Abstract
Precipitation samples collected from seven sites situated in a major industrial region in Bombay during 1980 monsoon period were analysed for pH, SO4' CI, NO3, NH4 and F ion concentrations. Barring one site which showed predominantly acid rains, samples from other sites were found to be alkaline in nature. Data obtained suggest a predominant SO4 excess at two of the sites where the prime source is SO2' Higher levels of fluoride and nitrate were found at four of the sites indicating a local source. SO4, and NH, excesses are estimated with reference to their stoichiometric ratios. Fluoride deposition due to precipitation washout around the fertilizer industry is assessed and the overall results of the study discussed.Keywords
