Car exhaust fumes. Dark fumes from a car exhaust belch out in front of two young children. Car engines produce a number of harmful gases such as nitrogen oxides and hydrocarbons from the incomplete combustion of fuel. This air pollution is implicated in a variety of respiratory problems in children, including the development of asthma.
