采用电感耦合等离子体质谱仪( ICP-MS)法测定了浙江省10个县(市、区)香菇中Cu,Fe,Zn,Cr,Ni, Se和Mn等7种微量元素的含量,并进行统计分析,7种元素含量均符合正态或对数正态分布。其背景值分别是Zn 8.6029 mg· kg-1, Fe 5.3845 mg· kg-1, Mn 2.2159 mg· kg-1, Cu 1.0912 mg· kg-1, Se 0.0473 mg· kg-1, Cr 0.0056 mg· kg-1,Ni 0 mg· kg-1。结果表明:7种微量元素含量存在区域差异和总体正相关性;与一般蔬菜相比,Zn含量是其3~5倍,Cu含量是其1~2倍,Mn和Se含量相当;Ni和Cr的含量远低于国家食品安全标准。
採用電感耦閤等離子體質譜儀( ICP-MS)法測定瞭浙江省10箇縣(市、區)香菇中Cu,Fe,Zn,Cr,Ni, Se和Mn等7種微量元素的含量,併進行統計分析,7種元素含量均符閤正態或對數正態分佈。其揹景值分彆是Zn 8.6029 mg· kg-1, Fe 5.3845 mg· kg-1, Mn 2.2159 mg· kg-1, Cu 1.0912 mg· kg-1, Se 0.0473 mg· kg-1, Cr 0.0056 mg· kg-1,Ni 0 mg· kg-1。結果錶明:7種微量元素含量存在區域差異和總體正相關性;與一般蔬菜相比,Zn含量是其3~5倍,Cu含量是其1~2倍,Mn和Se含量相噹;Ni和Cr的含量遠低于國傢食品安全標準。

The content of 7 kinds of trace elements , Cu, Fe, Zn, Cr, Ni, Se and Mn, were determined by ICP-MS in 10 counties (cities, districts) of Zhejiang province.The statistical analysis showed that the content of 7 kinds of elements fitted normal or lognormal distribution .The background values were 8.6029 mg· kg-1 for Zn, 5.3845 mg· kg-1 for Fe, 2.2159 mg· kg -1 for Mn, 1.0912 mg· kg -1 for Cu, 0.0473 mg· kg-1 for Se, 0.0056 mg· kg-1 for Cr and 0 mg· kg-1 for Ni.It showed regional differences and overall positive correlation among the content of 7 trace elements.Compared with the ordinary vegetables , the content of Zn was 3-5 times higher, the content of Cu was 1-2 times higher , and Mn and Se content were similar .The contents of Ni and Cr were far lower than the national food safety standards .
