CONVENE MEETING AND IDENTIFICATION OF BOARD MEMBERS

Mr. Jim Downing (Designated Federal Officer [DFO], Human Studies Review
Board [HSRB or Board], Office of the Science Advisor [OSA], U.S.
Environmental Protection Agency [EPA or Agency]) opened the
teleconference meeting and welcomed Board members on behalf of the EPA
Science Advisor Dr. Paul Anastas and the Program in Human Research
Ethics. He noted that the Agency appreciates the Board members’ time
in preparing for the meeting. He also welcomed EPA colleagues and
members of the public. The purpose of this teleconference meeting was to
review the decisions made by the Board at the April 13-14, 2011, HSRB
meeting and to finalize the Board report from that meeting. In addition,
the Board considered a draft letter from an HSRB workgroup on providing
research participants with individualized study results measuring the
amount of antimicrobial cleaning products on participants’ skin and
the amount inhaled while mopping floors. 

Meeting Administrative Procedures

As DFO, Mr. Downing serves as the liaison between the HSRB and EPA and
ensures that Federal Advisory Committee Act (FACA) requirements are met
with regard to the operations of the HSRB. As DFO, he also works with
the appropriate officials to ensure that all applicable ethics
regulations are satisfied. Each Board member has been briefed on the
provisions of the federal conflict of interest laws and has filed a
standard government financial disclosure form that has been reviewed to
ensure that all ethics disclosure requirements have been met.
Mr. Downing reminded participants that meeting times listed on the
Agenda would be approximate, and that Board members should state their
names before speaking. At the appropriate time, members of the public
may provide public comments; these must be limited to 5 minutes.

Copies of the meeting materials are available on regulations.gov under
the docket number EPA-HQ-ORD-2011-0418. According to FACA requirements,
meeting minutes, including descriptions of the discussions and
conclusions reached by the Board will be prepared. These minutes will be
certified by the Chair within 90 days of the meeting and posted at
www.regulations.gov and on the HSRB Web site. 

Meeting Process

Dr. Sean Philpott explained that the Board would discuss the draft final
Board report, focusing on the charge questions presented to the Board at
the April 2011 meeting and summarizing the Board’s response. The
report is intended to be a summary of the HSRB’s consensus
recommendations and not a detailed document. The Agency and study
sponsors have access to detailed meeting minutes for additional
information.

Dr. Philpott noted that comments were received from seven HSRB members
and most of the changes have been incorporated into the draft final
Board report, resulting in a document version with pagination that may
differ from the pagination in the online draft final report. Dr.
Philpott requested all Board members to refer to paragraph introductions
within sections to facilitate information location during discussions. 

	For each charge question, Board members will have an opportunity to
raise concerns they may have about Board conclusions and rationales.
Dr. Philpott requested that the HSRB focus on substantive changes to
the report that directly affect the Board’s recommendations. Board
members should submit typographical and grammatical corrections to Dr.
Philpott and Mr. Downing via e-mail, and they will be incorporated into
the final report.

 

Public Comments

Dr. Philpott invited public comment on the draft April 2011 HSRB meeting
report. No public comments were presented. 

Board Discussion and Decision on Final Report

Assessment of Completed Agricultural Handler Exposure Task Force (AHETF)
Research Studies AHE62, AHE63 and AHE64: Determination of Dermal and
Inhalation Exposure to Workers During Airblast Applications of Liquid
Sprays Using Open-Cab Equipment (MRID 48289611, 48289612, 48289613,
48289614, 48289615, 48289616 and 48326701)

Dr. Philpott first addressed the AHETF study to determine exposure to
workers during airblast application of liquid sprays using open-cab
equipment. Dr. Philpott noted that the science charge to the Board had
asked whether the research reported in the completed AHETF study
monograph report and associated field study reports was faithful to the
design and objectives of the protocol, standard operating procedures
(SOPs) and governing documents. The Board concluded that the research
reported was conducted in a manner that was reasonably faithful to the
design and objectives of the protocol and governing documents of the
AHETF study. The Board also was asked to consider whether EPA had
adequately characterized, from a scientific perspective, the limitations
on these data that should be considered when using the data to estimate
exposure of those who apply pesticides with open-cab airblast equipment.
The HSRB concluded that the Agency has adequately, but not completely,
considered the limitations that should be considered when using these
data to estimate the dermal and inhalation exposure of those who apply
conventional pesticides with open-cab airblast equipment. The Board
members identified additional limitations and concerns, and suggested
that the ability to generalize these data requires further consideration
and analysis. 

Dr. Linda Young suggested that the Board examine the changes from Dr.
Dallas Johnson that have been incorporated into the draft Board report.
Under detailed recommendations and rationale, in the paragraph that
begins “The third limitation is the possible exceptional status of one
monitoring unit involved in exposure monitoring for open-cab spraying of
Oklahoma pecans…”, Dr. Michael Lebowitz noted that a change had been
suggested by Mr. Matthew Crowley (EPA, Office of Pesticide Programs
[OPP]), and Dr. Johnson had agreed with the change. The suggested
changes were to add “The Board concluded that…” to the sentence
“Increasing nozzle pressure will cause a decrease in droplet size and
an increase in spray drift”, and to change “will” to “would
likely.” Dr. Philpott confirmed that this change had been made, but
that no reference was provided. Dr. William Popendorf noted that there
are references that could be provided based on research going back to
the 1970s; since the statement seemed to be broadly general knowledge,
he did not require a reference to be entered. Dr. Young expressed
concern that the suggested change indicates that the science is not as
strong as it is. Dr. Popendorf noted that the previous version of the
sentence had read “The Board recognized that increasing nozzle
pressure will cause a decrease in droplet size and an increase in spray
drift.” The Board members supported a change back to this language.
Mr. Jeff Dawson (EPA, OPP) suggested that the line end with “an
increase in the potential for spray drift” because other factors can
contribute to spray drift. Dr. Lebowitz suggested modifying that
suggested language to read as “… and will be one of the reasons for
an increase in spray drift.” Board members supported this change. 

Dr. Philpott noted concerns about the next paragraph, which begins,
“The fourth limitation is the need to rely on model accuracy for
estimates to be interpretable.” Dr. Philpott commented that Mr.
Crowley had recommended changing the interpretation by including a more
detailed description of slopes and intercept in the equation, and asked
Dr. Young and Dr. Johnson if they agreed with this recommendation. Dr.
Young concurred, noting this was a special case of proportionality in
which the proportional constant is 1. Dr. Johnson suggested a change to
the second to last sentence in the paragraph that reads “Because
clusters are part of the study’s design, a random cluster effect
should be included in the model.” Dr. Philpott explained that the
sentence had been changed and now reads “Because clusters are part of
the study’s design, a random cluster effect was included in the
model.” 

In the next paragraph, which begins, “In the Agency’s Review
(Crowley and Sarkar 2011)…”, Dr. Philpott stated that Dr. Johnson
had suggested that the text was unclear and cited as an example the
sentence that reads “First, the expectation of ln(exposure/AaiH) must
be linear.” Dr. Johnson explained that this either had to be a linear
function of the active ingredient handled (AaiH), or the AaiH must be a
constant. Dr. Young agreed. Dr. Philpott suggested that the sentence be
changed to read “the expectation of the ln(exposure/AaiH) must be
constant.” Dr. Johnson noted that this would imply that the log
exposure was a linear function of AaiH. In terms of the sentence,
“Second, for the approach to be valid, there cannot be a cluster
effect,” Dr. Johnson raised the concern that cluster effects are
assumed to be random with a mean of zero so that the mean would not
change with the cluster. Dr. Johnson commented that the variance between
clusters is over and above the variance within clusters. Dr. Young added
that, conditional on the cluster, the mean would not be the same.
Because the conditional mean may change, there will be more variation
than anticipated under the log normal distribution if only the “y”s
were modeled. The sentence should read “Second, for the approach to be
valid, the mean response for log normal exposure over AaiH should be the
same for every cluster.” The next sentence now reads “Otherwise the
conditional mean of the distribution would change with the cluster so
that a single log normal distribution would not describe the normalized
exposures.” Dr. Philpott asked if members had an alternate sentence to
propose. Dr. Young suggested that this sentence read “Otherwise, a
single log normal distribution would not describe the normalized
exposures.” Dr. Philpott noted that the HSRB members also were
concerned about the graphs not being labeled, making it difficult to
ensure that the data corresponded with the inhalation data for which
significant cluster effects were present. Dr. Philpott recommended that
the relevant sentence be changed to read as “the graphs as presented
to the Board,” instead of “the graphs.” Dr. Philpott asked if any
members had further comments on the statistical rationale provided to
the Agency. There were no additional member concerns or comments about
the recommendations or rationale for the science charge questions. 

Dr. Philpott explained that the ethics charge question for this protocol
asked whether the available information supported a determination that
the studies were conducted in substantial compliance with 40 Code of
Federal Regulations (CFR) Part 26, subparts K and L. The Board concluded
that it concurred with the Agency’s assessment that the study was
conducted in substantial compliance with subparts K and L. Dr. Philpott
noted that this study was conducted, for the most part, in a way that
did not deviate significantly from the protocol, the SOPs, or the
governing documents. There were no additional member comments about the
recommendations or rationale for the ethics charge question. 

Assessment of Completed Antimicrobial Exposure Assessment Task Force
(AEATF II) Research Study AEA02: Measurement of Potential Dermal and
Inhalation Exposure During Application of a Liquid Antimicrobial
Pesticide Product Using Trigger Spray and Wipe or Ready-to-Use Wipes for
Cleaning Indoor Surfaces

During the April 2011 HSRB meeting, the Board was asked to address two
science charge questions regarding the completed AEATF II study. The
first charge question asked whether the research reported in the
completed AEATF II wipe study report was faithful to the design and
objectives of the protocol and governing documents of the AEATF II
study. The Board concluded that the research reported in the completed
study report and associated supplemental documents was conducted in a
manner that was reasonably faithful to the design and objectives of the
protocol and governing documents of the AEATF II study. The second
charge question asked whether the Agency had adequately characterized,
from a scientific perspective, the limitations on these data that should
be considered when using the data to estimate the exposure of those who
clean indoor surfaces with antimicrobial pesticides using a trigger
bottle and wipes or ready-to-use wipes. The Board concluded that the
Agency had adequately, but not completely, considered the limitations on
these data when using the data to estimate the dermal and inhalation
exposures of antimicrobial handlers who are applying pesticides using a
trigger spray and wipes or ready-to-use wipes. Dr. Philpott received
comments from Board members on this section, all of which have been
incorporated into the draft final Board report, including Dr.
Johnson’s question about whether “amount used” was meant rather
than “amount.” 

	The final sentence in the first paragraph under the detailed
recommendations and rationale states that “The Agency’s analysis of
the data, especially their use of adjustments for the fortified samples
(of which there were more than a few) was an improvement.” Dr. Sidney
Green suggested to Dr. Janice Chambers that the word “adjustment”
was vague, especially to someone who had not seen EPA’s science
review, and commented that the wording could be more explicit. Dr.
Chambers stated that the sentence referred to the use of the level of
quantitation (LOQ) or half LOQ, which is part of the Agency’s standard
way of addressing non-detectable results. Dr. Lebowitz noted that EPA
had recalculated some of the values based on what was found in the
fortified samples and not just the half LOQ. The study accounted for
samples with readings that were not expected, and so the actual estimate
of exposure calculation used an adjustment based on what was done in the
quality assurance/quality control (QA/QC). This is what the sentence was
trying to explain using as few words as possible. Dr. Chambers noted
that non-detectable results needed to be mentioned, and Dr. Lebowitz
responded that it was a different issue. Mr. Tim Leighton (EPA, OPP)
stated that the data were corrected for the field recovery samples. The
Board agreed to changes that included the removal of the parenthetical
clause and mention of QA/QC. Dr. Philpott noted that the sentence now
reads “The Agency’s analysis of the data, especially their use of
adjustments in the QA/QC field recovery samples, was an improvement in
estimating exposure based on actual monitoring.”

	Dr. George Fernandez noted that on page 16 of the draft final Board
report, the first sentence of the paragraph that begins “The results
of the non-parametric bootstrap…”, seemed unclear. Dr. Young
commented that the difference between the non-parametric and parametric
bootstrap is that in one, a distribution is assumed. Dr. Lebowitz stated
that this sentence came directly from the EPA review report in which EPA
stated acceptance of the parametric bootstrap results in terms of the
confidence intervals (CIs); the CIs using the non-parametric bootstrap
were smaller and tighter. He noted that using the tighter CIs with the
non-parametric bootstrap method would be more appropriate, but that EPA
chose to reject the tighter CIs. Dr. Philpott noted that Dr. Lebowitz
had recommended that the Agency may want to use the non-parametric
bootstrap results. Mr. Leighton stated that EPA had taken the comments
and had run both a non-parametric and a parametric bootstrap. Dr.
Philpott noted his concern that the matter was not discussed in detail
at the April 2011 Board meeting, and asked Dr. Fernandez, Dr. Young and
Dr. Johnson if they agreed with this conclusion, as it appears that the
Agency already is acting on the recommendation. Dr. Young commented
that the limitations of the study were discussed at the April 2011 Board
meeting. She asked about the log normal distribution, and how much
information the Board needs to repeat, because statistically, many of
the ideas go from one study to the next. Dr. Philpott answered that he
did not want the Agency or the sponsors to think that this is not a
concern, and suggested the addition of the following sentence toward the
end of the detailed discussion and rationale: “The same concerns about
the use of a log normal distribution raised by the Board in its
discussion of the AHETF open cab airblast study also apply here.”
Dr. Young asked whether it would be better to cite both log normal
distribution and cluster effects. The Board agreed to amend the proposed
sentence to add “single” to log normal distribution.

The ethics charge question asked whether available information regarding
the AEATF II study supports a determination that the study was conducted
in substantial compliance with 40 CFR Part 26, subparts K and L. The
Board concurred with the Agency’s assessment that the study was
conducted in substantial compliance with the applicable requirements.
The Board noted that there were some minor protocol deviations,
including two unreported deviations, but concluded that they did not
compromise either the informed consent process or put the study
participants at additional risk. Dr. Vanessa Northington Gamble noted
that on page 19 of the draft final Board report, Ms. Kelly Sherman (EPA,
OPP) had suggested changing the term “patient” to “subject.” Dr.
Philpott explained that a change was made, substituting the word
“participant” for “patient” throughout the report. 

Assessment of Published Research Study by Gulson et al. (2010): Small
Amounts of Zinc From Zinc Oxide Particles in Sunscreens Applied Outdoors
Are Absorbed Through Human Skin

Dr. Philpott noted that the study status had been changed from
“completed study” to “published study.” He received a number of
minor comments and corrections from both Board members and the Agency,
and most of these comments and corrections had been incorporated into
the draft final Board report. The HSRB was asked to address two
scientific charge questions. The first charge question asked whether the
Gulson et al. study was scientifically sound and provided reliable data.
The second charge question asked that, if the answer to the first
question was affirmative, whether the Gulson et al. study was relevant
for qualitative use in support of an assessment of the absorption of
zinc oxide through the skin. The Board concurred with the Agency’s
assessment that the Gulson et al. study provides some potentially useful
data on the dermal absorption of zinc from zinc oxide nanoparticles in
sunscreen applied to human skin despite the multiple limitations
identified by the HSRB. The Board advised the Agency to proceed with
caution in using these data for risk assessment as they cannot be used
as a stand-alone data set to assess dermal absorption of zinc oxide.
Limitations and concerns included: not accounting for certain variables
such as frequency and time of garment changes, activities affecting
exposure and, in particular, potential contamination of urine samples
with sunscreen from the participants’ hands (supported by the fact
that the applicator also exhibited evidence of dermal absorption of the
zinc). There were a number of other methodological and statistical
concerns raised that led the HSRB to question the statistical validity
of the data and the researcher’s conclusions. Thus, the Board
recommended that the data be treated as exploratory in nature and that
the Agency look for further studies to confirm the conclusion that zinc
oxide formulated as nanoparticles can be absorbed through the skin in
this manner. 

On the top of page 22 of the draft Board report, the Agency raised some
questions and included some comments in highlighted areas. Dr. Philpott
observed that the OPP rightfully noted that the study investigators, not
the Agency, speculated as to how contamination of the urine samples
could have occurred and the Agency simply included that speculation in
its report. Dr. Chambers noted that the paragraph that begins
“Regarding gender-related differences in dosing…”, also has a
highlighted section at the end. In this paragraph, the Agency added
information not discussed at the April 2011 Board meeting; Dr. Philpott
and Dr. Chambers agreed that this additional language should not be
included. The Board members agreed with the proposed deletion. Dr.
Jessica Ryman (EPA, OPP) noted that the comment had been added because
the start of the paragraph suggests that the authors provided
insufficient information for readers to determine whether there was any
interaction between an individual’s body weight and a significant
difference in the dose. The proposed sentence was added because the
calculation of the change in the percentage of the 68Zn isotope included
a body mass index calculation in the study review; that body mass index
calculation would take into account individual body weights and gender.
Dr. Ryman did not recall discussion at the April HSRB meeting regarding
insufficiency of data to reach conclusions about differences between the
genders, but the study  results discuss how both gender and body weight
were considered in the calculations. Dr. Philpott expressed
understanding of the Agency’s position on this matter, and
acknowledged that the EPA analysis did note that there was an accounting
for differences in gender and body weight by adjusting for fat-free body
mass. Dr. Popendorf added that the sentence right before the proposed
addition states “…but not when comparing their total Zn content in
whole blood using the subject’s weight”, and that this sentence says
the same thing (without including gender). Dr. Philpott stated that
this comment means that the Board did consider the impact of both weight
and gender, and asked if a change to the sentence could be made that
would accurately reflect the HSRB’s conclusions without incorporating
additional material that was not discussed at the April 2011 meeting.
Dr. Popendorf suggested the following change: “…but not when
comparing their total Zn (Δ68Zn %) content in whole blood using the
subject’s weight and gender.”

The Agency also recommended clarification of the sentence in the next
paragraph that states “The researchers performed a log transformation
to correct this high degree of skewedness, which may be caused by this
single outlier,” by adding “This transformation revealed that values
from subject 7 were within the range of similarly transformed values
from other subjects.” Dr. Philpott asked if this was an accurate
assessment of the Board’s discussions and conclusion on the skewedness
caused by the data on subject 7. Dr. Fernandez stated that it was not
clear how this calculation was being made and it was not discussed
explicitly at the April 2011 Board meeting. Dr. Young suggested that the
proposed addition should not be included, and Dr. Fernandez agreed. Dr.
Lebowitz asked if the additions and changes in that paragraph made by
the Agency have been removed, and Dr. Philpott answered that they had. 

In its ethics charge, the Board was asked to consider whether there was
adequate information to determine that the Gulson et al. study was
conducted in substantial compliance with procedures at least as
protective as those in EPA regulations at 40 CFR Part 26, subparts A
through L. This is a challenging question because this is the first
post-rule study from the published literature, this study was conducted
in Australia and the HSRB is asked to consider the question of whether
or not there is sufficient information to determine whether the study
was conducted in substantial compliance with procedures at least as
protective as the EPA regulation. The HSRB concluded that currently
there is insufficient information to determine whether the Gulson et al.
study was conducted in substantial compliance with procedures at least
as protective as those in 40 CFR Part 26, subparts A through L. The
Board recommended that the Agency seek additional information from
Macquarie University where the study originated, including acquisition
of a copy of the research protocol and an unsigned consent form to
enable the Board to conclude whether the study was conducted in
substantial compliance with procedures as least as protective as those
in the EPA regulations. Dr. Philpott noted that the Board recognizes
that the research was reviewed and approved by Macquarie University
Human Research Ethics Committee, which is registered with the Australian
National Health and Medical Research Council, and that the HSRB believes
that the study likely was conducted in substantial compliance with very
protective regulations, but the Board does not have enough information
at this time to determine the answer to this question. 

Regarding the paragraph on page 25 of the draft final Board report that
begins “The HSRB determined that most of the information that the
Board has about the ethical conduct of the Gulson et al. (2010) study is
without supporting documentation and is thus inferential,” Dr.
Popendorf asked whether “inferential” referred to the information or
the conclusions. Dr. Philpott asked Dr. Sharpe for wording to clarify
“inferential.” The affected portion of the sentence will be changed
to read “…is without supporting documentation and thus any
conclusions about the ethical conduct of the study would be
inferential.” There were no further Board member comments on the
ethical charge. 

Reconsideration of Two Concerns Previously Raised by the HSRB in Its
June 2009 Review of a Pre-Rule Intentional Human Dosing Study Involving
Chlorpyrifos (Kisicki et al. 1999)

Dr. Philpott received a number of clarifying comments and edits from
Board members on the Kisicki et al. study and they have been
incorporated into the final version of Appendix I of the draft final
Board report. Dr. Chambers explained that the Board revisited two
concerns from a study discussed in the June 2009 Board meeting: whether
the urine may not have been hydrolyzed and therefore the urinary
metabolite was inaccurate and whether, because of that fact, lower
absorption made sense. The Dow Chemical Company presented some
scientifically plausible information on both of those points. Therefore,
the HSRB is revisiting the conclusions on those two points: that it was
logical for the larger particles of chlorpyrifos to be absorbed more
slowly, which could have explained the difference in absorption, and
that quantitation of the urinary trichloropyridinol (TCP) was accurate
because the procedure was correct. Dr. Philpott added that the Board
concluded that the two other concerns discussed at the June 2009 Board
meeting, although not as substantial, remain unaddressed and there are
still concerns about the reliability and utility of the blood and urine
measurements of chlorpyrifos and TCP in the Kisicki et al. study if used
for risk assessment purposes. 

Dr. Popendorf noted that the following sentence is factually correct: 
“The quantitation of urinary TCP was accurate because the urine was
subjected to acid hydrolysis and heat to liberate conjugated TCP.”
However, Dr. Popendorf further noted that, in the original June 2009
report, the Board reached a conclusion that the handling contributed to
the differences in the two studies, and what is not mentioned is that
the conclusion was changed. He would like to clarify that, with new
information received, a different conclusion was reached. Dr. Chambers
asked if  Dr. Popendorf was proposing to add a sentence that the urinary
TCP data do not contribute to the differences. If so, Dr. Chambers
remarked that she was uncomfortable with the proposed change because the
study was not reanalyzed in its entirety. Dr. Lebowitz agreed with Dr.
Chambers. Dr. Philpott noted that the main concern was that the June
2009 meeting report, which is published and public, potentially contains
some erroneous information. The goal of the proposed change is to
correct that report, not reevaluate the Board’s earlier conclusions or
the study in its entirety. He agreed that the statement should not be
added. Dr. Green also agreed. 

Draft Letter from an HSRB Workgroup on Providing Research Participants
with Individualized Study Results

The AEATF II mop study promised to provide individualized exposure data
to the participants, upon request. The Board convened a workgroup to
examine this issue and the broader question of reporting individualized
exposure results to participants in intentional exposure studies. The
workgroup continues to examine the broader issue, but because the AEATF
II mop study has been completed, the workgroup has developed a draft
letter for AEATF II mop study participants.

Dr. Sharpe presented to the Board  a draft letter for the mop study
participants (dated April 27, 2011) to be forwarded the AEATF II. The
letter was developed to be sensitive to the reading level of the
participants, be simple and clear, provide information about individual
exposure results relative to others in the study and provide some
context for the individual. Dr. Sharpe left several comments in the
draft letter for discussion. One sentence in the draft letter states
that everyone who participated in the study had different exposures, but
all had exposures that EPA considers safe. She asked Dr. Rebecca Parkin
to discuss whether it was appropriate to include the word “safe” or
“acceptable” in this letter. Dr. Parkin commented that the word
“safe” has been controversial in environmental protection and health
issues because it means different things to different people. There has
been a trend toward the word “acceptable” rather than “safe”
because it does not imply total safety, but only that the various
aspects of exposure have been considered and the exposure has been
determined to be acceptable. Dr. Green agreed that “acceptable” is
a better choice than “safe” because safety cannot be guaranteed.
Other Board members agreed. Dr. Philpott will make the change in the
draft letter. 

Dr. Sharpe noted that the draft letter included a bar chart to provide a
scale of lowest to highest exposure; this will be marked with a vertical
line to show the individual participants where their skin and breathing
exposure are on the continuum of lowest to highest exposure.
Instructions were provided in the margins of the draft letter as to how
to complete the bar chart to communicate with each individual. Dr.
Chambers commented that if most participants were on one end of the
scale and one person on another, then the bar chart might provide a
skewed idea to the person requesting the information. Dr. Young agreed.
Dr. Chambers added that an outlier at the highest or lowest point might
give participants a false sense of alarm or security if the individual
did not know where all the others are located. Dr. Sharpe asked if Dr.
Chambers would agree that it is not advisable in a letter like this to
note everyone’s exposure. Dr. Chambers responded that participants
would not know how the group is arranged if everyone’s exposure were
not included. Dr. Parkin noted that she had proposed that letters be
pretested, because the Board could be wrong about their assumptions for
the target audience. She noted that what was drafted was a proposal, or
suggestion, for how the results could be presented, and the AEATF II mop
study needs to test the letter before using it. Dr. Young agreed that
field testing would be useful, but the Board should answer this issue
otherwise there might need for a different bar graph on every letter
depending on whether there are outliers. Dr. Popendorf suggested a
straight line without the “dumbbells” at each end, and insertion of
a triangle for the average or mean to provide more information. Dr.
Young suggested that if the median were used instead of the mean, that
would be acceptable. Dr. Sharpe added that the letter would need to
explain the median if it were to be used. Dr. Philpott noted that the
Board likes the simplified graphic approach, and suggested adding a
point on the bar chart that identifies the median. Arrows could show
dermal and breathing exposure on two different graphs. 

A recommendation could be made to the AEATF II mop study that the letter
be field tested among people similar to the study participants. Dr.
Sharpe asked whether the Board should have a role in testing the draft
letter to study participants or to review the letter the AEATF II mop
study would produce as a result of the feedback from draft letter
testing. Dr. Philpott responded that the Board could offer to do this,
but the sponsors and the Agency are under no obligation to come back to
the HSRB to do so. 

Dr. Sharpe noted that, during Working Group discussions, Dr. José
Manautou had commented that if the participants were being told to
improve their mopping technique then the letter should provide some
information on how to do so. This raised the question whether there is
EPA guidance about mopping, such as a brochure that could be included
with the letter, or instructions from the product manufacturers that
could be included. Mr. Downing concurred with the comment and thought
that the AEATF II mop study had some suggested techniques to lessen
exposure that could be included. Dr. Chambers suggested that if the
exposure of most participants was similar, the letter should just
acknowledge that the participant’s exposure was similar to most and
the participants should not receive different letters. Dr. Philpott
responded that if a person received a lower exposure than most, the
Board does not want them to relax and to cease protecting themselves. He
commented that there had to be different letters: one that recommends
the participant maintain current techniques and another that suggests
ways to improve. Dr. Sharpe suggested adding another sentence to the
draft letter (below the specific information about the individual’s
exposure) that states, for example: “For your information, we are
including material about mopping techniques to keep exposures as low as
they can be.” However, such an approach would mean that all
participants would get the same information in the letter, whether they
were above or below the median. Alternatively, the letter could note
whether the participant was above, below, or “near the middle” of
most of the participants in terms of exposure. Dr. Popendorf added that
there could be a sentence describing the middle mark. Dr. Sharpe
commented that a sentence would be needed to explain the median.
Dr. Philpott suggested that he and Dr. Sharpe craft this sentence. 

Dr. Green noted that the sentence after “Your exposure was higher than
most…” further stating that “This does not put you at any
short-term risk…” is too definite. Dr. Green suggested revising
“does not” to “may not”, because it would be more accurate.
Dr. Philpott agreed to make this change. 

Dr. Philpott noted that two votes needed to be taken. The first vote was
to approve the draft final Board report as amended during this
teleconference meeting. All Board members present on this teleconference
meeting approved the report except for Dr. Parkin who abstained as she
was not present at the April meeting. The second vote was whether to
send to the draft letter, including changes suggested in this
teleconference meeting, to the AEATF II mop study with the strong
recommendation that it be field tested before use. All Board members
present on this teleconference meeting approved the draft letter, with
the changes identified, and the pretesting recommendation. Dr. Philpott
and Dr. Sharpe, along with Dr. Parkin, will make the changes.

Summary and Next Steps

Mr. Downing noted that the next face-to-face HSRB meeting would be held
on October 18-21, 2011. 

Dr. Philpott thanked the Board members for their participation. The
teleconference meeting was adjourned by the Chair at 3:09 p.m.

    The HSRB is a Federal advisory committee operating in accordance
with the Federal Advisory Committee Act (FACA) 5 U.S.C. App.2 section 9.
The HSRB provides advice, information, and recommendations to EPA on
issues related to scientific and ethical aspects of human subjects
research. The major objectives of the HSRB are to provide advice and
recommendations on: (1) Research proposals and protocols; (2) reports of
completed research with human subjects; and (3) how to strengthen 

EPA's programs for protection of human subjects of research. The HSRB
reports to the EPA Administrator through the EPA Science Advisor.    1.
Topics for Discussion. The HSRB will be reviewing its draft report from
the April 13-14, 2011 HSRB meeting. The Board may also discuss planning
for future HSRB meetings. Background on the April 13-14, 2011 HSRB
meeting can be found at Federal Register Volume 76, Number 59 (Monday,
March 28, 2011), pages 17121-17123) and at the HSRB Web site   HYPERLINK
"http://www.epa.gov/osa/hsrb/"  http://www.epa.gov/osa/hsrb/ . The April
13-14, 2011 meeting draft report is now available. You may obtain
electronic copies of this document and certain other related documents
that might be available 

electronically from the   HYPERLINK "http://www.regulations.gov" 
http://www.regulations.gov  Web site and the HSRB Internet home page at 
 HYPERLINK "http://www.epa.gov/osa/hsrb"  http://www.epa.gov/osa/hsrb .
The HSRB will also review and consider a draft letter providing
participants with individualized study results that was provided at a
previous HSRB meeting. The HSRB was asked to provide feedback on the
letter that will be sent to the participants from the Antimicrobial
Exposure Assessment Task Force II that measured the amount of
antimicrobial cleaning products on participants' skin and the amount
they breathe in while mopping floors.

The Board’s response to EPA charge questions presented at the April
13-14, 2011 meeting.

Completed AHETF research on exposure of workers applying pesticide
sprays using open‐cab airblast equipment.

Charge to the Board:

•	Was the research reported in the Agricultural Handler Exposure Task
Force (AHETF) completed monograph report and associated field study
reports faithful to the design and objectives of the protocol, SOPs, and
governing documents?

•	Has EPA adequately characterized, from a scientific perspective, the
limitations on these data that should be considered when using the data
in estimating exposure of those who apply pesticides with open cab
airblast equipment?

•	Does the available information support a determination that the
studies were conducted in substantial compliance with subparts K and L
of 40 CFR Part 26?

*Note that agenda times are approximate. For further information, please
contact the Designated Federal Officer for this meeting, Jim Downing via
telephone: (202) 564-2468 or email: downing.jim@epa.gov

Completed AEATF research on exposure of professional janitorial workers
when

wiping indoor surfaces with an antimicrobial pesticide.

Charge to the Board:

• 	Was the research reported in the Antimicrobial Exposure Assessment
Task Force

	II (AEATF) completed wipe study report faithful to the design and
objectives of

	the protocol and governing documents of AEATF?

• 	Has EPA adequately characterized, from a scientific perspective,
the limitations

	on these data that should be considered when using the data in
estimating

	exposure of those who clean indoor surfaces with antimicrobial
pesticides using a

	trigger-spray bottle and wipes or ready-to-use wipes?

• 	Does the available information support a determination that the
study was

	conducted in substantial compliance with subparts K and L of 40 CFR
Part 26?

Assessment of Published Research Study by Gulson et al. (2010): Small
Amounts of

Zinc From Zinc Oxide Particles in Sunscreens Applied Outdoors Are
Absorbed

through Human Skin.

Charge to the Board

• 	Is the Gulson et al. (2010) study scientifically sound, providing
reliable data?

• 	If so, is the Gulson et al. (2010) study relevant for qualitative
use in support of an

	assessment of the absorption of zinc oxide through the skin?

• 	Is there adequate information to determine that the Gulson et al.
(2010) study was

	conducted in substantial compliance with procedures at least a
protective as those

	in subparts A - L of EPA’s regulation at 40 CFR Part 26?

Reconsideration of two concerns previously raised by the HSRB in its
June 2009

review of an intentional human dosing study with chlorpyrifos (Kisicki
et al., 1999);

additional pertinent information was made available by the sponsor
related to these

two concerns.

Issues for Discussion:

• 	Do the recommendations provided by the HSRB at its June 2009
meeting and in

	its subsequent report regarding the reliability of data on the urinary
metabolite

	trichloropyridinol in the Kisicki et al. (1999) study change in light
of the new

	information provided?
