  • 1. Definition. Types Of Pollution. Causes. Effects.
  • 2.  Pollution is the introduction of contaminants into the natural environment that cause adverse change, in the form of killing of life ,toxicity of environment , damage to ecosystem and aesthetics of our surrounding .
  • 3. Air Pollution. Water Pollution. Noise Pollution. Soil Pollution Radioactive Pollution
  • 4.  Air pollution is contamination of the indoor or outdoor environment by any chemical, physical or biological agent that modifies the natural characteristics of the atmosphere.
  • 5.  Motor vehicles.  Household combustion devices.  Industrial facilities.  Forest fires
  • 6. • Maintaining a healthy distance between the industrial and residential areas. • The sulphur must be removed after burning. • The gasoline must have anti knocking agents. • The mining area should be planted with trees.
  • 7. • The coal fuel should be replaced with gas fuel to control the air pollution. • The automobiles must be designed with emission control system. • The wastes must be removed and recycled in the industrial plants and refineries. • Plants like pine and ribes need to be planted to metabolize the nitrogen oxides and other pollutants.
  • 8. • Timely servicing of the car helps to keep it in a good condition, and also minimizes fuel exhaustion. • Using public transportation helps to prevent the air pollution. • Using alternative energy sources like solar energy, hydroelectric energy, and wind energy.
  • 9.  Water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans, aquifers and groundwater).  Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds.
  • 10.  Water pollution affects plants and organisms living in these bodies of water. In almost all cases the effect is damaging not only to individual species and populations, but also to the natural biological communities
  • 11. Plastics Pesticides Heavy metals Sewage Radioactive waste
  • 12. Detergents Food processing waste  Insecticides and herbicides. Petroleum hydrocarbons, (gasoline, diesel fuel, jet fuels, and fuel oil). Lubricants (motor oil).
  • 13.  Conserve water by turning off the tap.  Don’t throw paints and oils in water channels.  Use environment friendly household products, such as washing powder, household cleaning agents etc.  Take great care not to overuse pesticides and fertilizers.
  • 14.  Noise pollution is displeasing or excessive noise that may disrupt the activity or balance of human or animal life.  Noise means disgust or discomfort hearing from environment.
  • 15.  Machines.  Transportation systems.  Motor vehicles.  Aircrafts.  Trains.  Poor urban planning.
  • 16.  Noise pollution affects both health and behavior.  Unwanted sound (noise) can damage psychological health.  Hypertension .  High stress levels .  Hearing loss.  Sleep disturbances, and other harmful effects.
  • 17. •Use of horns with jarring sounds, motorbikes with damaged exhaust pipes, noisy trucks to be banned. •Noise producing industries, airports, bus and transport terminals and railway stations to sighted far from where living places. •Community law enforcers should check the misuse of loudspeakers, worshipers, outdoor parties and discos, as well as public announcements systems.
  • 18. •Vegetation (trees) along roads and in residential areas is a good way to reduce noise pollution as they absorb sound.
  • 19.  Soil pollution is caused by the presence of chemicals or other alteration in the natural soil environment.  It is typically caused by industrial activity.  Agricultural chemicals.  Improper disposal of waste.
  • 20. • Limit the use of fertilizers and pesticides • Awareness about biological control methods and their implementation • The grazing must be controlled and forest management should be done properly • The afforestation and reforestation must take place • Proper preventive methods like shields should be used in areas of wind erosion and wind breaks
  • 21. Treating Wastes of industries. Treating nuclear waste. Proper disposing of plastics and other garbage materials.
  • 22.  Radioactive pollution is the presence of radioactive substances on surfaces or within solids, liquids or gases (including the human body), where their presence is undesirable
  • 23.  Radioactive Pollution may occur from radioactive gases, liquids or particles. For example, if a radionuclide used in nuclear medicine is spilled (accidentally or through ignorance), the material could be spread by people as they walk around.
  • 24.  The first effects were noted in the early 20th century. The people who were working in the uranium mines suffer from skin burn and cancer. These occur due to the radiations from the radioactive material.
  • 25.  The radioactive pollution can be controlled by number of ways. It includes the stoppage of leakage from the radioactive materials including the nuclear reactors, industries and laboratories.  The disposal of radioactive material must be safe and secure. They must be stored in the safe places and must be changed into harmless form.  The protective garments must be worn by the workers who work in the nuclear plants.
