Abstract
Trees vary considerably with their susceptibility to Air pollution. Cultivation and conservation of certain trees which are fast growing, resistant and sensitive to certain pollutant can make environment free from pollution to some extent. In present study the susceptibility level of plants to air pollutants, have been evaluated on the basis of their APTI value. For the purpose four parameters namely ascorbic acid, leaf extract pH, relative water content and total chlorophyll were determined and computed in the formula proposed by Singh and Rao (1983) to get APTI. The plants with low APTI value were categorised as sensitive and with high APTI as tolerant because the former can serve as indicator and latter as sink for the abatement of air pollution.
