Sažetak
Polycyclic aromatic hydrocarbons (PAH) are compounds known for their adverse effects on human health. Many of them are proven carcinogens, especially those with 5 and 6 aromatic rings, which are usually in the particle-phase under normal tropospheric conditions. Benzo(a)pyrene (BaP) is often measured as their general representative. Sarajevo, the capital of Bosnia and Herzegovina, is among European cities with the poorest air quality. However, measurements of PAH are not part of routine monitoring. The capital of Croatia, Zagreb, is located approximately 300 km air distance north-west from Sarajevo. PAH mass concentrations in Zagreb have been measured continuously since 1994 within air quality monitoring networks. During winter 2017/2018, the SAFICA project (Sarajevo Canton Winter Field Campaign 2018) was carried out in order to characterise organic and inorganic pollutants in the city of Sarajevo and its surroundings. This paper presents results of PAH measurements at one urban location in Sarajevo. 24-hour samples of the PM10 (particulate matter with aerodynamic diameters ≤ 10 μm) were collected during heating season, from 10 December 2017 to 27 February 2018. PAH mass concentrations in Sarajevo were compared with results obtained in Zagreb during the same period. Average BaP concentrations in Sarajevo and Zagreb were 6.925 ng m-3 and 3.109 ng m- 3, respectively. The contribution of BaP to the sum of PAH mass concentrations was similar at both locations (~11 %). However, much higher contributions of fluoranthene and pyrene were obtained in Sarajevo. Contributions of individual PAH and their diagnostic ratios indicated combustion of gasoline and diesel as a potential source of PAH (traffic) at both locations, as well as combustion of other liquid fossil fuels (petroleum, crude oil). Wood burning was occasionally indicated as a source in Zagreb, while in Sarajevo the contribution of wood and coal combustion was evident. The total carcinogenic potency (TCP) of PAH was estimated using toxic equivalence factors from the literature and it was more than twice higher in Sarajevo compared to Zagreb. BaP had the highest contribution to the TCP at both locations (69 and 67%).
