Trace elements in lake sediment, macrozoobenthos, and fish near a coal ash disposal basin

Samples of lake sediment, macrozoobenthos, and fish were collected during 1983 and 1984 near a coal ash disposal basin situated on the western shoreline of Lake Erie. Neutron activation analysis was used to determine if potentially toxic trace elements were present in higher concentrations at stations near the basin than at reference stations a few kilometers away. Of the 29 trace elements examined, arsenic and cobalt were significantly (p
