Study of seasonal and spatial variations in leaf dust accumulation of selected tree species in the industrial area of Solan District of Himachal Pradesh

The total dust load of the tree species namely Azadirachta indica, Dalbergia sissoo and Leucaena leucocephala in the industrial area of Baddi was recorded during summers, monsoon and winters and at different distances from the industrial cluster. The dust load of selected tree species ranged from 0.018-0.045g m-2. The highest dust load was recorded in L. leucocephala followed by D. sissoo and A. indica.Seasonally the highest dust accumulation was recorded in winters (0.057 g m-2) and minimum in rainy season (0.013g m-2). Within distances the decrease in the leaf dust accumulation with increasing distance from the industries was also observed which ranged from 0.013-0.041 mg g-2.
