[Concentrations of heavy metals and safe assessments of fishes in main lakes from Wuhan City].

The concentrations of Zn, Cu, Pb, Cr and Cd have been measured by ICP-OES in clays, water and fishes from representative lake, including South Lake, East Lake and Yezhi Lake in Wuhan City. The results were obtained as follow: the concentration of Cu from Yezhi Lake and the concentration of Cd from East Lake are respectively 0.010mg/L and 0.0054mg/L, and higher than the standard of water quality in fresh water cultivation. The concentrations of cadmium from three lakes sediments are 0.95mg/L, 1.07mg/L and 1.13mg/L, and also higher than the surroundings requirement of environmentally harmless aquatic products. The variety of concentrations of heavy metals have been observed in different tissues and different families. Heavy metals are mainly accumulated in scales and gills. The concentrations of heavy metals of mussels are much lower than the health standard of consumptions.
