石家庄裕华路西段道路尘与表土重金属污染

城市道路尘与土壤表土是现代化城市环境变化的重要载体，记载了城市工业、交通和人类活动的环境影响。在城市化不断加快的背景下，重金属污染对人体潜在的危害越来越大，重金属污染监测已日益引起人们高度重视。磁化率在一定的环境中可作为重金属的替代指标，磁性测量成为城市环境污染监测的新途径新方法。通过对石家庄裕华路西段道路尘土与土壤表土样品的低频磁化率分析得出结论：裕华路西段道路尘磁化率自市中心向郊区逐渐降低，道路尘重金污染程度由市中心向郊区逐渐减弱；不同区位的道路尘与土壤表土重金属污染程度分别为中心区〉二环以内〉三环以内〉郊区和三环以内〉二环以内〉郊区〉市中心；同一区域的道路尘比土壤表土的重金属污染更严重。

The Heavy Metal Pollution of Urben Street Dust and Surface Soil in the West Part of the Yu Hua Street of Shijia Zhuang

Heavy metal is a kind of potential pollution,as the city develop faster,the morn heavy metal accumulate the morn harm it will do to human healthy.magnetic susceptibility can be used as a proxy parameter for heavy metals,magnetic measure has become a new method for monitoring the pollution of urban environment.In this study,first,we get the susceptibility by magnetic measure of the street dust and surface soil from each test site in the west part of YUHUA Street in SHIJIAZHUANG;then,analysis the extent of th...
