摘　　要：为筛选抗重金属污染能力强的双孢蘑菇(Agaricus bisporus)菌种,为消费者提供安全可靠的双孢蘑菇产品,参照食品安全国家标准GB 5009. 12—2010、GB 5009. 123—2014、GB 5009. 11—2014、GB 5009. 17—2014、GB 5009. 15—2014,借助原子吸收分光光度计和原子荧光光度计,分别测定6个菌种的双孢蘑菇中Pb、Cr、As、Hg、Cd的含量。结果显示,供试双孢蘑菇菌种中均有样品检出Pb、Cr、As、Hg、Cd,但其含量均未超出食品安全国家标准限定值,安全风险较小,可安心食用。供试菌种中,1号和6号菌种对5种重金属的抗性最强,5号和2号菌种次之,3号和4号菌种的抗性一般。这些菌种可作为抗金属污染品种直接用于生产,也可作为育种材料用于抗性菌种选育。In order to select strains of Agaricus bisporus with strong resistance to heavy metal pollution,contents of Pb,Cr,As,Hg,Cd in 6 Agaricus bisporus strains were determined by atomic absorption spectrophotometer and atomic fluorescence photometer according to national standards of GB 5009.12-2010,GB 5009.123-2014,GB 5009.11-2014,GB 5009.17-2014,GB 5009.15-2014.It was shown that Pb,Cr,As,Hg,Cd were all detected in the samples.But,their contents did not exceed the limits of national standards for food safety.The quality and safety risk of these Agaricus bisporus strains was small,and these strains were safe to eat.Among all the 6 selected strains,strains No.1 and No.6 had the highest resistance to the above 5 heavy metals,and were followed by strains No.5 and No.2,while the resistance of strains No.3 and No.4 was general.These strains could be used directly in production as anti-metal contaminant varieties or as breeding materials.
