目的:了解闽北地区农产品中重金属铅、镉、汞的含量水平,分析污染原因,评价其食用安全性。方法:结合省下达的食品污染物监测任务,采集闽北地区十个县市大型超级市场和农贸市场所出售的农产品,共检测12个种类462份样品,测定重金属铅、镉、汞的含量。结果:2010年-2011年我区12种农产品中铅、镉、汞的总体合格率分别达到97.4%、95.6%和97.7%。肉类、无铅皮蛋、鱼类、奶制品和茶叶的总合格率均为100%;甲壳类产品的合格率最低为33.3%。结论:2010年-2011年我区农产品重金属污染状况总体不严重,但流通市场中的干食用菌、甲壳类产品重金属超标严重,应采取相应措施,改善近海水质污染,加强养殖业、种植业的监督管理,确保农产品的质量安全。
Objective: To understand the contents of Pb, Cd and Hg in agricultural products in northern Fujian, analyze the causes of pollution and evaluate their safety. Methods: In combination with the task of monitoring food contamination, the agricultural products sold in the large supermarkets and farmers’ markets in ten counties of northern Fujian were collected. A total of 462 samples of 12 species were collected for the determination of lead, cadmium and mercury in heavy metals. Results: From 2010 to 2011, the overall pass rates of lead, cadmium and mercury in 12 kinds of agricultural products in our district reached 97.4%, 95.6% and 97.7% respectively. Meat, unleaded preserved eggs, fish, dairy products and tea with a total pass rate of 100%; crustaceans product pass rate as low as 33.3%. Conclusion: The heavy metal pollution of agricultural products in our region from 2010 to 2011 is generally not serious, but the heavy metals in dried edible mushrooms and crustaceans in the circulation market exceed the standard seriously. Corresponding measures should be taken to improve the pollution of coastal water and enhance the quality of aquaculture and planting industries Supervision and management to ensure the quality and safety of agricultural products.
