摘要:
以苏南河网地区常熟青墩塘河岸带土壤为研究对象,在系统调查河岸带土壤环境中重金属含量的基础上,采用单因子污染指数与模糊数学综合评价相结合的方法,分别对河岸带土壤重金属污染进行了分析与评价.结果表明,土壤中重金属As、Pb、Cr、Cd、Zn、Cu、Ni、Hg的含量分别为39.72 mg/kg～210.16 mg/kg、2.23 mg/kg～9.56mg/kg、94.88 mg/kg～64.08 mg/kg、0 mg/kg～0.12 mg/kg、82.34 mg/kg～238.39 mg/kg、31.13 mg
Abstract:
Taking the riparian soils along South Jiangsu Region as research object， assessment of heavy metal contamination were carried out by single pollution index and fuzzy comprehensive assessment after the heavy metal concentrations were determinated． The results showed that the concentrations of Arsenic( As) ，Plumbum( Pb) ，Chrome( Cr) ，Cadmium ( Cd) ，Zinc( Zn) ，Cuprum( Cu) ，Nickel( Ni) and Hydrargyrum( Hg) were 39． 72 mg /kg ～ 210． 16mg /kg，2． 23 mg /kg ～ 9． 56 mg /kg， 94． 88 mg /kg ～ 64． 08 mg /kg，0 mg /kg ～ 0． 12 mg /kg， 82． 34 mg /kg ～ 238． 39 mg /kg， 31． 13 mg /kg ～ 52． 22 mg /kg， 15． 33 mg /kg ～ 30． 30 mg /kg and 0． 19 mg /kg ～ 0． 56 mg /kg respectively． Accoding to the single pollution index，Pb is in safe state，Cd and Ni is in warning level． Cr，Cu and Zn are in venially polluted level and Hg is middle， while As is seriously polluted． Fuzzy comprehensive assessment indicated that: As is the most important polluted factor at all the sampling point． Therefore，As hyperaccumulator should be considered during greening along riparian so as to simultaneously realize the greening riparian and pollution control．
