The concentrations of PAHs, hopanes and ααα (20R)-cholestane were measured in PM1 aerosols during winter and summer campaigns in 2009 and 2010. Analysis of source specific molecular markers and diagnostic ratios of PAHs and hopanes were employed to identify the main emission sources of these compounds. Diagnostic ratios imply that during winter the origin of PAHs was mainly from coal/biomass burning while hopanes originate mainly from coal combustion. During summer season, traffic is proposed as the main emission source of particulate PAHs and hopanes.
