To investigate heavy metals contamination level in food in Shaoxing, and to provide basis evidence for supervising heavy metals pollution in food and environmental pollution control in Shaoxing.
Food samples in 2014 were detected for lead, cadmium, mercury, arsenic, nickel, copper and chromium by national standard methods, and the results were evaluated by GB 2762-2012 Pollutants limits in food.
1384 samples from 10 food categories were collected and tested for lead, cadmium, mercury and arsenic, the over standard rates were 2.0%, 3.0%, 1.5% and 0.22%, respectively, the median were 0.019, 0.0085, 0.0024 and 0.015 mg/kg, respectively; 273 samples were collected and tested for nickel, the detection rate was 48.4%, the median was 0.010 mg/kg; 255 samples were collected and tested for chromium, the detection rate was 14.9%, the median was 0.0050 mg/kg; 486 samples were collected and tested for copper, the detection rate was 94.0%, the median was 1.34 mg/kg. The heavy metals over standard rate of aquatic products, animal internal organs and grain were relatively high, 16.9%, 7.9% and 7.3% cadmium in swimming crabs exceeded standard seriously, the over standard rate was 38.9%.
The overall pollution of heavy metals in food are not high in Shaoxing in 2014, but some food (aquatic products, animal internal organs and grain) pollution are relatively outstanding, and have the over standard problems of lead, cadmium, mercury and arsenic.
调查绍兴市食品中重金属污染水平，为绍兴市食品重金属污染监管及环境污染治理提供依据。
采用国家标准方法对2014年食品样品中的铅、镉、汞、砷、镍、铜和铬进行检测，并依据GB 2762-2012《食品中污染物限量》对结果进行评价。
采集10类食品共1384份样品检测铅、镉、汞和砷，超标率分别为2.0%、3.0%、1.5%和0.22%，中位数分别为0.019、0.0085、0.0024和0.015mg/kg；采集273份样品检测镍，检出率为48.4%，中位数为0.010mg/kg；采集255份样品检测铬，检出率为14.9%，中位数为0.0050mg/kg；采集486份样品检测铜，检出率为94.0%，中位数为1.34mg/kg。水产品、动物内脏和粮食的重金属超标率相对较高，梭子蟹镉超标严重，超标率为38.9%。
2014年绍兴市食品重金属总体污染程度不高，但部分食品（水产品、动物内脏和粮食）污染较为突出，存在铅、镉、汞和砷超标问题。
