城市表層土壤論文：泉州市城市表層土壤重金屬污染評價研究-全文預覽
【正文】 最主要的生態(tài)風險貢獻因子,12種重金屬元素的生態(tài)危害等級排序為:Hg Cd Cu PbNiAsZn CoCrVMnTi。泉州市城市土壤環(huán)境質(zhì)量為Ⅲ級,達到了比較高的污染等級。因子分析結(jié)果表明,重金屬Sb、Bi、Sn、Pb、Cu、Zn主要來自交通污染和工業(yè)污染, Cd則來自工業(yè)污染和化肥施用。 Mn, Sb, Sn, Cd, Pb, Zn, Cu, Hg, Ni wre much higher than their background values of the local soil environment.(2) Based on the background values of local soil, the heavy metal pollution in the urban topsoil of Quanzhou city was estimated using the Geoaccumulation Index and Potential Ecological Risk Index. The results showed that Sb and Hg were much higher dangerous than other pollutants. The Geoaccumulation Index order of different heavy metals was HgSbNiSnCoZnPbLiCdBiMnCrAsFeVCuScTi。 Fe, Co, Ni, Cr, Li, Sc and Mn were mainly controlled by natural factors, and they originated from natural sources.【關鍵詞】城市表層土壤 重金屬污染 環(huán)境質(zhì)量評價 泉州市【英文關鍵詞】urban topsoil heavy metal pollution environmental quality assessment Quanzhou City【目錄】泉州市城市表層土壤重金屬污染評價研究摘要45ABSTRACT56第一章 緒論1119 研究背景及意義1112 國內(nèi)外研究現(xiàn)狀1215 研究內(nèi)容、方法與技術(shù)路線1517 研究目標15 研究內(nèi)容1516 研究方法及技術(shù)路線1617參考文獻17
