Sažetak
The relationship of polycyclic aromatic hydrocarbons (PAH) and smoke concentration was analysed at four different locations in Zagreb during the heating season. At two sampling sites smoke pollution came primarily from domestic heating while the other two sites were under a direct influence of traffic. At locations away from traffic correlations between smoke and PAH concentrations were stochastically significant at 0.01 level. Taking benzo-a-pyrene (BaP) as PAH representative it was shown that for these two locations the smoke/PAH relationship can be presented with a single regression line which can serve for rough assessment of BaP levels in the air. The BaP concentration of 10 ng/m3 - proposed by the German Federal Environmental Agency as "orientation < mark" (Lahman et al., 1984) - might be expected to occur at smoke levels >=60 mcg/m3, and above this level it is recommended to start measuring actual concentrations of PAH.
