Quizplus · Accepted Answer

Automobiles are the main source of anthropogenic carbon monoxide in urban areas as they emit exhaust that contains carbon monoxide. Coal burning is a significant source, but it is more prevalent in industrial areas rather than urban areas. Burning agricultural wastes and forests also release carbon monoxide, but it is not a primary source in urban areas. Unburned gasoline is also a source, but it is often a result of incomplete combustion in automobiles, making automobiles the main source overall.
