Contribution of biomass burning to atmospheric polycyclic aromatic hydrocarbons at three European background sites

Original language description

Radiocarbon analysis of atmospheric polycyclic aromatic hydrocarbons (PAHs) from three background areas in Sweden, Croatia and Greece was performed to apportion their origin between fossil and biomass combustion. Diagnostic ratios of PAHs implied that wood and coal combustion was relatively more important in northern Europe, while combustion of fossil fuels was the dominant source of PAHs to the southern European background sites. The stable carbon isotopic composition (d13C) of PAHs ranged from -29.2 to -27.7, suggesting that diesel combustion is of minor importance in all areas. The radiocarbon content (Ä14C) of atmospheric PAHs in Sweden ranged between -388 and -381, while more depleted values were observed for Greece (-914) and Croatia (-888). Using a 14C isotopic mass balance model, it was calculated that biomass burning contributes nearly 10% of the total PAH burden in the studied southern European atmosphere with fossil fuel combustion making up the 90% balance. In contrast, bio
