I.      Introduction

The research study, "Children's Total Exposure to PersistentPesticides and Other Persistent Organic
Pollutants," (CTEPP) is a pilot-scale project involving about 260 children, which investigates the
possible exposures that young children may have to common  contaminants in their everyday
surroundings. These contaminants include several pesticides, phenols, polychlorinated biphenyls,
polycyclic aromatic hydrocarbons, some of which are suspected of being endocrine disrupters. The
targeted compounds are persistent in the indoor and sometimes the outdoor environments, so that
very low levels may exist in the children's surrounding microenvironments and provide a source of
chronic, non-acute exposure.   The  primary purposes  of the research are  to  increase our
understanding of children's exposures to persistent pollutants,  to gain information on the various
activities,  environmental media,  and pollutant characteristics that may  influence children's
exposures,  and to generate further questions and hypotheses for future research.
II      Daycare Center Sample Subjects Recruitment

Detailed subjects recruitment procedures and sample selection methods are documented in CTEPP
SOP 1.10 and SOP1.11.  NC subjects recruitment was conducted in two phases. Phase I daycare
center subj ects recruitment in four NC counties (Durham, Buncombe, Lee, and Mecklenburg) began
in February 2000 and stopped on February 29, 2000 due to the OMB Y2K Census requirement.
Subjects recruitment resumed  in July 2000 and continued through December 2000.  Phase I
recruitment achieved 80% of the target subjects recruitment (enrolled 51 of 64 target subjects).

Phase II recruitment was conducted for the two eastern NC counties affected by the flooding that
resulted from Hurricane Floyd (Edgecombe and Jones). Phase II recruitment began on February
26,2001 and was completed on March 30,2001. Twelve additional subjects were enrolled in phase
II.  The project has achieved 98% of the NC daycare center subject recruitment target (enrolled 63
of 64 target subjects).
III.    Telephone Sample Subjects Recruitment

The sample design utilized for the CTEPP telephone component is intended to fulfill the objectives
of:

   •   Efficiently identifying telephone households having one or more children in the eligible age
       range and meeting the sampling targets in the high and low income domains

   •   Providing coverage of households with unlisted telephone numbers

With respect to the first obj ective, the Marketing Systems Group (MSG) uses Census data, marketing
research data,  and other sources to classify directory-listed households as having one or more
children in the age range of one to five years or no children in that age group. The same data is used
to assign the directory-listed households to an income range. While not all households classified as

-------
                                                         CTEPP Recruitment Report - North Carolina
                                                                                   Page 2


having children in the target age range will indeed have eligible children, the eligibility rate will still
be much higher than a simple random sample of households.

The counts of directory-listed households having children in the target age group for the counties
provided by MSG are considerably less than the Census demographic estimates. A portion of the
eligible households in a study county will be in the group of households that MSG has classified as
having no children in the target age range, but the eligibility rate will  still be very small. We  must
allocate some percentage of our sample to this group of directory-listed households. To allocate a
greater proportion of our total sample to the first group of households we stratified the directory-
listed households.

All directory-listed households in each of the six study counties were assigned to one of the 4 strata:

       1.  Directory-listed households with income above $25,000 and having one or more children
          in the target age range

       2.  Directory-listed households with income below or equal to $25,000  and having one or
          more children in the target age range

       3.  Directory-listed households with income above $25,000 and having no children in the
          target age range

       4.  Directory-listed households  with  income below  or equal to $25,000  and  having  no
          children in the target age range

With respect to the second objective, some counties may have as many as 30% of households with
unlisted telephone numbers, therefore some of the eligible households in a study county will  have
unlisted telephone numbers.  Trying to estimate the eligibility rate for households having unlisted
telephone numbers is difficult. We use a random digit dialing (RDD) approach to give these unlisted
telephone households some chance  of selection.

To implement the RDD approach, MSG first identifies all telephone exchanges in the study county.
Telephone exchanges having very low percentages of directory-listed households in the study county
are deleted. From the remaining exchanges, MSG draws a systematic sample of telephone numbers.
Some of these telephone numbers are residential and some are business and nonworking. To prevent
a directory-listed telephone number from being  sampled in both the RDD frame and the directory-
listed frame, MSG selects the RDD sample  of telephone numbers first. The sampled telephone
numbers are matched to the database  of directory-listed telephone numbers. Those telephone numbers
identified as directory-listed  are removed from the directory-listed frame prior to the stratification
described above.

Trying to determine the percentage of the total  sample that should be allocated  to the RDD frame
based is difficult. First, the proportion of working residential telephones can vary considerably  from
county to county  so trying to estimate the total number of telephone households in this frame is
imprecise. Second, the estimation of the eligibility rate in this frame is imprecise. Since the contact

                                                         CTEPP Recruitment Report - North Carolina
                                                                                   Page3

rate in this frame is substantially lower than any of the four directory-listed strata, the primary
determinant of our allocation is dialing efficiency.

Telephone subjects recruitment for four NC counties (Durham, Buncombe, Lee, and Mecklenburg)
began in July 2000 and completed in November 2000. The proj ect achieved 54% response rate (using
the response rate calculation method suggested by EPA) in Phase I recruitment and screened a total
of 244 potentially eligible households for the project. As of the end of December 2000, the  project
completed field sampling activities with 75% of the target participants (enrolled 48 of 64 target
subjects). Phase II telephone subjects recruitment for the two eastern NC counties (Edgecombe and
Jones) began in January 2001.  A total of 28  potentially eligible  subjects were identified. The
telephone subjects recruitment was completed on March 30,2001; a total of 67 subjects participated
in the study, which is 105% of the recruitment target.
IV     Summary

Table 1 provides detailed outcomes for telephone subjects recruitment.  A total of 12,262 phone
numbers were called. The project achieved 58% response rate. The method for calculating response
rates is also described in Table 1. Recruitment results for daycare centers and daycare parents are
provided in Tables 2 and 3. We used the same method suggested by EPA to calculate the response
rates. The project achieved 53% response rate for daycare centers and 50% response rate for daycare
parents.  The field  sampling activities were conducted in 23 weeks (Table 4).  The number of
participants in each county is summarized in Table 5. The participant's income status is summarized
in Table 6. The distribution of low and mid-to-high income among telephone (RDD) subjects is very
close to the original sampling plan. However, for daycare center subjects, low income subjects were
over enrolled, which was due to many of the subjects from the regular daycare centers being low
income subjects.

The  distribution of participants by NC counties is illustrated in Figure 1.  Figure 2  shows the
distribution of daycare center participants by urban and rural locations.  Figure 3  shows the
distribution of telephone (RDD) subjects by urban and rural locations.   Figure 4  shows the
distribution of daycare center participants by counties.  Figure 5 shows the distribution of RDD
telephone participants by counties.

I.      Introduction

The research study, "Children's Total Exposure to PersistentPesticides and Other Persistent Organic
Pollutants," (CTEPP) is a pilot-scale project involving about 260 children, which investigates the
possible exposures that  young children may have to common contaminants in their everyday
surroundings. These contaminants include several pesticides, phenols, polychlorinated biphenyls,
polycyclic aromatic hydrocarbons, some of which are suspected of being endocrine disrupters. The
targeted compounds are persistent in the indoor and sometimes the outdoor environments, so that
very low levels may exist in the children's surrounding microenvironments and provide a source of
chronic, non-acute exposure.   The primary purposes  of the research are to  increase  our
understanding of children's exposures to persistent pollutants, to gain information on the various
activities,  environmental  media,  and pollutant  characteristics that may influence children's
exposures,  and to generate further questions and hypotheses for future research.
II.     Daycare Center Sample Subjects Recruitment

Detailed subjects recruitment procedures and sample selection methods are documented in CTEPP
SOP 1.10 and SOP1.11.  Ohio daycare subjects recruitment began in January 2001 and completed
in November 2001. The project enrolled 16 child care centers (12 regular daycare and 4 Head Start),
completed sampling activities with 58 households, and achieved 91% of the planned target (64). The
daycare center response rate is 58% and the daycare parents response rate is 31% (using the response
rate calculation method suggested by EPA).
III.    Telephone Sample Subjects Recruitment

The sample design utilized for the CTEPP telephone component is intended to fulfill the objectives
of:

   •   Efficiently identifying telephone households having one or more children in the eligible age
       range and meeting the sampling targets in the high and low income domains

   •   Providing coverage of households with unlisted telephone numbers

With respect to the first obj ective, the Marketing Systems Group (MSG) uses Census data, marketing
research data,  and other sources to classify  directory-listed households as having one or more
children in the age range of one to five years or no children in that age group. The same data is used
to assign the directory-listed households to an income range. While not all households classified as
having children in the target age range will indeed have eligible children, the eligibility rate will still
be much higher than a simple random sample of households.

-------
                                                               CTEPP Recruitment Report - Ohio
                                                                                   Page 2
The counts of directory-listed households having children in the target age group for the counties
provided by MSG are considerably less than the Census demographic estimates. A portion of the
eligible households in a study county will be in the group of households that MSG has classified as
having no children in the target age range, but the eligibility rate will still be very small. We must
allocate some percentage of our sample to this group of directory-listed households. To allocate a
greater proportion of our total sample to the first group of households we stratified the directory-
listed households.

 All directory-listed households in each of the six OH study counties were assigned to one of the 4
strata:

       1.  Directory-listed households with income above $25,000 and having one or more children
          in the target age range

       2.  Directory-listed households with income below or equal to $25,000 and having one or
          more children in the target age range

       3.  Directory-listed households with income above $25,000 and having no children in the
          target age range

       4.  Directory-listed households  with income below or equal to  $25,000  and having no
          children in the target age range

With respect to the second objective, some counties may have as many as 30% of households with
unlisted telephone numbers, therefore some of the eligible households in a study county will have
unlisted telephone numbers.  Trying to estimate the eligibility rate for households having unlisted
telephone numbers is difficult. We use a random digit dialing (RDD) approach to give these unlisted
telephone households some chance of selection.

To implement the RDD approach, MSG first identifies all telephone exchanges in the study county.
Telephone exchanges having very low percentages of directory-listed households in the study county
are deleted. From the remaining exchanges, MSG draws a systematic sample of telephone numbers.
Some of these telephone numbers  are residential and some are business and nonworking. To prevent
a directory-listed telephone number from being sampled in both the RDD frame and the directory-
listed frame, MSG selects the RDD sample of telephone  numbers first. The sampled telephone
numbers are matched to the database of directory-listed telephone numbers. Those telephone numbers
identified as directory-listed are removed from the directory-listed frame prior to the stratification
described above.

                                                                CTEPP Recruitment Report - Ohio
                                                                                    Page 3
Trying to determine the percentage of the total sample that should be allocated to the RDD frame
based is difficult. First, the proportion of working residential telephones can vary considerably from
county to county  so trying to estimate the total number of telephone households in this frame is
imprecise. Second, the estimation of the eligibility rate in this frame is imprecise. Since the contact
rate in this frame is substantially lower than any of the four directory-listed strata, the primary
determinant of our allocation is dialing efficiency.

Telephone subjects recruitment for OH counties began in March 2001 and completed in November
2001. The project achieved an overall 57% response rate (using the response rate calculation method
suggested by EPA) and screened a total of 165 potentially eligible households for the proj ect. A total
of 69 subjects participated in the study, which is 108% of the recruitment target (64).
IV     Summary

Table 1 provides detailed outcomes for telephone subjects recruitment. A total of 10,179 phone
numbers were called. The proj ect achieved an overall 57% response rate. The method for calculating
response rates is also described in Table 1. Recruitment results for daycare centers and daycare
parents are provided in Tables 2 and 3. We used the same method suggested by EPA to calculate the
response rates. The project achieved 57% response rate for daycare centers and 31% response rate
for  daycare parents.  The field sampling activities were conducted in 27 weeks (Table 4).  The
number of participants in each county is summarized in Table 5. The participant's income status is
summarized in Table 6.

The distribution of participants by  OH counties is illustrated in Figure 1. Figure 2 shows the
distribution of daycare  center participants by urban and  rural locations. Figure  3  shows  the
distribution of telephone (RDD)  subjects by urban  and rural  locations. Figure  4  shows  the
distribution of daycare center participants  by  counties.  Figure 5 shows the distribution of RDD
telephone participants by counties.

I.      Introduction

The  research  study, "Children's  Total  Exposure  to  Persistent  Pesticides and  Other
Persistent Organic Pollutants," (CTEPP) is a pilot-scale project involving about 260
children, which  investigates the possible exposures that young  children may have to
common contaminants in their everyday  surroundings.  These contaminants include
several pesticides, phenols, polychlorinated biphenyls, polycyclic aromatic hydrocarbons,
some of which are suspected of being endocrine disrupters. The targeted compounds are
persistent in the indoor and sometimes the outdoor environments,  so that very low levels
may exist in the children's surrounding microenvironments  and provide a source of
chronic, non-acute exposure.  The primary  purposes of the research are to increase our
understanding of children's exposures to persistent pollutants,  to gain information on the
various activities, environmental media, and pollutant characteristics that may  influence
children's exposures,   and  to generate further  questions and  hypotheses for  future
research. This document provides  a summary of the quality assurance (QA) and quality
control (QC) procedures conducted for the CTEPP project. In the  following sections, we
describe the study activities and the QA/QC procedures. The relevant standard  operating
procedures (SOPs) are listed in the Reference Section at the end of this document.

II.     CTEPP Study Activities

As illustrated in Exhibit 1 (CTEPP Study Activities Flow Chart), CTEPP study activities
are conducted in three phases: Pre-Data Collection,  Field Data Collection, and Post-Data
Collection. To ensure data quality, standard operating procedures (SOPs) were developed
and project team members were trained according to the SOPs. All project activities were
conducted by trained project staff members, who were divided into the following project
teams:  1) recruitment team (including RDD and field teams), 2) field support team,  and
3) field data collection team.

The recruitment team was responsible for recruiting daycare and RDD home participants.
It was  supported by a team of telephone  interviewers and some field staff members.
During the pre-data collection phase,  the following  key activities were conducted by the
recruitment team and field support team.

   a  Recruit/Train Participants, Present T-shirts, Pay $25, Remind Food Samples
       Collection
   a  Label Sample Containers
   a  Compile Field Notebooks
   a  Pack Van, Check items  on the  check lists

The field support team conducted  QA/QC checks before and  after the preparation of all
field supplies, sample  containers, and data forms.  They  ensured that  all the  materials
needed for the field data collection activities were complete and accurate.

-------
CTEPP NC Data Collection QA/QC Report                              02/17/2004
After the field support team completed the preparation work, the field data collection
team did a final check on all needed field supplies, sample containers, and data forms for
the scheduled  sampling appointments. After loading the van and completing the final
checks,  the  field data collection team drove to the  sampling site for the scheduled
sampling appointment with the  study  subject. The following key  activities were
conducted by the field data collection team during the field data collection phase.

    a Field Data Collection Activities
    a Record Sample/Data Condition on Sample/Data Check Lists
    a Put Samples in ZipLoc Bags
    a Put Samples in Freezers
    a Record problems/issues on Daily Check List
    a Leave Field Notebooks in the CTEPP Workroom

Once the field  data collection team returned to the Battelle office, the field support team
received the field samples and data from the field data collection team. The following key
activities were  conducted by the field support team during the post-data collection phase.

    a Update Sample/Data Check Lists in the CTEPP  Tracking System (TS)
    a Verify Sample Conditions
    a Check Field Notebooks (data forms)
    a File Field Notebooks in the participant folders
    a Ship Samples
    a Conduct Data Entry
    a Update Progress Reports
    a Update QC Reports

In the following Sections, we describe specific QA/QC  procedures relevant to the CTEPP
data forms and database preparation.

III.   CTEPP QA/QC Procedures for Preparing the Data Forms and Database

Battelle  is  always committed  to the production of  highest quality  data.  A key  to
accomplish this objective is to implement standardized QA/QC procedures. QA/QC is a
continuous process.  As illustrated in Exhibit 2 (CTEPP QA/QC Procedures for Preparing
Data Forms and Database), Battelle implemented a comprehensive QA/QC plan to ensure
data quality in all phases of the CTEPP project, from pre-data collection to post-data
collection phase.

A.    Pre-Data Collection Phase:

Developed and Tested Data Forms, CA TI Programs
During the pre-data collection phase, the following data forms were developed.

•   Recruitment Survey  (Form #1)
C:\MYDATA FILE\CTEPPFinalReport91604\CTEPP QA_QCReportNC.doc

-------
CTEPP NC Data Collection QA/QC Report                               02/17/2004


•  House/Building Characteristics Observation Survey - Home (Form #2)
•  House/Building Characteristics Observation Survey - Child Day Care Center (Form
   #3)
•  Pre-Monitoring Questionnaire - Parent (Form #4)
•  Pre-Monitoring Questionnaire - Child Day Care Center (Form #5)
•  Post-Monitoring Questionnaire - Parent (Form #6)
•  Post-Monitoring Questionnaire - Child Day Care Center (Form #7)
•  Child Activity Diary/Parent - Children Don't Attend Day Care (Form #8)
•  Child Activity Diary/Parent - Children Attend Day Care (Form #9)
•  Child Activity Diary - Day Care Teacher (Form #10)

All the data forms were tested by trained project staff for consistency and accuracy. In
addition, mock interviews and field  data  collection  simulations were  conducted to
evaluate the effectiveness of the data forms.  The data  forms were finally reviewed and
approved by 1KB and OMB. Form #1 (Recruitment Survey) was modified into computer-
assisted telephone interviewing programs (CATI) for  recruiting the RDD participants
(children who did not attend daycares). The CATI programs automatically performed QC
checks during data  entry, which included range checks, consistency checks,  and skip
pattern checks. Before the CATI programs  were approved for actual RDD recruitment
and data collection, it also went through rigid QA/QC checks for programming errors.
Exhibit 3 provides an example of the QA/QC test document.

Conducted Staff Training on Data Collection SOPs
To ensure the consistency and high quality of data collection,  a comprehensive training
plan  was implemented.  The recruitment  team  members  received  training in the
implementation of the recruitment SOPs before  subject recruitment activities began.
Standardized scripts and materials (e.g., CATI system  and Interviewer's Manual) were
developed. The Interviewer's Manual provided information on the background  and aims
of this study, the standard interviewing  procedures, confidentiality  requirements, and
question-by-question specifications for the  recruitment survey.  Interviewers  must be
certified for the study before they can  initiate any contact with the  study subjects.  In
order to be certified as a CATI interviewer for the study, an interviewer must pass the
following two tests:

       1.  CATI Operation Test:    The interviewer must demonstrate that he/she is
                                 familiar with the CATI instrument and the
                                 computer-working environment.
       2.  CATI Interview Test:    The interviewer must conduct at least two mock
                                 CATI interviews and receive a satisfactory
                                 evaluation from the CATI supervisor.

Training  for the  field data collection team  members included  a  five-day (40-hour)
training session and additional self-practice time  was  provided to the field staff. The
following is  a brief summary of the training topics.
C:\MYDATA FILE\CTEPPFinalReport91604\CTEPP QA_QCReportNC.doc

-------
CTEPP NC Data Collection QA/QC Report                                02/17/2004


       Day 1:        Training covered study background, recruitment SOPs,
                     confidentiality issues, informed consent procedures, and the
                     interviewing protocol.

       Day 2:        The field staff members were trained to administer all the data
                     collection forms.

       Day 3:        The training included field sampling procedures, i.e., the use of
                     field notebooks and the collection of air, food, urine, dermal hand
                     wipes, hard floor wipes, food preparation surface wipes, the
                     polyurethane foam (PUF) roller for dislodgeable residues, indoor
                     floor dust, and soil samples. Internal field audits and QC
                     procedures were also discussed.

       Days 4/5:      A mock field sampling exercise (with 2 volunteers) was conducted
                     during the last two days of training. The field team visited the
                     volunteer's  home and conduct actual  field sampling activities. The
                     field staff members were also certified during these two days (i.e.,
                     they were required to pass the tests set for the field sampling
                     procedures).

       Day 5:        Training in  packing and shipping procedures were given on the
                     final day. The training ended with a final review of all  SOPs.

Before field data collection began, the field  support team members also went through
training for data form tracking and processing procedures, coding procedures, and quality
control procedures.

Conducted Participant Orientation/Training
Due to the unique features of the  CTEPP study, some key information and samples were
collected by the study participants  themselves.  Keeping the participants involved  and
well informed was critical to the  success of the study. All participants  (i.e.,  parents  and
day care staff) were  trained (i.e., received project orientation)  prior to the scheduled
sampling  appointment (normally one week  before the actual  sampling).  During  the
orientation/training, our project staff went through the  SOPs for collecting samples of
food,  urine, and dermal hand wipes  and recording the Child  Activity Diary with the
participants.

B.     Data Collection Phase:

Conducted CATI Monitoring
As a standard procedure to ensure data quality, Battelle routinely verifies data collection
activities.  For  monitoring CATI interviews  (Form  #1 RDD), Battelle  employed  a
sophisticated computer  software  (i.e., PROXY) and a telephone monitoring system to
validate CATI interview data. With the monitoring system,  the CATI  supervisor could
actually "watch" and "listen" an  interview in progress.  A  standardized  monitoring
C:\MYDATA FILE\CTEPPFinalReport91604\CTEPP QA_QCReportNC.doc

-------
CTEPP NC Data Collection QA/QC Report                               02/17/2004


procedure  was developed and used  for CATI monitoring.  The  supervisor randomly
selected an interview for monitoring. The monitoring system transferred the interviewer's
computer screen and telephone conversation in real time to the supervisor's workstation.
The interviewer being monitored or the study respondent could not notice any difference
while the monitoring was in progress.  To ensure the participant's right, a statement about
the interview that might be monitored by a project supervisor for quality assurance was
read to the respondent before the interview began. The monitoring results were recorded
in a CATI Interview Monitoring Form (See Exhibit 4).

Conducted Staff Field Edit
All field data collection team  members were trained to  conduct  field edit for  all
completed  data forms.  During data collection, the field staff conducted field edits to
identify  missing  data  items or questionable information at the sampling  site.  Any
identified issues or problems were resolved at the sampling site  before the field data
collection team returned to  Battelle whenever the field conditions allowed.  A  Daily
Activity  Check List was developed to assist the field staff in conducting data collection
activities and field  edit.  The field edits ensured that  any data collection issues or
problems were resolved early at the sampling site with the study participant.

Conducted Internal Field Audits
According  to  CTEPP SOP 2.25, Battelle conducted  periodical internal  field audits to
ensure high quality of data collection. The  internal field audits were conducted by the
Field Team Leader and/or field auditors. The field data collection team was not notified
of the field audit  visit. The field audit schedule was  randomly selected by the field
auditor/Field Team Leader. During a field audit visit, the field auditor observed all field
sampling activities according to the SOPs.  The field auditor recorded any findings or
observations about the field staffs work that was not consistent with the SOPs. Before
the end of each field audit visit, the field auditor  discussed the findings or observations
with the  field staff. A field audit report was prepared by the field auditor after each field
audit to document the field audit visit.

Conducted External Field Audits
In addition to Battelle internal field audits, some external field audits were conducted by
EPA auditor and project officer. On September 12 and 13, 2000, EPA audited the North
Carolina data collection teams. On June 5,  2001, EPA project officer  conducted field
observation visit with the Ohio data  collection teams. There was  no finding in all the
external field audits and observation visits.

C.     Post-Data Collection Phase:

Applied Chain of Custody Procedures
In order to protect the  study samples and data forms, a standardized chain-of-custody
procedure was developed and implemented for the CTEPP  study (See  SOP 2.26). In
addition, Battelle  developed a sophisticated CTEPP  Tracking System to monitor the
status of data collection. As soon as the field team returned to the office, the field support
(receiving) team checked the samples/data  condition and  updated the data collection
C:\MYDATA FILE\CTEPPFinalReport91604\CTEPP QA_QCReportNC.doc

-------
CTEPP NC Data Collection QA/QC Report                               02/17/2004


status in the CTEPP Tracking System (See Exhibit 5). The following information was
recorded for each study participant.

          •   Sample/Data Description
          •   Sample Type
          •   Sample ID#
          •   Staff s Name Who Collected the Sample/Data
          •   Date of Collection
          •   Sample Condition
          •   Number of Floor Dust Sampling Areas
          •   Sample Explanation (if Sample Condition = Explain)
          •   Staff s Name Who Received the Sample/Data from the Field Team
          •   Date Received Sample/Data
          •   Time Received Sample/Data

If the samples/data need to be shipped to another location, the CTEPP Tracking System
automatically generates a Chain-of-Custody record for the staff to sign.

Receiving Team Conducted QC Checks
After checking and storing the environmental and biological samples, the receiving team
conducted QC checks on all the participant's data forms and study materials. A CTEPP
Participant Data QC Check List was developed to track the QC status of each data item
(See Exhibit 6). The staff carefully reviewed each data form for missing or questionable
data items. After the staff completed the QC review, she/he put her/his initial and date of
review on the back of the data form. Any pending issues  (e.g., missing materials or
information) identified through the QC review were recorded in the  Check Notes of the
CTEPP Participant Data QC Check List. The field support staff resolved each pending
issue by checking with the field data collection staffer contacting the participant.

Developed and Tested Data Entry Programs
After the data forms went through the QC  checks and received a "complete" status, the
form was ready for data entry. Battelle programming team developed a double data entry
program to allow two separate  data entry  teams to conduct data entry.  The data entry
program was  designed  to  perform additional QC checks during  data entry,  which
included range checks, consistency checks,  and skip pattern checks. Before the data entry
program was  used for actual data entry, it was fully tested by trained project staff. An
example of the testing document is illustrated in Exhibit 7 (CTEPP Data Entry Program
Test). Examples of data entry program screens are illustrated in Exhibits 8, 9, and 10.

Conducted Double-Data Entry
All data forms were entered twice and verified, using the CTEPP  Double Data Entry
Program.  Two data entry teams (Teams A and B) performed the data entry work and
entered the data into  two separate databases. All the data  entry team  members were
trained before they were allowed to conduct data entry work. Each staff was assigned to
only one data entry  team and was not allowed to switch team. This  ensured that a data
form was entered twice by 2 different people. As a standard procedure for entering the
C:\MYDATA FILE\CTEPPFinalReport91604\CTEPP QA_QCReportNC.doc

-------
CTEPP NC Data Collection QA/QC Report                               02/17/2004


open text fields, the data entry teams were instructed to entered participant's responses
verbatim.

Conducted Computer Program Checks for Data Entry Errors
A computer verification program was developed for checking the accuracy of the entered
data and every  record in  the two databases was  crosschecked.  An  example of the
crosschecks computer  reports is illustrated in Exhibit  11  (CTEPP Double Data Entry
Crosschecks). The crosscheck computer reports identified any discrepancies between the
two databases. The reports displayed the Participant ID (PID), variable (data field) name,
data value in each database (Base vs. Compare), the difference between the 2 databases
(numeric fields only), and % difference (if applicable).

Correct Data Entry Errors
For each data item detected by the computer program, the data entry staff verified the
information with the original  participant data form and made corrections as needed. The
crosscheck computer reports made it easy for the staff to identify data entry problems and
to verify the information. This program also kept a log of all changes  made, including
original data value, date/time of data change, and name  of the  staff who made the
changes.

Prepare Final Master Database
A final master database  for  each data form was  prepared after all QC  checks  were
completed  and data entry  discrepancies were corrected. Backup  data files were also
created to protect the CTEPP data. All CTEPP data files and document  are protected by
password. Only  authorized project staff members have access to the restricted project
folders.

Prepare and Verify Data Dictionary and Document
After the completion of master database preparation, the programming team prepared the
updated data  dictionary for each data form database. The project staff verified the data
dictionaries by comparing the hard copy manuals, the electronic files, and the  database
structures.

Final Data Verification Checks
After completing all the tasks described in the earlier sections, the project staff conducted
a final  QA/QC check by verifying randomly selected participant files. Data items in the
database  were checked against the data documentation manual (i.e., data variables in the
data dictionary) and the actual participant data in the original data form. The results of the
random checks showed 100% accuracy. The  data in the original participant data form
were correctly recorded in the CTEPP database, and the data variables were accurately
documented in the data dictionary.  Before Battelle delivered the database to EPA, the
data variables containing personal identifiers (i.e., names, street address, GPS, etc.) were
removed from the database to ensure participant confidentiality. The results of the final
data verification checks are  shown in the following Table.

IV.    CTEPP QA/QC Procedures for the Analytical Database

Analytical data were electronically imported into the database according to CTEPP SOP
4.12.  The analytical raw data (QUAN report) were generated from each instrument by a
qualified analyst (the first data reviewer). The QUAN report was then reviewed by the
TOL (the second data reviewer) for all the identified analytes.  The QUAN report was
then electronically transferred into a custom report and saved as a "crd" file.  The "crd"
file was then electronically parsed into an Excel spreadsheet template, pertinent data such
as sample extraction weight and quality assurance codes were added and saved as an
Excel file with an extension of ".xls" by the first data reviewer. The TOL reviewed all
the Excel files before importing into the analytical database. If any anomalous results
were observed in the data, every effort was made to identify any problems in the sample
collection, sample preparation,  and/or analysis, which could have contributed to the
anomaly. Data dictionaries and code sets for core analytical data, QA/QC data, and
ancillary data were developed for the analytical  database.  The completed Excel
spreadsheets were then electronically imported into the analytical database by the
database staff.

Database queries were developed to perform QA/QC  checks. The QA/QC checks
performed for the Ohio analytical database include (1) sample ID checks, (2) missing
data checks, (3) duplication data checks, (4) out-of-range checks, (5) upper- and lower-
concentrations checks, and (6) calculation checks.
C:\MYDATA FILE\CTEPPFinalReport91604\CTEPP QA_QCReportNC.doc

-------
CTEPP NC Data Collection QA/QC Report                               02/17/2004
Sample ID checks
The sample ID checks were performed to verify that all Sample IDs with reported data
were valid Sample IDs, i.e., they were logged in as received from the field. If invalid
sample IDs were detected, the database staff traced back to the original raw data,
including laboratory record books and GC/MS logbooks, to identify the transcription
error and to make the corrections accordingly. All corrections were documented in the
database importing logbook.

Missing data checks
The missing data checks were performed to verify that all Sample IDs received from the
field had a full set of analytical data reported.  Samples that were received but that did not
have a complete set of analytical data and/or ancillary data, other than for a stated reason
in the electronic CoC data, were identified, and one of the following correction actions
was taken (as appropriate): analytical data was found and imported into the database, or
samples were located, processed, analyzed, reviewed, and the analytical data was
imported into the database.  Samples that were lost or damaged during laboratory
processing were identified and imported into the QA  Action table with an explanation
regarding their disqualification.

Duplicate data checks
Duplicate data checks were performed to verify that the same analytical data was not
imported into the database twice for a given sample.  The database staff traced the sample
results back to the laboratory record books, the GC/MS sequence logs, and/or the QUAN
reports to confirm that duplicate data was the result of a double import, and not a QA/QC
re-analysis (e.g. duplicate sample or duplicate injection). Once the duplicate data was
identified as a double import, the set of results for the sample having the oldest sample
import date were eliminated from the analytical database. If the duplicate  data was
identified as a QA/QC re-analysis, the proper QCC code was added to the QC_Code data
field, and the data for the first duplicate (only) remained in the Core_Analytical_Results
table, and the data for the first and second  duplicates  were reported in the
QA_QC_Results table.

Out of range checks
Out-of-range checks were performed to verify that all data for data fields limited to a
codeset did not violate that codeset.  For data fields that were limited to a codeset of
values, queries were performed to identify data within those fields that did not belong to,
or "violated", the codeset. Once identified, the database staff traced the sample results
back to the laboratory record books to identify the transcription error.  The data in the
database was corrected, and that correction was documented.

Upper- and lower- concentration checks
Upper- and lower-level concentrations checks were performed on approximately 5% of
the results that were plus or minus three standard deviations from the mean.  Database
queries were performed to identify those calculated results (Resultl and Result2) greater
than or less than three standard deviations  from the domain mean. Five percent of these
C:\MYDATA FILE\CTEPPFinalReport91604\CTEPP QA_QCReportNC.doc

-------
CTEPP NC Data Collection QA/QC Report                                02/17/2004


data were reviewed again by the data reviewer. The data reviewer checked the QUAN
report, all the parameters used for the results calculation, and the result calculation itself
to make sure that identification and quantification were performed correctly.  If the data
reviewers detected any mis-identification and/or mis-quantification, corrections were
made accordingly. The TOL approved the corrected data and the database manager made
the changes in the database.  All activities were documented in the laboratory record
books and database importing logbook.

Several additional checks were performed to:

       (1) review the SRS and MSS recoveries data greater than 150% and less than
       50%;
       (2) review the %D data that are greater than 50%;
       (3) add more flag codes to explain these QC data from items 1 and 2;
       (4) review all nonzero method blanks and field method blanks; and

Calculation Checks
Calculation checks were performed in Excel spreadsheets for selected samples to verify
that the calculations performed on Excel spreadsheet agreed with the calculations
performed on the analytical database.  Hand calculations, using a calculator, were
performed on select data to verify the calculated data agreed with the database calculated
data.

For those data requiring calculation of results,  a random subset (approximately 5%) of the
raw data was calculated using an independent calculation source (Excel) for validation.
In addition, hand calculations were performed on random data for each sample matrix
using a calculator.

                                   December 8, 1999

  1.     Add the following interviewer instructions to this question:  May I speak to the
        parent or guardian of the children in this household (OR NAME OF
        RESPONDENT IF OBTAINED THE NAME FROM PREVIOUS CALL)?-fixed
        EB 12/99

  2.     Skip pattern for answer #1 goes to Q3.  However, this question is numbered as Q2 in CATI. I
        combined question 2 and 3 into 1 question and called it Q2_3. Since it is really the same question
        with a little different wording depending on whether the parent answered the phone or had to be
        called to the phone. CWL - is that ok or do you want 2 separate questions? [CWL: Please
        program as 2 separate questions]  Fixed EB 12/99

        I did the same thing with questions 4a & c and 4 b & d. [CWL: Please follow the hard copy]. -
        Fixed EB 12/99

        ** Add Contact Information in the first screen (Subject's Name, Address, ID#, Phone #.) or
        create a Sub Form for this information and revise the instruction in Exit 4 accordingly. - cwl
        Sub form created EB 12/99

  3.     According to the HC, answer #4 (Refused, No Information) should go to Exit #1. CATI does skip
        to Exit #1, however, the skip also includes Exit #4. This makes sense, I just want to confirm since
        the HC doesn't mention Exit 4 in the skip pattern for response #4. Since Exit 1 didn't have any
        instructions in the hard copy, I added what I thought were reasonable instructions. CWL - Let me
        know if this is ok as is, or if I need to make changes.

  4.     Exit #1 script contains the following information that doesn't appear on HC:  IF
        CORRECT NUMBER: Thank you very much.  Goodbye. PRESS CTL/S  AND
        CHOOSE NONRESPONSE. See above comments.

  5.     Currently, the only month an appointment can be set is December 1999.1 set that
        up for testing purposes. CWL will need to look at the survey definition and let me
        know what changes need  to be made. EB  12/99

CTEPP OH QA/QC Report                                             02/17/2004
QA/QC Summary Report for CTEPP Ohio Data Collection
I.      Introduction

The research study, "Children's Total Exposure to Persistent Pesticides and Other Persistent
Organic Pollutants" (CTEPP), is a pilot-scale project involving about 260 children, which
investigates the possible exposures that young children may have to common contaminants in
their everyday surroundings.  These contaminants include several pesticides, phenols,
poly chlorinated biphenyls, and poly cyclic aromatic hydrocarbons, some of which are suspected
of being endocrine disrupters. The targeted compounds are persistent in the indoor and
sometimes the outdoor environments, so that very low levels may exist in the children's
surrounding microenvironments and provide a source of chronic, non-acute exposure.  The
primary purposes of the research are to increase our understanding of children's exposures to
persistent pollutants, to gain information on the various activities, environmental media, and
pollutant characteristics that may influence children's exposures, and to generate further
questions and hypotheses for future research. This document provides a summary of the quality
assurance (QA) and quality control (QC) procedures conducted for the CTEPP project. In the
following sections, we describe the study activities and the QA/QC procedures. The relevant
standard operating procedures (SOPs) are listed in the Reference Section at the end of this
document.

II.     CTEPP Data Collection Activities

As illustrated in Exhibit 1  (CTEPP Study Activities Flow Chart), CTEPP data collection
activities are conducted in three phases: Pre-Data Collection, Field Data Collection, and Post-
Data Collection.  To ensure data quality, standard operating procedures (SOPs) were developed
and project team members were trained according to the SOPs. All project activities were
conducted by trained project staff members, who were divided into the following project teams:
1) recruitment team (including RDD and field teams), 2) field support team, and 3) field data
collection team.

The recruitment team was responsible for recruiting daycare and RDD home participants. It was
supported by a team of telephone interviewers and some field staff members.  During the pre-
data collection phase, the following key activities were conducted by the recruitment team and
field support team.

       •  Recruit/Train  Participants, Present  T-shirts,  Pay  $25, Remind  Food  Samples
          Collection
       •  Label Sample Containers
       •  Compile Field Notebooks
       •  Pack Van, Check items on the check lists

The field support team conducted QA/QC checks before and after the preparation of all field
supplies, sample containers, and data forms. They ensured that all the materials needed for the
field data collection activities were complete and accurate.

CTEPP OH QA/QC Report                                             02/17/2004
After the field support team completed the preparation work, the field data collection team did a
final check on all needed field supplies, sample containers, and data forms for the scheduled
sampling appointments. After loading the van and completing the final checks, the field data
collection team drove to the sampling site for the scheduled sampling appointment with the study
subject. The following key activities were conducted by the field data collection team during the
field data collection phase.

       •  Field Data Collection Activities
       •  Record Sample/Data Condition on Sample/Data Check Lists
       •  Put Samples in ZipLoc Bags
       •  Put Samples in Freezers
       •  Record problems/issues on Daily Check List
       •  Leave Field Notebooks in the CTEPP Workroom

Once the field data collection team returned to the Battelle office, the field support team received
the field samples and data from the field data collection team. The following key activities were
conducted by the field support team during the post-data collection phase.

       •  Update Sample/Data Check Lists in the CTEPP Tracking System (TS)
       •  Verify Sample Conditions
       •  Check Field Notebooks (data forms)
       •  File Field Notebooks in the participant folders
       •  Ship Samples
       •  Conduct Data Entry
       •  Update Progress Reports
       •  Update QC Check List

In the following Sections, we describe specific QA/QC procedures relevant to the CTEPP data
forms and database preparation.

III.    CTEPP QA/QC Procedures for Preparing the Questionnaire Data Forms and
       Questionnaire Database

Battelle is always committed to the production of highest quality data.  A key to accomplish this
objective is to implement standardized QA/QC procedures. QA/QC is a continuous process.  As
illustrated in Exhibit 2 (CTEPP QA/QC Procedures for Preparing Data Forms and Database),
Battelle implemented a comprehensive QA/QC plan to ensure data quality in all phases of the
CTEPP project, from pre-data collection to post-data collection phase.

A.     Pre-Data Collection Phase:

Developed and Tested Data Forms, CA TI Programs
During the pre-data collection phase, the following data forms were developed.

-------
CTEPP OH QA/QC Report                                             02/17/2004


       •   Recruitment Survey (Form #1)
       •   House/Building Characteristics Observation Survey - Home (Form #2)
       •   House/Building Characteristics Observation Survey - Child Daycare Center (Form
          #3)
       •   Pre-Monitoring Questionnaire - Parent (Form #4)
       •   Pre-Monitoring Questionnaire - Child Daycare Center (Form #5)
       •   Post-Monitoring Questionnaire - Parent (Form #6)
       •   Post-Monitoring Questionnaire - Child Daycare Center (Form #7)
       •   Child Activity Diary/Parent - Children Don't Attend Daycare (Form #8)
       •   Child Activity Diary/Parent - Children Attend Daycare (Form #9)
       •   Child Activity Diary - Daycare Teacher (Form #10)

All the data forms were tested by trained project staff for consistency and accuracy. In addition,
mock interviews and field data collection simulations were conducted to evaluate the
effectiveness of the data forms. The data forms were finally reviewed and approved by IRB and
OMB. Form #1  (Recruitment Survey) was modified into computer-assisted telephone
interviewing programs (CATI) for recruiting the ROD participants (children who did not attend
daycares). The CATI programs automatically performed QC checks during data entry, which
included range checks, consistency checks, and skip pattern checks. Before the CATI programs
were approved for actual ROD recruitment and data collection, it also went through rigid QA/QC
checks for programming errors. Exhibit 3 provides an example of the QA/QC test document.

Conducted Staff Training on Data Collection SOPs
To ensure the consistency and high quality of data collection, a comprehensive training plan was
implemented. The recruitment team members received training in the implementation of the
recruitment SOPs before subject recruitment activities began.  Standardized scripts and materials
(e.g., CATI system and Interviewer's Manual) were developed. The Interviewer's Manual
provided information on the background and aims of this study, the standard interviewing
procedures, confidentiality requirements, and question-by-question specifications for the
recruitment survey. Interviewers must be certified for the study before they can initiate any
contact with the study subjects. In order to be certified as a CATI interviewer for the study,  an
interviewer must pass the following two tests:

       1. CATI Operation Test:    The interviewer must demonstrate that  he/she is  familiar
                                 with the CATI  instrument and  the  computer-working
                                 environment.
       2. CATI Interview Test:     The interviewer must conduct  at least two mock CATI
                                 interviews and receive a satisfactory evaluation from the
                                 CATI supervisor.

Training for the field data collection team members included a five-day (40-hour) training
session and additional self-practice time was provided to the field staff.  The following is a brief
summary of the training topics.

-------
CTEPP OH QA/QC Report                                              02/17/2004


       Day 1:       Training covered study background, recruitment SOPs, confidentiality
                    issues, informed consent procedures, and the interviewing protocol.

       Day 2:       The field staff members were trained to administer all the data collection
                    forms.

       Day 3:       The training included field sampling procedures, i.e., the use of field
                    notebooks and the collection of air, food, urine, dermal hand wipes, hard
                    floor wipes, food preparation surface wipes, the polyurethane foam (PUF)
                    roller for dislodgeable residues, indoor floor dust,  and soil samples.
                    Internal field audits and QC procedures were also  discussed.

       Days 4/5:     A mock field sampling exercise (with 2 volunteers) was conducted during
                    the last two days of training. The field team visited the volunteer's home
                    and conduct actual field sampling activities. The field staff members were
                    also certified during these two days (i.e., they were required to pass the
                    tests set for the field sampling procedures).

       Day 5:       Training in packing and shipping procedures was given on the final day.
                    The training ended with a final review of all SOPs.

Before field data collection began, the field support team members also went through training for
data form tracking and processing procedures, coding procedures, and quality control
procedures.

Due to the unique features of the CTEPP study, some key information and  samples were
collected by the study participants themselves. Keeping the  participants  involved and well
informed was critical to the success of the study.  All participants (i.e., parents and daycare staff)
were trained (i.e., received project orientation) prior to the scheduled sampling appointment
(normally one week before the  actual sampling).  During the orientation/training, our project
staff went through the SOPs for collecting samples of food, urine, and dermal hand wipes and
recording the Child Activity Diary with the participants.

B.     Data Collection Phase:

Conducted CATI Monitoring
As a standard procedure to ensure data quality, Battelle routinely verifies data collection
activities. For monitoring CATI interviews (Form #1 RDD), Battelle employed sophisticated
computer software (i.e., PROXY) and a telephone monitoring system to validate CATI interview
data. With the monitoring system, the CATI supervisor could actually "watch" and "listen" to an
interview in progress. A standardized monitoring procedure was developed and used for CATI
monitoring. The supervisor randomly selected an interview  for monitoring. The monitoring
system transferred the interviewer's computer screen and telephone conversation in real time to
the  supervisor's workstation. The interviewer being monitored or the study respondent could not
notice any difference while the monitoring was in progress.  To ensure the  participant's  right, a

statement that the interview might be monitored by a project supervisor for quality assurance was
read to the respondent before the interview began. The monitoring results were recorded in a
CATI Interview Monitoring Form (See Exhibit 4).

Conducted Staff Field Edit
All field data collection team members were trained to conduct field edit for all completed data
forms. During data collection, the field staff conducted field edits to identify missing data items
or questionable information at the sampling site.  Any identified issues or problems were
resolved at the sampling site before the field data collection team returned to Battelle whenever
the field conditions allowed. A Daily Activity Check List was developed to assist the field staff
in conducting data collection activities and field edit.  The field edits ensured that any data
collection issues or problems were resolved early at the sampling site with the study participant.

Conducted Internal Field Audits
According to CTEPP SOP 2.25, Battelle conducted periodic internal field audits to ensure high
quality of data collection. The internal field audits were conducted by the Field Team Leader
and/or designated field auditors.  The field data collection team was not notified of the field audit
visit. The field audit schedule was randomly selected by the field auditor/Field Team Leader.
During a field audit visit, the field auditor observed all field sampling activities according to the
SOPs.  The field auditor recorded any findings or observations about the field staffs work that
was not consistent with the SOPs. Before the end of each field audit visit, the field auditor
discussed the findings or observations with the field staff. A field audit report was prepared by
the field auditor after each field audit to document the field audit visit.

Conducted External Field Audits
In addition to Battelle internal field audits, some external field audits were conducted by an EPA
auditor and project officer.  On September 12 and 13, 2000, EPA audited the North Carolina data
collection teams.  On June 5, 2001, an EPA project officer conducted a field observation visit
with the Ohio data collection teams.  There were no findings in all the external field audits and
observation visits.

C.     Post-Data  Collection Phase:

Applied Chain of Custody Procedures
In order to protect  the study samples and data forms, a standardized chain-of-custody procedure
was developed and implemented for the CTEPP study (See SOP 2.26).  In addition, Battelle
developed a sophisticated CTEPP Tracking System to monitor the status of data collection. As
soon as the field team returned to the office, the field support (receiving) team checked the
samples/data condition and updated the data collection status in the CTEPP Tracking System
(See Exhibit 5).  The following information was recorded for each study participant.

       •   Sample/Data Description
       •   Sample Type
       •   Sample ID#
       •   Staff s Name Who Collected the Sample/Data
       •  Date of Collection

-------
CTEPP OH QA/QC Report                                              02/17/2004


       •   Sample Condition
       •   Number of Floor Dust Sampling Areas
       •   Sample Explanation (if Sample Condition = Explain)
       •   Staff s Name Who Received the Sample/Data from the Field Team
       •   Date Received Sample/Data
       •   Time Received Sample/Data

If the  samples/data need to be shipped to another location,  the  CTEPP  Tracking  System
automatically generates a Chain-of-Custody record for the staff to sign.

Receiving Team Conducted QC Checks
After checking and storing the environmental and biological samples, the receiving team
conducted QC checks on all the participant's data forms  and study materials. A CTEPP
Participant Data QC Check List was developed to track the QC status of each data item (See
Exhibit 6). The staff carefully reviewed each data form for missing or questionable data items.
After the staff completed the QC review, she/he put her/his initial and date of review on the back
of the data form. Any pending issues (e.g., missing materials or information) identified through
the QC review were recorded in the Check Notes of the CTEPP Participant Data QC  Check List.
The field support staff resolved each pending issue by checking with the field data collection
staff or contacting the participant.

Developed and Tested Data Entry Programs
After the data forms went through the QC checks and received a "complete" status, the forms
were ready for data entry. The Battelle programming team developed a double data entry
program to allow two separate data entry teams to conduct data entry.  The data entry program
was designed to perform additional QC checks during data entry, which included range checks,
consistency checks, and skip pattern checks. Before the  data entry program was used for actual
data entry, it was fully tested by trained project staff.  An example of the testing document is
illustrated in Exhibit 7 (CTEPP Data Entry Program Test).  Examples of data entry program
screens are illustrated in Exhibits 8, 9, and 10.

Conducted Double-Data Entry
All data forms were entered twice and verified, using the CTEPP Double Data Entry  Program.
Two data entry teams (Teams A and B) performed the data entry work and entered the data into
two separate databases.  All the data entry team members were trained before they were allowed
to conduct data entry work. Each data form was entered twice by 2 different people.  As a
standard procedure for entering the open text fields, the data entry teams were instructed to enter
participant's responses verbatim. [Note: Some of the participant reported information contained
typos or spelling errors. Per EPA's instructions (2/7/02 conference call), we have corrected
those spelling errors.]

Conducted Computer Program Checks for Data Entry Errors
A computer verification program was developed for checking the accuracy of the entered data
and every record in the two databases was crosschecked. An example of the crosschecks
computer program is illustrated in Exhibit 11  (CTEPP Double Keying Crosschecks &

-------
CTEPP OH QA/QC Report                                              02/17/2004


Corrections). The crosscheck computer program identified any discrepancies between the two
databases and the results were displayed on screen.

Corrected Data Entry Errors
For each data item detected by the computer program, the data entry staff verified the
information with the original participant data form and made corrections as needed.  The
crosscheck computer program made it easy for the staff to identify data entry problems and to
verify the information. This program also kept a log of all changes made, including original and
new data, date/time of data changed, and name of the staff that made the changes.

Prepared Final Master Database
A final master database for each data form was prepared after all QC checks were completed and
data entry discrepancies were corrected. Backup data files were also created to protect the
CTEPP data. All CTEPP data files and document are  protected by password. Only  authorized
project staff members have access to the restricted project folders.

Prepared and Verified Data Dictionary and Document
After the completion of master database preparation, the programming team prepared the
updated data dictionary for each data form database.  The project staff verified the data
dictionaries by comparing the hard copy manuals, the  electronic files, and the database
structures.

Final Data Verification Checks
After completing all the tasks described in the earlier sections, the project staff conducted final
QA/QC checks by reviewing data frequency reports and verifying (about 10%) randomly
selected participant files.  Data items in the database were checked against the data
documentation manual (i.e., data variables in the data dictionary) and the actual participant data
in the original data form.  The results of the random checks showed 100% accuracy. The data in
the original participant data form were correctly recorded in the CTEPP database, and the data
variables were accurately documented in the data dictionary. Before Battelle delivered the
database to EPA, the data variables containing personal identifiers (i.e., names, street address,
GPS, etc.) were removed from the database or the information was modified to ensure participant
confidentiality. The results of the final data verification checks are shown in Table 1.  A list of
data variables removed or modified for ensuring participant confidentiality is included in Table
2.

                                      December 8, 1999

  1.      Add the following interviewer instructions to this question: May I speak to the parent or guardian
         of the children in this household (OR NAME OF RESPONDENT IF OBTAINED THE NAME
         FROM PREVIOUS CALL)?-fixed EB 12/99

  2.      Skip pattern for answer #1 goes to Q3. However, this question is numbered as Q2 in CATI. I
         combined question 2 and 3 into 1  question and called it Q2_3. Since it is really the same question
         with a little different wording depending on whether the parent answered the phone or had to be
         called to the phone. CWL - is that ok or do you want 2 separate questions? [CWL: Please
         program as 2 separate questions] Fixed EB 12/99
                        I did the same thing with questions 4a & c and 4 b & d. [CWL: Please follow
                        the hard copy]. -Fixed EB 12/99
                        ** Add Contact Information in the first screen (Subject's Name, Address,
                        ID#, Phone #.)  or create a Sub Form for this information and revise the
                        instruction in Exit 4 accordingly. - cwl Sub form created EB 12/99
  3.      According to the HC, answer #4 (Refused, No Information) should go to Exit #1. CATI does skip
         to Exit #1, however, the skip also  includes Exit #4.  This makes sense, I just want to confirm since
         the HC doesn't mention Exit 4 in  the skip pattern for response #4. Since Exit 1 didn't have any
         instructions in the hard copy, I added what I thought were reasonable instructions. CWL - Let me
         know if this is ok as is, or if I need to make changes.
  4.      Exit #1 script contains the following information that doesn't appear on HC: IF CORRECT
         NUMBER:  Thank you very much. Goodbye.  PRESS CTL/S AND CHOOSE NONRESPONSE.
         See above comments.

  5.      Currently, the only month an appointment can be set is December 1999.1 set that up for testing
         purposes. CWL will need to look  at the survey definition and let me know what changes need to be
         made. EB 12/99

IV.    CTEPP QA/QC Procedures for the Analytical Database

Analytical data were electronically imported into the database according to CTEPP SOP
4.12.  The analytical raw data (QUAN report) were generated from each instrument by a
qualified analyst (the first data reviewer). The QUAN report was then reviewed by the
TOL (the second data reviewer) for all the identified analytes.  The QUAN report was
then electronically transferred into a custom report and saved as a "crd" file.  The "crd"
file was then electronically parsed into an Excel spreadsheet template, pertinent data such
as sample extraction weight and quality assurance codes were added and saved as an
Excel file with an extension of ".xls" by the first data reviewer. The TOL reviewed all
the Excel files before importing into the analytical database. If any anomalous results
were observed in the data, every effort was made to identify any problems in the sample
collection, sample preparation,  and/or analysis, which could have contributed to the
anomaly. Data dictionaries and code sets for core analytical data, QA/QC data, and
ancillary data were developed for the analytical  database.  The completed Excel
spreadsheets were then electronically imported into the analytical database by the
database staff.

Database queries were developed to perform QA/QC  checks. The QA/QC checks
performed for the Ohio analytical database include (1) sample ID checks, (2) missing
data checks, (3) duplication data checks, (4) out-of-range checks, (5) upper- and lower-
concentrations checks, and (6) calculation checks.

Sample ID checks
The sample ID checks were performed to verify that all  Sample IDs with reported data
were valid Sample IDs, i.e., they were logged in as received from the field. If invalid
sample IDs were detected, the database staff traced back to the original raw data,
including laboratory record books and GC/MS logbooks, to identify the transcription
error and to make the corrections  accordingly.  All corrections were documented in the
database importing logbook.

Missing data checks
The missing data checks were performed to verify that all Sample IDs received from the
field had a full set of analytical  data reported.  Samples that were received but that did not
have a complete set of analytical data and/or ancillary data, other than for a stated reason
in the electronic CoC data, were identified, and one of the following correction actions
was taken (as appropriate): analytical data was found  and imported into the database, or
samples were located, processed,  analyzed, reviewed, and the analytical data was
imported into the  database.  Samples that were lost or damaged during laboratory
processing were identified and imported into the QA Action table with an explanation
regarding their disqualification.

Table 3  presents a summary of the number of samples collected and the number of
samples with  data reported.
                                                                              22

       b Samples collected include all the number of real field samples followed by the number of field blanks in
         parenthesis.  Samples collected and samples reported do not include samples generated and analyzed as
         laboratory QC samples.

       d Sample OAA19745 was lost during the laboratory extraction.
       e The number of urine samples reported is the number of both composited and non-composited samples.

Duplicate data checks
Duplicate data checks were performed to verify that the same analytical data was not
imported into the database twice for a given sample.  The database staff traced the sample
results back to the laboratory record books, the GC/MS sequence logs, and/or the QUAN
reports to confirm that duplicate data was the result of a double import, and not a QA/QC
re-analysis (e.g. duplicate sample or duplicate injection).  Once the duplicate  data was
identified as a double import, the set of results for the sample having the oldest sample
import date were eliminated from the analytical database.  If the duplicate data was
identified as a QA/QC  re-analysis, the proper QCC code was added to the QC_Code data
field, and the data for the first duplicate (only) remained in the Core_Analytical_Results
table, and the data for the first and second duplicates were reported in the
QA_QC_Results table.

Out of range checks
                                                                                    23

Out-of-range checks were performed to verify that all data for data fields limited to a
codeset did not violate that codeset. For data fields that were limited to a codeset of
values, queries were performed to identify data within those fields that did not belong to,
or "violated", the codeset.  Once identified, the database staff traced the sample results
back to the laboratory record books to identify the transcription error. The data in the
database was corrected, and that correction was documented.

Upper- and lower- concentration checks
Upper- and lower-level concentrations checks were performed on approximately 5% of
the results that were plus or minus three standard deviations from the mean.  Database
queries were performed to identify those calculated results (Resultl and Result2) greater
than or less than three standard deviations from the domain mean.  Five percent of these
data were reviewed again by the data reviewer.  The data reviewer checked the QUAN
report, all the parameters used for the results calculation, and the result calculation itself
to make sure that identification and quantification were performed correctly. If the data
reviewers detected any mis-identification and/or mis-quantification, corrections were
made accordingly.  The TOL approved the corrected data and the database manager made
the changes in the database.  All activities were documented in the laboratory record
books and database importing logbook.

Several additional checks were performed to:

       (1) review the SRS and MSS recoveries data greater than 150% and less than
       50%;
       (2) review the %D data that are greater than 50%;
       (3) add more flag codes to explain these QC  data from items 1 and 2;
       (4) review all nonzero method blanks and field method blanks; and

Calculation Checks
Calculation checks were performed in Excel spreadsheets for selected samples to verify
that the calculations performed on Excel spreadsheet agreed with the calculations
performed on the analytical database.   Hand calculations, using a calculator, were
performed on select data to verify the calculated data agreed with the database calculated
data.

For those data requiring calculation of results, a random subset (approximately 5%) of the
raw data was calculated using an independent calculation source (Excel) for validation.
In addition, hand calculations were  performed on random data for each sample matrix
using a calculator.
                                                                               24

-------
Algorithms for Estimating Daily Ingestion Rate of Dust and Soil in Children Participants

       Daily ingestion rates of dust and soil were obtained from information found in the EPA
Exposure Factors Handbook. For all participating adult caregivers, the ingestion rates used in the
calculation were Md=25 mg/day and Ms=50 mg/day. For participating children, ingestion rates
were assigned by placing the children into one of three groups (Groups A, B, or C) based upon
their potential for soil ingestion, and then again into one of these three groups based upon their
potential for dust ingestion.

For dust ingestion. the following algorithm was used to assign children to Groups A, B, or C:

1.      Responses were obtained from the following questions on Form 04 (parent pre-
       monitoring questionnaire):
             Question C5: How often did [the child] play with sand or dirt?
       -     Question C6: Which of the following have you seen your child eat: dirt, sand,
             snow
2.      Based on the responses to these two questions, each participating child was placed into
       Group A, B, or C with regard to dust ingestion if any of the following was satisfied:

       Group A: -  Response to C5 was "most of the time"
                -  Response to C5 was "sometimes,"  and response to C6 was "dirt," "soil,"
                    and/or "snow"
       Group B: -  Response to C5 was "sometimes,"  and response to C6 did not include
                    "dirt," "soil," or "snow"
                -  Response to C5 was "rarely  or almost never," and response to C6 was
                    "dirt," "soil," and/or "snow"
       Group C: -  Response to C5 was neither  "most of the time" or "sometimes," and
                    response to C6 did not include "dirt," "soil," or "snow"

For soil ingestion. the following algorithm was used to assign children to Groups A, B, or C:

1.      Responses were obtained from the following questions on Form 04 (parent pre-
       monitoring questionnaire):
       -     Question C12: Did your child use a pacifier in the past month?
             Question C13a: In the past month, did [your child] suck or chew his/her
             thumb/fingers?
             Question C13b: In the past month, did [your child] suck or chew his/her toe/foot?
       -     Question C16: Did [your child] ever put his/her mouth on the floor and lick the
             floor?
       -     Question C21: Is your child currently teething?
       -     Question C22: How often did  [your child] put toys in his/her  mouth?
       -     Question C23: Did [your child] put  any things other than toys or food in his/her
             mouth?
                                          G-2

-------
2.     Based on the responses to these questions, each participating child was placed into Group
      A, B, or C with regard to soil ingestion if any of the following was satisfied:

      Group A:  -   Response to either C12 or C21 was "yes"
                -   Responses to C12 and C21 were both "no," response to C22 was
                    "frequently," and at least one "yes" response was given among questions
                    C13a, C13b, C16, and C23
                -   Responses to C12 and C21 were both "no," response to C22 was
                    "sometimes," and at least three "yes" responses were given among
                    questions C13a, C13b, C16, and C23
      Group B:  -   Responses to C12 and C21 were both "no," response to C22 was
                    "sometimes," and either one or two "yes" responses were given among
                    questions C13a, C13b, C16, and C23
                -   Responses to C12 and C21 were both "no," response to C22 was
                    "frequently," and no "yes" responses were given among questions C13a,
                    C13b, C16, andC23
                -   Responses to C12 and C21 were both "no," response to C22 was not
                    "frequently" or "sometimes," and at least three "yes" responses were
                    given among questions C13a, C13b, C16, and C23
      Group C:  -   Responses to C12 and C21 were both "no," response to C22 was not
                    "frequently" or "sometimes," and no more than two "yes" responses were
                    given among questions C13a, C13b, C16, and C23
                -   Responses to C12 and C21 were both "no," response to C22 was
                    "sometimes," and no "yes" responses were given among questions C13a,
                    C13b, C16, andC23

Once a participating child was placed into either Groups A, B, and C for soil ingestion and for
dust ingestion, then for both dust and soil, the daily ingestion rates were assigned as follows:

•     Children in Group A: Daily ingestion rate =100 mg/day
•     Children in Group B: Daily ingestion rate = 50 mg/day
•     Children in Group C: Daily ingestion rate = 25 mg/day

a The percentages were calculated using results from individual samples. Multiple samples for the same person or room were considered as
individual samples. The MQL is assumed to equal two times the MDL except as specified in Section 9.2. Cells corresponding to pollutants
having at least 50% of samples above the MQL in the specified matrix are shaded in gray.
b In addition to the pollutants represented in this table, atrazine was measured in drinking water samples. Twenty-two percent of NC drinking
water samples had atrazine levels at or above the MQL.
0 A dash indicates that the pollutant was not measured in the specified matrix.

a The percentages were calculated using results from individual samples. Multiple samples for the same person or room were considered as
individual samples. The MQL is assumed to equal two times the MDL except as specified in Section 9.2.  Cells corresponding to pollutants
having at least 50% of samples above the MQL in the specified matrix are shaded in gray.
b In addition to the pollutants represented in this table, atrazine was measured in drinking water samples. Fifty-seven percent of OH drinking
water samples had atrazine levels at or above the MQL.
0 A dash indicates that the pollutant was not measured in the specified matrix.
d Low recovery (<10%) of IMP was observed in matrix spikes, and therefore, IMP was not quantifiable in urine samples.

* Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations. This result is labeled as "detected" if any measurement entering into the calculation was
detected. Thus, N specifies the number of locations having data entering into the summaries. Reported measures of 0 ng/mL in liquid food do
not enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.

* Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations.  This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries. Reported measures of 0 ng/mL in liquid food do
not enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations. This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries. Reported measures of 0 ng/mL in liquid food do
not enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.

* Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations. This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries. Reported measures of 0 ng/mL in liquid food do
not enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.

* Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations.  This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries.  Reported measures of 0 ng/mL in liquid food do
not enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.

detected.  Thus, N specifies the number of locations having data entering into the summaries. Reported measures of 0 ng/mL in liquid food do
not enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.

* Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations.  This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries.  Reported measures of 0 ng/mL in liquid food do
not enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.

* Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations. This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries. Reported measures of 0 ng/mL in liquid food do
not enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations.  This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries.  Reported measures of 0 ng/mL in liquid food do
not enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations. This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries.  Reported measures of 0 ng/mL in liquid food do
not enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations.  This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries.  Reported measures of 0 ng/mL in liquid food do
not enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations. This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries. Reported measures of 0 ng/mL in liquid food do not
enter into the descriptive statistics.  Means and standard deviations are not reported when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations. This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries. Reported measures of 0 ng/mL in liquid food do not
enter into the descriptive statistics.  Means and standard deviations are not reported when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations.  This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries. Reported measures of 0 ng/mL in liquid food do not
enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations. This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries. Reported measures of 0 ng/mL in liquid food do not
enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations.  This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries. Reported measures of 0 ng/mL in liquid food do not
enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations.  This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries.  Reported measures of 0 ng/mL in liquid food do not
enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations.  This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries. Reported measures of 0 ng/mL in liquid food do not
enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations. This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries.  Reported measures of 0 ng/mL in liquid food do not
enter into the descriptive statistics.  Means and standard deviations are not reported when the percentage of detected results is below 50%.

* Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations.  This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries. Reported measures of 0 ng/mL in liquid food do
not enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations. This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries. Reported measures of 0 ng/mL in liquid food do
not enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.

* Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations. This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries. Reported measures of 0 ng/mL in liquid food do
not enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.

* Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations.  This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries. Reported measures of 0 ng/mL in liquid food do
not enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.

not enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.

* Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations.  This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries.  Reported measures of 0 ng/mL in liquid food do
not enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.

* Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations. This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries. Reported measures of 0 ng/mL in liquid food do
not enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations.  This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries.  Reported measures of 0 ng/mL in liquid food do
not enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations. This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries.  Reported measures of 0 ng/mL in liquid food do
not enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations.  This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries.  Reported measures of 0 ng/mL in liquid food do
not enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.

detected.  Thus, N specifies the number of locations having data entering into the summaries. Reported measures of 0 ng/mL in liquid food do
not enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.
Note that IMP data for solid and liquid food samples are to be interpreted with caution due to recoveries being below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations. This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries.  Reported measures of 0 ng/mL in liquid food do not
enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations. This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries.  Reported measures of 0 ng/mL in liquid food do not
enter into the descriptive statistics.  Means and standard deviations are not reported when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations. This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries. Means and standard deviations are not reported
when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations. This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries. Means and standard deviations are not reported
when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations. This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries. Means and standard deviations are not reported
when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations. This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries. Means and standard deviations are not reported
when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by 10 for liquid food samples and by the square root of 2 for all
other samples. Multiple or replicate sample results at a given location have been log-transformed, averaged, and exponentiated back to regular
units prior to summarizing the data across locations. This result is labeled as "detected" if any measurement entering into the calculation was
detected.  Thus, N specifies the number of locations having data entering into the summaries.  Reported measures of 0 ng/mL in liquid food do not
enter into the descriptive statistics. Means and standard deviations are not reported when the percentage of detected results is below 50%.

(a) For a given analyte, the media listed in this table represent those media for which statistical analysis was performed (i.e.,
having at least 50% detected results).
(b) In the last four columns of this table, significance levels are specified only when the environment effect was significant at the
0.05 level (column 4 of this table). These significance levels in these last three rows are adjusted based upon Tukey's
studentized range approach to controlling the overall Type I error rate (i.e., incorrectly declaring at least one pair of
environments significantly  different).

* Implies statistical significance at the 0.05 level, but not at the 0.01 level.
** Implies statistical significance at the 0.01 level.

(a) For a given analyte, the media listed in this table represent those media for which statistical analysis was performed (i.e.,
having at least 50% detected results).  In columns 2 through 4 of this table, cells are blank when insufficient data are available
for the given pollutant and sample medium to allow the statistical test specified in the column heading to be performed.
(b) In the last four columns of this table, significance levels are specified only when the environment effect was significant at the
0.05 level (column 4 of this table).  These significance levels in these last three rows are adjusted based upon Tukey's
studentized range approach to controlling the overall Type I error rate (i.e., incorrectly declaring at least one pair of
environments significantly different).

* Implies statistical significance at the 0.05 level, but not at the 0.01 level.
** Implies statistical significance at the 0.01  level.

(a) For a given analyte, the media listed in this table represent those media for which statistical analysis was performed (i.e.,
having at least 50% detected results).
(b) In the last four columns of this table, significance levels are specified only when the environment effect was significant at the
0.05 level (column 4 of this table). These significance levels in these last three rows are adjusted based upon Tukey's
studentized range approach to controlling the overall Type I error rate (i.e., incorrectly declaring at least one pair of
environments significantly different).
* Implies statistical significance at the 0.05 level, but not at the 0.01 level.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected.  Thus, N specifies the number of subjects having
data entering into the summaries. Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries. Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries.  Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries.  Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries.  Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries.  Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries.  Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries.  Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected.  Thus, N specifies the number of subjects having
data entering into the summaries. Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries. Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries.  Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries. Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries. Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries. Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries.  Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries. Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries. Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected.  Thus, N specifies the number of subjects having
data entering into the summaries. Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries.  Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries.  Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries. Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries.  Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries. Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries. Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected.  Thus, N specifies the number of subjects having
data entering into the summaries. Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries. Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries.  Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries.  Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries.  Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries. Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries.  Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries.  Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries.  Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries.  Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected.  Thus, N specifies the number of subjects having
data entering into the summaries. Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries. Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries.  Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected.  Thus, N specifies the number of subjects having
data entering into the summaries. Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries. Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries. Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries. Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries. Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries. Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries. Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Estimates are labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries.  Means and standard deviations are not reported when the percentage of detected estimates is below 50%.
"Potential Absorbed Dose" was calculated as the Potential Exposure times 50% (the assumed absorption factor into the body), divided by the subject's
body weight.

a Not detected results are replaced by the method detection limit (MDL) divided by the square root of 2. Multiple sample results for a given
study subject have been log-transformed, averaged, and exponentiated back to regular units prior to summarizing the data within a stratum. This
result is labeled as "detected" if any measurement entering into the calculation was detected.  Thus, N specifies the number of subjects having
data entering into the summaries. Means and standard deviations are not reported when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by the square root of 2. Multiple sample results for a given
study subject have been log-transformed, averaged, and exponentiated back to regular units prior to summarizing the data within a stratum. This
result is labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries.  Means and standard deviations are not reported when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by the square root of 2. Multiple sample results for a given
study subject have been log-transformed, averaged, and exponentiated back to regular units prior to summarizing the data within a stratum.  This
result is labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries.  Means and standard deviations are not reported when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by the square root of 2.  Multiple sample results for a given
study subject have been log-transformed, averaged, and exponentiated back to regular units prior to summarizing the data within a stratum. This
result is labeled as "detected" if any measurement entering into the calculation was detected.  Thus, N specifies the number of subjects having
data entering into the summaries.  Means and standard deviations are not reported when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by the square root of 2. Multiple sample results for a given
study subject have been log-transformed, averaged, and exponentiated back to regular units prior to summarizing the data within a stratum. This
result is labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries.  Means and standard deviations are not reported when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by the square root of 2.  Multiple sample results for a given
study subject have been log-transformed, averaged, and exponentiated back to regular units prior to summarizing the data within a stratum. This
result is labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having

a Not detected results are replaced by the method detection limit (MDL) divided by the square root of 2. Multiple sample results for a given
study subject have been log-transformed, averaged, and exponentiated back to regular units prior to summarizing the data within a stratum. This
result is labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries.  Means and standard deviations are not reported when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by the square root of 2. Multiple sample results for a given
study subject have been log-transformed, averaged, and exponentiated back to regular units prior to summarizing the data within a stratum. This
result is labeled as "detected" if any measurement entering into the calculation was detected. Thus, N specifies the number of subjects having
data entering into the summaries.  Means and standard deviations are not reported when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by the square root of 2. Multiple sample results for a given
study subject have been log-transformed, averaged, and exponentiated back to regular units prior to summarizing the data within a stratum. This
result is labeled as "detected" if any measurement entering into the calculation was detected.  Thus, N specifies the number of subjects having
data entering into the summaries.  Means and standard deviations are not reported when the percentage of detected results is below 50%.

a Not detected results are replaced by the method detection limit (MDL) divided by the square root of 2. Multiple sample results for a given
study subject have been log-transformed, averaged, and exponentiated back to regular units prior to summarizing the data within a stratum. This
result is labeled as "detected" if any measurement entering into the calculation was detected.  Thus, N specifies the number of subjects having
data entering into the summaries.  Means and standard deviations are not reported when the percentage of detected results is below 50%.

a Results are not presented because, for each environmental sample type whose measurements were used to calculate the
potential exposure/absorbed dose, less than 45% of the measurements were detected.
b For each environmental sample type whose measurements were used to calculate the potential exposure/absorbed dose, less
than 45% of the measurements were detected. However, results are presented because this was one of the eight pollutants
mentioned at the end of Section 9.2.
c The largest detection percentage among the environmental sample types whose measurements were used to calculate the
potential exposure/absorbed dose was between 45 and 50%.

(a) Blank cells in this table indicate that insufficient data were available in this study to make the statistical comparison specified in
the column heading for the given pollutant and exposure route.
(b) Tests for statistical significance of the child-adult differences are one-sided tests to determine whether estimates for children are
significantly higher than for adults.
(c) Tests were not performed because, for each environmental sample type whose measurements were used to calculate the
potential exposure/absorbed dose, less than 45% of the measurements were detected.
(d) For each environmental sample type whose measurements were used to calculate the potential exposure/absorbed dose, less
than 45% of the measurements were detected.  However, tests were performed because this was one of the eight pollutants
mentioned at the end of Section 9.2.
(e) The largest detection percentage among the environmental sample types whose measurements were used to calculate the
potential exposure/absorbed dose was between 45 and 50%.

* Statistically significant at the 0.05 level, but not at the 0.01  level.
** Statistically significant at the 0.01 level.

(a) Blank cells in this table indicate that insufficient data were available in this study to make the statistical comparison specified in
the column heading for the given pollutant and exposure route.
(b) Tests for statistical significance of the child-adult differences are one-sided tests to determine whether estimates for children are
significantly higher than for adults.
(c) Tests were not performed because, for each environmental sample type whose measurements were used to calculate the
potential exposure/absorbed dose, less than 45% of the measurements were detected.
(d) For each environmental sample type whose measurements were used to calculate the potential exposure/absorbed dose, less
than 45% of the measurements were detected.  However, tests were performed because this was one of the eight pollutants
mentioned at the end of Section 9.2.
(e) The largest detection percentage among the environmental sample types whose measurements were used to calculate the
potential exposure/absorbed dose was between 45 and 50%.

* Statistically significant at the 0.05 level, but not at the 0.01  level.
** Statistically significant at the 0.01 level.

a Results are not presented because, for each environmental sample type whose measurements were used to calculate the
potential exposure/absorbed dose, less than 45% of the measurements were detected.
b For each environmental sample type whose measurements were used to calculate the potential exposure/absorbed dose, less
than 45% of the measurements were detected.  However, results are presented because this was one of the eight pollutants
mentioned at the end of Section 9.2.
c The largest detection percentage among the environmental sample types whose measurements were used to calculate the
potential exposure/absorbed dose was between 45 and 50%.

(a) Results are not presented because, for each environmental sample type whose measurements were used to calculate the
potential exposure/absorbed dose, less than 45% of the measurements were detected.
(b) For each environmental sample type whose measurements were used to calculate the potential exposure/absorbed dose, less
than 45% of the measurements were detected. However, results are presented because this was one of the eight pollutants
mentioned at the end of Section 9.2.
(c) The largest detection percentage among the environmental sample types whose measurements were used to calculate the
potential exposure/absorbed dose was between 45 and 50%.
