Computational Toxicology Research
EPA's Computational Toxicology research (CompTox) is part of EPA's broader Chemical Safety research efforts. Traditional chemical toxicity testing is expensive, time consuming and uses a significant number of animals. CompTox is researching new, more efficient, ways to address managing the safety of chemicals, particularly in assessing chemicals for potential risk to human health and the environment. Read More
System Models for Chemical Toxicity and Exposure
Researchers collect new types of data on the biological effects of large numbers of untested chemicals using innovative technologies such as automated-rapid chemical screening. Virtual models are being developed to predict the body's potential responses to different chemicals.
Dashboards, Models and Tools
Researchers provide sophisticated models, databases and tools that are used to inform chemicals related regulatory and policy decisions.
Inherent Chemical Properties
The Distributed Structure – Searchable Toxicity (DSSTox) network is helping to build a public data foundation for improved chemical structure-activity and predictive toxicology capabilities.
Chemical Safety Research Grants & Funding
EPA's Science to Achieve Results or STAR program provides funding to research centers in specific areas of chemicals related research.
