Atmospheric Deposition: Sampling Procedures, Analytical Methods, and Main Recent Findings from the Scientific Literature

Table 1

Mechanisms of aerosol deposition [2–5].

Wet deposition	Rain washout	Within a cloud	In-cloud scavenging or rainout, or droplets nucleation around particles
		Below a cloud	Droplets-particle collision
Dry deposition	Deposition processes which are not influenced by precipitation
Occult deposition	Water droplets deposited by the interception of fog, mist, or clouds that play a significant role only in the case of frequently cloud-covered zone, or by adjective fog, but are negligible in urban areas
