Sažetak
Due to the fact that some PAHs are mutagenic and the others are carcinogenic they should not be present at all in the air or their concentrations should be the lowest possible. This paper presents PAHs measured in samples of suspended particulate matter (SPM) collected in one network station in the northern part of Zagreb and in a rural area about 50 km away from Zagreb in 1998 in all seasons. The samples were collected with a high volume sampler over a 24-hour period on glass fibre filters, and analysed with high performance liquid chromatograph (HPLC) and a fluorescence detector. The results show that PAH mass concentrations measured in the urban and the rural area were similar in spring and autumn. The spring PAH concentrations in the urban and rural area were about ten times lower than the autumn ones, as the spring has more sunny and warm days. Mass concentrations of all measured PAHs in the summer were higher in the rural area, due to summer works around household with tractor, but only for BaP the differences were statisticaly significant (P<0.02). The concentrations in winter were higher in the urban area, but the differences were statistically significant only for BghiP (P<0.02). The highest concentrations of all PAHs were measured in winter. Mass concentrations of PAHs during throughout the measurement period were slightly higher in the urban air, but the differences were statistically significant (P<0.02) only for BghiP, which is associated to car exhausts that is, intense city traffic. The average value for BaP in the urban area was 1.87 ng/m3 and in the rural area 1.55 ng/m3. Both are below the limit value (2 ng/m3) set by the Ordinance on Recommended and Limit Air Quality Values in Croatia.
