We measured SO2 and NO2 gas concentrations by using passive samplers in Siberian urban area (Norilsk, Yakutsk, Khabarovsk, Neryunguri). In Norilsk, SO2 gas concentrations were more than ten times higher than that in Sapporo. In other cities, however, SO2 and NO2 gas concentrations were the same or less than that in Sapporo. Continuous measurement of gas and aerosols in Norilsk showed that extremely high concentrated SO2 gas and sulfate damage forests around Norilsk, and may affect human health. In Yakutsk, Atmospheric aerosols contained much carbonaceous components. In Tiksi, the Arctic haze occurred in winter and spring, which was caused by long range transport of pollutants emitted from Norilsk or west Siberia. The deposition of pollutants as heavy metals may cause the accumulation in the surface of the Siberian Permafrost layer.
