Dr. Janice Britt is a Managing Scientist with ToxStrategies and is based in Tallahassee, Florida. She has more than 20 years of experience in toxicology and has worked in the areas of human and animal toxicology, chemical exposure assessment, dose-response analysis, and risk assessment. Dr. Britt also has extensive experience in the areas of systematic review, causation analysis, and Evidence-Based Toxicology. She recently published a 10-year retrospective on the use of evidence-based methods in assessing causation in toxicology. She has critically evaluated the toxicity of numerous environmental- and occupational-related chemicals, pharmaceutical compounds, over-the-counter medications, dietary supplements, food and beverage products, food additives, herbal products, consumer products, and medical devices. She has evaluated exposures involving hazardous waste sites, chemical releases, environmental exposures, exposures in the home and workplace, as well as agriculture-related exposures. Specific compounds that Dr. Britt has worked with include benzene, toluene, chlorinated solvents (e.g., trichloroethylene, tetrachloroethylene, and vinyl chloride), talc, formaldehyde, chlorine, PFAS compounds (e.g., PFOA and PFOS), pesticides (e.g., acephate, atrazine, carbaryl, chlorpyrifos, cyfluthrin, 2,4-D, DDT, diazinon, dicamba, dichlorvos, diquat, heptachlor, glyphosate, limonene, malathion, methoprene, paraquat, parathion, permethrin, and simazine), paints, petroleum products, dyes, N-nitrosodimethylamine (NDMA), acrylamide, heavy metals (e.g., arsenic, lead, manganese, and mercury), polychlorinated biphenyls (PCBs), carbon disulfide, asbestos, silica, talc, sunscreens, carpet emissions, caprolactam, phosphogypsum, ammonia, fire suppressants, hydraulic fracturing-related compounds, and carbon monoxide, as well as a variety of pharmaceutical agents (e.g., acetaminophen, narcotics), herbal products, and products contained in cosmetics and foods (e.g., diacetyl, food colorants, sweeteners). 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. She 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.
Dr. Britt is a member of the Society of Toxicology, the Society for Risk Analysis, the American Conference of Governmental Industrial Hygienists (ACGIH), and EUROTOX. In addition, she is a European Registered Toxicologist (ERT) and a fellow of the Royal Society of Biology (FSRB). She is currently serving as a member of USEPA’s Human Studies Review Board, which is a federal advisory committee that provides advice and recommendations on issues of human subject research.
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 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.
