Identification and Evaluation of Air Pollution Tolerance Index of Selected Avenue Tree Species of Urban Bangalore, India
نویسنده
چکیده
The resistivity and susceptibility level of tree species to air pollution within avenue’s of Urban Bangalore has been evaluated on the basis of Air Pollution Tolerance Index (APTI) value. Four parameters namely Leaf extract pH, Total Chlorophyll Content, Relative Water Content of Leaf and Ascorbic Acid content were determined and APTI was computed. The tree species with higher APTI values like Polyalthia longifolia, Albizia saman, Azadiracta indica, Pongamia pinnata, Swietenia mahogany, Michelia champaca, Millingtonia hortensis and Tamarindus indica are tolerant to air pollutants and can be used as an effectively indicators and pollution scavengers. The tree species having higher APTI value can be given priority for plantation program in newly urbanized areas and avenue’s of Urban Bangalore; so as to reduce the stress of motorists at traffic junctions, effect of air pollution and make the environment clean for healthy life.
