Metal contamination in sediments and biota of the Bay of Quinte, Lake Ontario, Canada

Sediment, macrophytes and snails from wetlands at Bellaville close to the Moira river (contaminated with mine effluents from 1880s to 1960s) and from Hay bay (uncontaminated with mine effluents) 20 km from the Moira river were analysed in 1987 for aluminium, arsenic, bromine, cadmium, cobalt, chlori...

Description
Summary:Sediment, macrophytes and snails from wetlands at Bellaville close to the Moira river (contaminated with mine effluents from 1880s to 1960s) and from Hay bay (uncontaminated with mine effluents) 20 km from the Moira river were analysed in 1987 for aluminium, arsenic, bromine, cadmium, cobalt, chloride, chromium, caesium, iron, hafnium, potassium, lanthanum, sodium, magnesium, scandium, rubidium, tantalum, thorium, titanium, uranium, vanadium, and zinc using neutron activation analysis (NAA) and silver, arsenic, copper, mercury, lead, and zinc using acid dissolution and atomic absorption spectrophotometry (AAS). Arsenic levels in sediments and plants were higher. Copper and nickel concentrations were higher in Hay bay than at Belleville. Species performance in bioassays differed. Cadmium and vanadium were accumulated at higher levels by Stagnicola elodes than by Planorbella trivolvis. Myriophyllum spicatum accumulated lead up to 9.6 ppm, while Vallisneria americana showed no lead levels. The use of NAA and AAS in combination was advocated to detect a wide range of contaminants in sediments and biota.
