Untitled Document Toxicology support includes health effects and toxicology research, development of quantitative toxicity criteria, exposure and risk assessment, sample collection strategies that consider toxicological and risk implications, development of risk-based cleanup criteria, litigation support and risk communication.

Signature Science staff understand the toxicological underpinnings of toxicity criteria issued by Federal and State agencies. We have experience developing acute inhalation benchmarks, emergency response planning guidelines, and water quality criteria. We are adept at performing human health risk assessments and/or risk-based evaluations conducted in support of Resource Conservation Recovery Act (RCRA) and Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) closures for both commercial and government clients. In addition, we have developed expert opinions on toxicological issues in support of litigation, including testifying in contested case hearings and criminal proceedings, and risk communication services.
