Graduate Prerequisites: (SPHEH730 & SPHBS723 & SPHBS730) or consent from instructor - Suppose you need to analyze the potential risks of a proposed point source or a possible replacement chemical in a consumer product. To do this, you need to know exposures to a pollutant but you can't measure them for everyone. What do you do? Estimation of exposure is an essential skill for building a sustainable economy, evaluating regulatory compliance or permits, risk assessment, environmental epidemiology, examining environmental justice and other purposes. Students will learn how to use publicly available data and models to estimate exposure. This hands-on course develops skills in the assumptions behind and the use of equilibrium models, compartmental models and dispersion models--all widely used in the field. Sample problems include estimation of exposure from eating contaminated fish using sediment PCB concentrations, exposure to flame retardants or PFAS from biomonitoring (blood, urine) data, inhalation of air pollutants emitted by an industrial facility. This course is suitable for PhD students as well as MPH students who meet the prerequisites.
