The depositing of acidic particles or gases on a surface. Tiny aerosol particles, such as Sulfur and Nitrogen oxides emitted from a smoke stack, will remain suspended until they coagulate into bigger particles and settle (Dry deposition) or until they dissolve in water and are carried to the ground with rain (Wet deposition or Acid rain). Acid deposition has adverse effects on buildings, statuary, vegetation, lakes, and other outdoor surfaces.
