Present study deals with the relationship between ambient air sulphurdioxide 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.
本研究探讨了环境空气中二氧化硫与选定热带植物物种——菩提树叶片中硫酸盐含量之间的关系。研究揭示了环境空气中二氧化硫与叶片中硫酸盐之间存在正相关。双向方差分析发现所获得的值具有高度显著性（p < 0.001）。在研究的大部分时间里，叶片中硫酸盐的含量与空气中的二氧化硫呈正相关（p < 0.001）。在10月份，当记录到环境空气中二氧化硫减少时，发现叶片中硫酸盐含量显著降低。
