Introduction: Air pollution caused by the pollutants present in the atmosphere which is harmful to theenvironment and the living population. The plants showed stunted growth, animal’s causes various formof diseases and the pollutants harmfully affect the human beings by causing respiratory problems and thewhole environment is totally affected causing depletion of ozone layer and that directly or indirectly affectsthe living system present in the environment.Materials and Method: The leaf samples were collected from the Sholinganallur area and authenticated.Later the samples were characterized for morphological characters, pigment analysis, Biochemicalparameters and the score of tolerance index of Air pollution was calculated were tabled and graphed as perthe standard protocol.Results: The samples were collected from sholinganallur traffic zonal area and totally 14 leaf samples weregathered from the experimental site and was authenticated. The morphological characters of length andwidth of leaf samples were calculated and in Biochemical parameters, pH of leaf, Relative water contentand ascorbic acid content showed good activity in evergreen shrub. In pigment analysis of chlorophyll,the maximum and minimum amount was found in evergreen shrub Bougainvillea glabra with 68.72mg/gand Tecoma capensis in 14.72mg/g. The APTI value was maximum and minimum in evergreen shrubTabernaemontana divaricata with 114.66 and Nerium oleander with 48.05.Conclusion: The plants found in and around the experimental area possess good activity against the airpollution and these plants can be kept at the roadside to prevent and withstand the air pollution in theenvironment.
