ROLE OF PLANTS FOR EVALUATION OF AIR POLLUTION TOLERANCE INDEX ON THE BASIS OF SOME BIOCHEMICAL PARAMETERS: A CONCISE REVIEWAnirban Paul, Sandipan Chatterjee, Chandrik Malakar and Hemanta SahaAbstract Several common plants such as, Mangifera indica, Pinus roxburghii, Thuja occidentalis, Tamarindus indica, Cassia fistula, Dalbergia sissoo, Quercus sp., Bauhinia recemosa etc. are available to absorb various pollutant gases. Plant leaves are the ideal indicator to measure the degree of air pollution and most plant have exhibited various physiological changes before showing any visible symptom in the leaves. Air pollution tolerance index (APTI) is a simple and efficient method for identifying plant species that can tolerate air pollution. It only requires four different types of leaf biochemical parameters, including the pH of plant leaf extract, the relative water content of the leaf, ascorbic acid, and the total chlorophyll content of the leaf. The amount of plant susceptibility to air pollution was assessed using the APTI score. Higher APTI-valued plants are extremely beneficial as a bio-monitoring tool for improving the atmosphere. For plantation programmes in newly constructed urbanized areas and avenues to produce pollution-free green environments, plant species with higher APTI values can be prioritized. |
