Levels of Selected Metals in Ambient Air PM10 in an Urban Site of Győr, Hungary

Abstract

The aim of this study was to assess the ambient concentrations of some selected trace metals (Pb, Cd and Ni) and the metalloid As in the PM10 aerosol fraction in an urban site of Győr, Hungary in 2011. The results show that the study area has excellent air quality with respect to metal(loid)s during the four sampling periods. However, the annual average concentration of PM10 indicates a polluted area. The PM10 concentrations were higher in heating season than in summer time. The levels of PM10 and trace elements determined were compared with other cities located in Hungary and around the world.
