Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "Evaluation of the environmental hazards posed by toxic contaminants requires determination of the significance of specific point and non-point sources of toxic contaminants discharged into receiving waters. One of such sources, urban runoff, is addressed in this paper. Selected toxic contaminants were studied in surface runoff from 12 Ontario municipalities. The results of these studies are summarized and presented in the form of contaminant occurrences, mean levels, and calculated loading partitioning between the water and sediment. This information should be of interest in inventory studies of toxic contaminants, comparative evaluations of their sources, considerations of control measures and general water quality studies in urban areas"--Management perspective, p. i.
