ABSTRACT

 

Urban air pollutants like particulate matter, sulphur dioxide, nitrogen oxides, ozone etc. can harm the plants. It can absorb through stomata and affects adversely its biochemical constituents and physiological process. The variation in biochemical parameters in the leaves can be used as indicators of air pollution for early diagnosis of stress or as a marker for physiological damage prior to the onset of visible injury symptoms. In this study, four physiological and biochemical parameters, viz., leaf Relative Water Content (RWC), Ascorbic Acid content (AA), Total leaf Chlorophyll (TCh) and leaf extract pH were used to compute the Air Pollution Tolerance India (APTI) values of some plant species in different locations along the National Highway No 8 Kisehangarh toll to Bagru toll .The plant species having higher APTI value can be given priority for plantation program in urbanize and industrial areas, so as to reduce the effects of air pollution and to make ambient atmosphere clean and healthy.
