Question

Cyclone collectors and electrostatic precipitators are meant for controlling
(a) Sewage pollution
(b) Air pollution
(c) Pesticide pollution
(d) Natural pollution

Answer 1

Hint: It is caused due to the particles present in the air which are harmful to the health of humans and others by causing damage to the climate and other materials. This will lead to various diseases and even allergies and the disease may even be so severe that it may lead to death.

Complete answer
The cyclone collectors are the devices through which the air pollutants can be removed from the air stream with the help of the vortex separation. It does not use the filters to remove the particulates from the air stream. The vortex separation is the method where the various gases that include the mixture of hydrogen and uranium hydrofluoride gas are injected inside the tubes and from the other tube the clean gas is separated out. While the electrostatic precipitators is a device which is issued to remove those particulate matters that are suspended in the air and are removed with the help of the application of the high voltage electrostatic charge that helps in collecting the dust particles on the charged plate. They both are the devices that are used to control the air pollution in the case of the industries.

Additional Information
-The U.S. Environmental Protection Agency (EPA) has approved and passed the Clean Air that was enacted to protect the surrounding and organisms from the harmful and toxic gases that are released into the air. This law was enacted in 1970 by the NRDC.
-The gases, smokes, and ash are the pollutants that are harmful to the environment as well as human health. The increase in these gases may result in an increase in the earth’s temperature thus resulting in global warming.
-he combination of hydrocarbons and nitrogen oxides when the sunlight is present will form the smog. These polluting gases will result in severe respiratory diseases.

So, the correct answer is ‘Air pollution’.

Note:
The vegetation plays an important positive role in atmospheric purification and air pollutants reduction of the atmospheric gases by photosynthesis, respiration processes, and the final stage of litter decomposition which is mineralization.
