Twenty plant species were selected for present study. Out of 20 plants 3 species are herbs, two species are tree species and 15 are shrubs. In the present study only chlorophyll content was calculated as a physiological parameter. The present study clearly establishes that the reduction in the level of of pigment due to air pollution except the Leucaenalati siliqua, Duranta erecta, Annona squamosa, Hibiscus rosa-sines is the content of pigment was same in the Psidium guajava and Nerium. Therefore, plant quickly responds to air pollutants and this is brought out by the modification of various fruits in them. Hence they can be utilized as biological indicators of air pollution. The present study on clearly establishes that the experimental sites chosen in this study is highly polluted.
