The type of hazardous pollution caused by automobile is ____

Explanation

Cars and automobiles produce carbon monoxide from burning gasoline. This happens when fuel does not burn completely in the engine, releasing dangerous gas through the exhaust.

Carbon monoxide is very poisonous and can kill people in enclosed spaces. It has no smell or color, making it especially dangerous because you cannot detect it.

While cars also produce carbon dioxide, carbon monoxide is the most hazardous pollution from automobiles. It is much more toxic and dangerous to human health.
