5203 |a"Surface runoff has been long recognized as a significant source of contaminants pertinent to land use activities and other local environmental conditions. The level of runoff pollution is particularly significant in the case of highways, where operation of motor vehicles, and wear and maintenance of highway structures produce such toxic contaminants as heavy metals and hydrocarbons (particularly polycyclic aromatic hydrocarbons, PAHs). The report that follows provides characterization of highway bridge runoff (average daily traffic 92 000 vehicles) with respect to selected heavy metals and PAHs, and thereby attempts to fill a void in the Canadian environmental literature. The data presented should be of interest to water managers and environmental planners dealing with receiving waters impacted by highway or road runoff, and environmental scientists interested in sources and pathways of heavy metals and PAHs, and their effects receiving waters"--Management perspective.
