Abstract
Air pollutants affect the morphological, physiological, and biochemical conditions of plants, with their effects differing significantly across various species. In this study, 25 varied plant species were collected from various activity zones, including heavy traffic areas, industrial sites, commercial districts, residential neighborhoods, and a control zone. The air pollution tolerance indices (APTI) of twenty-five plant species were assessed by analyzing various biochemical parameters of the leaves, including ascorbic acid, chlorophyll, relative water content, and pH of leaf extract. The findings indicate that every examined plant species fall under sensitive category ranging from 14.20 (Ficus religiosa) to 8.24 (Solenostemon scutellarioides). The results indicate that, all the biochemical parameters show the deterioration with the increase of intensity of pollution.
