During the summer of 2018, we monitored the concentrations of water-soluble acid gases and particulate anions at the southeastern foot (1284 m a.s.l.) of Mt. Fuji, Japan, using gas/particle-ion chromatographs. All samples analyzed contained quantifiable levels of anions. The average concentrations of acid gas and particulate anion concentrations were, respectively, 1.10±0.37 nmol m−3 for HCl, 3.49±1.72 nmol m−3 for HONO, 1.23±0.59 nmol m−3 for HNO3, 0.33±0.20 nmol m−3 for SO2, 3.61±3.69 nmol m−3 for Cl−, 0.65±0.22 nmol m−3 for NO2−, 4.29±2.98 nmol m−3 for NO3−, and 4.47±3.57 nmol m−3 for SO42−. We found that the concentration of soluble acidic gases increased during the daytime, while no characteristic diurnal patterns were observed in the particulate anions.
