How to Download Drafts of SHEDS-Multimedia (Residential Module) version
4 and Dietary Module version 1.0 from EPA’s Website

The SHEDS dietary and residential modules are now available for download
on the Office of Research and Development's National Exposure Research
Laboratory (NERL) website located at:
http://www.epa.gov/heasd/products/sheds_multimedia/sheds_mm.html (note:
please scroll down about half the page past the SHEDS v.3 section at the
top to the part entitled "Download Drafts of SHEDS-Multimedia
(Residential Module) version 4 and Dietary Module version 1.0" in order
to view the material.)  You will also find a copy of the same material
below with links to the same files.

Download Drafts of SHEDS-Multimedia (Residential Module) version 4 and
Dietary Module version 1.0

Links to download the two modules and their technical manuals and user
guides are provided below. The two modules are undergoing external
scientific peer review by the Federal Insecticide, Fungicide, and
Rodenticide Act (FIFRA) Scientific Advisory Panel (SAP) on July 20-22,
2010. All documents for this meeting are available in the Office of
Pesticide Programs public docket, EPA-HQ-OPP-2010-0383, and all,
excluding the Residential and Dietary Modules executable files, are
available online in the FDMS Docket System located at   HYPERLINK
"http://www.regulations.gov"  http://www.regulations.gov .

The annotated SHEDS SAS code, technical manual, graphical user
interface, and user guide provide a thorough perspective and
understanding of the SHEDS technical and usability aspects. 

SAS version 9.1 or higher is required to run SHEDS-Multimedia version 4
and SHEDS-Dietary version 1.0.

EPA's SHEDS-Residential version 4 model

EPA's SHEDS-Residential version 4 model is a physically-based,
probabilistic model that can simulate for a population of interest
cumulative (multiple chemicals) or aggregate (single chemical)
residential exposures over time via multiple routes of exposure for
different types of chemicals and scenarios. The United States
Environmental Protection Agency, through its Office of Research and
Development, developed and funded SHEDS-Residential version 4 with
assistance from contractor Alion Science and Technology, Inc.

SHEDS-Residential version 4 is one module (along with the separate
SHEDS-Dietary module) of EPA’s more comprehensive human exposure
model, the Stochastic Human Exposure and Dose Simulation model for
multimedia, multipathway chemicals (SHEDS-Multimedia), which can
simulate aggregate or cumulative exposures over time via multiple routes
of exposure (dietary & non-dietary) for different types of chemicals and
scenarios. SHEDS-Residential and SHEDS-Dietary will be merged together
in a future version of SHEDS-Multimedia.

SHEDS-Residential version 4 includes a case study example for
illustrative purposes, as well as a default file for non-chemical
specific inputs, as described in the Technical Manual and User Guide.
All input values used in the SHEDS-Residential model for a given
application should be entered or reviewed by the researcher so that the
model results are based on appropriate data sources for the given
application.

Version 4 of SHEDS-Residential reflects comments from EPA's August 2007
FIFRA SAP that reviewed SHEDS-Multimedia version 3 (the aggregate
residential version)[  HYPERLINK

http://www.epa.gov/scipoly/sap/meetings/2007/081407_mtg.htm ]. SHEDS
Residential version 4 will undergo external peer review by EPA's FIFRA
SAP July 20-22, 2010, and should be considered draft at this time.

EPA's SHEDS-Dietary model version 1

EPA's SHEDS-Dietary model is a probabilistic, population-based dietary
exposure assessment model that simulates individual exposures to
chemicals in food and drinking water over different time periods (e.g.,
daily, yearly). SHEDS-Dietary is one module (along with the separate
SHEDS-Residential module) of EPA’s more comprehensive human exposure
model, the Stochastic Human Exposure and Dose Simulation model for
multimedia, multipathway chemicals (SHEDS-Multimedia), which can
simulate aggregate or cumulative exposures over time via multiple routes
of exposure (dietary & non-dietary) for different types of chemicals and
scenarios. SHEDS-Residential and SHEDS-Dietary will be merged together
in a future version of SHEDS-Multimedia.

SHEDS-Dietary version 1 includes case study examples for illustrative
purposes, as described in the Technical Manual and User Guide. All input
values used in the SHEDS-Dietary model for a given application should be
entered or reviewed by the researcher so that the model results are
based on appropriate data sources for the given application.

Through its Office of Research and Development, the United States
Environmental Protection Agency developed and funded the SHEDS-Dietary
module with assistance from contractor Alion Science and Technology.
SHEDS-Dietary Version 1 will undergo external peer review by EPA's FIFRA
SAP July 20-22, 2010, and should be considered draft at this time.
