Question

Major aerosol pollutant in jet plane emission is
(A) Sulphur dioxide
(B) Carbon monoxide
(C) Methane
(D) Fluorocarbon

Answer 1

Hint: Jet plane emissions are the main sources of aerosol pollutants. The gases that are emitted from the jet planes interact with the atmosphere and to themselves. Some of these gases remain suspended in the air causing severe pollution and harmful effects.

Complete step by step answer:
Aerosols are defined as the small substances that are suspended in the atmosphere.For examples fog , mist, dust, forest exudates etc are the natural aerosols that remain suspended in the air. Where smoke is an example for man made or anthropogenic aerosols. Jet planes emit gases like sulphur dioxide, nitrogen oxides, hydrocarbons, lead, water vapour, and the black carbon.

Jet planes use fluorocarbon for the propulsion by which it emits large amounts of chloro fluoro hydrocarbons. These gases are emitted from the jet plane with the greater force in the form of water vapour. They are emitted to the maximum amount than the other which in term causes depletion of the ozone layer. Hence major aerosol pollutants that are emitted from the jet plane are fluorocarbons.

Thus, the option (D) is the correct one.

Note:
The Ozone layer is depleting nowadays due to the release of greenhouse gas. In term it causes global warming. Chlorofluorocarbon is the main greenhouse gas that causes ozone layer depletion. Depletion of the ozone layer causes direct entering of ultraviolet rays from the sun and causes global warming and also makes dangerous effects to humans.
