Abstract |
During 1981, water samples were collected from ten Lake Erie and ten Lake Michigan stations. In both Lake Erie and Lake Michigan, large percentages of aluminum, iron, and manganese were associated with particulate matter. A substantial fraction of the total beryllium, cobalt, copper, lead, tin, vanadium, and zinc were associated with Lake Michigan particulate matter. In Lake Erie, a substantial fraction of the total silver, beryllium, chromium, copper, mercury, lead, tin, and vanadium were associated with the particulate fraction. For Lake Michigan and especially Lake Erie, it appears that a significant fraction of the particulates may have been resuspended sediment. |
