Wet deposits were collected every month from July 1992 to May 1993 at Yonezawa, which is located 90 km inland from the coast of the Japan Sea. Sulfur isotope ratios of sulfate (δ34Smes) were low in summer and high in winter, linked with the contribution of seasalt sulfate. The δ34Smes values in atmospheric deposits ranged from +1.0 to +8.1‰, which is less than that of seawater sulfate(+20.3‰). This result suggests that the main sources of sulfate in rain and snow in this area did not come from sea spray sulfate. The sulfur isotope ratios for non-seasalt sulfate(δ34Smes)did not show seasonal variation and had an annual mean of +4‰. We conclude that sulfate in the wet deposits contains sulfur-oxides from local human activities.
