It is a fact that forests and jungles have the capacity to nullify the ill effects of the toxic gases. It is well recognized that plants play an important role in reducing air pollutants including toxic gases. Government is encouraging green belt in the industrial premises, urban conglomerates, road sides etc. While granting environmental clearance to industrial projects, the Ministry stipulates a condition to develop green belt for mitigating air pollution as per the guidelines issued by the Central Pollution Control Board (CPCB).
The Air Pollution Tolerance Index (APTI) determined on the basis of leaf extract PH, ascorbic acid, total chlorophyll and relative water content varies among different plant species. Some studies have indicated that Ficus, Albizia, Pithecelobium, Phyllanthus and Polyalthia are some of the trees having high APTI.
