Metals Concentrations in the Sediments of Richard Lake, Sudbury Canada and Sediment Toxicity in an Amphipod Hyalella azteca

Surface sediment from 9 different water depths at 1 m depth intervals (1 to 9 m) in Richard Lake, Sudbury, Canada was sampled in August 1998 and analyzed for 10 metals including copper (Cu), zinc (Zn), cadmium (Cd), nickel (Ni), lead (Pb), cobalt (Co), molibidenum (Mo), vanadium (V), barium (Ba) and titanium (Ti). Metal analysis showed that surface sediment at the depth of 3 m depth has the highest concentrations of metals especially of Ni (4721.1Â±821.6 Î¼g g^-1) and Cu (1011.0Â±46.4 Î¼g g^-1). The results of a toxicity study in the laboratory which showed that surface sediment from a depth of 3 m was the most toxic to H. azteca (LT50 129.12 h) and had the highest metal concentrations (especially Ni and Cu) in overlying water and in amphipod tissues.
