- Abstract
Clean air, pure water and nutritious food are basic amenities of life but the quality of air, water and land is deteriorating continuously. Air Pollution is any atmospheric condition in which certain substances are present in such concentration that can produce undesirable effects on man & its environment Industrial air pollution is more complex than most other environmental challenges. Air pollution tolerance level differs from plant to plant. To evaluate the tolerance level of plant species to air pollution, four leaf parameters are used to drive an empirical number indicating the Air Pollution Tolerance Index (APTI). Air pollution tolerance index has also been used to rank plant species in their order of tolerance to air pollution. The aim of this study is therefore to determine the APTI values of six plants species which were collected from 9 sites of Baroda city. Leaf samples of selected plant species found at all the sampling sites were collected i.e Azadirachta indica, Polyalthia longifolia, Ficus bengalensis, Mangifera indica, Acacia arabica & Peltophorum pterocarpum in three different seasons (Monsoon, Winter& Summer). Chlorophyll value was highest during monsoon season & decreased in winter and summer. All the plant samples collected from polluted site exhibited a pH towards acidic side. Present study showed higher leaf relative water content in all the species was in monsoon season. Whereas the higher average ascorbic acid concentration was found in winter season followed by summer and least in monsoon. Based on the highest calculated APTI irrespective of the season the plants were found to having the following order Polyalthia longifolia>Azadirachta indica>Ficus bengalensis> Acacia Arabica>Peltophorum pterocarpum>Mangifera indica. But if the average APTI values of all the season is to be considered then the order will be as follows: Azadirachta indica>Polyalthia longifolia>Mangifera indica>Ficus bengalensis> Acacia arabica>Peltophorum pterocarpum. Except Acacia all the other species showed insignificant seasonal variation in APTI according to ANOVA, α=0.05. So far, this aspect of pollution management was not studied in the study area. So, this study may particularly be helpful for the air pollution management of the city specially during aforestation programmes.
