Abstract: Present study deals with the relationship between ambient air sulphur dioxide and sulphate content in leaf of selected tropical plant species, Ficus religiosa. The study reveals a positive correlation between ambient air sulphur dioxide and sulphate in the leaves. Two way ANOVA finds the obtained values to be highly significant (p<0.001). Amount of sulphate in leaves shows positive correlation with sulphur dioxide in air (p<0.001) during most part of the study. A marked reduction of sulphate content  in leaf was found during October when reduction in ambient air sulphur dioxide was recorded.

Key words:   Macronutrient, Cysteine, Brick kilns, Coal, Ficus religiosa
