On the distribution, speciation and bioavailability of heavy metals in the soils at Xiang'an, Xiamen, China

Abstract

土壤重金属化学行为与环境质量的研究是土壤圈物质循环研究的重要组成部分。随着区域社会经济的快速发展,土壤重金属的污染问题日益凸显,直接关系到土壤质量和人类生存质量。翔安区是厦门市重点农田保护区域,是厦门基础农业生产基地。本论文通过对厦门翔安区土壤重金属的分布、形态的研究,旨在全面评估翔安区土壤重金属的现状及其潜在生态效应。基于对翔安区土壤重金属全量的测定,分析了翔安区土壤重金属含量及分布特征,并与1990年全国土壤普查数据进行了比较,结果表明该区域土壤重金属含量相对于1990年,均有所增加,但其环境质量基本仍处于国家环境质量标准2级状态。根据翔安区土壤柱状样的分析,发现翔安区土壤重金属具有较强的...Heavy metals in soils have been received increasing attention due primarily to their potential environmental and ecological consequences. This is particularly true in China and issues related to soil metals have been emerging along with the rapid social and economic development during the past 30 years. Xiang’an, a district of Xiamen is a primary base of agricultural production with protected farm...学位:理学博士院系专业:海洋与环境学院环境科学与工程系_环境科学学号:2005140319
