The present study was aimed to find out the differences in sulphur accumulation in eleven tropical tree species exposed to air pollution containing higher levels of sulphur dioxide. Sulphur content in the leaves and branches were studied at three different polluted sites. The results were compared with a control--25 km away from the industrial belt. The results revealed a positive correlation between the atmospheric sulphur dioxide concentration and foliar sulphur content. In few tree species higher accumulation of sulphur within the branches were recorded. The paper discusses about the trees which could be planted as sulphur accumulators.
本研究旨在找出暴露于含较高二氧化硫水平空气污染中的11种热带树种在硫积累方面的差异。在三个不同的污染地点研究了树叶和树枝中的硫含量。将结果与距离工业带25公里处的对照地点进行了比较。结果表明大气二氧化硫浓度与叶片硫含量之间存在正相关。在少数树种中，记录到树枝内硫的积累量较高。本文讨论了可作为硫积累植物种植的树木。
