These have resulted in significant rise of the air pollutants over the city atmosphere; which is affecting human population, other animals and also the plant community. Although 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. Based on this absorbing power and tolerance limit, vegetations can be classified as Highly Tolerant, Moderately Tolerant and Sensitive.
