Effects of vehicular exhaust on biochemical constituents Of leaves of roadside vegetation
Air pollution is one of the serious environmental concern of the urban Asian cities including India where majority of the population is exposed to poor air quality. The health related problems such as respiratory diseases, risk of developing cancers and other serious problems due to poor air quality are known and well documented. Motor vehicles are the major source of a number of these pollutants, in particular, carbon monoxide, nitrogen oxides, unburnt hydrocarbons and lead and, in smaller proportions, suspended particulate matter, sulphur dioxide and volatile organic compounds, and via atmospheric transformation of ozone and other photochemical oxidants.With growing urbanization and increase in vehicle density, and the great expense of pollution control, urban air pollution has become a crucial problem and it is now urgent to undertake risk assessments in order to evaluate and prioritize control strategies. In the present work effect of air pollution on three different plant species selected for the study at three sampling sites. Plant species namely were Dahlia x hybrid, Bougainvillea spectabilis and Leucaena leucocephala were studied in three zones having low, medium & high traffic density. The parameter studied were chlorophyll content, total carotenoid, relative moisture content, leaf area total sugar and protein. The results revealed that reduction in chlorophyll content, sugar and protein, relative water content and APTI was recorded in the leaf samples of all selected plants collected from polluted site area. A significant negative correlation was found between ambient air quality and biochemical parameters which exhibited significant positive correlation with pollution load.
