The results showed that arsenic, mercury and cadmium content could be detected in the six varieties, and all of the varieties were contaminated by heavy metals ,but they did not exceed the limits in the national standards for food safety. These varieties had a low quality risk and can be eaten safely. Varie-ties 1 and 6 were strongly resistant to the three kinds of heavy metals, while variety 4 was weakly resistant to heavy metal pollution.展开更多

The results showed that 3 heavy metal elements (lead, chromium and cadmium) were tested in the 6 varieties of A. bisporus , all of which were contaminated by heavy metals, but basically no beyond the national standards for food safety. In general, these varieties had less quality risk and could be eaten safely. The accumulation characteristics of heavy metals in these varieties were analyzed, and the varieties were screened according to the resistance to heavy metals pollution. The results showed that variety No. 1 and No. 6 were the varieties with strong comprehensive resistance to the 3 types of heavy metal pollution, and variety No. 3 was a species with weak comprehensive ability in resisting heavy metal pollution.展开更多
