摘要：

Concentrations of iron, copper, zinc, cadmium, and lead were determined in samples of sediment, mussel (Perna viridis), and rock oyster (Saccostrea cucullata) from nine locations in Tolo Harbour, Hong Kong. The concentrations of metals in bivalves did not vary greatly from one location to another and showed no correlation with the concentrations in sediments. The metal concentrations in bivalves are similar to published results in the same area, and concentrations of cadmium and lead are within the local legislative limits for seafoods. Comparison of metal concentrations in bivalves in March and May 1986 shows that lower concentrations of iron, copper, and cadmium in P. viridis occurred in May, suggesting seasonal variation of trace metal concentrations in mussels. This reduction was not evident in S. cucullata. © 1990.
