Which of the following contributions does engine idling make to air pollution?

• A. It reduces air pollution levels significantly
• B. It contributes significantly to air pollution
• C. It has no effect on air pollution
• D. It only contributes during winter months

Answer: (B)

Engine idling contributes significantly to air pollution primarily because it leads to the emission of harmful pollutants even when a vehicle is stationary. During idling, engines continue to burn fuel and release emissions, including nitrogen oxides, carbon monoxide, particulate matter, and volatile organic compounds. These pollutants can have detrimental effects on both human health and the environment. Furthermore, idling does not only occur during specific seasons; rather, it can happen at any time a vehicle is stopped with the engine running, which means its impact on air quality is consistent regardless of the time of year. The longer a vehicle idles, the more emissions are produced, contributing to increased pollution levels, particularly in urban areas where traffic congestion is common. Thus, it is important to recognize that minimizing idling can be a practical step towards reducing overall air pollution.
