Question

The non-viable particulate is-
A.Bacteria
B. Mould
C.Fungi
D.Dust

Answer 1

Hint: Particulate matter is actually a particulate pollutant that causes air pollution. Particulate matter is present in the air is mainly of two types-Viable particles and nonviable particles.

Complete step by step answer:
Particulate matter can easily penetrate deep into the lungs and bloodstream of humans unfiltered. It causes the deadliest type of air pollution. It can vary in shape, size and composition. It is of two types-
1.Viable particulate matter-The viable particulate are the particles that include one-or more living microorganisms like- algae, fungi, bacteria, molds. They are dispersed in the air and can go inside the body of humans unfiltered. They cause allergies in human beings. They can also cause diseases in plants and animals.
2.Non-Viable Particulate matter-A non-viable particulate does not contain living organisms but it acts as a transport for viable particulate matter. These particles are smoke, dust, mist, fumes. They vary on the basis of size and nature.
The particulate matters originate from factories, power stations, incinerators, automobiles and diesel generators. Some even undergo complex chemical reactions in the atmosphere with the gases released from factories, industries or power plants.
Hence dust is the non-viable particulate.

So the correct answer is D.

Note:
A particulate pollutants is very dangerous for human , animals and plants alike.The effects of Particulate matters are –
-The fine particles can cause lung cancer , asthma, cardiovascular problems, due to arteries and vascular inflammation.
-They can cause birth defects and failed pregnancy due to long exposure to particulate matters.
-It is disturbing the environmental balance due to the rise in the number of particulate pollution.
-It causes decrease in rainfall and is the reason for droughts in particularly polluted areas.
