| 摘 要： | 对陕西16个苹果主产县的47个果园的土壤重金属含量进行了检测分析.结果表明,Cd、Cr、Cu、Pb、Hg、As 6种重金属均有检出,但均未超过无公害苹果产地环境技术条件标准的含量限值;依据绿色苹果产地土壤环境质量标准,除1个采样点土壤的As元素单因子污染指数为1.03外,其余各采样点土壤中各项重金属元素的单因子污染指数均小于1,47个土样的加权综合指数值小于0.56,均属于清洁级.As是今后苹果园土壤重金属监测和控制的重点.

| Abstract: | The contents of soil heavy metals of apple orchards were monitored and analyzed on 47 soil samples in apple orchards of 16 counties of Shaanxi.The result of test showed that the detection rates of Cd,Cr,Cu,Pb,Hg and As were 100%,but the amounts were all below the permitted level of no-harmful apple producing environmental standard;according to the permitted level of green apple producing environmental standard,the values of the singleitem pollution index of the soil heavy metals were all smaller than 1 exce... |
