This paper is to investigate and study characteristics of Rainfall in Busan area. Acid rain samples were collected in Hadang site. Samples were measured for pH, EC and ion composition(SO_(4)^(2-), NO_(3)^(-), Cl^(-), H^(+), Na^(+), NH_(4)^(+), K^(+), Mg^(2+), Ca^(2+)).
In 1st rainfall, pH was about 4.4∼6.1 in sampling period. Maximum is 6.1 in 1998 and minimum is 4.4 in 1994. In 2nd rainfall, pH was about 4.1∼5.8 in sampling period. Maximum is 5.8 in 1998 and minimum is 4.1 in 1994.
In seasonal pH variation, pH range was 4.9∼6.1 in spring, 4.9∼6.1 in summer, 4.7∼6.9 in autumn and 4.3∼6.0 in winter.
In seasonal EC variation, EC range was 14.9∼60.5 ㎲/㎝. In 1st rainfall, EC was 46.1∼91.3 ㎲/㎝ in spring, 29.6∼42.6 ㎲/㎝ in summer, 38.1∼101.5 ㎲/㎝ in autumn and 48.3∼73.3 ㎲/㎝ in winter. In 2nd rainfall, EC was 10.8∼42.1 ㎲/㎝ in spring, 15.6∼27.1 ㎲/㎝ in summer, 11.2∼34.9 ㎲/㎝ in autumn and 18.7∼44.0 ㎲/㎝ in winter.
