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.
