BENZENE IN THE AIR OF ZAGREB, CROATIA – FIRST STUDY

This paper presents the results of the first measurements of benzene concentrations in the air of Zagreb, Croatia. The samples were taken at two sampling sites and analysed every 15 minutes using automatic gas chromatographs. One sampling site was the national monitoring station located in a densely populated city centre with high dense traffic. The other sampling site was a regional monitoring station in the northern part of the city with small population density and low traffic. The measurements were carried out simultaneously at both sampling sites from May 19 to August 16, 2004. The results showed diurnal variations characteristic of urban areas and the influence of traffic, with higher values measured in the morning hours. Both sampling sites showed differences in benzene concentrations between working days and weekends. When comparing benzene levels between the two sampling sites it was found that benzene concentrations were lower in the northern part of the city throughout the sampling period.
