浙江省蘑菇重金属背景值及质量安全评价

摘要

在浙江省的蘑菇生产基地、超市和农贸市场对蘑菇进行实地抽样检测,并对数据进行统计分析,提出了浙江省蘑菇重金属背景值.研究结果显示浙江省鲜蘑菇重金属背景值为铅0.144 mg/kg、镉0.026 mg/kg、汞0.038mg/kg、砷0.085 mg/kg,该背景值为实地抽样检测,来源明确,样本分布具有代表性,分析方法和结果可靠.经与相关标准进行比较,表明浙江省蘑菇重金属含量处于相对较低的水平.蘑菇的重金属含量明显高于一般蔬菜,特别是砷和汞,应作为质量安全控制的重点,在生产种植中要对栽培料中的重金属含量水平进行控制.%Background value of heavy metals content in Agaricus campestris in Zhejiang province were determined by random sampling in main production areas, supermarkets and farmer's market. The result showed it was 0.144 mg/kg for Pb, 0.026 mg/kg for Cd, 0.085mg/kg for As and 0.038 mg/kg for Hg. Comparison of determinded values to related national and industrial quality standards demonstrated that the value of heavy metals content in A. eampestris in Zhejiang was safe. The content of Hg and As in A. campestris was remarkably higher than common vegetables, and should be the focus for quality controls.
