Analysis of wet acidic deposition in Petaling Jaya
Ten year (1982-91) wet fallout data published by Malaysian Meteorological Services has been analyzed to find the trend and nature of acidic deposition in Petaling Jaya. The pH of rainwater shows a downward trend, indicating gradual increase of acidity with time. Seasonal variation of pH and ionic co...

| description | Ten year (1982-91) wet fallout data published by Malaysian Meteorological Services has been analyzed to find the trend and nature of acidic deposition in Petaling Jaya. The pH of rainwater shows a downward trend, indicating gradual increase of acidity with time. Seasonal variation of pH and ionic concentration of SO--, NH4+ and Ca++ in rainwater shows that SO4-- is the main source of free acidity in the wet deposition, while Ca++ and NH4+ ions act to neutralize the free acidity |
