Individual rain event samples were collected at three sites in and around Kuala Lumpur from
May, 1.982 to May 1983. The samples were analysed for pH, anions (sulphate, nitrate, chloride and
fluoride) and cations (calcium, magnesium, sodium and potassium). Correlation and regression analyses
indicated that the major anions appeared to be more closely associated with the cattons than the hydrogen
ion. Pollutants from both natural and anthropogenic sources appeared to have contributed to the chemical
composition of precipitation
