Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "This is an invited feature article to be published in the journal, Environment. The report provides a review of the sources, distribution and fate of trace elements in various environmental compartments. Present-day emissions of metals into the biosphere by mining and industrial activities exceed the mobilization by natural weathering processes by several orders of magnitude for such metals as lead, copper, mercury, cadmium, chromium and zinc. The conclusion is reached that the contamination of our environment with toxic metals has become a global phenomenon and that the current levels of metal pollution may be harmful to the most sensitive organisms in some ecosystems. The human perturbation of the regional and global trace metal cycles is highlighted and concern is expressed about the growing trace metal pollution in the developing countries"--Executive summary.
