Dr. Janice Britt is a Managing Scientist with the Center for 21st Century Toxicology and is based in Tallahassee, Florida. She has over 20 years of experience in toxicology and has worked in the areas of human and animal toxicology, chemical exposure assessment, risk assessment, and causation analysis. Dr. Britt is familiar with and has published in the areas of systematic review, evidence integration, and Evidence-based Toxicology. Dr. Britt has critically evaluated the toxicity of numerous chemicals, pharmaceuticals, food products, and medical devices. She has been involved in the critical evaluation of exposures involving hazardous waste sites, environmental contamination situations, occupational exposures, and agriculture-related product exposures. Specifically, Dr. Britt has conducted comprehensive toxicity evaluations of compounds such as benzene, toluene, chlorinated solvents (e.g., trichloroethylene, tetrachloroethylene, and vinyl chloride), formaldehyde, PFAS compounds (PFOA/PFOS), insecticides, herbicides, dyes, acrylamide, heavy metals (e.g., arsenic, lead, manganese, and mercury), polychlorinated biphenyls (PCBs), carbon disulfide, asbestos, silica, carpet emissions, caprolactam, phosphogypsum, ammonia, carbon monoxide, as well as a variety of pharmaceutical agents, herbal products, cosmetics, and food additives. In addition to evaluating the toxicity of specific chemicals, Dr. Britt has conducted toxicity assessments to evaluate the hazards associated with different occupations and exposures, including painting, welding, printing work, photo processing work, mining, sandblasting, petroleum refinery work, and hydraulic fracturing. Dr. Britt has also performed site-specific risk assessments, developed toxicological profiles for various chemicals, evaluated various regulatory toxicity criteria, and developed safe levels of exposures for chemicals.
Previously, Dr. Britt worked as the toxicologist for the Florida Department of Agriculture and Consumer Services, where she reviewed toxicity data and made regulatory decisions regarding the registration of pesticides for the State. While at the Department, she conducted assessments to evaluate the potential risks associated with exposures to pesticides and other chemicals (e.g., glycol ethers, chlorinated solvents, and inert ingredients) on various receptors (humans, mammals, birds, and aquatic species). She served as a toxicologist on the Florida Pesticide Registration Evaluation Committee, which is responsible for conducting scientific and technical reviews of pesticide product registrations for the State of Florida. She played an active role in developing a regulatory procedure for ranking pesticides according to their chronic toxicity and leaching potential, an approach that was published in the peer-reviewed literature.
