Spatial and temporal variability in metal bioavailability and toxicity of sediment from hamilton harbour, lake ontario

Abstract Trace metals in sediment from nearshore urban and industrialized centres of the Great Lakes are frequently at concentrations well above geological background values Total metal content in sediment, however, is a weak predictor of sediment toxicity This study examined the bioavailability of metals from Hamilton Harbour in Lake Ontario and considered variability in metal forms on a temporal basis Sediment from regions within Hamilton …
