The study represents the seasonal characteristics (carbonaceous aerosols and elements) and the contribution of prominent sources of PM and PM in the high altitude of the eastern Himalaya (Darjeeling) during August 2018-July 2019. Carbonaceous aerosols [organic carbon (OC), elemental carbon (EC), and water soluble organic carbon (WSOC)] and elements (Al, Fe, Ti, Cu, Zn, Mn, Cr, Ni, Mo, Cl, P, S, K, Zr, Pb, Na, Mg, Ca, and B) in PM and PM were analyzed to estimate their possible sources. The annual concentrations of PM and PM were computed as 37±12 μg m and 58±18 μg m, respectively. Read More
