Abstract: 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.

Key words: Agaricus bisporus, heavy metal accumulation, heavy metal pollution, variety breeding
