摘要:

Lead, which has been identified as a constituent of automobile exhaust, was found associated with sediments in snow dump areas in Ottawa. Lead levels in these sediments were over an order of magnitude above those of uncontaminated sediments. Algae and aquatic plants exposed to these same lead contaminated sediments over a 2–4 month period were shown to have higher lead concentrations than those grown over control sediments.
