Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "The analysis of precipitation samples from rural sites in both Canada and the United States are presented. Comparison with published data shows that our results are very likely the only reliable measurements of cadmium and thus constitute the first baseline data for North America. ... The results on the biogeochemical availability of cadmium, lead and zinc on atmospheric particulate matter substantiates our earlier suggestion (Lua et al, 1982) that toxic metal (and-phosphorus) are likely to have a significant environmental impact on aquatic systems because of their ease of solubility. We now suggest that the possible sites of greatest impact will likely be at interfaces e.g., forest canopies and at the air-water interface in lakes and rivers"--Management perspective.
