Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "Many of Canada's largest rivers, in terms of discharge and drainage area, are contaminated by toxic organic chemicals. For economic-population reasons, most of the toxic organic chemical transport and fate research on large rivers has been conducted on the high discharge "rivers" which connect the Great Lakes and the St. Lawrence River which drains the lakes to the Atlantic Ocean. To a lesser extent, two of Canada's other major rivers, the Fraser flowing to the Pacific Ocean and the Mackenzie flowing to the Arctic Ocean, have also been the subject of specific toxic organic chemical transport investigations. This paper overviews some of the results obtained over the last decade as they relate to two aspects of contamination of large rivers by toxic organic chemicals: 1) forms and 2) degree, of long-range transport"--Management perspective.
