The present study evaluates the relationship between air pollution stress and biochemical characteristics of selected plants such as Azadirachta indica A.juss, Polyalthia longifolia chinensis Benth. & Hook. , Delonix regia Boj.ex Hook., Ficus religosa Linn. Alstonia scholaris Linnconducted at Sarita Vihar,New Delhi in which main traffic site was identified for the collection of leaf sample. An attempt was made to estimated biochemical changes like Ascorbic Acid, Total Cholorphyll content, pH of leaf extract, Relative water contentin selected plants and air pollution tolerance index (APTI) of plants also calculated by using these four biochemical parameters. It reveals that selected plants are having impact and it can be used as a bio indicator of air pollution. It was observed that vegetation at road side with heavy traffic was much affected by vehicular pollution at compare to away from road side. Significant decrease in total chlorophyll pHetc. was observed with reduced leaf area. It was concluded that plants can be used as indicator for urban air pollution and there is need to protect the roadside plants from air pollution.
