Impact/Purpose:
Abstract and presentation for EPA's ENTACT workshop Aug 2018
Description:
Information and data on chemicals is used by scientists to evaluate potential health and ecological risks due to environmental exposures. EPA’s CompTox Dashboard (https://comptox.epa.gov) helps evaluate the safety of chemicals by providing public access to a variety of information on over 760,000 chemicals currently in use. Within the Dashboard, users can access chemical structures, chemistry information, toxicity data, hazard data, exposure information, and additional links to relevant websites and applications. These data are compiled from sources including EPA’s computational toxicology research databases, from public domain databases and with collaborators across the world. Chemical lists have been added that provide access to various classes of chemicals and project-based datasets are under constant development. Specific functionality has been delivered within the Dashboard to support mass spectrometry including “MS-ready forms” of chemical substances that would be detectable by mass spectrometry. Workflows have been developed to assist in candidate identification and have now been proven with multiple published studies. An integration path between the dashboard and MetFrag has also been established to provide users the significant benefits resulting from the marriage between the two applications. The datasets underpinning the dashboard are freely available (https://comptox.epa.gov/dashboard/downloads) for integration into third party databases. This presentation will provide an overview of the available data types and functionality of the dashboard prior to examining how it is developing to support mass spectrometry based analyses within the agency and for the community in general. An overview of the impending release of the dashboard will also be provided. This includes access data for specific classes of compounds of interest to the Agency, the ability to search for chemicals by product use and categories, and the ability to interrogate the ToxCast/Tox21 high-throughput screening bioactivity data based on both assay and gene searches. We will also discuss our present research efforts to enhance the dashboard using in silico MS/MS fragmentation prediction for spectral matching. This abstract does not reflect EPA policy.
