Abstract: As part of its mission the Center for Computational Toxicology and Exposure (CCTE) at the US Environmental Protection Agency delivers access to chemicals related data via online Dashboards. The CompTox Chemicals Dashboard (available at https://comptox.epa.gov/dashboard) provides access to >1.2 million chemicals and associated data including experimental and predicted property data, in vivo hazard data, in vitro bioactivity data, exposure data, and various other data types. The application provides a set of flexible searches allowing for search, visualization and downloads of the data to the desktop for further interrogation. Over 400 chemical lists are integrated into the Dashboard associated with chemical classes (e.g., pesticides and flame retardants), regulatory lists (e.g., Integrated Risk Information System (IRIS) and the Toxics Release Inventory (TRI)) and various iterations of the Toxic Substances Control Act (TSCA) lists for both active and inactive subsets. The TSCA list offers many challenges in terms of managing chemicals related data including the fact that many chemicals cannot be represented as chemical structures but are members of the UVCB class (Unknown or Variable Composition, Complex Reaction Products and Biological Materials). Many surfactants are contained within the UVCB classes and advanced cheminformatics approached have been applied to deal with such data. This presentation will provide an overview of the Dashboard and the delivery of data associated with the TSCA inventory to the scientific community. This presentation will also introduce a number of proof-of-concept modules in development.
