Abstract
Soil samples from 5 metropolitan areas including Baltimore, Maryland; Gadsden, Alabama; Hartford, Connecticut; Macon, Georgia; and Newport News, Virginia were analyzed for elemental As, organochlorine pesticides and polychlorinated biphenyls (PCB). A representative number of samples were analyzed for organophosphorus pesticides, but none was detected. All areas exhibited heavy soil concentrations of organochlorine pesticides including .SIGMA.DDT, aldrin, dieldrin, photodieldrin, chlordane, heptachlor, heptachlor epoxide, endrin, endrin ketone and endosulfan sulfate. PCB were detected in 3 of the 5 metropolitan areas. Within the metropolitan areas, samples from the urban, or core city, locations generally had higher pesticide concentrations than did samples from suburban locations. Pesticide residue concentrations were generally higher in soils of metropolitan areas than in nearby agricultural soils.
