Correct statement: Sulphur dioxide is the main pollutant emitted from the exhaust of petrol driven automobiles.
Explanation:
The incorrect statement is option C, which states that sulphur dioxide is the main pollutant emitted from the exhaust of petrol-driven automobiles. This statement is incorrect because sulphur dioxide is not the main pollutant emitted from the exhaust of petrol-driven automobiles.
Why is option C wrong?
1. Sulphur dioxide (SO2) is primarily emitted from the burning of fossil fuels, such as coal and oil, which are rich in sulphur. Petrol, on the other hand, contains very low levels of sulphur.
2. Petrol-driven automobiles primarily emit pollutants such as carbon monoxide (CO), nitrogen oxides (NOx), volatile organic compounds (VOCs), and particulate matter (PM).
3. Carbon monoxide (CO) is a colorless and odorless gas that is emitted from the incomplete combustion of fossil fuels, including gasoline used in automobiles. It is a poisonous gas that can be harmful to living organisms, including humans, when inhaled in high concentrations.
4. Nitrogen oxides (NOx) are formed during the combustion process when nitrogen in the air reacts with oxygen at high temperatures. These pollutants contribute to the formation of smog and acid rain and can have detrimental effects on human health.
5. Volatile organic compounds (VOCs) are emitted from the evaporation of fuel and other chemical compounds. They contribute to the formation of ground-level ozone, a major component of smog, and can have harmful effects on respiratory health.
6. Particulate matter (PM) refers to tiny particles suspended in the air, which can be emitted from the exhaust of vehicles. These particles can be harmful when inhaled, especially the smaller particles that can penetrate deep into the lungs.
Conclusion:
Sulphur dioxide is not the main pollutant emitted from the exhaust of petrol-driven automobiles. Instead, pollutants such as carbon monoxide, nitrogen oxides, volatile organic compounds, and particulate matter are the major pollutants emitted from the exhaust of petrol-driven automobiles.
