Ms. Ann Bradley is a toxicologist and risk assessor with more than 15 years of experience in the health and environmental science fields. Her particular areas of expertise include site- and chemical-specific risk assessments and toxicological assessments. As lead human health risk assessor and toxicologist on her projects, Ms. Bradley provides leadership and direction in all aspects of human health risk assessment under CERCLA and other regulatory programs. She has extensive experience evaluating the potential health impacts of metals, pesticides, PCBs, dioxins, and PAHs through multi-media exposures. Ms. Bradley also leads exposure and toxicological assessments of chemicals in consumer products to support regulatory compliance, including under Proposition 65 (Prop 65). Her work has included the design and implementation of both deterministic and probabilistic (i.e., Monte Carlo) risk assessments aimed at understanding the influences of uncertainty and variability in exposure patterns and risk results.
Ms. Bradley is skilled in conducting toxicological evaluations to develop health-based criteria used to derive cleanup goals. She has successfully petitioned to alter such criteria, and has proposed new criteria for chemicals without established criteria. Her professional interests include determining methods for integrating findings of divergent data types to inform decision-making.
