Sažetak
Polycyclic aromatic hydrocarbons (PAH) are organic compounds that consist of two or more aromatic rings. More than 500 PAHs have been identified in the air and they were among the first pollutants established as potential carcinogens. The most investigated PAH is benzo(a)pyrene (BaP), which is considered a representative of the group. European Union (EU) and Croatian air quality legislation is fundamentally based on BaP in the PM10 particle fraction (particles with an aerodynamic diameter smaller than 10 μm). In Zagreb, the capital of Croatia (~800 000 inhabitants), measurements of BaP in PM10 started in 2001 at one measuring site. This measuring station is located in the northern residential part of the town close to a street with modest traffic. 24-hour samples of PM10 particle fraction were collected on quartz filters using a low-volume sampler from about 50 m3 of air. The analysis was performed using a high performance liquid chromatograph (HPLC) with a fluorescence detector and time programmed changes in excitation and emission. During a fifteen-year period (2001-2015), annual BaP concentrations ranged from 0.735 ng/m3 to 1.789 ng/m3. The maximum 24-hour average of BaP concentration was measured in 2003, and was 18.283 ng/m3. The highest values were measured at the beginning (2001-2006), when the annual averages exceeded the EU target value of 1 ng/m3. Annual BaP concentrations were the lowest between 2007 and 2009 ; however, the target value was surpassed again in 2010-2012 and in 2015. In general, BaP concentrations have decreased during the last fifteen years. The decrease was most pronounced during the first seven years. However, a slight increasing trend of annual averages was recorded for the last seven-year period (2009-2015). The possible causes may be increasing motor vehicle traffic and increased use of solid fuels during heating season.
