Car exhaust fumes. Fumes from a car exhaust belch out in front of an eight year- old girl and 3 year-old boy. The children are holding their hands over their mouths in order to avoid breathing in the fumes. 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.
