Dry deposition is defined as the deposition to land or water of particulate matter. Atmospheric deposition is a major process that removes pollutants from the atmosphere and an important source of nutrients and contaminants for ecosystems. Daily dry deposition flux and Total Suspended Particulates (TSPs) in the atmosphere were measured seasonally at 4 locations in Saraburi, Thailand in 2018.
The TSPs were collected using traditional Hi-Volume Air Sampler. Deposition fluxes were collected using dry deposition plates as introduced by Air Quality Laboratory, Illinois Institute of Technology, IL, U.S.A. Particulate deposited on the deposition plates and the filters from the Hi-Volume Air Sampler were analyzed for 16 trace metals using Digestion, Inductively Coupled Plasma Method. Dry deposition velocities (deposition flux/atmospheric concentration) for trace metals including Pb, Ag, As, Ba, Cd, Cr, Cu, Hg, Mn, Ni, Sb, Se, Sn, Tl, V and Ti were calculated. The results based on 2018 observations found that dry deposition plays a significant role in trace metals deposition in Saraburi, Thailand. The dry deposition velocities of 16 trace metals are 0.038, 0.042, 0.0022, 0.0018, 0.0089, 0.0097, 0.0021, 0.000136, 0.0278, 0.008, 0.0005, 0.000085, 0.000044, 0.763, 0.00153 and 0.0434 respectively
