Sažetak
Mass concentrations of eight polycyclic aromatic hydrocarbons (PAHs) were measured in inhalable particle fraction PM10 (particles with equivalent aerodynamic diameter 10  m or less) and in respirable particle fraction PM2.5 (particles with equivalent aerodynamic diameter 2.5  m or less). The aim of this research was to establish the existence of statistically significant differences in PAHs mass concentrations measured in PM10 and PM2.5. The 24-hour samples of PM10 and PM2.5 were collected simultaneously on glass fibre filters by means of two low-volume samples (50 m3 of air) over the period of 30 consecutive days in January 2001, at one measuring site located in the northern part of Zagreb. Samples were extracted with cyclohexane and analysed with HPLC and fluorescence detector. Benzo(a)pyrene (BaP) is one of the best known and most common PAH with the most investigated cancerogenic effect. The average mass concentration of BaP, measured in PM10, was 3.04 ng/m3 and in PM 2.5 3.17 ng/m3. Although the average mass concentrations of all measured PAHs, except BaP and BghiP, were slightly higher in PM10 fraction, the differences of PAH measured in both fraction were not statistically significant. The results show that all PAHs are found in respirable particle fraction. This finding is in good agreement with the findings of numerous authors who found that BaP and the other PAHs, with more benzene rings, are absorbed on the particulate matter of small sizes which enter directly into respiratory system.
