This paper will present the latest available data of the levers of PAHs in the ambient air conducted in Finland. The sampling sites were situated in the metropolitan area of Helsinki. It will also compare the latest data against the data obtained in the 1980'ties. Information about the sources can be obtained by comparing emission ratios and profiles of target compounds. All measurements were made using gaschromatography mass spectrometry singel ion monitoring (GCMS-SIM).
