  • 4. POLLUTION
    • Pollution is an undesirable change in physical,chemical or biological characterstics of air,land or water that harmfully affected the life or create potential health hazard of living organism.
    • Any substance causes pollution is called pollutant.
  • 5. DIFFERENT TYPES OF POLLUTION
    • Air pollution
    • Water pollution
    • Soil pollution
    • Noise pollution
    • Radioactive pollution
  • 6. AIR POLLUTION
  • 7. Air pollution is the degradation of air quality and natural atmospheric conditions .
  • 8. RESULTS OF AIR POLLUTION
    • Air pollutants cause injury to all living organisms.
    • They reduce growth and yield of crops.
    • It cause premature death of plants
    • Affects respiratory system of human and of animals.
  • 9. PRIMARY AIR POLLUTANTS
    • Particulate matter
    • Carbon monoxide (CO)
    • Carbondioxide(CO2)
    • Volatile Organic Carbon (VOC) or Hydrocarbon (HC)
    • Sulphur dioxide(SO2)
    • Nitrogen oxide (NO2)
    • Fluorides
  • 10. 1.Particulate matter It comprises of solid particles or liquid droplets small enough to remain suspended in air. Eg : smokes,dust,pesticides,pollen, fungal spores ,fibres,some metal like copper, iron etc. EFFECTS -Injurious to health -asthma,tuberculosis,bronchitis etc .
  • 11. 2.Carbon monoxide (CO)
    • This poisonous gas is formed from partial combustion of fuels, steel industry, oil refiners,cigarettesmoke etc.
    • CO is very harmful to living organism especially to animals.
    • It inhibits cellular respiration in plants.
  • 12.
  • 13.
  • 14.
  • 15.
  • 16. 3.Carbondixide (CO2)
    • Due to the combustion of fuels, respiration process of plants and animals etc.
    • The main reason for increasing global warming is due to the present of high amount of CO2.
  • 17. 4. Volatile Organic Carbon (VOC) or Hydrocarbon (HC)
    • These are compounds of hydrogen and carbon.
    • Hydrocarbons are formed naturally during decomposition of organic matter and certain types of trees such as pine trees.
    • The chief source are the motor vehicle,burning of fuels,decay of garbage etc.

  • 21.
  • 22.
  • 23. 5. Sulphur dioxide (SO2)
    • SO2 is released from the combustion of sulphur containing coal, petroleum refining, automobiles, ore smelters etc.
    • High amount of sulphur dioxide destroys the vegetation.
    • It disappearance of chlorophyll and break down of cells.
  • 24.
  • 25. 6.Nitrogen oxide (NO2)
    • It form during combustion of fossil fuels as high temperatures in automobile engines.
    • It also released from power plants.
    • It may cause heart or lung problems and may be carcinogenic.
  • 26.
  • 27.
  • 28. 7. Fluorides
    • Hydrogen fluoride gas is an extremely phytotoxic gas released by the heating of fluoride rocks, soils etc.
  • 29. 8. Lead
    • Lead is emitted by automobile exhaust and it causes long-term environmental pollution.
    • Continuous inhaling of air borne lead pollution caused lead poisoning.
    • It reduces the oxygen carrying capacity of haemoglobin in the blood.
  • 30. SECONDARY POLLUTANTS
    • Photochemical smog
    • Acid rain
  • 31. 1.Photochemical smog
    • It is formed in traffic congested metropolitan cities where warm conditions and intense solar radiations are present.
    • It caused by combination of smoke and fog.
    • It cause series of health hazards.
    • Damage plant as well as animal life .
  • 32. 2.Acid rain
    • As a result of burning of fossil fuels, and petroleum, large quantities of sulphur oxide and nitrogen oxides reach the atmosphere
    • These gases oxidise into sulphuric acid and nitric acid.
    • It deposits on the surface of earth either through rain.
    • It changes the pH of the soil
