Risk Assessment Syllabus: Basics of Exposure Assessment

Thursday, August 3, 2023
Hosted by: SOT Risk Assessment Specialty Sections

Time: 11:00 AM to 1:00 PM (US EDT, UTC -4)

Speaker(s):
Nicolle Tulve, PhD, US EPA
Dan Vallero, PhD, US EPA

Risk assessment is a multidisciplinary approach used to underpin decision making processes in human and environmental health sciences. Risk assessment combines risk characterization, informed by hazard identification, dose-response, and exposure assessment, with risk communication and provides critical input informing risk management decisions. While these fundamentals remain unchanged, the discipline is evolving in scope and methodology. Unlike other scientific disciplines, contemporary challenges of the risk assessment community are not strictly technical in nature, but often situated at the interface between science and regulation/ policy.

Given its inherent complexity and often specific focus, key concepts in risk assessment are frequently not comprehensively addressed in educational programs of individual disciplines such as exposure sciences, toxicology, and epidemiology. As a result, current trainees and post-graduate professionals can benefit from educational opportunities that convey both fundamental concepts of risk assessment sciences and knowledge on applying these concepts to health evaluations. The Society of Toxicology Risk Assessment Specialty Section (SOT RASS) has developed this “Risk Assessment Syllabus” as a semi-regular opportunity for members of the SOT to enhance their understanding of essential concepts and contemporary topics in the risk assessment sciences.

In this presentation on the "Basics of Exposure Assessment," participants will be provided with a basic foundation in the concepts and principles of human exposure assessment. Participants will be introduced to the various components of an exposure assessment as well as relevant key terminology. Fundamentals that will be covered include: intake, uptake, and dose; applied, potential, internal, and biologically effective dose; acute dose, average daily dose, and average lifetime dose; and dermal, oral, and respiratory dose.
