云南省部分地区食用菌重金属含量的分析及评价

Analysis and Assessment of Heavy Metal Pollution in Fresh Edible Mushrooms Collected from Several Aereas in Yunnan Province

对云南文山和保山市售13种鲜食用菌样品中的铅、镉、砷、汞、铜的含量进行了检测,并结合国家卫生质量标准(GB 7096-2003)及《绿色食品-食用菌》NY/T 749-2003,对被测食用菌中的重金属含量进行安全评价。结果表明:产自文山和昆明的被检食用菌样品中As、Cd、Pd的含量严重超出国家卫生限量标准,产自保山的食用菌重金属Cd含量严重超标,As、Pd在部分样品中也超标。该研究对云南省食用菌生产市场安全性质量控制提出了警示。

The content of 5 heavy metals（As, Hg, Cd, Pd, Cu）in 13 kinds of edible mushrooms, collected from Wenshan and Baoshan markets were detected respectively. Safety assessment was done in reference to the nationl health quality standards（GB 7096-2003）and green food-edible mushrooms（NY/T 749-2003）. The results showed that Cd, As and Pd concentrations in mushrooms produced in Wenshan and Kunming and Cd concentrations produced in Baoshan exceeded the national standard of China badly. Pd and As concentration in partial samples collected from Baoshan overrun the regulated criteria. The results put forward warning to safety control of mushroom production in Yunnan province.
