  3. 3. AIR POLLUTION • Air pollution means degradation of the air quality harmfully affecting the living organisms as well as certain objects.
  4. 4. Particulate pollution
  5. 5. Gaseous pollution
  6. 6. Sources of pollution Natural sources • volcanoes • Storms Man-Made sources • automobiles • industries
  7. 7. Vehicular air pollution The exhausts given out contain three main gaseous pollutants: CO2,SO2 and CO.
  8. 8. Industrial air pollution The smoke released by the factory chimneys into the air contains lot of particulate pollutants
  9. 9. Burning garbage The smoke given out on burning garbage releases CO2 and some other harmful gases which adds to the particulate air pollution.
  10. 10. Brick kilns Brick kilns are fire-heated enclosures for making construction bricks. Lot of smoke and heat given out are pollutants.
  11. 11. Water pollution • Any change in the water quality which makes it unsuitable for use by humans and by other living organisms.

  14. 14. SEWAGE •
  15. 15. INDUSTRIAL WASTE
  16. 16. OIL SPILLS
  17. 17. THERMAL POLLUTION • Hot waste water released into nearby streams by industries cause thermal pollution affecting living organism.
  18. 18. SOIL POLLUTION • Soil contamination or soil pollution is caused by the presence of xenobiotic (human-made) chemicals or other alteration in the natural soil environment.
  19. 19. SOURCES
  20. 20. SOURCESIndustrial waste Urban commercial and domestic waste Chemical fertilizers Biomedical waste pesticides
  21. 21. Radiation • Radiation is a form of energy consisting high energy particles. It is extensively used in medical fields and generating electricity.
  22. 22. Chernobyl nuclear disaster
  23. 23. Noise pollution • Noise is defined as any disturbing sound.
  24. 24. Effects of noise pollution • Interferes in communication • Interrupts concentration of thought • Lowers efficiency • Disturbs sleeps • Irritability • Damage ear drum • Lead to deafness • Bird life gets disturbed
  25. 25. OTHER EFFECTS OF POLLUTION • Acid rain Acid rain is a rain or any other form of precipitation that is unusually acidic.
  26. 26. • Greenhouse effect and global warming Greenhouse are small houses specially constructed to grow plants. Global warming is continuing rise in the average temperature of Earth's climate system.
  27. 27. • Ozone layer depletion
