Toward this end, samples of urban runoff and sediment have been collected at 15 sites in Fort Erie, Niagara Falls, and Welland. The collected samples have been analyzed for polychlorinated biphenyls, organochlorine pesticides, polyaromatichydrocarbons, chlorinated benzenes, and trace elements. For each substance studied, frequencies of occurrence and mean event concentrations have been determined. Using such data and the calculated annual runoff volumes and sediment yields, estimates of annual loadings of toxics transported by urban runoff and sediment have been produced for the Niagara area"--Abstract, p. i. |
