Fine aerosol Polycyclic Aromatic Hydrocarbons (PAHs), Oxygenated (OPAHs) and other PM2.5 components were quantified in Ioannina, a Southeastern European city facing severe air quality degradation due to residential biomass burning (BB). Compound (PAC) seasonal means extremely enhanced winter compared summer (by 98 88 times for PAHs OPAHs, respectively). Benzo(a)pyrene (BaP) registered 347-fold increase, its estimated annual mean was 2.4 higher than the EU standard. Medium- high-molecular weight PAC species correlated well with DTTv activity (R2: 0.48 0.54, respectively), suggesting also their significant non-carcinogenic potential. These groups strongly associated methanol- water-soluble Brown Carbon absorption (R2 > 0.7). Source apportionment by Positive Matrix Factorization (PMF) on speciation dataset indicated BB as major source, contributing 80 % average Σ-PAC concentrations carcinogenic potential during study period. The risk assessment highlighted importance of considering inclusion not only legacy but emerging very high toxicity, such Benzo(c)fluorene Dibenzo-pyrenes. Observed alarming, posing substantial short- especially long-term risks. Therefore, there is an urgent need regulate Ioannina similar urban environments SE Europe.
