Environmental Pollution

Environmental Pollution

1. Pollution

   • The addition of undesirable material into the environment as a result of human activities. There are six types.
     • Air Pollution
       • The presence of any solid, liquid or gaseous substance including noise and radioactive radiation in the atmosphere that may be injurious to living organisms
         • Pollutants
           • Suspended particulate matter
             • Smoke from domestic, industrial and vehicular soot
           • Gaseous Pollutants
             • Part of smoke released from chimneys of factories and power plants
           • Prevention
             • Usage of cleaner sources like biogas.
             • Use devices of that reduce release of pollutants
             • Employing environmental friendly industrial processes
     • Noise Pollution
       • An irritant sound that is unvalued and unwanted by the recipient
         • Indoor sources
           • Noise produced by radio, TV, electric fans, air coolers, even family conflict
         • Outdoor sources
           • Indiscriminate use of loudspeakers, automobiles, rail traffic, aeroplanes and public activities.
         • Prevention
           • Better designing and proper maintenance of vehicles
           • Green belt of trees absorbs noise
           • Sound proofing equipment like generators
     • Water Pollution
       • Addition of undesirable substances in water
         • Sources
           • Pesticides and fertilisers used in agriculture
           • Oil pollution from leakage from ships, oil tankers, etc,
           • Discharge of domestic waste
           • Prevention
             • Sewage may be treated to make it safe for disposal
             • Usage of eco-friendly dishwashers
             • Recycling waste water for certain uses wit or with our treatment
     • Soil Pollution
       • Addition of substances which the quality of soil or its fertility
         • Sources
           • Plastic Bags made from low density polyethylene
           • Fly ash, chemical residues and nuclear wastes
           • Fertilizers and pesticides
           • Prevention
             • Indiscriminate disposal of solid waste should be avoided
             • Stop the use of plastic bags
             • Sewage should be treated properly before being used
     • Thermal Pollution
       • Discharge of hot water to water bodies
         • Sources
           • Waste heat from boilers and heating processes
           • Coal water plants
           • Waste heat from power plants
           • Prevention
             • Allow the water to cool before releasing it into any water bodies.
     • Radiation Pollution
       • Increase in over the natural background radiation
         • Sources
           • Nuclear wastes from nuclear power plants
           • Radioactive minerals
           • Cosmic rays
           • Prevention
             • Banning of nuclear tests
             • Perfect maintenance of nuclear reactors
             • Care should be taken to check manmade radiation pollution at source

2. Pollutants

   • Agents that cause environmental pollution. They can be physical, biological or chemical substances unintentionally released into the environment with is harmful to humans and other living organisms
