Heavy Metals in Marine Mollusks, Crustaceans and Fish from the Shenzhen Coastal Region

Heavy metal concentrations were determined in the edible portion of mollusks, crustaceans and fish collected from Shenzhen coastal region. The concentrations (average ±standard error) of chromium, manganese, ferrum, cobalt, nickel, copper, zinc, total arsenic, selenium, molybdenum, plumbum, cadmium, tin, antimony, barium and mercury are 0.08±0.07, 3.47±2.85, 22.81±29.54, 0.04±0.02, 0.14±0.08, 0.73±0.49, 15.68±7.02, 0.73±0.41, 0.24±0.09, 0.02±0.01, 0.26±0.27, nd, 0.14±0.12, 0.01±0.01, 0.93±0.92 and 0.02±0.02 mg/kg (wet weight, ww) in muscle of fish, respectively; 0.03±0.01, 0.47±0.16, 4.48±3.92, 0.01±0.01, 0.13±0.12, 13.17±5.84, 15.45±5.30, 1.61±1.61, 0.19±0.05, 0.02±0.02, 0.03±0.03, 0.10±0.22, 0.07±0.03, nd, 0.15±0.06 and 0.01±0.01 mg/kg (ww) in muscle of shrimps, respectively; 0.21±0.07, 6.60±2.36, 89.38±40.26, 0.09±0.04, 0.83±0.44, 272.38±219.88, 623.54±446.87, 1.85±1.02, 0.43±0.06, 0.28±0.25, 0.57±0.07, 1.38±0.74, 0.33±0.07, 0.01±0, 053±0.30 and 0.01±0.01 mg/kg (ww) in edible tissue of oyster, respectively. The high values of heavy metal contamination in marine organisms obtained here are generally lower than those found in the most industrialized areas all over world. Comparing data obtained here with limits for the deleterious matters in the aquatic product from China and abroad authority, fish and crustaceans from the present coastal region, in general, are safe for human consumption, while higher concentrations of copper, the marginally higher concentrations of total arsenic and plumbum exceeding above limits in oysters should be paid enough attention.
