To reveal chemical characteristics of rime in 2002/2003, rime samples were collected at 1670m altitude on Mt. Zao, Yamagata Prefecture, Japan, from December 6th 2002 to April 1st 2003. Mt. Zao is suitable for monitoring air pollution because there is no source of exhaust such as volcano or human emission west of Mt. Zao.<BR>The Yellow sand phenomenon occurred frequently in 2000, but not 2002. Concentrations of soluble substances and particulate matter in the rime were measured. Mean pH was 4.2 in 2002/2003. The total acidification component (nssSO42- + NO3-) was always more abundant than the neutralization component (nssCa2+ + NH4+) . Mean concentrations of nssSO42-, NO3- and NH4+ were the same in 2000/2001 and 2002/2003. However, mean concentrations of nssCa2+ and particulate matter in 2002/2003 were almost half those in 2000/2001. The concentration of nssCa2+ was closely related to that of particulate matter. The acid rime was neutralized by non-sea salt calcium, dissolved from particulate matter. These results suggest that the rime was not neutralized in 2002/2003, because yellow sand was not abundant in 2002/2003.
