EXPOSURE TO PARTICULATE MATTER AND HEAVY METALS IN THE POPULATIONS OF CENTRAL ZONES OF BELGRADE

Abstract

Particulate matter (PM) is hazardous to human health. This paper deals with PM concentrations inambient and indoor air on three locations (two being in the central parts of the city and another onenearindustrial zone of the settlement of Lazarevac, lying in the outskirts of Belgrade). The aim of thepaper is to assess the scope of exposure to particulate matter and heavy metals (Pb, NI, Cr, Cd and As)adhered to them. Concentrations of PM in indoor air in the central zones of the city are lower than thesemeasured in ambient air. We concluded that the air is predominant source of heavy metals andmetalloids in the environment. Since people spend more than 80% of the time indoors, the control andelimination of local sources of pollution may significantly reduce the scope of exposure to individualpollutants.
