What is air pollution?

Air pollution can be defined as the processes of contaminating the atmosphere by the introduction of harmful toxic substances into it. These substances that brings about air pollution are called air pollutants. Air pollutants include smoke from the burning of petroleum products, coal, wood, rubber and plastics. Also, smoke from chimneys, industries and vehicles will attribute to air pollution. carbon(II)oxide (CO) is a gaseous pollutants that can lead to suffocation and death in animals. Sulphur(IV)oxide (SO2) and Nitrogen(IV)oxide (NO2) are also considered to be air pollutants. These gases will contribute to the formation of acid rain which will in turn destroy the leaves of plant. Certain normal processes like respiration, grassland fires and volcanic eruptions will also bring about air pollution. Reports suggest that air pollution kills over 2 millions people annually.

 

Effects of air pollution

  1. Eutrophication or Hypertrophication: a processes that brings about an increased growth of algae in water bodies which ultimately leads to the death of other aquatic organisms.
  2. It brings about the irritation of the eyes, nose and upper respiratory tract.
  3. It can cause cancer of the lungs and heart attacks
  4. Suffocation and death.
  5. Formation of acid rain and smog.
  6. It can cause the death of aquatic flora and fauna.
  7. Ozone layer depletion.
  8. Global warming.
  9. Green house effect.

 

Solutions to air pollution

  1. Afforestion (the planting of trees) should be highly encouraged.
  2. Solar, hydro-power and wind energies should be considered as alternative sources of energy.
  3. Alternatives to petroleum products should be used if possible. For example, water.
  4. Checks and maintenance of vehicles on road.
  5. Bush burning and residential burning should be highly prohibited.
  6. Industries should be locate far away from residential areas.
  7. Solid waste products should be properly managed.
  8. Use of improved and efficient coal mining techniques
  9. Improved use of nitrogen fertilizers

 

Note: Air pollution is one of the three major types of pollution. The other 2 are Land (soil) pollution and Water pollution.

Noise pollution, Light pollution and radioactive pollution are also types of pollution.
