N2 - Green-lipped mussels, Perna viridis, were collected from Kat O, Yim Tin Tsai, Ma Liu Shui and Tap Mun around Tolo Harbour and six local markets in Hong Kong (Aberdeen, Shau Kei Wan, Kowloon City, Mongkok, Yuen Long) and Shenzhen (Dongmun) between July 1994 and February 1995 and analysed for cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni), lead (Pb) and zinc (Zn). The metal concentrations of mussels collected from the study sites were Cd (0.45-1.44 μg/g), Cr (0.82-4.89 μg/g), Cu (6.02-23.99 μg/g), Ni (3.25-6.87 μg/g), Pb (2.02-4.36 μg/g) and Zn (90-135 μg/g), while those from the markets were Cd (0.27-1.44 μg/g), Cr (1.09-3.30 μg/g), Cu (9.05-17.8 μg/g), Ni (2.44-5.25 μg/g), Pb (1.17-5 μg/g) and Zn (51-103 μg/g). The metal concentrations were below the maximum permissible levels set by the Hong Kong Government. In addition, seasonal variation of metal accumulation in mussels was investigated in Yim Tin Tsai and Ma Liu Shui and a reduction in the total heavy metal concentrations during winter was noted. The non-carcinogenic hazard index of mussels collected from Tolo Harbour and from Hong Kong markets was between 0.46 and 1.36 compared with those from Shenzhen markets (0.85-1.46), which indicated a low but possible risk in consuming the mussels.
