  1. AIR POLLUTION

  2. What is AIR POLLUTION? • AIR POLLUTION affects many aspect such as; • Health • Environment • Destroys living organisms • Economic status

  3. short-term or long-term adverse effect. Based on research; • Around 3 billion people cook and heat their homes using open fires and leaky stoves burning biomass (wood, animal dung and crop waste) and coal. • Nearly 2 million people die prematurely from illness attributable to indoor air pollution from household solid fuel use. • Nearly 50% of pneumonia deaths among children under five are due to particulate matter inhaled from indoor air pollution. • More than 1 million people a year die from chronic obstructive respiratory disease (COPD) that develops due to exposure to such indoor air pollution. • Both women and men exposed to heavy indoor smoke are 2-3 times more likely to develop COPD.

  4. Causes of air pollution • Toxic Organic • Micro-Pollutants • SULFUR DIOXIDE • NITROGEN OXIDES • VOCs or VOSs • CARBON MONOXIDES • Benzene • FINE PARTICLES • Butadiene • OZONE AND VOLATILE • ORGANIC COMPOUNDS • Lead and Heavy Metals

  5. PRIMARY MECHANISM OF AIR POLLUTION • Formation of VOC through evaporation and incomplete combustion. • Biological generation of VOC. • Formation of liquid aerosol droplets through shear and turbulence related processes, from cooking and household solvent based cleaners. • Anthropomorphic generation of particulate aerosol.

  6. Biological formation of particulate aerosols through decomposition and spore formation. • Particulate aerosol floral and weather based phenomenamation from geologic. SECONDARY MECHANISM OF AIR POLLUTION • Condensation -- Liquid aerosol droplet formation due to condensation of gaseous phase components.

  7. Adsorption -- Adsorption of gaseous phase and liquid aerosol components onto particulate surfaces, resulting in particulate aerosols with modified surfaces from adsorption of organic compounds and hydrous inorganic phases. • Nucleation -- Liquid aerosol formation through precipitation onto micro particulate nucleation sites.

  8. EFFECTS OF AIR POLLUTION Along with harming human health, air pollution can cause a variety of environmental effects: • Acid rain • EUTROPHICATION • Haze • Effects on wildlife. • Ozone depletion. • Crop and forest damage • Global climate change.

  9. AIR POLLUTION IMPACTS TO ENVIRONMENT AND PEOPLE:

  10. MITIGATION OF AIR POLLUTION • AIR POLLUTION CONTROL ACT OF 1995 was the first United States Clean Air Act enacted by Congress to address the national environment problem of air pollution on July 14, 1995.

  11. CONCLUSION AND RECOMMENDATION • Air Pollution is not a huge problem for every country if we are responsible for our • own acts. • Air pollution can trigger us into danger, especially our health and environment.

  12. FIVE STEPS TO CLEAN UP: 1.Clean up coal-fired power plant 2. Strengthen ozone air standards voluntarily 3. Clean up oceangoing vessels 4. Improve the pollution-monitoring network 5. Enforce the law
