摘要：In the present day highly populated, urbanized, industry-based world, dust in the form of suspended particulate matter (size <10 μm) is one of the major key sources of air pollution that severely affect the human health. Plants with various canopy cover, pattern of phyllotaxy and leaf texture have the ability of retention of that dust particles from the ambient air. In the present study, four tree species Alstonia scholaris, Neolamarckia cadamba, Ficus religiosa and Ficus benghalensis were selected to understand the variation of dust deposition capacity in a metropolitan city, Kolkata, through a time scale of day length. Result reveals that Alstonia scholaris has the maximum retention capacity of dust particles followed by the Neolamarckia cadamba, Ficus religiosa and Ficus benghalensis. And the pattern is same in different time interval of the day, even during heavy traffic. The study would be helpful in urban development planning for selection of tree species towards mitigation of dust pollution.
