Air Pollution



What Is Air Pollution??

                Air pollution is the introduction of  chemiclas, particular matter, or biological materials that cause harm to discomfort to humans or other living organisms, or cause damage to the natural environment or built environment, into the atmosphere.

Types Of Air Pollution

  • There are several types of air pollution, mainly Indoor Air Pollution and Outdoor Air Pollution. These include smog, acid rain, the green house effect and hole in ozone layer.
  • One type of air pollution is the release of particles into the air.
  • Another type of air pollution is the release of poisonous gases. 

Outdoor Air Pollution

Smog

Smog is a type of large scale out pollution. It is caused by chemical reaction between pollutants derived from different sources.



Indoor Air Pollution

    It more dangerous than outdoor air pollution because we do everything in enclosed environment where air circulation may be restricted.

Sources of Indoor Air Pollution
  • Tobacco smoke 
  • Cooking and heating appliances
  • Vapoures from building materials

Acid Rain

  • It is caused when pollutant combines with droplets of water in the air.
  • The effects of acid rain on the environment can be serious.


Effects Of Acid Rain

  • Acid rain causes acidification of lakes and streams.
  • It contributes to the damage of trees and many sensitive forest soils.
  • It accelerates the decay of building materials and paint, including irreplaceable building, statues.


Hole In Ozone Layer

  • It is another result of air pollution.
  • Chemicals released by our activities affect the stratosphere.
  • Release of CFC from heating, aerosol cans, refrigerator equipments remove some of the ozone, causing “Holes”.

Causes Of Air Pollution

  • Dust raised on the ground during dust storms.
  • Stone dust raised by crushing of stones in quarries.
  • Smoke emitted by vehicles.
  • Smoke from forest fires.
  • Smoke raised by burning of coal in powerhouses.
  • Burning of wood, cow dung cakes, garbage etc. 

Preventions

  • Vehicle care
  • Public transport
  • Alternative energy sources
  • Saving energy
  • Minimize Air Pollution
  • Recyclable materials

  SAVE WATER SAVE LIFE Pollution of water   Domestic Pollution Safe water supply sanitation  - open defecation Drainage  Solid waste disposal  Agriculture Pollution  Pesticides Fertilizers  Over extraction of ground water Water and health The body is comprised of 72% of water.  we cannot live without water for more than 24 hours.  1.8 million people die from diarrhea death where 90% are children  88% is attributed to unsafe water supply, inadequate sanitation and hygiene.   Environment Don’t throw your household waste near drinking water sources Clean your house and surroundings daily Don’t throw paper, plastic, households wastes into open drains that run through the street Throw litter into a bin and dispose of it properly Don’t cut down trees but grow more plants See that the drains are not blocked Do you know? Flushing the toilet accounts for 30% of household water usage. By placing a brick in the toilet cistern we could save 10 million litres of water a day. Saving water starts

  GLOBAL WARMING   Introduction Global Warming is the increase in average temperature of the earths near surface air and oceans. Most of the observed temperature increase is caused by increase concentration of greenhouse gases.  Major gases                             water vapour     = 36-70%           carbon dioxide  = 9-26%           methane           = 4-9%           ozone               = 3-7% Causes of global warming Emission of green house gas like carbon dioxide, methane, nitrous oxide etc. The major source is carbon dioxide (80%). 20% by methane and nitrous oxide . Carbon dioxide The major source of carbon dioxide is the power plants. Burning of fossil fuels for the purpose of electricity generation . About 20% of carbon dioxide emitted in the atmosphere comes from burning of gasoline in engines of the vehicles.  Methane Methane is more than 20 times as effectual as carbon dioxide at entrapping heat in the atmosphere. Methane is obtained from resources such as rice padd
