Foliar surface of plants is continuously exposed to the surrounding atmosphere and is therefore the main receptor of dust. This physical trait can be used to determine the level of dust in the surroundings as well as the ability of individual plant species to intercept and mitigate with it. The present research was undertaken to study the dust deposition efficiency of selected common roadside plant species and the response of dust deposition on the biochemical aspect of leaves such as pH, Relative water content and Total chlorophyll content. The result showed maximum dust deposition in winter followed by summer and rainy for all plant species. It was seen that total chlorophyll and relative water content decreased whereas pH of leaf extract increased with the increasing dust load. The result shows significant negative and positive correlation between dust deposition and RWC, Total chlorophyll and pH respectively. The highest and the lowest dust deposition rates were observed in Ficus bengalensis and Artocarpus heterophyllus, respectively. Thus plants can be used in the abatement of dust pollution by acting as natural filters.
