MODEL RELEASED. Air pollution mask. Young girl wears a mask to protect her from air pollution. A cloudy blue sky is seen in the background. Cars and trucks are a major cause of invisible air pollution in towns and cities. Cars produce poisonous gases such as nitrogen oxide,sulphur oxide,carbon monoxide,unburnt hydrocarbons and lead fumes. Lead fumes may affect the mental development of children. A face mask like the one shown here can filter out the larger particles of soot and dust,but may not offer sufficient protection against other microscopic pollutants | |
