Computational Toxicology Research

Computational Toxicology Research

EPA's Computational Toxicology research (CompTox) is part of EPA's broader Chemical Safety research efforts. Since current chemical testing is expensive and time consuming, only a small fraction of chemicals have been fully evaluated for potential adverse human health effects. CompTox is researching new, more efficient, ways to address managing the safety of chemicals, particularly in assessing chemicals for human health effects. Read More

High-Throughput Chemical Screening, Exposure Prediction Models & Virtual Simulation Models

CompTox's innovative research projects identify important biological processes that may be disrupted by chemicals and tracing those biological disruptions to related dose and human exposure to chemicals.

  • ExpoCast™ – Exposure Forcaster
  • ToxCast™ - Toxicity Forecaster
  • v-Embryo™ – Virtual Embryo
  • DSSTox - Inherent Chemical Properties Data Storage System
  • ToxPi - Toxicological Priority Index
Dashboards, Databases & Models

EPA shares computational toxicology research in open and transparent ways and is publicly available for anyone to access and use.

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.

Press Releases

EPA Awards Almost $11 Million to Advance Chemical Safety Research
EPA announced nearly $11 million in grants to eight universities to develop fast and effective methods to predict a chemical's potential to interact with biological processes that could lead to reproductive and developmental problems, and disruption of the endocrine system.
