Definition of PollutionDefinition of Pollution Pollution is the introduction of elements of non-naturalPollution is the introduction of elements of non-natural components to the natural elements of the environment, or tocomponents to the natural elements of the environment, or to conduct resulting in normal waste, but in large quantities, thusconduct resulting in normal waste, but in large quantities, thus causing an imbalance in the ecological balancecausing an imbalance in the ecological balance

Definition of Air PollutionDefinition of Air Pollution AirAir PollutionPollution is an atmospheric condition in which certain substances like gases , Particulate matter , radioactive substances etc are present in concentrations which can cause undesirable effects on human environment AirAir PollutionPollution: Outdoor Air Pollution – Indoor Air Pollution
  • 8. CausesCauses ofof AirAir PollutionPollution The Main Causes of Air Pollution are  Natural Sources ( Volcanoes–Wildfires– Tornados etc )  Man Made Sources ( Factories – Automobiles – Energy Sources )
  • 9. Classification of pollutantsClassification of pollutants    PRIMARY POLLUTANTS The pollutants that are a direct result of the process can be called primary pollutants.  SECONDARY POLLUTANTS the ones that are caused by the inter mingling and reactions of primary pollutants. Smog created by the interactions of several primary pollutants is known to be as secondary pollutant.

Mexico City’s air has gone from among the world’s cleanest to among the dirtiest in the span of a generation , Historic air pollution episodes of the 1950s led to acute increases in infant mortality. Prior to the 1940s, Mexico City was known for its clear air and spectacular views of snow-capped volcanoes. Today, the city's mountains are only rarely visible due to some of the worst air pollution in the World. In 1992, the U.N. described Mexico city as being the city with the world’s worst air quality IntroductionIntroduction

  • 20. IntroductionIntroduction Around 3 billion people cook and heat in their homes using solid fuels (i.e. wood, charcoal, coal, dung, crop wastes) on open fires or traditional stoves. Such inefficient cooking and heating practices produce high levels of household (indoor) air pollution which includes a range of health damaging pollutants such as fine particles and carbon monoxide. In poorly ventilated dwellings, smoke in and around the home can exceed acceptable levels for fine particles 100-fold. Exposure is particularly high among women and young children, who spend the most time near the domestic hearth. According to WHO, 4.3 million people a year die from the exposure to household air pollution.
