Contaminant Dispersion and Exposure at Northeast Cape: 

Contaminant Dispersion and Exposure at Northeast Cape Dispersion and partitioning of contaminants from the Northeast Cape site has resulted in contamination of environmental media. Mirex, a banned pesticide and flame retardant, and PCBs increase upwards in sediment cores indicating erosion of a primary on-site source. Dust from the site and uptake from contaminated soils effect plants used for food and medicine. Preferential partitioning of the lower chlorinated congeners via volatilization and solubilization alters the chemical fingerprint of the technical mixtures (Aroclors) used. The high PCB chlorination in air and water argue against long-distance atmospheric transport of the contaminants. Sediment cores from the Northeast Cape Main Complex and Suqi Estuary nearly a mile away have polychlorinated biphenyl (PCB) concentrations equal to impacted and rural areas in North America. Air sampling indicates concentrations similar to those from highly impacted, industrial sites elsewhere. This supports a local, rather than long-distance, source for PCBs. Site characterization, background concentrations, and the recommended use of congener-specific PCB analyses are contentious issues.
