Distribution of metals in different size fractions of sediment from the Niagara River / Alena Mudroch and George A. Duncan. : En13-5/85-70E-PDF
"This report results of the investigation of the relationship between metals and different particle size fractions in a fluvial sediment exposed to many pollutant sources. The investigation was carried out during 1984-85 under project ECD-236. Bottom of the Great Lakes connecting channels are composed mainly of coarse particles. The study showed that there is still a significant quantity of silt and clay size particles mixed with sand on the Niagara River bottom. These fine particles contained up to twenty six times higher concentration of lead, zinc, copper, chromium and cobalt than the fine particles from Lake Erie. These fine particles are susceptible to the re-suspension and from the Niagara River into Lake Ontario. Sand-size particles collected from the Niagara River bottom in the vicinity of‘a steel plant contained up to sixteen timers higher concentration of iron, chromium, cobalt and zinc than sand-size particles from Lake Erie. These be man-made particles disposed of into the Niagara River. The study showed that the information on total metal concentration of sediment is not sufficient and that some sediment particles can contribute greater metal quantities. Re-suspended fine grained particles are an important carrier of metal pollutants within the Great Lakes system"--Exec. summary.
