Human Health Effects Study of a Spill of Aromatic Distillates in Superior,Wisconsin

摘要

In 1992, a spill of aromatic distillates resulted in the evacuation of more than40,000 people from Douglas County, Wisconsin. In 1995, a retrospective cohort study was conducted to determine if the spill had caused significant health effects. A total of 1,126 households were surveyed by telephone over a 2-month period to obtain information relevant to exposure to the spill chemicals, health status, and potential confounders for both the respondents and for a roster of household members. The estimates of exposure included perceived odor, distance from the spill, and household exposure as predicted by a deterministic model of the chemical plume. Objective measures of exposure to the spill were not associated with any major health effects 3 years after the spill.
