Veedustamine

Veedustamine is a term that appears in some environmental science discussions to describe processes by which dust particles are removed or transformed through contact with water. The word seems to be formed from the Estonian roots vee ("water") and dustamine ("dusting"), but it is not established in standard scientific nomenclature, and usage varies across sources.

In the proposed sense, veedustamine covers several mechanisms. Wet deposition occurs when precipitation scavenges airborne dust, reducing ambient particulate concentration and delivering material to the surface. Wetting and dissolution describe chemical alteration of dust constituents when particles interact with water, potentially changing solubility and mobility of metals and other elements. Mechanical washing refers to the physical removal of dust from surfaces by water flow, irrigation, or washing processes, which can modify surface texture and contamination levels.

Applications are mainly in environmental monitoring, industrial hygiene, and infrastructure maintenance. In air quality management, recognizing veedustamine-like processes can help distinguish between removal by rain and removal by deliberate washing or irrigation. Limitations include inconsistent usage and possible confusion with established terms like wet deposition, rainout, or washout. To avoid ambiguity, researchers should define the term clearly when used and specify the studied mechanism (deposition, dissolution, or washing).

Overall, veedustamine remains a niche, and its acceptance as a standard term varies. When used, it should be accompanied by a precise definition and context to prevent misinterpretation with related processes in hydrology and atmospheric science.
