ACToR (Aggregated Computational Toxicology Resource) is EPA's online warehouse of all publicly available chemical toxicity data and can be used to find all publicly available data about potential chemical risks to human health and the environment. ACToR aggregates data from over 1000 public sources on over 500,000 environmental chemicals searchable by chemical name, other identifiers and by chemical structure.
The data warehouse:
Allows users to search and query data from other EPA chemical toxicity databases including:
ToxRefDB (30 years and $2 billion worth of animal toxicity studies).
ToxCastDB (data from screening 1,000 chemicals in over 500 high-throughput assays).
ExpoCastDB (consolidate and link human exposure and exposure factor data for chemical prioritization).
DSSTox (provides high quality chemical structures and annotations).
Includes chemical structure, physico-chemical values, in vitro assay data and in vivo toxicology data.
Includes, but not limited to, high and medium production volume industrial chemicals, pesticides (active and inert ingredients), and potential ground and drinking water contaminants.

ACToR Version 2011Q3 is now online with many new data sets.
ExpoCast DB is now available
ACToR Version 2010 Q4 is now online. We have added many new data sources
"Also new - all assays have been assigned to a set of categories, making browsing through assays (hopefully) mroe informative"
Updated version of the ACToR and ToxRefDB application have been released
Notes have been added to the ToxRefDB page making it more clear that this provides access to only chemicals with full guideline study data - other chemicals need to be accessed through ACToR
Searching for chemicals by CASRN with no dashes now works
We have added a link to allow users to download all information on a chemical as a single pdf - users should note that some of these reports are hundreds of pages long. Be careful what you send to the printer!
