摘　　要：[目的]全面了解西南地区松茸中重金属(铅、镉、砷和汞)的含量,为制定松茸中重金属污染状况的评价和预警提供基础数据。[方法]收集750个松茸样品,按照GB5009系列食品安全国家标准进行相应重金属的测定,根据GB2762—2017《食品安全国家标准食品中污染物限量》进行评价。[结果]铅、镉和汞的含量97%以上符合GB2762—2017中规定食品中污染物限量要求,而总砷含量不足50%符合GB2762—2017中规定食品中污染物限量要求。[结论]此次调查选取的松茸样品中总砷含量合格率不足50%,但以无对人体危害大的无机砷含量计算均合格,因此建议食品安全国家标准中专门设定松茸中无机砷的限量,而不是总砷的限量。[Objective]To master the contents of heavy metals (lead, cadmium, arsenic and mercury) in Tricholoma matsutake in Southwest China and provide a reliable basis data for the evaluation and early warning of arsenic pollution.[Method]750 samples of Tricholoma matsutake were collected, and the heavy metals were determined according to GB 5009 series of national food safety standards, and evaluated according to GB 2762-2017 National Food Safety Standard Food Pollutants Limit.[Result]More than 97% of the contents of lead, cadmium and mercury met the requirement of food contamination limits stipulated in GB 2762-2017, while less than 50% of the total arsenic content met the requirement of food contamination limits stipulated in GB 2762-2017.[Conclusion]The qualified rate of total arsenic content in Tricholoma matsutake samples selected in this survey is less than 50%, but the calculation of organic arsenic content which is not harmful to human body is qualified. Therefore, it is suggested that the limit of inorganic arsenic in Tricholoma matsutake should be set in the national food safety standards, rather than the total arsenic limit.
