Plants are universal sink of CO2. The plant species selected for the study were Ficus roxburghii, Mallotus philippensis, Shorea robusta, Woodfordia fruticosa. The observed trend of dust accumulation was in the order Ficus roxburghii (38.30 mg m-2) > Shorea robusta (26.94 mg m-2),> Mallotus philippensis (22.31 mg m-2) > Woodfordia fruticosa (16.70 mg m-2). The present study revealed, that the leaf dust accumulation decreased with increasing distance from the national highway. Leaf dust accumulation was influenced by the seasons of the year with the maximum (30.70) in pre-monsoon and the minimum(21.42) in post-monsoon season. ER -
