Abstract: Automobile exhaust contains a large number of air pollutions. Among the important constituents of pollutants are carbon monoxide, unburnt hydrocarbons, Nitrogen oxide, particulates and lead. These vehicle pollutions adversely affect Avenue trees by chlorosis, damage leaves and reduces Nutrient uptake. In the present study chlorophyll content of four Avenue trees- Ficus religiosa, Ficus bengalensis, Delonix regia and Cassia fistula was estimated and compared with that of trees far away from the road side.
