摘　　要：笔者采用电感耦合等离子发射光谱仪和原子荧光分光光度计对山西省8个县80份核桃基地土壤样品中的Cd、Pb、Cu、Cr、Hg、As 6种重金属元素含量进行了检测,并依据NY/T 1054-2021《绿色食品产地环境调查、监测与评价规范》进行了土壤重金属污染评价。结果表明,山西各核桃基地土壤中6种重金属元素含量的差异较大,但Cd、Pb、Cu、Cr、Hg、As的单项污染指数均<1,总体处于安全水平。孝义市的综合污染指数处于警戒水平,等级为尚清洁,但Cd含量存在潜在的污染风险,其他核桃产地的综合污染指数等级均为清洁。The contents of 6 heavy metal elements Cd, Pb, Cu, Cr, Hg and As in 80 soil samples from walnut bases in 8 counties of Shanxi Province were determined by inductively coupled plasma and atomic fluorescence spectrometry. The soil heavy metal pollution assessment was carried out according to NY/T 1054-2021《Environmental investigation, monitoring and evaluation criterion of green food producing area》. The results showed that the contents of 6 heavy metal elements in the soil of each walnut base in Shanxi vary greatly, but the single pollution indexes of Cd, Pb, Cu, Cr, Hg, As were less than 1, which were generally at a safe level. The comprehensive pollution index of Xiaoyi City was at the alert level and the level was still clean, but the Cd content had potential pollution risks. The comprehensive pollution index of other walunt bases was clean.
