This study was carried out to investigate yearly changes in the precipitation component and the source strength to acid precipitation in the rural area of Chinbuk province by analysis of the chemical components in the precipitation at National Honam Agricultural Experiment Station RDA in the suburbs of Iksan from 1991 to 1995. The average ratio of acid precipitation was 47.9% from 1991 to 1995. pH of the rain water in precipitation below 5mm was higher than that above 5mm and the concentration of the ions in the rain water was the highest in the first fraction$(0{\sim}5mm)$ of precipitation. The amount and ratio of the precipitation below pH 4.0 from 1991 to 1995 were 64mm and 1.4%, respectively. The order of the major ions concentration in the precipitation was $SO_4\;^{2-}$ > $NO_3\;^-$ > $Cl^-$ > $NH_4\;^+$ > $Ca^{2+}$ > $K^+$ ${\lrcorner}\;Mg^{2+}$. The relative contributions to the acidification of the rain in Iksan were 52% from $SO_4\;^{2-}$, 25% from $NO_3\;^-$ and 23% from $Cl^-$.
