    摘要:

    了解绍兴地区蔬菜中铅、镉和总汞的含量水平及污染程度,为制定蔬菜中重金属污染控制措施提供依据。方法 2007—2014年在绍兴地区7个调查点的农贸市场、超市等地点随机抽取7类共984份蔬菜样品,采用国家标准方法检测蔬菜中铅、镉和总汞的含量,按GB 2762—2012《食品中污染物限量》统计超标情况。采用单因子污染指数和内梅罗综合污染指数评价蔬菜中重金属污染程度。结果 984份蔬菜样品铅、镉和总汞的检出率分别为68.4%(673/984)、92.0%(905/984)和37.6%(370/984),超标率分别为2.9%(29/984)、1.2%(12/984)和5.8%(57/984),平均值分别为0.040、0.017和0.004 0 mg/kg;2009—2011年蔬菜中总汞超标率较高,超标率分别为17.3%(19/110)、24.7%(19/77)和10.1%(12/119);鳞茎类蔬菜中铅和镉超标率分别为14.0%(6/43)和11.6%(5/43),均为各类蔬菜中最高。所有种类蔬菜的综合污染指数均小于0.7。结论 绍兴地区蔬菜中重金属总体污染水平不高,但部分蔬菜中重金属污染相对较突出,应继续加强监管和控制。

    Abstract:

    To investigate lead, cadmium and total mercury contamination in vegetables in Shaoxing, provide basic evidence for formulating the control measures.Methods During 2007 to 2014,4 vegetable samples were collected from farmers′ markets and supermarkets in seven monitoring sites in Shaoxing, all the samples were analyzed for lead, cadmium and total mercury by national standard methods, and the results were evaluated by GB 2762-2012.The contamination of heavy metals in vegetables was evaluated by single factor contaminant index and Nemero comprehensive contaminant index. Results The detection rate of lead, cadmium and total mercury were 68.4%(673/984),92.0%(905/984)and 37.6%(370/984) respectively, the violation rates were 2.9% (29/984), 1.2% (12/984) and 5.8% (57/984) respectively, and the mean values were 0.040,0.017 and 0.0040 mg/kg respectively. The violation rates of total mercury from 2009 to 2011 were higher than other years,which were 17.3%(19/110), 24.7% (19/77) and 10.1% (12/119)respectively. The violation rates of lead and cadmium in bulbous vegetables were 14.0% (6/43)and 11.6% (5/43) respectively, which were the highest in all kinds of vegetables. The comprehensive contaminant index of all kinds of vegetables was less than 0.7. Conclusion The overall contamination of heavy metals in vegetables was not high in Shaoxing, but should be concerned in some kinds of vegetables, and control measures should be strengthened.
