Summary

In connection with the investigation of acid depositions, a reliable method for the determination of the cosmogenic radionuclide 35S in precipitation was developed, and atmospheric depositions of 35S and SO42- have been measured every ten days at Tatsunokuchi,in a heavy-snowfall area facing to the Sea of Japan for two years during 1998-1999. Consistent seasonal cycles were found for the atmospheric depositions of 35S and non-sea salt sulfate (nss-SO42-),   in which both depositions were high in winter and low in other seasons. A similar wet scavenging mechanism was suggested to be involved in the association of 35S and SO42-.
