ABSTRACT
The US Environmental Protection Agency has criteria inorganic outdoor air pollutants as follows: carbon monoxide (CO), nitrogen dioxide, sulfur dioxide, ozone, lead, and suspended particulate matter, which have widely variable chemical compositions. Most studies have focused on neurological and cardiac effects related to acute high-level CO exposures, such as accidents in domestic and industrial settings or intentional harm. However, there are additional significant CO sources in the form of industrial emissions, tobacco smoke, and traffic-related air pollution, as well as indoor biomass burning, used extensively in developing countries as the primary domestic energy. Short-term effect of winter air pollution on respiratory health of asthmatic children in Paris, France was seen. The major local sources contributing to ambient air pollution in the Paris, France area are heating and automobile exhaust. Ozone is a specific air pollutant generated by photochemical reactions in the atmosphere and resulting from a combination of emissions of hydrocarbons, nitrogen oxides.
