项目摘要

The amount and type of pollutants along roadsides change due to the use of new materials and techniques for cars and fuel additives. In the past polycyclic aromatic hydrocarbons and heavy metals (Pb, Zn, Cd, Cr) have been accumulated near roads. Since withdrawal of leaded petrol the importance of Pb decreased, whereas due to catalytic converters platinum group elements now play an increased role. Soil samples reveal the accumulated amount of pollutants. In this project we intend to assess the present characteristics of roadside pollution. It is suggested to prepare experimental monitoring plots located close to arteries with high traffic density and observe accumulation over two to three years. A 15 cm layer of top soil will be removed and replaced by clean quartz sand thus excluding natural background and historical contributions. Verification of the origin of pollutant particles will be carried out on the basis of their characteristic morphology, magnetic and chemical properties. Together with pollutants iron phases are emitted and deposited on the ground, also having adsorption capacity for heavy metals. This allows us to use magnetic proxy methods for fast and efficient assessment of the spatial extent and qualitative degree of contamination. Climatic and socio-economical factors can influence the characteristics of roadside pollution. Therefore monitoring plots will be established in different climatic conditions. Formulation of guidelines for monitoring purposes will be a further practical aim of the study. The work will be done as a German-Polish collaboration project including partners from several other countries.

由于使用新材料和燃料添加剂的新材料和技术，沿路边的污染物的数量和类型发生了变化。过去，多环芳烃和重金属（PB，Zn，CD，CR）在道路附近积累了。自从脱离铅汽油以来，PB的重要性下降了，而由于催化转化器引起的铂类组元素现在起着更大的作用。土壤样品揭示了污染物的累积量。在这个项目中，我们打算评估路边污染的当前特征。建议准备靠近交通密度高的动脉的实验监测地块，并观察到两到三年的积累。 15厘米的顶部土壤将被清除并用干净的石英砂代替，因此不包括自然背景和历史贡献。验证污染物颗粒的起源将根据其特征形态，磁性和化学特性进行。与污染物的铁相发射并沉积在地面上，还具有重金属的吸附能力。这使我们可以使用磁代理方法快速有效地评估空间范围和质量污染程度。气候和社会经济因素会影响路边污染的特征。因此，将在不同的气候条件下建立监视图。为监测目的的指南制定将是研究的进一步实践目的。这项工作将作为一个德国合作项目完成，其中包括来自其他几个国家的合作伙伴。
