Air pollution. Composite image representing air pollution, showing a child's face and a traffic jam. Motor vehicles are a major source of atmospheric pollutants, producing pois- onous gases such as nitrogen oxides, carbon monox- ide and ozone. They also emit unburnt hydrocarbons and microscopic particles of partially-burnt soot. Cars using leaded petrol give out lead fumes which affect children's mental development.
