Question

Major aerosol pollutant in jet plane emission is
(a)Sulfur dioxide
(b)carbon monoxide
(c)Methane
(d)Fluorocarbon

Answer 1

Hint: Emission of the pollutant from the jet plane is also related to the photochemical type of smog formation and is a major cause of depletion of the ozone layer. These are also used as refrigerants and air conditioners.

Complete step-by-step answer:
The main pollutant of concern around the airport is nitrogen dioxide emission from surface traffic and jet planes which result in damage to the stratospheric ozone layer. The most abundant of fluorocarbons emitted in the troposphere are CFC11 and CFC 12 which are not soluble in the water.

Additional Information: -Jet planes and car exhaust contain a variety of air pollution inclined sulfur dioxide and oxides of nitrogen.
-The mission of pollutants at higher altitudes is more responsible for climate change than the emission of those on the ground.
-The injection of H2O and HNO3 by the jet plane engines results in the formation of polar stratospheric clouds which could cause a significant role in ozone depletion.
-Chlorofluorocarbons are halocarbons that are nontoxic, the non-flammable chemical in nature which contains chlorine, carbon, fluorine.
-The chlorofluorocarbon under photolytic decomposition by UV radiation releases inorganic chlorine in the stratosphere.
-CFCs are used as a coolant in air conditioners and refrigerators because of their nontoxic nature and inert at low temperatures.
-CFCs are synthesized by the precursor to tetrafluoroethylene, the monomer that is converted into Teflon.

So, the correct answer is, ‘fluorocarbon.’

Note: -The pollution emission during a landing is greater than those during departure, this is because the time for landing is greater than the time of taking off.
-Hydrocarbon emission from fan jet engines is significantly greater in comparison to the emission from jet engines.
-Carbon monoxide and hydrocarbon amount in the exhaust products generally increased with decreasing engine power setting and nitrogen oxide amount increased with the increasing power of engine setting.
