OBSERVATIONS ON OPERATIONS AND STUDY DESIGN
It is important, in studying exposure to point source and ubiquitous
chemicals, to carefully define each study site area and to the extent possible
conduct probability sampling relative to that population. A probability
samRle is needed to develop valid, unbiased estimates of exposure and body-bur-
den levels for a study population and its relevant subpopulations. Hypothesis
tests about differences in exposure levels, for example, also depend on a
. scientific sample. Even model development, if it is to pertain to the particu-
lar finite study population, must be based on a probability sample if it is to
stand against intense scrutiny. One of the most compelling arguments for
probability-based estimates is the ability to develop probability statements
relating to their precision.
A good question is this: If response rates are as low as they were for
several of the estimates at each study site, is it worthwhile to conduct
probability sampling? The distortion that might result from such response
rates depends on the differences between "respondents" and "nonrespondents."
Admittedly, the lower the response rate is, the weaker the conclusions are.
However, one should not adopt a method that is known! priori to be weak no
matter what the participation rate, especially when the additional cost of a
more sound methodology is so small relative to the overall study cost (the
difference in cost between conducting a probability survey and one that is
subjective is trivial compared to the total cost of data collection and quanti-
tation in such studies). Two conclusions are noteworthy in this study: (1)
the extent to which the study population has been measured is known (which
would not be known if purposive sampling was used); and (2) the method used to
account for nonresponse observations tended to reduce the nonresponse bias.
Also, suggestions are offered in Section 6 for further improvements on the
very important issue of response rates. Why is it an important issue? One
might contend that willingness to respond cannot be related to exposure or
body burden, but this cannot be ascertained.
Nonresponse of individuals in a probability sample causes biased esti-
mates if the nonresponse does result in a disproportionate loss of sample
units with respect to the attributes of interest. If, for example, blood
2
-------
levels are being estimated and proportionately more individuals with high
.. .
,levels refuse than do individuals with low levels, then the results will be
downward biased. The method used to adjust sampling weights in this investi-
gation was designed to offset such an imbalance, by adjusting within a segment.
The stratification used in this study did not produce consistent results
acrQSS all chemicals and media studied, which may be a result of incomplete
identification of point. sources. It is recommended that stratification be
used in future body-burden studies, but that point sources be more rigorously
defined and that the population sizes of all strata be relatively equal to
help reduce unequal weighting effects.
Hypergeometric sampling of individuals was used in Louisiana and North
Carolina, but not in Texas. The hypergeometric method appears to be useful
and plausible. This technique does require virtually full-time attention from
the survey operations supervisor and a carefully controlled method for issuing
field assignments. This is especially true when it is difficult to find
sufficient eligible people in the screened population, as was the case in
Geismar, LA.
Based on the experience gained during this study, the methodology developed
for the field aspects of this study was effective and is appropriate for
further use. Most aspects are satisfactory as they are currently formulated,
while a few need some modification to increase their utility. The initial
field activities followed standard RTI procedures for counting and listing of
sample segments and for screening specified housing units. These activities
were all completed successfully and can be used with further modifications
based not on methods, but based only on the substance of the future study.
The main study field data collection phase consisted of contacting selected
respondents, recruiting them into the study, administering the Study Questionn-
aire, establishing the appointment for sample collection, and supporting that
activity. All of these procedures, with one exception, operated in an appropr-
iate and adequate manner. The sole exception is the method used for identifying
sample members. Due to the sample selection scheme implemented by the statis-
ticians, replacement samples were released to the field staff one at a time.
This led to inefficiencies in field activities, with associated increases in
field costs in terms of interview salaries and expenses.
3
-------
In general, all of the procedures that were developed for use in this
study worked well and allowed for a generally efficient collection of both
data and the environmental and biological samples. This field methodology can
be used in other studies of this type with only minor modifications. The only
changes to be considered would be those related to the type of information
beiilg sought, as it impacts on the screening variables and the explanatory
variables used in designing the actual data collection instruments to be used.
An additional concern. in this type of study is the response rate of
individuals selected to be the sampled respondents. The natural reluctance of
people to participate in a study that includes invasive procedures, such as
blood and breath sampling, was added to a growing level of nonparticipation in
any study and resulted in lower-than-expected levels of participation. The
demonstration of positive benefit for participation, other than a cash incentive,
might increase the participation rate.
Response to the study should be examined
in all future plans.
Quality control data were examined to determine the precision and accuracy
of the analysis of environmental and body-burden samples and for assessing the
measurement air associated with the collection and analysis of samples from
the three study site areas. The results obtained from the laboratory and
field blank cannisters or cartridges associated with each of the sampling
devices indicated that no appreciable background contribution was observed or
significantly contributed to compromising the samples analyzed from the three
study site areas. Only a few of the halocarbons exhibited any trace levels of
contamination (chloroform, 1,1,1- trichloroethane, carbon tetrachloride, and
tetrachloroethylene). However, these low nanogram levels were subtracted from
the values obtained in the field samples.
The overall recovery of halocarbons for the three geographical areas
studied ranged from 68 to 145 percent with a coefficient of variation of 6 to
33 percent. For water, the overall recovery of halocarbons was 71 to 90
percent with a coefficient of variation (CV) of 2 to 34 percent, with the
exception of three chemicals (chlorotoluene, chloroform, and ~-dichlorobenzene
which were 47, 49, and 46 percent). The overall recovery of halocarbons from
blood field controls for the three study areas ranged from 62 to 103 percent
and the CV was 3 to 48 percent.
4
-------
A statistical analysis of the matching replicate samples that were
collected in the three areas was also performed to assess the measurement
error. This measurement error was for the overall process (i.e., for the
collection and analysis of duplicate samples) and not simply a replicate
instrumental analysis.
. First, the percent agreement between the replicate samples was computed
for duplicates for each of the halocarbons that provided a sufficient number
of sample values above the quantifiable limit for subsequent statistical
analysis. The data indicated that, in most cases, the agreement was greater
than 80 percent, i.e., when both replicate samples gave measurable or nonmeasur-
able values (below the limit of detection). For those cases where discrepancies
occurred between replicate samples (i.e., one sample yielding a measurable
value and the second sample yielding a nonmeasurable value), the largest
number of discrepancies occurred with l,l,l-trichloroethane and carbon tetra-
chloride in fixed air; chloroform, trichloroethylene, and bromodichloromethane
in breath; and carbon tetrachloride and tetrachloroethylene in water. In most
cases the disagreements were relatively minor: the percentages of large
disagreement across compounds were almost all less than 2 percent of all the
samples; for fixed-site air, these percentages were usually less than 5 percent.
Summary statistics for the coefficient of variation between replicate
pairs of samples were also computed. The median, minimum, and maximum CV by
compound and median for matched pairs of samples indicated that the overall
median CV was usually less than 50 percent. The average median over compounds
for each medium was:
water, 32%; breath,
33%; fixed-site
air,
51%; and
personal air, 27%.
For the three media of breath, fixed-site air, and personal
air, the median CV for chloroform and 1,2-dichloroethane was somewhat larger
than for the other compounds examined.
Pearson and Spearman correlations between replicate samples were computed
when both amounts were measurable, if there were more than. five measurable
pairs.
In general, the majority of the correlations were significant from 0
at the 0.05 level.

field sample data
Plots of a sample versus its duplicate results were also
to gain insight into the comparability of the replicate
over all sample areas. In general, the plots exhibited
considerable scatter about the 45° line; however, the majority of points were
5
-------
within !25 percent of this 45° theoretical line. The relationship for 1,1,1-
trichloroethane (which had a large dynamic range) showed the highest linear
trend of the compounds plotted. A comparison of the correlation coefficients
for the halocarbons in personal air and fixed-site air for sampling and analysis
of replicates revealed that similar magnitudes in variation were obtained.
The:plots, in general, demonstrated a good linear relationship when the dynamic
range of the data was relatively large (i.e., approximately three orders of
magnitude). However, when the range was small, the linear relationship was
not so apparent. Also, larger relative discrepancies occurred between replicate
samples when the magnitude of the data was near or below the quantifiable
limit.

r(all) = Spearman correlation coefficient for all values.
r(meas.) = Spearman correlation coefficient for measurable ~alues
only.
* = Correlation significantly different from zero at the
.05 level.
n = Sample size.
o = Measurable in both media.
x = Below quantifiable limit in at least one media.
The + indicates the maximum quantifiable limit (over areas) for each
media.
Data for all plots are on the loge scale (Note the scales on all graphs
start at zero because 1 was added to all values before logarithms were
taken) .
D=
Median of values on the vertifical axis for the intervals indi-
cated on the horizontal axis. On the horizontal scale the box
is plotted at the midpoint of the interval.
(2) = Two observations are at this point.

Not measured.
For computing statistics, values below the LOD (limit of detection)
were set equal to ~ the LOD. Values at trace were sei equal to 5/8
the Q.L. (quantifiable limit).
1/
Statistics in the table are population estimates (i.e., they are
weighted statistics) and the estimated population is for persons
aged 45-64 with no occupational exposure during the prior year and
who have resided in the study area for at least one year. Note,
that the summary statistics in east Baton Rouge/Geismar are
dominated by the "other" strata and in Southeast Harris County by
the "low" strata. See tables 1-7 for population sample sizes by
strata.
Weighted sample means, standard errors and medians are presented
only for compounds with >5% of values over the maximum quantifiable
limit.
