II. Background

A. Purpose of the Meeting

    This 4-day meeting concerns several scientific issues undergoing
consideration within the EPA, Office of Prevention, Pesticide and Toxic
Substances (OPPTS), as follows:
    1. Test guidelines for chronic inhalation toxicity and
carcinogenicity of fibrous particles: The Agency's current health
effects test guidelines for chronic inhalation toxicity and/or
carcinogenicity studies of chemicals are considered not specific enough
for the testing of fibrous substances. Through an interagency working
group, a workshop was conducted to obtain input from the scientific
community on a number of issues related to fiber testing. Based on the
recommendations from the workshop panel and participants, EPA/OPPT has
developed a proposed standardized study protocol for respirable fibers
which was announced in the Federal Register of July 28, 1999 (64 FR
40871) (FRL-6078-6), for public comments. All public comments have been
evaluated and a revised draft guideline with some of the public
comments incorporated has been prepared. This scientific advisory panel
is charged to review the EPA draft test guidelines, advise on remaining
issues on the study protocol for the health effects testing of fibrous
particles, and provide EPA with an opinion about the scientific
validity of the testing guidance.
    2. Cumulative hazard assessment of organophosphorous pesticides:
The Agency is presenting an approach to assess and select common
mechanism endpoints for accumulating hazard and a method for
determining relative potencies for organophosphate pesticides. The
relative potencies will be used in a cumulative risk assessment of
multiple organophosphate pesticides. The FIFRA SAP is being asked to
advise on advantages and disadvantages of the method used to assess
cumulative hazard and rank the pesticides.
    3. Components and methodologies of the Calendex\TM\, Lifeline\TM\
and REX models, as tools for dietary and residential pesticide exposure
and risk assessments: The purpose of this session is to describe the
algorithms, input data requirements, and output reports associated with
the Residential Exposure (REX) model, and the Calendex software. REX is
a spreadsheet (EXCEL) based model which allows aggregation of multiple
routes (dermal, inhalation, oral) and pathways (product use scenarios)
to estimate exposure and risk from pesticides used in a residential
setting.
    A major requirement of the FQPA is that exposures to pesticides
across various pathways and routes (e.g., dermal exposure through turf
uses) be appropriately combined such that an ``aggregate'' exposure
assessment can be performed. The Agency currently uses Calendex
software from Novigen Sciences to perform this aggregation. The purpose
of this session is to describe the components and methodologies used by
the Calendex software the basic concepts and assumptions behind
Calendex and its algorithms and procedures.
    Aggregate and cumulative exposure assessments to pesticides must
capture the correlation in residues that occur from both additive and
exclusionary processes resulting from use of pesticides. The analysis
also requires a quantitative mechanism for evaluating risks associated
with exposures to time-varying mixtures of pesticides. The purpose of
this presentation is to describe an analysis of aggregate exposures and
risks associated with exposures to a hypothetical pesticide, Alpha, and
the cumulative exposure to and risk from three hypothetical pesticides,
Alpha, Beta, and Gamma. The cumulative risks are evaluated by
determining the systemic (absorbed) doses that result from inhalation,
dermal, and oral exposures to the pesticides. A ``toxicity equivalent''
model of cumulative risk is used to quantitatively evaluate cumulative
risks. Assessments were performed using LifeLine\TM\ Version 1.0. This
model simulates pesticide exposure using an individual-based approach
where daily exposures are evaluated for each person, season, and
location.
    4. Assessment of pesticide concentrations in drinking water and
water treatment effects on pesticide removal and transformation: The
purpose of this session is to present to the Panel a progress report of
ongoing activities associated with the estimation of pesticide
concentrations in drinking water for FQPA aggregate exposure
assessments and the assessment of water treatment effects on pesticide
removal and transformation. Progress reports will be provided on
regression modeling efforts, status of the national drinking water
monitoring program, and preliminary literature survey and evaluation of
different water treatment processes employed in drinking water
production facilities.

B. Panel Report

    Copies of the Panel's report of their recommendations will be
available approximately 45 working days after the meeting, and will be
posted on the FIFRA SAP web site or may be obtained by contacting the
Public Information and Records Integrity Branch at the address or
telephone number listed in Unit I.C. of this document.
