- 摘要:采用尼梅罗综合污染指数法, 参照国家土壤环境质量标准, 对成都地区的土壤重金属综合污染进行评价.划分出土壤安全区和4个土壤污染区, 其中成都市区土壤重金属污染主要为Hg, Cd和Pb, 邛崃山东坡和龙门山为Cd, Ni, Cr, Cu和Zn, 彭州青白江为Ni, Hg和Cd.在安全区内圈定了有益元素Se, Mo, B, Mn, Fe和营养元素N, P, K综合适中的都江堰、蒲江县和龙泉驿3个优质区.土壤污染区的蔬菜和人发Hg含量明显高出了安全区, 表现出了不同的生态效应.
- Abstract:This paper adopted the Nemerow Synthetical Pollution Index Method to assess the heavy metal pollution of soils in Chengdou area based on the National Environmental Quality Standard for Soils, and categorized the soils from the whole area into safe domain and 4 pollution domains. The heavy metal pollutants of Chengdu City are mainly Hg, Cd and Pb, Cd, Ni, Cr, Cu and Zn for the eastern slope of Qionglaishan and Longmenshan mountainous area, Ni, Hg and Cd for Pengzhou-Qinbaijiang domain. Dujiangyan, Pujiang County and Longquanyi are the domains with high soil quality, in which soils contained moderate levels of beneficial elements such as Se, Mo, B, Mn and Fe, and N, P and K, are determined. Hg concentrations in vegetables and human hairs of the pollution domains are generally higher than those of the safety domain reflecting different ecological effects.
