摘要

The University of Minnesota Rosemount Research Center is a National Priorities List site consisting of six areas located in Dakota County, Minnesota. Different areas of the soil are contaminated with methylene chloride, 1,2-dichloroethane, 1,1,1-trichloroethane, carbon tetrachloride, trichloroethene, polycyclic aromatic hydrocarbons, polychlorinated biphenyls, chlordane, heavy metals, 2,3,7,8-tetrachlorodibenzo-p-dioxin, toluene, lindane, and 2,3,7,8-tetrachlorodibenzofuran. On-site and off-site groundwater is contaminated with concentrations of chloroform, TCA, CT, DCA, heavy metals, toluene, xylene, and nitrates. Food chain contamination is a possibility. The site is of potential health concern because of the risk to human health resulting from possible exposure to hazardous substances at concentrations that may result in adverse health effects. Human exposure to heavy metals, PCBs, TCDD, TCDF, and nitrates-nitrogen may occur, may be occurring, and may have occurred via ingestion, inhalation, and dermal absorption.
