  6. 6. POLLUTION<br />Harmful Substances Contaminating the Environment is Called Pollution.<br />Refers to the very bad condition of environment in terms of quantity and quality . <br />
  7. 7. Types of Pollution<br />Air Pollution<br />Water Pollution<br />Noise Pollution<br />Land Pollution<br />Radio Active Pollution<br />Solid waste pollution<br />Thermal Pollution<br />
  8. 8.
  9. 9. Causes of air pollution<br />Major sources of Air Pollution<br /> - Industries<br /> -Automobiles and Domestic fuels<br /> -High Proportion of undesirable <br />gases, such as sulphur dioxide and carbon monoxide<br />
  10. 10. Effects<br />Air Pollution affects???<br />Human health<br />Animals <br />Plants<br />The atmosphere as a whole<br />
  11. 11. How to Avoid Air Pollution<br />Yes, we can avoid pollution As Follows<br />Use natural Gases, like lpg autos<br />Do not Burst Crackers<br />Use less Amount of Fuel for Vehicles<br />Avoid using and use electric stoves<br />(bio gas)‏<br />
  12. 12. Water Pollution<br />The Contamination of water with <br /> undesirable substances which make it unfit for usage is termed water Pollution.<br />
  13. 13. Water Pollution<br />
  14. 14. Effects<br />Diseases like Cholera<br />Malaria<br />Typhoid (spread during the rainy season )‏<br />Aquatic life gets destroyed<br />
  15. 15. How to Avoid Water Pollution<br />Rivers should not be used for washing clothes or bathing animals in.<br />Harvesting of Rainwater to meet water requirements.<br />Dams &embankments must be created.<br />The rivers must not be contaminated.<br />In sacred river like Ganga the dead bodies shouldn’t thrown.<br />
  16. 16. Causes <br />Traffic Noise<br />Air craft Noise<br />Noise from construction and civil engineering works.<br />Noise from the Industries.<br />Noise from other sources.<br />
  17. 17. See what is this?<br />Picture shows : Noise Pollution<br />
  18. 18. Effects <br />Hearing Loss<br />High Blood Pressure<br />Stress<br />Sleep Disturbance<br />Color Blindness<br />
  19. 19. How to Avoid Noise Pollution<br />The Government should ensure the new machines that Should be noise proof.<br />Air ports must be away from residential area.<br />The Sound horn symbol is to be in School Roads.<br />
  20. 20. Prevention<br />Pleasant Home<br />Bhagavan Baba says “Silent is God”.<br />We need to talk sweetly to others.<br />Talk Less Work More.<br />Sound affects our ears so loud noise should be avoided.<br />
  21. 21. Land Pollution<br />One fourth of area is covered by land is Called Land.<br />Land is a earth which is occupied by people for shelter,occuption etc..,<br />
  22. 22. Causes<br />We can classify major sources that lead to land following Categories<br />Mining and quarrying<br />Sewage waste<br />Household Garbage<br />Industrial Waste<br />
  23. 23. Land pollution pictures<br />
  24. 24. Effects<br />The Land Cannot be construct house<br />Man cannot be farming<br />Ground water will gets Affected<br />House hold Garbage like putting Plastics <br />
  25. 25. Prevention of Land Pollution<br />More and more land should be brought under farming<br />Trees should be planted everywhere.<br />Waste matter should be disposed immediately<br />Avoid drilling the Land for more underground water.<br />Avoid using more fertilizers and Pesticides.<br />
  26. 26. Radio Active Pollution<br />Despite the Advantage of nuclear as a clean energy, the big concern is the resulted from nuclear reaction, which is a form of pollution called Radio activity.<br />Radiation (Laser-Rays) will from Radio Active Pollution.<br />
  27. 27. Causes<br />Nuclear power plants(Ex:Neyveli,Kalpakkam)‏<br />Nuclear Weapon(Ex:Missiles)‏<br />Disposal of Nuclear Waste<br />Uranium Mining<br />
  28. 28. Effects of Radio Active Pollution<br />The Diseases include blood in cough<br />Ulcer<br />Swelling of bone joints<br />Cancer<br />Lung Cancer<br />Skin Cancer<br />Bone Cancer<br />Eye Problems<br />
  29. 29. How to Prevent of Radio Active Pollution<br />Avoid Constructing Nuclear Power Plants<br />Avoid Using Nuclear Weapon<br />Have Proper Treatment for Nuclear Waste<br />Avoid mining for Uranium to a minimal<br />
  30. 30. Solid Waste Pollution <br />Solid waste is that material which arises from various human activities and is normally discarded as useless or unwanted. It consists of discarded materials from the urban community as well as accumulation of agriculture, industrial, and mining wastes<br />
  31. 31. Classification: <br />Solid waste can be classified on the basis of content or moisture basis or on the <br />basis of heating value. <br />A typical classification is <br /> Garbage<br /> Rubbish <br /> Pathological waste <br /> Industrial waste<br />Agricultural waste <br />
  32. 32. Environmental Pollution Effects on HumansAir pollution <br />Reduced lung functioning <br />Irritation of eyes, nose, mouth and throat <br />Asthma attacks <br />Respiratory symptoms such as coughing and wheezing <br />Increased respiratory disease such as bronchitis <br />Reduced energy levels <br />Headaches and dizziness <br />Disruption of endocrine, reproductive and immune systems <br />Neurobehavioral disorders <br />Cardiovascular problems <br />Cancer <br />Premature death <br />
  33. 33. Classes of Pollutants And Ecological Effects<br />

  36. 36. Water pollution <br />Waterborne diseases caused by polluted beach water: <br />Rashes, ear ache, pink eye <br />Respiratory infections <br />Hepatitis, encephalitis, gastroenteritis, diarrhoea, vomiting, and stomach aches <br />Waterborne diseases caused by polluted drinking water: <br />Typhoid <br />Amoebiasis<br />Giardiasis<br />Ascariasis<br />Hookworm <br />
  37. 37. Soil contamination <br />Causes cancers including leukaemia <br />Lead in soil is especially hazardous for young children causing developmental damage to the brain <br />Also causes headaches, nausea, fatigue, eye irritation and skin rash <br />Mercury can increase the risk of kidney damage; cyclodienes can lead to liver toxicity <br />Causes neuromuscular blockage as well as depression of the central nervous system <br />
  38. 38. Environmental Pollution Effects on Trees and Plants <br />Air Pollution <br />Acid rain can kill trees, destroy the leaves of plants, can infiltrate soil by making it unsuitable for purposes of nutrition and habitation <br />
  39. 39. Water Pollution <br />Terrestrial and aquatic plants may absorb pollutants from water (as their main nutrient source) and pass them up the food chain to consumer animals and humans <br />Plants may be killed by too much sodium chloride (ordinary slat) in water <br />
  40. 40. Soil Contamination <br />May alter plant metabolism and reduce crop yields <br />Trees and plants may absorb soil contaminants and pass them up the food chain <br />
  41. 41. Environmental Pollution Effects on Wider Environment <br />Apart from destroying the aquatic life in lakes and streams, acid rain can also corrode metals, damage surfaces of buildings and monuments, and cause soil acidification. <br />Pollution of water may cause oxygen depletion in marine environments and severely affect the health of whole ecosystems.<br />
  42. 42. How can we control environmental pollution?<br />. <br />Green investment provides a great platform to explore and develop new and clean sources of energy such as solar electricity. <br />Building your own solar panels and using solar energy systems to meet at least part of your home electricity needs is another emerging opportunity for enthusiasts. <br />
