title: Difference in sulphur accumulation in eleven tropical tree species growing in polluted environs.
abstract: 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.
