Results are presented of a comprehensive, multi-media, human-health risk assessment of the contamination in the Midland, Michigan, area with 2,3,7,8-tetrachlorodibenzo-p-dioxin, or TCDD, and related compounds (dioxin) resulting primarily from past releases from the Dow Chemical Company's Michigan Division plant. The risk assessment follows USEPA's published guidelines for carcinogen risk assessment and exposure assessment. An exposure-assessment section summarizes the available environmental-monitoring data for the Midland area and derives estimated human intakes of dioxin for a number of scenarios based upon exposure of the local population to ambient air, drinking water, soil, and fish. Finally, a risk-characterization section combines the dose response and exposure information to determine estimated probabilities of adverse health effects for the scenarios considered.
