1. AIR POLLUTION Kiran &Dippan

2. Air pollution is the introduction ofchemicals, particulate matter, orbiological materials that cause harm ordiscomfort to humans or other livingorganisms, or cause damage to thenatural environment or builtenvironment, into the atmosphere. 3. Gases that envelop the earth and are held here by gravityregulates temperature.MAJOR GASES 78% - Nitrogen 20.6% - Oxygen 0.934% - argon 0.035% - Carbon Dioxide Trace amounts water vapour (close to surface) 0.01% byvolume near poles to 5% near equator and many othershydrogen, neon, helium, Krypton, ozone and methane. 4. Composition of the Earths Atmosphere (Gases Percent by Volume)Others:-Argon 0.934%Water Vapour 0.4%Carbon Dioxide 0.035%Neon 0.00182%Helium 0.000524%Methane 0.00015%Krypton 0.000114%Hydrogen 0.00005%N20 0.00003%Ozone 0.000005%CFCs 0.0000001% 5. AIR QUALITY INDEXThe AQI is an "index" determined by calculating thedegree of pollution in the city or at the monitoringpoint and includes five main pollutants particulate matter ground-level ozone sulfur dioxidecarbon monoxide andnitrogen dioxide 6. aurae-beidler.suite101.com 7. Types ofAirpollutionINDOORAIR POLLUTION:SmokingStoveInsecticideCosmeticsCleaning Material 8. VehiclesFactoriesVolcanic Eruption etc. 9. DO YOU KNOW?Pollution exposure at home and workis often greater than outdoors. TheCalifornia Air Resources Boardestimates that indoor air pollutantlevels are 25-62% greater than outsidelevels and can pose serious healthproblems. 10. Air Pollutants categories :Two Broad Categories.a) Primary:Primary Pollutants are those released directly intothe air. Such as CO, NO2, SO2 etc.b) Secondary:Primary Pollutants are converted into othercompounds in atmosphere due to chemical reactionwith each other or photochemical reaction, e.g Smog,HNO3, SO3, O3. 11. NATURAL SOURCES:- Forest fires, Volcanic eruptions,wind erosion, pollen dispersal, evaporation of organiccompounds, and natural radioactivity. 12. HUMAN MADESOURCES Burning Fuels(Mobile or Stationary)Power PlantsFertilizersFumes from PaintHair Spray orperfumesVarnishCleaning Products 13. HAZARDOUS HEALTH EFFECTSShort-term effects include irritation to the eyes,nose and throat, and upper respiratory infections such asbronchitis and pneumonia. Other symptoms can includeheadaches, nausea, and allergic reactions. Short-term airpollution can aggravate the medical conditions ofindividuals with asthma and emphysema. In the great"Smog Disaster" in London in 1952, four thousand peopledied in a few days due to the high concentrations ofpollution. 14. Long-term health effects can includechronic respiratory disease, lung cancer,heart disease, and even damage to the brain,nerves, liver, or kidneys. Continual exposureto air pollution affects the lungs of growingchildren and may aggravate or complicatemedical conditions in the elderly. It isestimated that half a million people dieprematurely every year in the United States asa result of smoking cigarettes. 15. Negative impact on health:-Lung DamageSkin DiseaseHeart Problem etc. 16. Acc. To a case study the urban airquality over the city LUDHIANA isdeteriorating with time. Correctivemeasures need to be taken before itbecomes uncontrollable.in additionto the industrial and vehicularpollution, the agricultural pollutiondue to burning of wheat and ricestraw should be checked because italso creates tremendous pollution inthe atmosphere.Department of Agronomy, Agrometeorology andForestry, Punjab Agricultural University 17. Global WarmingGlobal warming is an increase in the temperature ofthe atmosphere near the Earths surface and in thetroposphere, which can contribute to changes inglobal climate patterns. 18. Acid RainAlso called acid precipitation or acid deposition, acid rainis precipitation containing harmful amounts of nitric andsulfuric acids formed primarily by sulphur dioxide andnitrogen oxides released into the atmosphere when fossilfuels are burned. 19. DRASTIC EFFECT OF ACID RAIN ONOUR FAVOURITE SYMBOL OF LOVETAJ MAHALBEFORE AFTER 20. SmogFog that has become mixed and polluted with smoke . Aform of air pollution produced by the photochemicalreaction of sunlight with hydrocarbons and nitrogen oxidesthat have been released into the atmosphere, especially byautomotive emissions. 21. Depletion of Ozone layerDestruction of ozone in the ozone layer attributed to thepresence of chlorine from manmade CFCs and other forces.The layer is thinning because ozone is being destroyed at afaster rate than it is being regenerated by natural forces. 22. HOW CAN WE HELP ? 23. USE SOLAR ENERGY 24. biofiltersBiofilters use living materials to degrade pollutantswhen imobilized in the biofilm. 25. DRIVING TOWARDS CLEANEREMISSIONS.CATALYTIC OXIDIZERS can be placedin the exhaust system of cars to reduceemissions from exhaust pipe. 26. Use safe Cars 27. BY SPREADING AWARENESS. 28. Plant more trees 29. HERES TOP 10 POLLUTED CITIESOF THE WORLD!AHWAZ, IRANULAN BATOR, MONGOLIASANADAJ, IRANLUDHIANA, INDIAQUETTA, PAKISTANKERMANSHAH, IRANPESHAWAR, PAKISTANGABERONE, BOTSWANAYASOUJ, IRANKANPUR, INDIA 30. Air Pollution in India (Acc. To WHO) Ludhiana:- Ranks as the most polluted city in India Kanpur:- Second most polluted city in India Delhi:- Ranks third Lucknow:- Ranks fourth Indore:- Ranks Fifth 31. Few amazing facts about Air Pollution Air pollution affects kids more than adults because, for their bodysize, kids breathe more air and spend more time playing outside. The health effects of smog have even been seen in dolphins living offthe coast of large cities. In a recent study, dolphins showed signs ofblack lung disease, an illness usually found among coal miners. More hazardous pollutants are discharged into the air each year thanare released to surface water, ground water, and land, combined. Walking and bicycling are great ways to exercise and reduce airpollution. Motor vehicles produce more air pollution than any other singlehuman activity. 32.
