2002年我国水产食品中镉含量监测及分析

Survey on the cadmium levels in fish, crustaceans and bivalve mollusks in China of 2002

目的 了解我国水产品中镉污染状况。方法 2 0 0 2年全国污染物监测网对我国十个省市 1 4个监测点进行 1 390个水产品中镉含量监测。结果 我国水产品中镉的平均含量为 0 0 6～ 0 5 3mg kg ,我国水产品的镉污染全国平均水平并不严重 ,淡水鱼、海水鱼、软体贝类、甲壳类等水产品全国平均值符合我国的国家标准。但部分地区镉污染严重 ,平均污染水平超过国家标准 ,最高镉含量超过 8mg kg。

A survey on the cadmium content of fresh water, marine fish bivalve mollusks and crustaceans in China was carried out by the National Institute of Nutrition and Food Safety, Chinese Center for Disease Control and Prevention in 2002. The fish from fresh water( n =193),marine ( n =367) ,crustaceans ( n =318)and bivalve mollusks( n =512)were collected from 14 provinces and cities and analyzed by AAS. It was found that the samples with mean concentration between 0 06 0 53 mg/kg. However, some of samples were up to 8 mg/kg, indicating that the cadmium content of some fishes exceeded the maximum level of national standards.
