中文摘要： 随着中国经济快速发展，中国公路总里程和汽车保有量迅猛增长。交通污染是环境磁学研究的一个重要目标。道路污染物的总量和类型随着车辆和燃料添加物应用新材料和新技术而发生变化。快速、经济的环境磁学手段在交通污染研究中已经发挥了重要的作用。当前环境磁学研究中，有必要注重观测污染物组成成分的变化，增强对污染物迁移的动态过程的监测，区分人为和自然组分的各自贡献。为了解决上述问题，在本项目中，拟在高流量的交通干线附近进行实验性监测布点，80cm厚度的表土将被移走，并代以异地移来的未污染土壤，以排除自然背景和历史贡献等因素的影响。以磁学为主要手段，结合重金属、铂族元素、多环芳烃等指标，在3到4年的时间里密集监测污染的空间范围、污染物组合变化和动态积累。本研究试图探索出用于交通污染监测的实用工作方法，以促进环境磁学在土壤污染研究中的应用，为环境保护提供基础资料。

英文摘要： As fast development of China economy, the total mileage of highroad and number of vehicles are increasing dramatically. The traffic pollution is one of important targets for environmental magnetism. The amount and type of pollutants along roadsides change due to the use of new materials and techniques for cars and fuel additives. The fast and economical environmental magnetic method plays an important role in traffic pollution study. In the current magnetic study, the attantion should be paid to the changes of constituent of pollutants. Moreover, Monitorring of migration of pollutants and isolation of anthropegenic and natural contribution should be strenthened. For solving the problems mentioned above, It is suggested to prepare experimental monitoring site located close to arteries with high traffic density and observe accumulation and migration of pollutants over 3 to 4 years. A 80 cm layer of top soil will be removed and replaced by non-polluted soil moved from the other place, thus excluding natural background and historical contributions. Magnetic proxies will be mainly used in this study combining with heavy metals, polycyclic aromatic hydrocarbons and platinum group elements. Formulation of guidelines for monitoring purposes will be a further practical aim of the study. Meanwhile, the results from propos
