  3. (in atmospheric chemistry) The removal of pollutants from the atmosphere by natural processes, including scavenging by cloud water, rainout and washout. This type of removal process is termed precipitation scavenging. Scavenging of airborne pollutants at the surfaces of plant, soil, etc., is termed dry deposition.
