【中文摘要】 測定雙孢蘑菇、巴西蘑菇、茶樹菇、黑木耳、雞腿菇、金針菇、香菇、金頂側耳、杏鮑菇、平菇、銀耳11種食用菌的175個干樣品中的砷(As)、鎘(Cd)、汞(Hg)、鉛(Pb)的含量。結果表明,11種食用菌干品中,砷含量范圍為0.02mg·kg-1～0.78mg·kg-1;鎘含量范圍為0.02mg·kg-1～1.949mg·kg-1;汞含量范圍為未檢出～0.654mg·kg-1;鉛含量范圍為0.040mg·kg-1～3.217mg·kg-1。我國栽培食用菌中鎘、汞、鉛含量比較安全,雙孢蘑菇中汞含量高與黑木耳中鉛含量高具有地域特性。
【英文摘要】 175 dry samples of 11 kinds of cultivated edible fungi, i.e. Agaricus bisporus, Agaricus blaze, Agrocybe cylindracea, Auricularia auricular, Coprinus comatus, Flammulina velutipes, Lentinula edodes, Pleurotus citrinopileatus, Pleurotus eryngii, Pleurotus spp., Tremella fuciformis were collected from 31 counties. Contents of As, Cd, Hg and Pb of these samples were analyzed. It shows that contents of As were 0.02 mg·kg-10.78 mg·kg-1, and the maximum one and the minimum one were Agaricus blaze, Tremella fuciformis. Contents of Cd were 0.015 mg·kg-11.949 mg·kg-1, the maximum one and the minimum one were Agaricus blaze, Agrocybe cylindracea. Contents of Hg were 00.654 mg·kg-1, the maximum one and the minimum one were Agaricus blaze, Tremella fuciformis. Contents of Pb were 0.040 mg·kg-13.217 mg·kg-1, the maximum one and the minimum one were Auricularia auricular, Pleurotus citrinopileatus. Contents of As, Cd, Hg, Pb in cultivated edible fungi were safe, while high contents of Hg in Agar...更多icus bisporus and Pb in Auricularia auricular related to the locations where samples grew. 還原
