Abstract:
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 canyon street with high vehicle traffic in Pitesti, which can be considered hot spot, by comparison with a blank area in Calinesti, Arges, without vehicle traffic and away from any industrial activities influence. Heavy metals contents were determined after 24 hours samplings along 2008.The annual average of lead content in PM10 particulate matter is about 20 times higher in urban area than in rural area (blank), relative to cadmium content that is only 2 times higher. Otherwise, in urban area, lead content is higher during working days, whereas cadmium content remains constant.In rural area both lead and cadmium content in the air is approximately constant in all week days. Moreover, correlations between lead, carbon monoxide and PM10 are much better than in rural area and prove the high influence of vehicle traffic to the heavy metals contents, especially lead.
