Question

The viable particulate among the following
A.Fumes
B.Algae
C.Smoke
D.Mist

Answer 1

The viable particulate is the particle that contains one or more living organisms. Generally,size ranges from ~0.2 to 30 micrometres in size.

Complete step by step answer:
Let us start with an option no a) fumes it is a gas or vapour that smells strongly and dangerous and fumes don't have any living organism, therefore, fumes are non-viable particulate.
Now, option b) algae they are the diverse group of aquatic organisms. They grow near the water. Therefore, algae are the living organism. Hence, they are viable particulates.
Let say about option c) smoke they are the collection of airborne particulates when the material undergoes combustion or pyrolysis. They don't have any kind of living organism, therefore they are non-viable particulate.
Now the last option, option d) mist it is phenomena caused by small droplets of water suspended in the air. It is an example of dispersion. As there is an absence of living organisms. Therefore, the mist is non – viable particulate.
Thus, the correct option is B.

Additional information: A distinct type of monitoring methods are used for viable particle detecting, such as.
-Passive air sampling (settle plate method)
-Active air sampling (volumetric air sampling)
-Surface monitoring (swap sampling)
-Personal monitoring (contact method)

Note:
A non-viable particle is a particle that doesn't contain a living organism but acts as transportation of viable constituents. Viable particles are not free-floating; they need carriers to float from one area to another area.
