2012年-2013年温州市食品中金属污染物监测分析

Monitoring and analysis of metal pollution in foodstuff in Wenzhou city between 2012 and 2013

目的了解温州市食品中有害金属的污染情况,为制定相应控制措施提供依据。方法对全市11个监测点共1 009份样品进行铅、镉、汞、砷、铝的监测。结果温州市食品中铅、镉、汞、砷、铝的检出率分别为51.91%(231/445)、75.96%(338/445)、40.90%(182/445)、60.90%(271/445)、95.04%(536/564);与国家食品卫生标准比较,食品中铅、镉、汞、砷、铝的超标率分别为0.45%(2/445)、8.31%(37/445)、0.45%(2/445)、21.57%(96/445)、72.70%(410/564)。受铅、镉、汞、砷污染食品主要分布在鲜冻水产品、茶叶、粮食和食用菌等。油炸面制品中铝污染水平较高。结论温州市食品中金属污染的情况较普遍,部分食品存在金属超标现象,尤其是鲜冻水产品中镉、砷污染,油炸面制品中铝污染问题较为严重,应加强监管力度并尽快完善国家食品卫生标准。

Objective To investigate the situation of harmful metal in some food in Wenzhou city,and provide basis for formulating control measures. Methods A survey tested lead cadmium mercury arsenic and aluminum was performed from 2012 to2013,1009 foods were collected from 11 monitoring sites. Results The detection rates of lead,cadmium,mercury,arsenic and aluminum in food were 51. 91%（ 231 /445）,75. 96%（ 338 /445）,40. 90%（ 182 /445）,60. 90%（ 271 /445）,95. 04%（ 536/564）; Compared with the National standards of food hygiene,the exceeding rates oflead,cadmium,mercury,arsenic and aluminum in food were 0. 45%（ 2 /445）,8. 31%（ 37 /445）,0. 45%（ 2 /445）,21. 57%（ 96 /445）,72. 70%（ 410 /564）. The lead,cadmium,mercury,arsenic mainly distributed in samples of fresh and frozen aquatic products,tea,grain and edible fungi,and the aluminum in samples of deep- fried flour products were higher. Conclusion Metal contamination in food was common in the Wenzhou,some food products contained exceeding metals,especially the cadmium and arsenic contamination in fresh and frozen aquatic products and the lead contamination in deep- fried flour products. It is necessary to strengthen the supervision and improve the national food hygiene standards as soon as possible.
