EPA Improves Access to Information on Hundreds of Chemicals

Searchable databases on chemical toxicity and exposure data now

WASHINGTON - The U.S. Environmental Protection Agency (EPA) is making it
easier to find data about chemicals. EPA is releasing two databases -
the Toxicity Forecaster database (ToxCastDB) and a database of chemical
exposure studies (ExpoCastDB) - that scientists and the public can use
to access chemical toxicity and exposure data. Improved access supports
EPA Administrator Lisa P. Jackson's priorities of protecting Americans'
health by assuring the safety of chemicals and expanding the
conversation on environmentalism.

"Chemical safety is a major priority of EPA and its research," said Dr.
Paul Anastas, assistant administrator of EPA's Office of Research and
Development. "These databases provide the public access to chemical
information, data and results that we can use to make better-informed
and timelier decisions about chemicals to better protect people's

ToxCastDB users can search and download data from over 500 rapid
chemical tests conducted on more than 300 environmental chemicals.
ToxCast uses advanced scientific tools to predict the potential toxicity
of chemicals and to provide a cost-effective approach to prioritizing
which chemicals of the thousands in use require further testing. ToxCast
is currently screening 700 additional chemicals, and the data will be
available in 2012.

ExpoCastDB consolidates human exposure data from studies that have
collected chemical measurements from homes and child care centers. Data
include the amounts of chemicals found in food, drinking water, air,
dust, indoor surfaces and urine. ExpoCastDB users can obtain summary
statistics of exposure data and download datasets. EPA will continue to
add internal and external chemical exposure data and advanced user
interface features to ExpoCastDB.

The new databases link together two important pieces of chemical
research - exposure and toxicity data - both of which are required when
considering potential risks posed by chemicals. The databases are
connected through EPA's Aggregated Computational Toxicology Resource
(ACToR), an online data warehouse that collects data on over 500,000
chemicals from over 500 public sources.

Users can now access 30 years worth of animal chemical toxicity studies
that were previously only found in paper documents, data from rapid
chemical testing, and various chemical exposure measurements through one
online resource. The ability to link and compare these different types
of data better informs EPA's decisions about chemical safety.
