研究人员分析了在意大利巴勒莫市区收集的道路灰尘中的无机物，以确定由于人类活动而引入环境的化学元素。与环境有关的金属表现出非常高的富集系数，在某些情况下超过100。金属粒度分布表明，Pd、Pt、Au、Sb、Zn、S、Ni、V、Mo和Cr主要富集在最细颗粒中，Pb、Br、As、Cu、Ag和Ba几乎不受粒度分数的影响。扫描电镜/能谱分析显示，个别颗粒含有成群的外来颗粒(
Inorganic matter from roadway dust collected in the urban area of Palermo, Italy, was analysed to identify the chemical elements introduced into the environment as a result of human activities. Metals of environmental concern exhibit very high enrichment factors, which in some cases exceed 100. Metal size distribution indicates that Pd, Pt, Au, Sb, Zn, S, Ni, V, Mo and Cr substantially accumulate in the finest particles, whereas Pb, Br, As, Cu, Ag and Ba are almost independent of the size fraction. SEM/EDS analyses revealed that some individual particles contain clusters of foreign particles (
