| 摘 要： | 对覆盖宝安区的20个主要荔枝、龙眼生产基地土壤进行重金属污染调查,选取锌(Zn)、铜(Cu)、铬(Cr)、铅(Pb)、汞(Hg)、镉(Cd)和砷(As)7个指标,采用单项污染指数法和综合污染指数法对其土壤环境质量进行了评价.结果表明,20个样点土壤中19个样点土壤没有受到污染,1个样点受到轻度污染,污染率为5%.2级土壤和3级土壤主要是由于汞(Hg)污染造成的.

| Abstract: | Soil samples that were collected from 20 major lichee and longan production bases in Bao'An district,Shenzhen city were investigated for the assessment of heavy metals pollution of these soils by means of single pollution index method and comprehensive pollution index method based on 7 pollution indexes(Zn,Cu,Cr,Pb,Cd,As,Hg),respectively.The results showed that 19 of the 20 soil samples were not polluted,and only 1 soil samples had been polluted and the pollution rate was 5%.The environmental quality for grade 2 and grade 3 soils were mainly polluted by Hg. |
