Final answer:
Benzene is the direct pollutant that results from fuel vapors escaping to the atmosphere or unburned fuel coming out of the tailpipes of a vehicle.
Step-by-step explanation:
These pollutants include toxic substances such as benzene, carbon monoxide, and nitrogen oxides (NOx), which are emitted from the combustion of fuels in vehicles. Benzene, for instance, is found in gasoline and is known to cause cancer and other health issues. Vehicle emissions also contribute to the formation of smog, which is a complex mixture of air pollutants. The utilization of a catalytic converter helps convert these toxic emissions into less harmful substances before they are released from the exhaust system into the atmosphere.The direct pollutant that results from fuel vapors escaping to the atmosphere or unburned fuel coming out of the tailpipes of the vehicle and is considered toxic is benzene.
Benzene is a primary pollutant found in gasoline, and it is known to be toxic and carcinogenic. It poses a serious health risk to humans and can cause cancer or other harmful health effects.
When gasoline is burned in a car engine, benzene is released into the air through the tailpipe. Breathing in benzene can have detrimental effects on human health, making it important to minimize its release into the atmosphere.
