EXECUTIVE SUMMARY

The gastrointestinal absorption of arsenic from soil samples collected from residential properties
at the Vasquez Boulevard and 1-70 (VBI70) Superfund site was measured using young swine.
Test materials include composite soil samples from five different residences with arsenic levels
ranging from 290 to 860 ppm. In addition, one sample was prepared by mixing clean site soil
(arsenic <10 ppm) with an arsenical herbicide (PAX) to yield a concentration of about 460 ppm.
Groups of animals (four animals per dose group) were given oral doses of reference material
(sodium arsenate) or test material twice a day for 12 days. Urine excreted by each animal was
collected on days 6-7, 8-9 and 10-11. The urinary excretion fraction (UEF) (the ratio of the
amount excreted per 48 hours divided by the dose given per 48 hours) was calculated for each
test material using linear regression analysis. The relative bioavailability (RBA) of arsenic in
test material compared to that in sodium arsenate (abbreviated NaAs) was calculated as:

the 95% UCL of the site-wide mean RBA value is recommended for use in calculation of human
risk from ingestion of arsenic in site soils. The results are shown below:

RELATIVE BIOAVAILABILITY OF ARSENIC IN VBI70 SITE SOILS

1.0 INTRODUCTION

Accurate assessment of the health risks resulting from oral exposure to any chemical frequently
requires knowledge of the amount of the chemical absorbed from the gastrointestinal tract into
the body. This information on absorption may be described either in absolute or relative terms:

Absolute Bioavailability (ABA) is the ratio of the amount of chemical absorbed
compared to the amount of chemical ingested:

Absorbed Dose

ABA =	

Ingested Dose

This ratio is also referred to as the oral absorption fraction (AF0).

Relative Bioavailability (RBA) is the ratio of the absolute bioavailability of some test
material compared to the absolute bioavailability of some appropriate reference
material, usually the chemical dissolved in water or some fully soluble form that
completely dissolves when ingested:

ABA (test material)

RBA	V	7

ABA (reference material)

For example, if 100 ug of arsenic dissolved in drinking water were ingested and a total of 90 ug
entered the body, the ABA would be 0.90 (90%). Likewise, if 100 ug of arsenic contained in
soil were ingested and 30 ug entered the body, the ABA for soil would be 0.30 (30%). If the
arsenic dissolved in water were used as the reference substance for describing the relative
amount of arsenic absorbed from soil, the RBA would be 0.30/0.90 = 0.33 (33%).

Using Bioavailability Data to Improve Risk Calculations for Arsenic

When reliable data are available on the bioavailability of arsenic in soil, dust or other soil-like
waste material at a site, this information can be used to improve the accuracy of exposure and
risk calculations at that site. Because the reference dose (RfD) and the slope factor (SF) for
arsenic are both expressed in terms of dose of soluble arsenic ingested in water, the adjustment
is most conveniently achieved by using the bioavailability data to modify the toxicity values to
account for differences in absorption between arsenic ingested in water and the absorption of
arsenic from site media. This is done as follows:

A BA {water)

RfDiadjusted) = RfD(IRIS) ¦	V 7

ABA(site medium)

VBI70 Arsenic RBA Final.doc

1


-------
ABAisite medium)

SF{adjusted) = SF(IRIS) ¦		——			

ABA(water)

If an RBA value is available that is based on a reference form of arsenic that is as well
absorbed as arsenic in water, then the adjustments may be made as follows:

RfD (IRIS)

RfD(adjusted) =		

SF (adjusted) = SF (IRIS) ¦ RBA

Alternatively, it is also acceptable to adjust the dose (rather than the toxicity factors) as follows:

Dose(adjusted) = Dose(default) ¦ RBA

This adjustment in dose is mathematically equivalent to adjusting the toxicity factors as
described above.

Purpose of this Study

Investigations performed at the Vasquez Boulevard and 1-70 (VBI70) Superfund site in Denver,
Colorado, have revealed that some residential properties have yard soil that is contaminated
with elevated levels of arsenic. This study was performed in order to obtain site-specific data
on the relative bioavailability of arsenic in yard soils in order to help improve the accuracy of
risk calculations for residents who may be exposed to arsenic in soil.

2.0 STUDY DESIGN

This investigation of arsenic absorption and excretion was performed in two sequential studies.
The basic design for each of these two studies is presented in Table 2-1. As shown, each study
investigated arsenic absorption from sodium arsenate (the reference material) and from three site-
specific soils, each administered to groups of animals at two different dose levels for 12 days. All
doses were administered orally.

2.1 Test Materials

Sample Selection

Test Materials 1 to 5 were samples of residential yard soil that were collected during Phase 3 or
the risk-based sampling activities at the VBI70 site. Samples were selected to cover a range of
arsenic concentrations in soil, and were also selected to provide reasonable spatial
representativeness across the site, including samples from the Swansea/Elyria, Cole and
Clayton neighborhoods. Soils with arsenic concentrations less than 200-250 ppm were not
included because the mass of soil required for swine dosing was not available. Test Material 6
was prepared by mixing clean site soil (As <10 ppm) with sufficient PAX (an arsenical
herbicide that is considered to be a potential source material) to yield a concentration of
approximately 516 ppm arsenic.

Sample Preparation

In all cases, each Test Material was prepared by combining all soil samples that had been
collected from the selected property. For example, for properties that had been sampled during
the risk-based sampling program (Test Materials 1 and 2), over 100 subsamples of soil were
combined. For properties selected from the Phase 3 program (Test Materials 3-5), three
samples (each a composite of 10 subsamples) were combined.

All sub-samples from a property were composited using a stainless steel bowl and mixing
spoon. The composites were then air dried, homogenized, and sieved to < 250 //m. Soil for
Test Material 6 was also prepared by drying and sieving prior to the addition of the PAX.

Arsenic Concentration

After compositing, drying, mixing, and sieving, the concentration of arsenic was measured in
each Test Material by several techniques. An initial estimate was derived by x-ray
fluorescence (XRF), and these initial values were used to calculate the dose of each soil to
administer to the test animals. Subsequently, additional aliquots of each Test Material were re-
analyzed by XRF and also by inductively coupled plasma (ICP) spectroscopy and by neutron
activation analysis (NAA). The results from these analyses are presented in Table 2-2 and are
shown graphically in Figure 2-1. As seen, although there is reasonable agreement among the
different measurements, the initial set of XRF values (XRF-1) tended to be somewhat higher
than the second set of XRF values (XRF-2) and the ICP and NAA values. For this reason, all

-------
final calculations of administered dose were based on the mean of the XRF-2, ICP and NAA
values.

Sample Speciation

An aliquot of each test material was analyzed by electron microprobe in order to identify the
different mineral forms of arsenic that were present in the sample and to estimate
approximately how much of the total arsenic was present in each form. The detailed results are
presented in Appendix A, and the results are summarized below:

Inspection of these data reveals the following main observations:

•	Arsenic in most site soils consists mainly as arsenic trioxide (AS2O3) and lead arsenic
oxide (PbAsO).

•	Most arsenic (72% to 88%) occurs in particles that are smaller than 10 um in diameter.

•	Essentially all arsenic-bearing grains are "liberated" (i.e., they are not contained within
any other matrix).

It is important to note that these quantitative estimates of particle frequency and relative arsenic
mass are based on examination of a relatively small number of arsenic-bearing particles (N =
104 to 262) in each sample. Consequently, the quantitative values reported should not be
considered to be highly precise, and apparent differences between samples may be due to
random variation in the analysis rather than authentic differences in composition.

2.2	Experimental Animals

Young swine were selected for use in these studies because they are considered to be a good
physiological model for gastrointestinal absorption in children (Weis and LaVelle 1991). The
animals were Pig Improvement Corporation (PIC) genetically defined Line 26, and were
purchased from Chinn Farms, Clarence, MO. Animals used in study 1 were intact males, while
animals used for study 2 were castrated males.

The animals were housed in individual stainless steel cages. All animals were held for several
days prior to beginning exposure to test materials to allow them to adapt to their new
environment and to ensure that all of the animals were healthy. In order to help minimize
weight variations between animals and groups, three animals most different in body weight on
day -1 (either heavier or lighter) were also excluded. The remaining animals were assigned to
dose groups at random. When exposure began (day zero), the animals were about 5-6 weeks
old and weighed an average of about 8.9 kg (Study 1) or 7.0 kg (Study 2). Animals were
weighed every three days during the course of each study. On average, animals gained about
0.4 to 0.5 kg/day, and the rate of weight gain was comparable in all groups. These body weight
data are summarized in Figure 2-2.

2.3	Diet

Each day every animal was given an amount of standard swine chow (University Feed Mill S II
(2) starter ration without added antibiotics) equal to 5% of the mean body weight of all animals
on study. Feed was administered in two equal portions (2.5% of the mean body weight) at 11:00
AM and 5:00 PM daily. Drinking water was provided ad libitum via self-activated watering
nozzles within each cage.

Periodic analysis of four water and two feed samples during this program yielded the following:

Water (ug/L)

Diet (ug/g)

0.23

0.15

Based on these data, estimated intake of arsenic in unexposed animals is less than 0.1 ug/kg-day
via water and about 10 ug/kg-day via the diet.

2.4 Dosing

Animals were exposed to sodium arsenate (abbreviated in this report as "NaAs") or test material
(site soil) for 12 days, with the dose for each day being administered in two equal portions
given at 9:00 AM and 3:00 PM (two hours before feeding). Dose material was placed in the
center of a small portion (about 5 grams) of moistened feed (this is referred to as a doughball"),
and this was administered to the animals by hand.

VBI70 Arsenic RBA Final.doc

-------
The dose levels administered were based on the arsenic content of the test material, with target
doses of 50 and 125 ug/kg-day for NaAs and each test material. As noted previously (see
Section 2.1), original dose calculations were made using the initial XRF analysis of arsenic
concentrations in the test materials (see XRF-1 values in Table 2-2). Actual administered
arsenic doses were re-calculated using the mean of subsequent analyses of the samples by XRF,
ICP and NAA (see Table 2-2) and measured body weights. These actual administered doses
are presented in Appendix B (Study 1) and Appendix C (Study 2).

2.5	Collection and Preparation of Samples

Urine

Samples of urine were collected from each animal for three consecutive 48-hour periods, on
days 6/7, 8/9 and 10/11. Collection began at 9AM and ended 48 hours later. The urine was
collected in a stainless steel pan placed beneath each cage, which drained into a plastic storage
bottle. Each collection pan was fitted with a nylon screen to minimize contamination with
feces, spilled food or other debris. Plastic diverters were used to minimize urine dilution with
drinking water spilled by the animals from the watering nozzle into the collection pan, although
this was not always effective in preventing dilution of the urine with water. Due to the length
of the collection period, collection containers were emptied at least twice daily into a separate
holding container. This ensured that there was no loss of sample due to overflow.

At the end of each collection period, the urine volume was measured and 60-mL portions were
removed for analysis. A separate 250-mL aliquot was retained as an archive sample. Each
sample was acidified by the addition of concentrated nitric acid. The samples were stored
refrigerated until arsenic analysis.

Feces

Feces were collected by placing a fine-mesh nylon screen beneath each cage. Samples were
transferred from the screen into a storage container twice per day, and the final sample
(collected over 48 hours) was weighed. Aliquots of 20-25 grams of feces were weighed and
freeze dried.

2.6	Arsenic Analysis

Urine

Urine samples were arranged in a random sequence and submitted to the laboratory for analysis
in a blind fashion.

Details of urine sample preparation and analysis are provided in the study project plan (EPA
1999). In brief, 25 mL samples of urine were digested by refluxing and then heating to dryness
in the presence of magnesium nitrate and concentrated nitric acid. Following magnesium
nitrate digestion, samples were transferred to a muffle furnace and ashed at 500°C. The
digested and ashed residue was dissolved in hydrochloric acid and analyzed by the hydride

-------
generation technique using a Perkin-Elmer 3100 atomic absorption spectrometer. Preliminary
tests of this method established that each of the different forms of arsenic which may occur in
urine, including trivalent inorganic arsenic (As+3), pentavalent inorganic arsenic (As+5),
mono-methyl arsenic (MMA) and di-methyl arsenic (DMA) are all recovered with high
efficiency.

A number of quality assurance steps were taken during this project to evaluate the accuracy of the
analytical procedures. Steps performed by the analytical laboratory included:

Spike Recovery

Randomly selected samples were spiked with known amounts of arsenic (usually 5-10 ug,
as sodium arsenate) and the recovery of the added arsenic was measured. Recovery for
individual samples typically ranged from 87% to 115%, with an average across all
analyses of 103 ± 5.2 % (N = 41).

Duplicate Analysis

Random samples were selected for duplicate analysis by the laboratory analyst. Duplicate
results typically had a relative percent difference (RPD) of 1-10%, with an average of 8.7
% (N = 81).

Standards

Samples of two different urine standards were run with each set of test samples. One
standard was a urine standard obtained from NIST (sample number 2670 Elevated) with a
nominal arsenic concentration of 480 ±100 ug/L. Results for this standard ranged from
530 to 560 ug/L, with a mean across all samples of 544.3 ± 9.6 ug/L (N = 7). The second
standard was an aqueous solution obtained from ERA (sample 9978) with a nominal
concentration of 92.9 ug/L. Results for this standard ranged from 92 to 102 ug/L, with a
mean across all samples of 96.2 ±1.7 ug/L (N =90).

Blanks

Blank samples run along with each batch of samples never yielded a measurable level of
arsenic, with all values being reported as less than 0.05 ug of arsenic.

In addition to these laboratory-sponsored QA procedures, an additional series of QA samples were
submitted to the laboratory in a blind fashion. This included a number of Performance Evaluation
(PE) samples (urines of known arsenic concentration) as well as a number of blind duplicates.

The results for the PE samples are shown in Figure 2-3. As seen, the PE samples included several
different concentrations each of several different types of arsenic (As+3, As+5, MMA and DMA,
both alone and in a mixture). In nearly all cases, there was good recovery of the arsenic in both
the first and the second study.

VBI70 Arsenic RBA Final.doc

7


-------
The results for blind duplicates are shown in Figure 2-4. As seen, there was good agreement
between results for the duplicate pairs in both the first and second study.

As a final check, a series of samples were submitted to a second laboratory for inter-laboratory
comparison of results. This included investigative samples (urines collected from study animals)
as well as several PE samples. The results are shown in Figure 2-5. As seen, there is generally
good agreement between the two laboratories.

Based on the results of all of the quality assurance samples and steps described above, it is
concluded that the analytical results for samples of urine are of high quality and are suitable for
derivation of reliable estimates of arsenic absorption from test materials.

Feces

After drying, 1.0 gram of fecal material was removed and digested with 10 mL of magnesium
nitrate and nitric acid using the same approach as described above for urine. Following
digestion, all sample preparation and analytical steps are the same as for urine.

3.0 DATA ANALYSIS

Figure 3-1 shows a conceptual model for the toxicokinetic fate of ingested arsenic. Key points
of this model are as follows:

•	In most animals (including humans), absorbed arsenic is excreted mainly in the
urine over the course of several days. Thus, the urinary excretion fraction (UEF),
defined as the amount excreted in the urine divided by the amount given, is usually
a reasonable approximation of the oral absorption fraction or ABA. However, this
ratio will underestimate total absorption, because some absorbed arsenic is excreted
in the feces via the bile, and some absorbed arsenic enters tissue compartments (e.g.,
skin, hair, etc.) from which it is cleared very slowly or not at all. Thus the urinary
excretion fraction should not be equated with the absolute absorption fraction.

•	The relative bioavailability (RBA) of two orally administered materials (e.g., test
material and reference material) can be calculated from the ratio of the urinary
excretion fraction of the two materials. This calculation is independent of the extent
of tissue binding and of biliary excretion:

AF0 {test) D ¦ AF0 {test) ¦ Ku UEF {test)

RBA(test vs ref) =	=	=	

^	J) AFa{ref) D ¦ AFa {ref) ¦ Ku UEF {ref)

Based on the conceptual model above, raw data from this study were reduced and analyzed as
follows:

•	The amount of arsenic excreted in urine by each animal over each collection period
was calculated by multiplying the urine volume by the urine concentration:

Excreted (ug/48hr) = Cone (ug/L) • Volume (L/48hr)

•	For each test material, the amount of arsenic excreted by each animal was plotted as
a function of the amount administered (ug/48 hours), and the best fit straight line
(calculated by linear regression) through the data (ug excreted per ug administered)
was used as the best estimate of the urinary excretion fraction (UEF).

•	The relative bioavailability of arsenic in test material was calculated as:

RBA = UEF(test) / UEF(NaAs)
where sodium arsenate (NaAs) is used as the frame of reference.

•	As noted above, each RBA value is calculated as the ratio of two slopes (UEFs),
each of which is estimated by linear regression through a set of data points.

Because of the variability in the data, there is uncertainty in the estimated slope

VBI70 Arsenic RBA Final.doc

9


-------
(UEF) for each material. This uncertainty in the slope is described by the standard
error of the mean (SEM) for the slope parameter. Given the best estimate and the
SEM for each slope, the uncertainty in the ratio may be estimated using Monte
Carlo simulation. The probability density function describing the confidence
around each slope (UEF) term was assumed to be characterized by a t-distribution
with n-2 degrees of freedom :

UEF {measured) - UEF(true)

SEM	tn~2

For convenience, this PDF is abbreviated T(slope, sem, n), where slope = best
estimate of the slope derived by linear regression, sem = standard deviation in the
best estimate of the slope, and n = number of data points upon which the regression
analysis was performed. Thus, the confidence distribution around each ratio was
simulated as:

T( slope, sem, ri)t
PDF(RBA)	' Jt

T(slope, sem, n)ref

Using this equation, a Monte Carlo simulation was run for each RBA calculation.
The 5th and 95th percentile values from the simulated distribution of RBA values
were then taken to be the 90% confidence interval for the RBA.

4.0 RESULTS

The doses of arsenic administered in this study are below a level that is expected to cause
toxicological responses in swine, and no clinical signs of arsenic-induced toxicity were noted in
any of the animals used in either Study 1 or Study 2.

4.1 Urinary Excretion Fractions

Detailed results from Study 1 and Study 2 are presented in Appendices B and C, respectively. The
results for urinary excretion of arsenic are summarized in Figures 4-1 to 4-8. Although there is
variability in the data, most dose-response curves are approximately linear, with the slope of the
best-fit straight line being equal to the best estimate of the urinary excretion fraction (UEF). This
finding is consistent with results from both animals and humans, which suggest that there is no
threshold for arsenic absorption or excretion up to doses of at least 5,000 ug/day (EPA 1995).

An exception to this pattern is observed for sodium arsenate in Study 1. As seen in Figure 4-1, the
dose-response curves on days 6-7 and days 8-9 are not well-described by a linear model. The
basis of this unexpected result appears to be the values derived for the low dose group. Indeed, the
amount of arsenic recovered in the urine of low-dose group animals on days 6-7 and 8-9 was more
than the nominal dose administered. Therefore, samples of the doughballs administered for the
time interval in question were analyzed in order to determine if the actual dose delivered to the
animals was that which was intended. The results are shown in Figure 4-9. As seen, it is clear that
an error occurred in the preparation of doughballs that were administered to Dose Group 2 on
study days 6-8. This in turn explains why the amount excreted in urine of animals from this group
was much higher than expected on days 6-7, and was somewhat higher than expected on days 8-9.
For this reason, the data points for animals in Dose Group 2 (the low dose of sodium arsenate) in
Study 1 on days 6-7 and 8-9 are judged to be erroneous and were excluded from the analysis.
Figure 4-10 shows the data set for sodium arsenate from Study 1 and Study 2 combined after
exclusion of these data points, along with the best fit regression line through the data.

The following table summarizes the best fit slopes (urinary excretion fractions) for sodium
arsenate and each of the test materials.

4.3 Fecal Excretion and Mass Balance

As shown in Figure 3-1, the amount of arsenic excreted in the feces is the sum of that which is
ingested but never absorbed, and that which is absorbed and then secreted in bile back into the
intestines. Assuming that biliary excretion of absorbed arsenic is a relatively minor metabolic
pathway, then the amount of arsenic excreted in the feces is expected to be high when the
urinary excretion fraction (and hence the RBA) is low.

Figure 4-11 plots the fecal excretion fraction (defined as the mass of arsenic excreted in feces
in 48 hours divided by the oral dose of arsenic administered in 48 hours) as a function of the
urinary excretion fraction. As seen, there is a clear negative trend, with low urinary excretion
being associated with high fecal excretion.

The sum of the two excretion fractions is equal to the total fraction of the administered dose
recovered in urine plus feces. These data are summarized below.

-------
As seen, the total fraction of the administered arsenic that was recovered in urine and feces
averaged about 70% (range = 53%-85%). This recovery is consistent with most other studies
of arsenic excretion in animals (USEPA 1995).

4.4 In Vitro Bioaccessability

Recently, an alternative approach for estimating the solubility (and hence the potential toxicity)
of arsenic in soils and other solid material has been developed. The details of the approach are
described in the project plan for this study (USEPA 1999). In brief, samples of soil are placed
in a test fluid designed to be similar to gastric fluid, and the fraction of the total amount of
arsenic in the sample which dissolves into the fluid under a specified set of conditions
(temperature, time, pH) is measured. This fraction of the total that is solubilized is referred to
as the in vitro bioaccessability (IVBA). IVBA results for the six test materials in this study are
summarized below:

TM4

TM5

TM5 (dup)

18.2

TM6

17.6

TM6 (dup)

19.6

Because of the many differences between the in vitro test system and the gastrointestinal tract
of a living organism (swine, human), it is not expected that the IVBA for a sample should be
equal to the ABA or the RBA for that sample. However, if solubility is a key determinant of
ABA and RBA, then it is expected that there should be a correlation between IVBA and RBA.
Figure 4-12 plots the measured IVBA values as a function of the measured RBA values. As
seen, there is a moderately good correlation between RBA and IVBA (R2 = 0.645), with a
slope of 0.8 and an intercept near zero. This indicates that, at this site, an in vitro measurement
of bioaccessability is a moderately good predictor of in vivo gastrointestinal absorption.

-------
5.0 DISCUSSION AND RECOMMENDATIONS

The RBA results for site soils collected from the VBI70 study area range from about 0.18 to 0.45,
with a mean of about 0.31. These values are all less than the default value of 0.8 recommended by
USEPA Region VIII, supporting the conclusion that arsenic in VBI70 site soils is not as well
absorbed as soluble arsenic. The detailed chemical mechanism accounting for this reduced
bioavailability of arsenic in site soils is not known, but almost certainly is related to the chemical
form of arsenic in the soils.

As shown in Appendix A and discussed in Section 2.1, all of the site soils evaluated in this
study are characterized by a mixture of arsenic trioxide and lead arsenic oxide particles, with
most of the particles being less than 10 um in diameter. Based on this general similarity in
composition and particle size distribution, it is concluded that the apparent variations in RBA
between different site samples is likely to be due mainly to random variations in bioassay
results, and that the best estimate of an RBA value for the site should be based on the combined
information from all five site soils (TM1 to TM5). Since TM6 is not an actual site sample, data
from TM6 were not included in the summary statistics. Because of the inherent variability and
uncertainty in the data, the 95% UCL of the mean is recommended as the most appropriate
statistic for use in assessing human health risk from arsenic in soil. Summary statistics for the
combined data are presented below:
