Abstract :
Development of a green belt with suitable plant species around the
source of emission can mitigate the atmospheric contamination. Selection of
such plant species are required to combat air pollution based on their tolerance
level. Present study was undertaken to evaluate the tolerance level of higher
plants in East of Esfahan city, Iran, during 2011 in terms of assessing Air
Pollution Tolerance Index (APTI). Leaf extract of nine plant species showed
elevated levels of pH, ascorbic acid, chlorophyll and relative water content.
Stress metabolites like ascorbic acid and chlorophyll of certain plant species
exhibits different levels of sensitivity and tolerance towards air pollution. Dust
deposition on leaf surfaces was estimated to observe the extent of particulate
deposition. The highest and the lowest deposition rates were observed in
Morus alba and Cercis siliquastrum, respectively. Among the nine different
plant species examined, APTI value is maximum in Morus alba suggesting its
higher tolerance.
