Street dust composition is an important environmental parameter that should be considered in investigations of environmental pollution originating from traffic. In this study, fifty-six samples of street dusts were collected during the period December 2003-April 2004 from Pendik to Levent on E-5 highway in Istanbul, Turkey. Analyses were determined by graphite furnace atomic absorption spectrometry after digestion using USEPA, 1996 (Method 3050B). The mean concentration levels of Pb, Mn, Zn, Ni, Cd and Cu were found to be 368.3, 747.8, 431.2, 27.1, 0.3 and 191.1 microg/g respectively. Pb, Cu, Zn and Mn mean concentrations in studied areas were higher than levels of these heavy metals according to USEPA (1992) and Republic of Turkey Ministry of Environment and Foresty (2003). Highly significant correlations except for Mn were found between the number of vehicles and heavy metal concentrations.
街道灰尘成分是一个重要的环境参数，在源自交通的环境污染调查中应予以考虑。在本研究中，2003年12月至2004年4月期间，从土耳其伊斯坦布尔E-5高速公路上的彭迪克到莱文特采集了56个街道灰尘样本。采用美国环境保护局1996年的方法（方法3050B）消化后，通过石墨炉原子吸收光谱法进行分析。结果发现，铅、锰、锌、镍、镉和铜的平均浓度水平分别为368.3、747.8、431.2、27.1、0.3和191.1微克/克。根据美国环境保护局（1992年）和土耳其环境与森林部（2003年）的数据，研究区域内铅、铜、锌和锰的平均浓度高于这些重金属的水平。除锰外，车辆数量与重金属浓度之间存在高度显著的相关性。
