will remain in DRC-mode for approximately 45 minutes without
depressurizing the cell. Prepare working dilutions of serum materials close
in time to analysis so that they are not more than 7 hours old when
analyzed (see Appendix B, ruggedness test 5).

11.	Software setup for analysis:

a. Workspace (files and folders): Verify and set up the correct files and
data directories for your analysis (See Table 1 in Appendix C for
defaults).


-------
Serum Multi-Element ICP-DRC-MS
DLS Method Code: DLS: 3006.8-03	Page 34 of 86

b. Samples / batch window: Update the software to reflect the current
sample set. Use a bar code scanner to input data whenever possible.
See Table 1 in Appendix C for times and speeds.

1. Serum vs. aqueous method files:

a.	The difference: There are two method files for this one
method (see Table 1 in Appendix C). It is necessary to use
both to accomplish each run because the current
PerkinElmer software will not allow for more than one blank
per method file. The ONLY DIFFERENCE between these
two files is on the Sampling tab where one lists the
autosampler positions of the serum blank and serum
calibrators (the "sblk" method file) and the other lists the
autosampler position of the aqueous blank (the "aqblk"
method file).

b.	Use: The ONLY TIME when it matters which of these files
is used is when the measurement action includes "Run
blank" or "Run standards". When the measurement action
is only 'run sample', it does not matter whether the "sblk" or
"aqblk" method file is used. Analysts typically follow the
pattern below, however, for the sake of consistency and as
a reminder of which blank must be used for which type of
sample. See Table 6 in Appendix C.

i.	The "sblk" method file: Use to analyze the initial serum
blank (blank for the calibration curve), the serum
calibrators, and the serum blank checks at the very
beginning of the run. The serum blank method defines
the autosampler location of the serum blank and the
serum calibrators.

ii.	The "aabllc" method file must be used to analyze all QC
materials and patient samples. The aqueous blank
method defines the aqueous blank in autosampler
location.

ii. Preparation of samples for analysis (See Table 7 in Appendix C)

1.	Thaw serum samples; allow them to reach ambient temperature.

2.	If instrument stability in DRC mode requires it, prepare 50mL+ of a junk
serum sample to be analyzed repeatedly before the beginning of the run
to achieve a stable analyte-to-internal standard ratio. Time to reach
stability is instrument-specific but 1-1.5 hours is typical (~18
measurements of the 3 element serum method can be made in 1 hour).
See Table 6 in Appendix C for example of setup in the Samples/Batch
window.


-------
Serum Multi-Element ICP-DRC-MS
DLS Method Code: DLS: 3006.8-03	Page 35 of 86

NOTE: Selenium is not stable in the diluted sample for more than 7
hours. Diluted serum must be analyzed within 7 hours of
preparation (see ruggedness parameter test 5 in Appendix B for
details)

3. Prepare the following solutions into pre-labeled containers using the
benchtop automatic pipette. See Table 7 of Appendix C for a summary
of sample preparation.

Prepare samples in the cleanest environment available to prevent trace
element contamination and an environment which provides personnel
protection (e.g. Class II, Type A/B3 biological safety cabinet).

a.	Aqueous blank: Prepare at least two aqueous blanks. One will be the
actual reagent blank for patient and QC samples and the other will be
a backup ("Aqueous Blank Check") in case the original aqueous blank
is unusable.

b.	Calibrators: Prepare the working calibrators (S0-S5). Prepare at least
three separate tubes of SO. One of these SO preparations will be the
zero standard (serum blank) for the calibrators; the other two will be
analyzed after the last calibrator to verify washout.

c.	Patient and QC samples: Before taking an aliquot for analysis,
homogenize the sample (e.g. vortex for 3-5 seconds).

After preparation, mix and cover the diluted samples. Place prepared
dilutions on the autosampler of the ICP-MS in the order corresponding to
the sequence setup in the ICP-MS software.

Original serum samples are not compromised by staying at ambient
temperature during the work day. However, store long-term at < -20 °C.

iii.	Start the analysis using the ICP-MS software.

iv.	Monitor the analysis in real-time as much as possible. If necessary, leave the
run to complete itself unattended as long as appropriate planning is made for
either overnight operation or Auto Stop (see below).

Monitor the analysis for the following:

1.	Verify proper operation of the instrument (sample reaching nebulizer in
correct timing, autosampler arm moving properly, etc...).

2.	Verify that background signal from instrument and reagents are low.

Helpful checks when diagnosing high background problems include:

a.	>18 MQ-cm water to be used in Aq Blank Checks and dilutions.

b.	Diluent before and after being flushed through the benchtop automatic
pipette.

If contamination is observed from the pipette, flush the pipette with
>500 ml_ of nitric acid solution (< 5% v/v HNO3) and retest.


-------
Serum Multi-Element ICP-DRC-MS
DLS Method Code: DLS: 3006.8-03	Page 36 of 86

c. Comparison with other instruments.

3.	Verify analyte/internal standard ratio stability (esp. DRC measurements)

The net intensity (analyte / internal standard ratio) of the measurements
made while stabilizing the DRC can be evaluated to determine the
readiness of the system to begin analysis. Continual trending in this ratio
indicates that unwanted instrument drift will occur within the run.

4.	Verify calibration curves meet R2 requirements (minimum of 0.98, typically
0.99 to 1.000).

5.	Verify bench QC results within the acceptable limits.

If an analyte result for the beginning QC material(s) falls outside of the ±
3SD limits, then the following steps are recommended:

a.	Evaluate the blank results.

b.	Evaluate the reproducibility of the 3 replicates within the
measurements.

c.	Evaluate the consistency of the internal standard across the
measurements (especially the calibrators).

d.	Evaluate calibration curves. If a particular calibrator is obviously in
error, it can be re-analyzed as a sample (old or new dilution) and
incorporated into the curve through data reprocessing as a calibrator.
As a last resort, a single calibration point per analyte between or
including S2 and S4 can be removed from the curve. Follow-up
repeated problems with calibrators with appropriate corrective actions
(e.g. re-preparation of intermediate working calibration standards or
troubleshooting instrument parameters).

e.	Prepare a fresh dilution of the failing QC material (same vial) and
reanalyze it to see if the QC dilution was not properly made.

f.	Prepare a fresh dilution of the failing QC material (unused vial) and
analyze it to see if the QC vial had become compromised.

g.	Prepare and analyze new working calibrators.

h.	Test a different preparation of intermediate working calibration
standards.

If these steps do not result in correction of the out-of-control values for QC
materials, consult the supervisor for other appropriate corrective actions.

6.	Verify good precision among replicates of each measurement.

7.	Verify consistent measured intensities of the internal standards.

Some sample-to-sample variations are to be expected, however, intensities
drifting continuously in one direction resulting in failing results for ending


-------
Serum Multi-Element ICP-DRC-MS
DLS Method Code: DLS: 3006.8-03	Page 37 of 86

QC indicate the instrument needs additional pre-conditioning before the run
or environmental conditions are changing too much around the instrument.

8. Verify elevated patient results.

Refer to Figure 14 in Appendix C for flowchart.

a.	Confirming an elevated concentration: Repeat for confirmation any
sample having a concentration greater than the 1UB threshold (see
Table 9 in Appendix C).

b.	Dilution of a sample to within the calibration range: Repeat in duplicate
with extra dilution any sample having a concentration greater than the
highest calibrator to bring the observed result within the concentration
range of the calibrators (see Table 8 in Appendix C).

c.	Confirming proper washout after an elevated sample: When monitoring
the analysis in real-time, if a sample concentration is greater than
standard 5 + 10% (see Table 4 in Appendix C), do the following to
verify that the run is still in control for low concentration samples before
proceeding with analysis.

i.	Stop run following elevated sample

ii.	Verify that the run is still in control for lower concentration samples
before proceeding with analysis. Analyze 2 serum blank checks
followed by a low bench QC washout check. If the low bench QC
wash check is not in control (within ± 3SD limits), repeat these 3
check samples until washout is verified before proceeding with
analysis.

Example:

3006 sblkchk Washl
3006 sblkchk Wash2
LSXXXXX Wash

iii.	If the run is not verified in-control for low concentration samples
before the next samples are analyzed, see Section 8.b.viii.2. for
directions.

v.	Instrument cleaning between consecutive runs: In between consecutive runs,
aspirate >18 MQ-cm water through the sample introduction system for
approximately 30 minutes at peristaltic pump speed similar to that used in the
analysis. This assists cleaning out the sample introduction system to prevent
clogging.

vi.	Overnight operation or using auto stop: Ensure sufficient solution supply and
waste collection during unattended operation. Turn on the AutoStop feature of
the ICP-MS software. Delay the shutdown at least 10 minutes (use peristaltic
pump speed approximately that of the method wash) to rinse the sample
introduction system of serum matrix before turning off the plasma. It will be


-------
Serum Multi-Element ICP-DRC-MS
DLS Method Code: DLS: 3006.8-03	Page 38 of 86

necessary to replace the sample peristaltic pump tubing the next day since it
will have been clamped shut overnight.

vii.	Records of results: Run results will be documented after each run in both
electronic and paper form.

1.	Electronic records: Transfer data electronically to the laboratory information
system. When keyboard entry must be used, proofread transcribed data
after entry.

a.	Export data from the ICP-MS software using "original conditions" or
files and folders used during the analysis. Use descriptive report
filenames (e.g. 2005-0714a_group55.txt). In the ICP-MS software
under "Report Format" (METHOD window, REPORT tab) choose the
"Use Separator" option, and under the "File Write" Section choose
"Append."

b.	Move the generated .TXT data file to the appropriate subdirectory on
the network drive where exported data are stored prior to import to the
laboratory information management system.

c.	Import the instrument file into the laboratory information system with
appropriate documentation (e.g. instrument ID, analyst, calibrator lot
number, and run or sample specific comments).

2.	Paper records: Printed run sheets must be documented with

i.	Analyst initials

ii.	Instrument ID

iii.	Date of analysis and run # for the day

viii.	Analyst evaluation of run results:

1. Bench quality control: After completing a run, and importing the results into
the laboratory information system, evaluate the run bench QC according to
laboratory QC rules. The QC limits are based on the average and standard
deviation of the beginning and ending analyses of each of the bench QC
pools, so it will not be possible to know if the run is in control until
statistically reviewed.

a. Quality Control Rules: The SAS program applies the division QC rules
to the data as follows:

i.	If both QC run means (low and high bench QC) are within 2Sm
limits and individual results are within 2Si limits, then accept the
run.

ii.	If 1 of the 2 QC run means is outside a 2Sm limit - reject run if:

1. Extreme Outlier - Run mean is beyond the characterization
mean +/- 4Sm


-------
Serum Multi-Element ICP-DRC-MS
DLS Method Code: DLS: 3006.8-03	Page 39 of 86

2.	1 3S Rule - Run mean is outside a 3Sm limit

3.	2 2S Rule - Both run means are outside the same 2Sm limit

4.	10 X-bar Rule - Current and previous 9 run means are on
same side of the characterization mean

iii. If one of the 4 QC individual results is outside a 2Si limit - reject
run if:

1. R 4S Rule - Within-run ranges for all pools in the same run
exceed 4Sw (i.e., 95% range limit)

Note: Since runs have multiple results per pool for 2 pools, the R 4S
rule is applied within runs only.

Abbreviations:

Si = Standard deviation of individual results (the limits are not shown
on the chart unless run results are actually single
measurements).

Sm = Standard deviation of the run means (the limits are shown on the
chart).

Sw = Within-run standard deviation (the limits are not shown on the
chart).

b. Implications of QC Failures: If the division SAS program declares the
run out of control" for any analyte, use the following to determine the
implications on usability of the data from the run.

i.	If only one analyte of the three fails bench QC, then report results
for the other two which passed bench QC.

ii.	If two analytes of the three fail bench QC, then no results are
reportable from the run. Investigate the cause of QC failures and
repeat the run with the appropriate corrective action.

2. Patient results:

a. Concentrations outside of the normal range (refer to Figure 14 in
Appendix C for flowchart on handling elevated concentration samples):

i. Boundaries requiring confirmatory measurement:

1. Results outside of the first (1 LB or 1UB) or second (2LB or
2UB) boundaries.

The concentrations assigned to 2LB, 1LB, 1UB, and 2UB for
an element is determined by study protocol but default
concentrations are in Table 9 in Appendix C.

a. Results lower than the first lower boundary or greater than
the first upper boundary (1 UB): Confirm by repeat analysis


-------
Serum Multi-Element ICP-DRC-MS
DLS Method Code: DLS: 3006.8-03	Page 40 of 86

of a new sample preparation any concentration observed
lower than the 1 LB or greater than the 1UB. Report the first
analytically valid result, as long as the confirmation is within
10% or 3SD of the characterized bench low QC. Continue
repeat analysis until a concentration can be confirmed.

b. Analyst reporting of results outside of the normal range:
Report any patient results confirmed to be less than the
second lower boundary (2LB) as an "unusually low result" or
greater than the second upper boundary (2UB) as an
"elevated result".

2. Results greater than highest calibrator: Samples that exceed
the high calibrator must be prepared with minimum extra
dilution in duplicate to bring the observed result within the
calibration range (< S5). Report the first analytically valid
result (i.e. the first one within the calibration range), as long as
the confirmation is within 10%. Continue repeat analysis until a
concentration can be confirmed.

ii. Concentrations reguiring verification of washout: after a result is
observed that is greater than the highest concentration validated
for washout, do the following:

1.	If the run was verified to be in control for lower concentration
samples before subsequent sample analysis was performed,
no further action is required.

2.	If the run was not verified to be in control for lower
concentration samples before subsequent sample analysis
was performed, confirm by re-analysis the results for the 2
samples immediately following the elevated sample. Report
the results if they confirm the initial results within ±10% or
±3SD of the low bench QC, whichever is greater.

b. Unacceptable measurement reproducibility: If the range of the three
replicate readings (maximum replicate concentration value - minimum
replicate concentration value) for a single sample analysis is greater
than the range maximum criteria listed in Table 9 of Appendix C and
the range of the three replicate readings is greater than 10% of the
observed concentration, do not use the measurement for reporting.
Repeat the analysis of the sample.

ix. Submitting final work for review: All analyses must undergo quality control and
quality assurance review. After appropriately documenting the run in the
laboratory information system (e.g. sample and run QC, and run and sample
comments), inform the first level reviewer of the completed work and submit
any printed documentation.

Serum Multi-Element ICP-DRC-MS
DLS Method Code: DLS: 3006.8-03	Page 41 of 86

9)	Routine equipment maintenance and data backups

Maintenance activities will be documented in the instrument logbook.

a.	Equipment maintenance:

Analysts are expected to regularly evaluate the need for, and when necessary,
perform cleaning, replacement, or re-positioning of components in ICP-MS the
sample introduction system, interface, ion optics region, and equipment required
resources (e.g. autosampler, exhaust, compressed gases, and coolant).
Frequency of equipment maintenance will be dependent on instrument
throughput.

b.	Parameter optimizations:

Analysts are expected to optimize instrument parameters.

PRC optimizations: DRC conditions (cell gas flow rate and RPq value) can be
verified by analyzing the DRC optimization solutions (see Section 6.f.i) as
needed to ensure proper reduction of potential ICP-MS interferences.

c.	Data backup:

Data on the instrument computer will be backed up via two backup routines.

Files used and produced by the ICP-MS in analyzing samples will be backed up
and kept a minimum of two years after analysis.

i.	Daily backups to secondary hard drive: Program automatic backups of the
relevant computer files to occur each night onto a secondary hard drive to
prevent loss of data from failure of primary hard drive.

ii.	Weekly backup: Backup relevant computer files weekly either to secondary
hard drive which is remote to the laboratory or to removable media which will
be placed remote to the laboratory for retrieval in the case of catastrophic data
loss elsewhere.

10)	Reporting thresholds

a.	Reportable range:

Serum element concentrations are reportable in the range between the method
LOD and the high calibrator times the maximum permitted extra dilution (see
Table 8 of Appendix C).

Serum multi-element values are reportable in the range between the method
LOD and the highest calibrator (see 'calibrator concentrations' in Table 1 of
Appendix C) times the maximum validated extra dilution (see Table 7 of
Appendix C). Above the highest calibrator, extra dilutions are made of the serum
sample to bring the observed concentration within the calibration range.

b.	Reference ranges (normal values):

In this method the 95% reference ranges (see Table 10 in Appendix C) for these
elements in serum fall within the range of the calibrators.


-------
Serum Multi-Element ICP-DRC-MS
DLS Method Code: DLS: 3006.8-03	Page 42 of 86

c. Action levels:

There is no routine notification for levels of every analyte determined with this
method. The protocol for supervisors reporting elevated results to medical
personnel is defined according to the study protocol.

11)	Method calculations

a.	Method limit of detection (LOP):

The method detection limits for elements in serum specimens are defined as 3
times so, where so is the estimate of the standard deviation at zero analyte
concentration. So is taken as the y-intercept of a linear or 2nd order polynomial
regression of standard deviation versus concentration (4 concentration levels of
the analytes in serum each measured 60 times across at least a 2-month
timeframe). Method LODs are re-evaluated periodically.

b.	Method limit of quantitation (LOQ):

The Division of Laboratory Sciences does not currently utilize limits of
quantitation in regards to reporting limits [5],

c.	QC limits:

Quality control limits are calculated based on concentration results obtained in at
least 20 separate runs. It is preferable to perform separate analyses on separate
days and using multiple calibrator lot numbers, instruments, and analysts to best
mimic real life variability. The statistical calculations are performed using the
SAS program developed for the Division of Laboratory Sciences).

12)	Alternate methods for performing test and storing specimens if test system
fails

If the analytical system fails, setup analysis on other ICP-MS instrument, if available.
If no other instrument is available, store the specimens at < -20 °C until the analytical
system can be restored to functionality.

13)	Method performance documentation

Method performance documentation for this method including accuracy, precision,
sensitivity, specificity and stability is provided in Appendix A of this method
documentation. The signatures of the branch chief and director of the Division
of Laboratory Sciences on the first page of this procedure denote that the
method performance is fit for the intended use of the method.

a. Ruggedness parameter test #1

Evaluate the impact on analysis results if the set RF power is increased to
1600W (instrument maximum) or decreased to 1150W (by 20%).

i.	Test details: Three different PF power settings were tested in separately
prepared, consecutive runs on the instrument without turning off the plasma. At
least 15 minutes stabilization time was allowed between each run after the RF
power was changed. Each run had 20 "Junk serum" samples analyzed between
the beginning and ending QC. All other method parameters were kept per
method.

1.	Run #1: Method default with RF power 1450W.

2.	Run #2: Decreased RF power by 20% to 1150W.

3.	Run #3: Increased RF power to instrument maximum, 1600W.

4.	Run #4: Increased RF power to 1525W.

ii.	Results: See Ruggedness Table 1.

iii.	Conclusion: Results are not compromised by changes in RF power within the
range of 1150Wto 1600W.

e. Ruggedness parameter test #5

Method descriptions and SOP assume preparation and analysis on same day.
Evaluate the impact on analysis results if the analytical run is prepared to
analyze but circumstances do not allow for analysis to occur until 24 or 48 hours
later.

i.	Test details (Part 1: 24-hour increments): All runs had 20 "Junk serum" samples
analyzed between the beginning and ending QC of each run, making each a
normal length run. All other method parameters were kept per method.

1.	Day 1: Prepare samples for analysis in triplicate (calibrators, blanks, QC
and reference materials in three separate sets of tubes). Set '#1 was
analyzed immediately. Sets #2 and #3 were capped and stored at ambient
temperature.

2.	Day 2: Prepare a new run (set #4). Analyze set #4 immediately, then set
#2.

3.	Day 3: Prepare a new run (set #5). Analyze set #5 immediately, then set
#3.

ii.	Test details (Part 2 within 24 hrs.): Due to the observations in test #1 for
selenium, a shorter time frame was examined in part two of this test.

1.	Sample Preparation: Seven preparations of the low bench QC serum
material were made at the beginning of the experiment. Each of these
seven preparations were 4x the normal preparation volume (4 preparations
into each vial).

2.	Sample Analysis: Four consecutive runs of the serum method were then
carried out. Each run included blanks, calibrators, and run judge QC
(beginning and ending) prepared immediately prior to the beginning of
each run and seven preparations of the low bench QC prepared
immediately prior to the beginning of each run. The seven preparations of
the low bench QC pool prepared before the first run were measured within
each run alternated with the freshly prepared low bench QC sequentially
throughout the run.

iii.	Results: See results in Ruggedness Table 5 and Ruggedness Table 6.

iv.	Conclusions:

1. Test part 1: The serum ICP-MS method is rugged for Zn and Cu to delays
in analysis of samples after preparation for up to 48 hours and not rugged
for Se to delay in analysis of samples after preparation for even 24 hours.
The serum ICP-MS method is rugged for Zn and Cu to delays in analysis of
samples after preparation for up to 48 hrs (see part 1).

2. Test part 2: The method is only rugged to delays in analysis for selenium
for up to approximately 7 hours (one 90 patient sample run, or two 40

f. Ruggedness parameter test #6

Evaluate the impact on observed concentration if an extra dilution is performed
on the sample relative to the calibration standards.

i.	Test details: A large serum sample, spiked to elevated analyte concentrations,
was prepared for analysis each day for 4 days.

1.	Day 1: A large serum sample was spiked to elevated concentrations using
single element standards and mixed well. The spiked sample was then
prepared for analysis to dilution levels of 2x, 5x, 10x, and 20x using >18
MQ-cm water as the makeup liquid.

2.	Day 2: The spiked sample prepared on Day 1 was prepared for analysis to
dilution levels of 2x, 5x, 10x, and 20x using >18 MQ-cm water as the
makeup liquid.

3.	Day 3: The spiked sample prepared on Day 1 was prepared for analysis to
dilution levels of 2x, 5x, 10x, and 20x using >18 MQ-cm water as the
makeup liquid.

4.	Day 4: The spiked sample prepared on Day 1 was prepared for analysis to
dilution levels of 2x, 5x, 10x, and 20x using >18 MQ-cm water as the
makeup liquid.

ii.	Results: See Ruggedness Table 7, Ruggedness Table 8, and Ruggedness
Table 9.

iii.	Conclusion: SCU results are not unacceptably affected by the matrix difference
in the dilution with >18 MQ-cm water when performing a 2x, 5x or 10x dilution.
However, the average observation of the 20x dilution is affected more than is
acceptable (>10% bias with noticeable impact on reproducibility).

SSE results are not unacceptably affected by the matrix difference in the dilution
with >18 MQ-cm water when performing a 2x or 5x dilution. However, the
average observation of the 10x and 20x dilutions are affected more than is
acceptable (>10% bias with noticeable impact on reproducibility).

SZN results are not unacceptably affected by the matrix difference in the dilution
with >18 MQ-cm water when performing a 2x, 5x or 10x dilution. However, the
average observation of the 20x dilution is affected more than is acceptable
>10% bias with noticeable impact on reproducibility).

In summary, an extra dilution up to 10x with >18 MQ-cm water was successful
for SCU and SZN with less than a 10% impact on the observed concentration.
However only up to a 5x extra dilution with >18 MQ-cm water was acceptable for
SSE.

If a different total volume is prepared, adjust the volumes for each component proportionally.



These directions are written with the expectation of a 5,000 |jL syringe on the left side and a 250 pi-
syringe on the right side of the benchtop automatic pipettor.

* By splitting the dispense step of diluent into two or more portions, liquids pulled up into the right pipette
tip are flushed out more completely. For example, when preparing a working serum blank (SO) above, do
the preparation in 2 steps: in step 1, dispense 150 |jL intermediate working SO + 2100 |jL diluent; in step
2, dispense 150 |jL base serum + 2100 |jL diluent.

H Extra dilution is performed on serum samples whose concentration is greater than the concentration of
the highest working calibrator listed in Table 8 of Appendix C.

Any extra dilution within these limits can be prepared as long as the 14:15 ratio of diluent to total dilution
volume is maintained. Use of the lowest extra dilution level is preferred to minimize differences between
the calibrators and the samples (i.e. 2x dilution is preferred over 10x if 2x is sufficient to dilute analyte into
the documented linearity range).

Additional flush times and "Max Rinse Time" are default, but can be optimized for best
reduction of elemental carry-over between samples. Tray types can be changed to
allow for different volumes of diluted sample digests. Do not enable 'FAST control'.
Rinse and additional flush times for eliminating carry-over from one sample to the next
while using the minimum amount of rinse solution.

A rinse time of -1 causes the rinse station to be skipped.

A rinse time of 0 causes the probe to only dip into the station, but spends no time there.

Additional flush times can be optimized to keep the rinse station full while not using too
much rinse solution. The inner diameter size of the tubing providing the rinse solution to
the rinse station determines how quickly the station will fill. Various sizes are available
for purchase or can be made in the laboratory.

successive standard has a net intensity greater than the previous
standard). Ensure that net intensity for all standards is positive.

Preparing and monitoring the run

1. Preparing the Run

a.	Thoroughly wash the benchtop automatic pipette probe in-between
samples

b.	Ensure the prepared samples are homogenized (e.g. vortex for 3-5
seconds, or invert 5-10 times) before placing them in the autosampler.

Section 1 - Executive Summary

In October of 2017, the Food Safety and Environmental Stewardship (FSES) program at Oregon State
University (OSU) was contracted by US EPA to evaluate the application of FSES silicone wristband
sampling technologies in a pilot project examining potential exposures related to the use of crumb-
rubber infilled synthetic turf athletic fields. Two sampling sites were identified, one indoor and one
outdoor (described below). Conditioned wristbands installed in FSES standard air cages were deployed
for seven days at each site, approximately one meter above or directly adjacent to the surface of the
synthetic turf, at locations indicated on the associated maps. Additional samplers were deployed at
sampling sites away from the synthetic turf surface. Using duplicate wristband samplers at each site
allowed one to be used for liquid extraction and one for thermal desorption. Additionally, two samplers
were held in their transport bags for the duration of the sampling campaign. These are designated as
trip blanks one and two and their results reported with the field-deployed samplers. Date of deployment
was November 10th through 17th, 2017.

After recovery, one set of field samples and trip blanks were liquid extracted and analyzed for polycyclic
aromatic hydrocarbons (PAHs) and their oxidized derivatives (OPAHs) as well as a broad analyte
presence/absence screen for 1528 chemicals. The replicate set was thermally desorbed and analyzed for
volatile organic compounds (VOCs). Appropriate quality assurance samples were included in every
analytical batch. This report will provide summary statistics of the analytical findings and summaries of
the quality control/quality assurance data produced in support of these results. Four appendices
summarizing the complete analytical findings are appended to this report. Sampling sites are identified
in table one below and fully described in sections 2a and 2b:

Section 2 - Sampling

2a - Indoor site

The indoor sampling site is an indoor athletic practice facility with a wall-to-wall synthetic turf field
approximately 125M long and 62M wide (see figure one). The synthetic turf in this facility is fifteen
months old. Crumb rubber is stored on site and added to the field on a continual as-needed basis. This
field is very well maintained and heavily used by a rotation of different teams who utilize the indoor
facility. Two collocated samplers were deployed in the NW corner (site 1) of the facility. Because of the
difficulty of attaching air cages without disrupting ongoing activities, these samplers were collocated
within a single cage. These samplers are identified as site 1 and site 1 dup (duplicate). A sampler was
also placed at the SE corner (site 2) of the facility. These wristbands were designated site 2. In both site
1 and 2 samplers were directly above the turf bed. Two additional samplers were deployed at sample
site 3, an adjacent atrium with a concrete floor, separated from the turf field by a 3' door and a
secondary partial wall. These samplers are designated site 3. Site 3 was approximately 12 meters from
the turf. In normal use, the door is expected to be opened whenever teams are practicing, which is the
majority of the day. Mean temperature during deployment was 14.6°C ± 1.6°C, with a range from 11.4°C
to 22.7 °C. Figure 1 drawing is not to scale.

2b - Outdoor site

The outdoor site has a synthetic turf field approximately 115M long and 100M wide (see Figure two).
The synthetic turf in this facility is approximately five years old. Crumb rubber is available to the
caretakers and added to the field on an as-needed basis. This field is moderately maintained and heavily
used by a rotation of different activities ranging from organized classes to recreational organizations. In
discussions with facility staff, fresh crumb rubber is added approximately every six months to a year.
Collocated air cages were attached to the perimeter fence on the Northern edge of the field. These
samples are designated as site 4 and site 5. A single air cage was attached to the western perimeter
fence and these samples are designated as site 6. These cages are directly adjacent to the turf and 1
meter above the ground. Because these samplers are adjacent to the field, their theoretical sampling
perimeter will include non-turfed ground. Sample site 7 was on a lamppost adjacent to a concrete
walkway and natural grass area, separated from the turf field by approximately 18 meters. Typical
fall/winter wind patterns are from the SW to the NE,
but vary widely dependent on weather (see table 2).

There was rain recorded on six of the seven days of
deployment, averaging 0.94 cm per day. Mean
temperature during deployment was 9.7°C ± 3.2°C,
with a range from 3.1°C to 22.7 °C. By contrast,
summer surface temperatures on this field have
been measured as high as 65° C. Adjacent roadways
are paved and will see significant traffic during

working hours. Drawing is not to scale.	Table 2. Outdoor site weather parameters

Section 3 - Deployment; Recovery and Processing
3a - Deployment

Air cages were temporarily mounted to facility walls or fences using available support structures. These
cages are designed to allow unrestricted air flow and have been used in multiple successful
environmental sampling campaigns. Conditioned wristbands were transported to the site within
individual PTFE (Teflon) bags. Once sampling cages were installed, conditioned wristbands were
removed from their bags and affixed within the cages using zip ties. Deployment times are provided in
Table 1.

3b - Recovery

After a seven-day deployment, FSES air cages were carefully opened and each wristband removed and
placed in a pre-labeled, air-tight PTFE bag for storage and transport to the FSES laboratory. Air cages
were removed from support structures. Samplers were transported to the FSES laboratory at Oregon
State University where they were logged in and stored as appropriate, described further in SOP 2003.03
Sample Inspection upon Receipt.

3c - Processing and extraction

All samplers were post-deployment cleaned as per SOP 110.00 Cleaning Field Deployed Silicone Passive
Sampling Devices. Samples destined for PAH, OPAH and DRS analysis were extracted as per SOP 419.00
Extraction of Organic Compounds from Silicone Passive Sampling Devices. Wristbands for VOC analysis
were thermally desorbed as per SOP 422.0 Determination of Volatile Organic Compounds (VOCs) using
thermal desorption purge and trap interfaced with El GC/MS.

-------
Section 4 - Analytical Determinations

Aliquots from each ethyl-acetate extract were injected on triple-quadrapole (PAHs; Agilent 7890/7000C
GC/MS/MS) or single quadrapole (OPAHs and DRS; Agilent 6890/5975 GC/MS) gas chromatograph mass
spectrometers as per SOP 418.00 Determination of Parent and Alkyl Substituted PAHs by GC-MS/MS,
SOP 414.00 Determination of Oxygenated Poiycyciic Aromatic Hydrocarbons (OPAHs) using GC/MS or
SOP 423.00 Multiple Analyte Screen by GC-MS and deconvolution software as appropriate.

Aliquots from the thermal tubes were analyzed by SOP 422.00 Determination of Volatile Organic
Compounds (VOCs) using thermal desorption purge and trap interfaced with El GC/MS (Agilent
6890/5975 GC/MS). Each analytical run was individually quantified and all peak values manually
confirmed. Additional quality control samples were run with each analytical batch. The results of these
quality control analyses will be presented with each analytical method summary below. Additional
method parameters including oven profiles, flow rates and instrument specifics are provided within the
previously supplied SOPs (approved 12/4/17).

Analytical effort associated with this project generated over 1,100 quantified chemical data points and
over 15,000 chemical presence/absence determinations. Additionally, over 2,100 quality control data
points were rigorously quantified and reviewed.

All field samples were analyzed on all methods with QC that met applicable DQOs defined in each SOP.

-------
Section 5 - Results

Four appendices are associated with this document. They are provided in PDF and Excel formats. The
appendices correspond to individual client reports for:

1)	PAHs by GC-MS-MS

2)	OPAHsbyGC-MS

3)	Multiple Analyte Screen by GC-MS and deconvolution software (DRS)

4)	Volatile Organic Compounds (VOCs) by thermal desorption

Continuing calibration (CV) quality control samples were analyzed within each analytical batch as
defined in our SOPs. All CVs meet the data quality objectives outlined in each of our SOPs unless
otherwise indicated. FSES generated instrument blanks (IB), field blanks (FB) and lab-process blanks (LB)
meet DQOs defined in our SOP. Background subtraction using values derived from LBs are designated
with a "B" flag in the client report. Method-specific summations are provided by tabulating the QC
performed for each method and designated Quality Control Summary.

Reported concentration units are ng/g wristband for all methods except DRS, which is reported as
presence/absence.

As further detailed in our Quality Assurance Program Plan, all samples and quality control samples
were reviewed by the Senior Chemist and reviewed and approved by the Program Director.
