Dr. Linda C. Hall is a human health toxicologist with extensive experience providing toxicology and risk assessment expertise to clients in both the public and private sectors. Dr. Hall has actively followed the emerging science of per and polyfluoroalkyl substances (PFAS) toxicology, and is in her ninth year with the Interstate Technology and Regulatory Council (ITRC) PFAS team as co-leader of the Human and Ecological Effects group. In that role, she serves as an editor, contributing author, and coordinating manager of Fact Sheets and chapters of the Technical Regulatory Guidance document which address human health, ecological toxicology, and risk assessment of PFAS. Dr. Hall has testified in PFAS litigations regarding potential human exposure and health effects of PFAS released during manufacturing. Dr. Hall has also worked as a technical expert on the toxicology of PFAS on multiple litigations that have involved human exposure to PFAS from manufacturing releases to air and water; from AFFF contamination of soil, drinking water, and food; and on the food chain transfer and potential human health effects of PFAS in crops grown for animal feed on soils amended with biosolids. She has participated as a panelist and/or presenter in numerous seminars on PFAS for clients and to the legal and scientific communities.
Dr. Hall has managed and conducted human health risk assessments under U.S., state, and international regulatory requirements for sites involving potential human exposure to contaminants detected in air, sediment, soil and soil vapor, groundwater, and surface water. She was the lead human health risk assessor for a metal smelter in Jamaica, and has served as a Qualified Person for Risk Assessment (QPRA) in Ontario, Canada, where she directed risk assessments for multiple Brownfield sites and established health effects-based cleanup criteria for numerous contaminants and exposure pathways.
Dr. Hall has conducted, managed, and peer-reviewed health risk assessments for California maritime ports, rail yards, and intermodal facilities, focusing on health impacts from the combustion of diesel and other fuels. Dr. Hall led pesticide health risk assessments for state- and county-wide insect eradication programs that evaluated both conventional and atypical pesticides. She has evaluated health effects associated with exposure to dioxins and dioxin-like compounds, metals, petroleum hydrocarbons, and volatile organic compounds (VOCs), and has developed health-effects based ingestion and inhalation guidelines for these substances. Dr. Hall has led and designed large scale vapor intrusion assessments of residential neighborhoods and an actively-used industrial research complex with extensive subsurface VOC contamination. She has also derived and/or provided peer-review of maximum allowable dose level (MADL) derivations for phthalates and proprietary chemicals under California’s Proposition 65.
For public and private clients, Dr. Hall has prepared risk communication materials; these materials have been used to communicate and interpret the results of toxicological research and human health risk assessments to the public, client corporate and internal staff, and public relations firms.
