What We Do

The Chemical Characterization and Exposure Division (CCED) performs research to develop and advance experimental chemistry approaches that are critical to the rapid characterization of the presence, structural characteristics, and properties of chemicals that are of interest to EPA scientists due to their potential environmental fate and toxicity. In addition to chemical characterization, CCED develops computational models to predict external exposure and internal doses for large numbers of chemicals based on minimal data.

CCED strives to reduce the time to conduct toxicity and exposure assessments from years to months by developing:

  • Chemoinformatic tools and knowledgebases
  • Rapid analytical methods for identifying environmental chemicals in environmental and biological samples
  • Predictive models of both exposure and dose for environmental chemicals
  • Absorption, Distribution, Metabolism and Excretion approaches for environmental chemicals and model parameterization
