| 520 | |a"The increase of mercury concentrations in surface sediments from Lake Huron to Lake St. Clair and Western Basin of Lake Erie was attributed to industrial mercury inputs in 1970's. This study was carried out to investigate the present distribution pattern of mercury in Lake St. Clair sediments, and the concentration and association of mercury in the sediments from the St. Clair River. The results of the study showed a decrease of mercury concentrations in the surficial sediment of Lake St. Clair from 1974, despite continuous input of mercury into the lake. The concentration of mercury was greater in the nearshore sediments of the St. Clair River at Sarnia than that in the Lake St. Clair sediments. The results indicated a different association of mercury in the sediments of the St. Clair River and Great Lakes depositional basins. This investigation was carried out under study no.
