  1. 1. DEPT OF COMMERCE
  2. 2. A IRP OLLUTION
  3. 3. A IR P OLLUTION Air pollution is perhaps the most common and the most dangerous type of pollution. It involves the direct release of chemicals into the environment. The chemicals then become the part of the air around us that all the living things take in.
  4. 4. W ATER P OLLUTION The 75% of the earth’s surface is covered with water and more that half of the total population of earth’s species resides in water. Moreover, our life greatly depends on water and life without water is impossible. Water pollution not only affects the fish and animals living in the water but also affects the whole food chain by also transferring the contaminants to the consumers depending on these animals.
  5. 5. N OISE P OLLUTION Unlike other the above mentioned types of pollutions does not involve hazardous chemicals or their incorporation into the environment, rather noise pollution is the increase in the rate of noise in the environment. Noise can be extremely dangerous. And it is all around us. It penetrates into human mind and controls it.
  6. 6. S OIL P OLLUTION Soil pollution involves the contamination of soil by the release of harmful substances into the soil. Unlike air pollution, which has a direct affect on human lives, soil pollution causes an indirect damage to humans and other animals.
  7. 7. W HY I S A IR P OLLUTION B AD ? Everybody even the children know that air pollution is bad but how it is bad and what effects it can bring to humans or to other aspects of the environment is a million dollar question. The whole story of air pollution revolves around the hazards that it is capable of causing to the atmosphere.
  8. 8. S OURCES Sources of air pollution refer to the various locations, activities or factors which are responsible for the releasing of pollutants into the atmosphere.
  9. 9. A NTHROPOGENIC SOURCES ( HUMAN ACTIVITY ) "Mobile Sources" include motor vehicles, marine vessels, aircraft and the effect of sound etc. Military, such as nuclear weapons, toxic gases, germ warfare and rocketry FROM FIRE THE FOREST. FROM USE OF Chemicals.
  10. 10. S OURCES AND M ETHODS BY HUMAN motor vehicle exhaust industrial processes auto manufacturing building demolition fuel production roadway construction
  11. 11. A IR POLLUTION IN INDIA Air pollution is high in Indian cities. Indian cities are polluted by vehicles and industry emissions. Road dust due to vehicles also contributing up to 33% of air pollution[12] In cities like Bangalore, around 50% of children suffer from asthma.[13] India has emission standard of Bharat Stage IV (Euro IV) for vehicles since 2005.
  12. 12. W HO; DATA ABOUT A IR P OLLUTION The World Health Organization estimates that about two million people die prematurely every year as a result of Air pollution , while many more suffer from breathing ailments, heart disease, lung infections and even cancer.
  13. 13. W ORLD DATA FOR AIR P OLLUTION
  14. 14. W HAT IS GLOBAL WARMING ? Global warming is when the earth heats up (the temperature rises). It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature.
  15. 15. WAYS YOU CAN REDUCE AIR POLLUTION ? Conserve energy - turn off appliances and lights when you leave the room. Recycle paper, plastic, glass bottles, cardboard, and aluminum cans. Plant deciduous trees in locations around your home to provide shade in the summer, but to allow light in the winter.
  16. 16. WAYS YOU CAN REDUCE AIR POLLUTION ? Connect your outdoor lights to a timer or use solar lighting. Wash clothes with warm or cold water instead of hot. Buy rechargeable batteries for devices used frequently. Choose efficient, low-polluting models of vehicles.
  17. 17. E FFECTS FROM A IR P OLLUTION  Global warming  Ozone depletion (Ozone hole)  Acid Rain
  18. 18. PLANT TREE TREE reduce the air pollution in the world. It also reduce the global warming. PLANT A TREE AND CONTRAL THE POLLUTION IT IS A GOOD SOCIAL WORK…
