Striving for better environment

Acid Rain:

  • Acid rain is rainwater containing harmful amounts of nitric and sulphuric acids.
  • When fossil fuels such as coal, wood, petroleum are burnt, nitrogen oxides and sulphuric oxides are released into the atmosphere.
  • These products are soluble in water.
  • During rains, these oxides react with large quantities of water vapour of atmosphere to form acids like sulphuric acid, nitric acid and nitrous acid.
  • These acids mix with mist, rainwater drops or snow and change it's composition.
  • The rain or snow that falls to the ground is called acid rain. 

Oil spills:

  • Accidental release of oil into a body of water as from a tanker, offshore drilling rig or underwater pipeline and wells, often present a hazard to marine life and the environment.
  • These oil spills form a layer in the sea and prevent sunlight penetrating the water, which harms the marine life.

Sources of Noise Pollution:

  • Road traffic noise.
  • Air craft noise.
  • Rail roads.
  • Construction noise.
  • Noise in industries.
  • Celebration of festivals.
  • Noise from consumer products.

E.g. Household appliances.

Sources of Radioactive Pollution:

  • Nuclear power plants.
  • Nuclear fuel.
  • Nuclear weapons.
