| 摘 要： | 对杭州市郊4个主要蔬菜基地的土壤中的重金属铅、锌、铜含量进行测定分析,利用不同的评价方法和标准来评价杭州市郊蔬菜地土壤重金属的环境质量状况。结果发现如以自然背景值为评价标准,则蔬菜基地土壤中的重金属超过污染指标,污染程度为Pb > Cu > Zn;如以国家《土壤重金属污染评价标准》为评价标准,则蔬菜基地土壤中的重金属未超过污染指标,污染程度为Zn > Cu > Pb;在4个调查区中,拱墅区土壤重金属大于其它3个区。 |

| Abstract: | Contents of heavy metals (Zn, Pb and Cu) in soils from four main areas of vegetable plantation in Hangzhou city suburb were investigated in order to evaluate environmental quality of heavy Metals. Different evaluation methods and evaluation standards of heavy metals were used for comparison. The results showed that the soils were polluted with heavy metals Zn ,Pb and Cu by using natural background values as evaluation standard; While using National Standard(GB 15618-1995)as evaluation standard, soils were not polluted with heavy metals Zn ,Pb and Cu. Of four investigated areas, Contents of heavy metals in Gongshu district of the city were the highest. |
| Keywords: | heavy metal Pb Zn Cu soil vegetable environmental quality evaluation |
