Chapter 2 The Dispersion, Deposition and Resuspension of Atmospheric Contamination in the Outdoor Urban Environment

摘要: Publisher Summary This chapter discusses the dispersion, deposition, and resuspension of material in urban environment, along with physical factors that can affect these processes. Dispersion is dilution process occurs when transported downwind from a source it important determining atmospheric concentration. In turn, concentration inhalation dose. Deposition results surface uptake material. It an consideration estimating plume depletion potential for transport. also external radiation The deposition occur by its direct interaction or incorporation into precipitation. addition, fog this comprises mechanisms apparent both wet dry Once deposited, contaminants become airborne again because various mechanical effects.
