RELATION BETWEEN VEHICLE TRAFFIC AND HEAVY METALS CONTENT FROM THE PARTICULATE MATTERS

摘要

The aim of this paper is to prove relation between vehicle traffic and heavy metals content, lead and cadmium, from suspended particulate matters. The field study was conducted for a year in a street canyon with high vehicle traffic (Pitesti), which can be considered hot spot, by comparison with a blank area, without vehicle traffic (Calinesti, Arges). Heavy metals contents were determined after 24 hours samplings along 2008. In urban area, lead content is higher during working days, whereas cadmium content remains constant. Moreover, correlations between lead, carbon monoxide and PM10 are much better than in rural area.
