Assessment of air quality using several bio monitors of selected sites of Durgapur, Burdwan district by air pollution tolerance index approach

Rapid industrialization leads a great role over pollution. Vegetation can absorb particulate and other gaseous pollutants into their system but they also have some limitation and tend to show symptoms of damages after prolonged exposure. Several parameters including ambient air quality monitoring as well as ascorbic acid, pH, total chlorophyll, relative water content of ten different crop species at four different sites were analyzed to evaluate the Air Pollution Tolerance Index of Durgapur, Burdwan District, West Bengal, India.From the detailed study it was found that the highest APTI valueshowed in Polyalthialongifolia (176.14) at Durgapur College Campus, Nacicasesum (158.68) at Durgapur Projects Limited, Polyalthialongifolia (133.26) at Amaravati and Moringaoleifera (129.32) at Mamrabazar. Therefore these tree species could act as the bioindicators for pollutants and could be utilized as tolerant species towards combating air pollution..
