خلاصه مقاله:
This paper describes air pollution tolerance among roadside plants exposed to varying degrees of vehicular pollutants. Evaluation of air pollution tolerance index (APTI) of 9 selected plant specieswas carried out to assess their response to ambient levels of air pollutants along East of Esfahancity. Four parameters namely total chlorophyll, ascorbic acid, pH of leaf extract and relative water content were determined and computed together to signify air pollution tolerance index(APTI) of plants. Stress metabolites like ascorbic acid and chlorophyll of certain plant speciesexhibits different levels of sensitivity and tolerance towards air pollution. The highest and thelowest deposition rates were observed in Morus alba and Cercis sliquastrum, respective ly. Amongthe nine different plant species examined, APTI value is maximum in Morus alba suggesting its higher tolerance. The Ornamental shrubs with lower APTI values (sensitive) were recommended to be utilized as bioindictors of poor urban air quality while shrubs with high APTI values (Tolerant) are to be planted around areas anticipated having high air pollution load
