Abstract
Objective:To detect the mass fraction of As,Cd,Hg in Lentius edodes and Pleurotus ostreatus,analyze the exposure dose of those heavy metal in crowd and give an assessment of environmental and human health risk on the results of experiments.Method:The concentration of As, Cd,Hg were detected by atomic absorption spectrum and atomic fluorescence.Result:The heavy metal concentrations were(0.152±0.08)mg/kg for As,(0.308±0.07)mg/kg for Cd and(0.112±0.05)mg/kg for Hg in Lentius edodes;(0.48±0.08)mg/kg for As,(0.306±0.06)mg/kg for Cd and(0.113±0.08)mg/kg for Hg in Pleurotus ostreatus.According to the result,for the residents in our city,the average exposure of As,Cd,Hg from Lentius edodes were 0.96μg/kg,0.46μg/kg,1.59μg/kg,from Pleurotus ostreatus were 0.98μg/kg,0.48μg/kg,1.62μg/kg.There were statistically significant between city residents’ heavy metals exposure levels and national executive ADI value in mushroom,dried mushroom(P<0.01). Conclusion:The concentration of As,Cd,Hg from Lentius edodes and Pleurotus ostreatus do not excert any negative effects on the health of the residents in our city.关键词
