Research Abstract

We have measured atmospheric concentrations of aerosol chemical species less than 2mum in diameter (atmospheric fine particles) and gaseous SO_2, HNO_3 and HC1 from August 1993 at Yakutsk, Tiksi and Norilsk in Siberia. We also measured atmospheric concentration of SO_2 and NO_2 in summer at Habarovsk, Yakutsk and Norilsk.
At Yakutsk most of the fine particles consisted of elemental carbon and organics whose concentrations were the same as those in Sapporo. At Tiksi the atmospheric fine particle concentration was one-tenth of those at Yakutsk. Most of the fine particles consisted of organics and sulfate. At Norilsk elemental carbon, organics and sulfate accounted for most of the fine particles whose concentration was the same as in Sapporo. The sulfate particle concentration, in particular, increased in spring and summer.
Atmospheric summer concentrations of SO_2 and NO_2 were low at Habarovsk and Yakutsk. But, in Norilsk, though NO_2 concentration was low, the concentration of SO_2 was extremely high in summer.
We evaluate the effects of atmospheric pollutants on the Arctic environment.
