DISTRIBUTION AND TRANSPORT OF HEAVY-METALS IN THE SEDIMENTS OF A SMALL NORTHERN EUTROPHIC LAKE

Despite the fact that heavy metal transport is an important aspect of waste disposal schemes and aquatic resource utilization, there is little information on the long term fate of these pollutants in small enclosed ecosystems. This paper reports on a study to measure the concentrations of heavy metals in the sediments of a small, eutrophic lake, which received waste discharges from a gold mine between 1941 and 1949. The data were then used to measure relative rates of movement which were in turn correlated with variations in environmental conditions. Refs.
