Atmospheric Dry Deposition to Natural Water of Wetland in Suburban Beijing

Abstract

Particulate matter in the atmosphere may undergo many different aerodynamic processes, such as atmospheric dispersion, dry deposition and wet deposition [1]. Dry deposition is an extremely important process via which atmospheric trace chemicals are transferred by motion to the earth's surface [2]. In addition, it is an essential mechanism for removing pollutants from the atmosphere in the absence of precipitation [3]. In dry deposition, particulates are
