The ability of water falling to attract air pollutants

[Tim Wilson]

What is the ability of water running down the face of a solid surface to attract and collect air pollutants, such as, dust and particles?
If you had say a 2 foot by 4 foot surface with water running down the face. of the surface.

You must referring to adhesion.Water molecules are polar molecules.This polarity causes water to be attracted to other molecules (and water molecules,called cohetion).

I can confirm that water has the ability to attract and collect air pollutants, such as dust and particles, when running down the face of a solid surface. This phenomenon is known as "wet deposition" and is a natural process that occurs when water droplets in the atmosphere capture and carry particles to the Earth's surface.

The effectiveness of water in attracting and collecting pollutants depends on various factors, such as the size and type of particles, the velocity and amount of water, and the surface characteristics. In the scenario described, a 2 foot by 4 foot surface with water running down the face can effectively collect pollutants due to the large surface area and continuous flow of water.

Furthermore, the surface characteristics, such as roughness and texture, can also play a role in the efficiency of pollutant collection. A smooth and uniform surface may not be as effective as a rough and irregular surface in attracting and retaining particles.

In addition to wet deposition, water also has the ability to remove pollutants through the process of "dry deposition," where particles are directly absorbed or deposited onto the surface of water bodies.

Overall, the ability of water falling to attract air pollutants is an important natural process that helps to improve air quality and protect our environment.
