Pollution & India

  1. 1. Pollution is the introduction of contaminants into a natural environment that causes instability, disorder, harm or discomfort to the ecosystem i.e. physical systems or living organisms. Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the elements of pollution, can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point source or nonpoint source pollution. The Blacksmith Institute issues an annual list of the world's worst polluted places. In the 2007 issues the ten top nominees are located in Azerbaijan, China, India, Peru, Russia, Ukraine and Zambia.

The increasing economic development and a rapidly growing population that has taken the country from 300 million people in 1947 to more than one billion people today is putting a strain on the environment, infrastructure, and the country’s natural resources. Industrial pollution, soil erosion, deforestation, rapid industrialization, urbanization, and land degradation are all worsening problems. Overexploitation of the country's resources be it land or water and the industrialization process has resulted environmental degradation of resources. Environmental pollution is one of the most serious problems facing humanity and other life forms on our planet today. India's per capita carbon dioxide emissions were roughly 3,000 pounds (1,360 kilograms) in 2007, according to the study. That's small compared to China and the U.S., with 10,500 pounds (4,763 kilograms) and 42,500 pounds (19,278 kilograms) respectively that year. The study said that the European Union and Russia also have more emissions than India India has been ranked as seventh most environmentally hazardous country in the world by a new ranking released recently. The study is based on evaluation of “absolute” environment impact of 179 countries, whose data was available and has been done by researchers in Harvard, Princeton, Adelaide University and University of Singapore 0n January 12, 2011. Brazil was found to be worst on environmental indicators whereas Singapore was the best. United States was rated second worst and China was ranked third.

  3. 3. Soil contamination occurs when chemicals are released by spill or underground leakage. Among the most significant soil contaminants are hydrocarbons, heavy metals, MTBE, herbicides, pesticides and chlorinated hydrocarbons.
  4. 4. Causes of Soil Pollution We can classify major sources that lead to land following Categories O Mining and quarrying O Sewage waste O Household Garbage O Industrial Waste Home
  5. 5. Agricultural Land turns into barren Land. Ground water gets polluted. People will be porn to diseases. Hom
  6. 6. Prevention of Soil Pollution• More and more land should be brought under farming • Trees should be planted everywhere. • Avoid drilling the Land for more underground water. • Avoid using fertilizers and Pesticides Home
  7. 7. Home Water pollution, by the discharge of wastewater from commercial and industrial waste (intentionally or through spills) into surface waters; discharges of untreated domestic sewage, and chemical contaminants, such as chlorine, from treated sewage; release of waste and contaminants into surface runoff flowing to surface waters (including urban runoff and agricultural runoff, which may contain chemical fertilizers and pesticides); waste disposal and leaching into groundwater; eutrophication and littering.
  8. 8. Home Causes of water pollutionCauses diseases like Cholera, Malaria, Typhoid etc. Aquatic life gets destroyedCauses fresh water depletion Home
  9. 9.  Conserve water by turning off the tap when running water is not necessary. This helps prevent water shortages and reduces the amount of contaminated water that needs treatment.  Be careful about what you throw down your sink or toilet. Don’t throw paints, oils or other forms of litter down the drain.  Use environmentally household products, such as washing powder, household cleaning agents and toiletries.  Take great care not to overuse pesticides and fertilisers. This will prevent runoffs of the material into nearby water sources. By having more plants in your garden you are preventing fertiliser, pesticides and contaminated water from running off into nearby water sources.  Don’t throw litter into rivers, lakes or oceans. Help clean up any litter you see on beaches or in rivers and lakes, make sure it is safe to collect the litter and put it in a nearby dustbin. Home
  10. 10. Air pollution:- the release of chemicals and particulates into the atmosphere. Common gaseous pollutants include carbon monoxide, sulphur dioxide, chlorofluorocarbons (CFCs) and nitrogen oxides produced by industry and motor vehicles. Photochemical ozone and smog are created as nitrogen oxides and hydrocarbons react to sunlight. Particulate matter, or fine dust is characterized by their micrometre size PM10 to PM2.5. Home

  12. 12. Air pollution comes from both natural and man made sources. Though globally man made pollutants from  Combustion  Construction  Mining  Warfare  Motor vehicles Causes Air Pollution Home
  13. 13. Mechanical collectors (dust cyclones, multicyclones) Electrostatic precipitators An electrostatic precipitator (ESP), or electrostatic air cleaner is a particulate collection device that removes particles from a flowing gas (such as air) using the force of an induced electrostatic charge. Electrostatic precipitators are highly efficient filtration devices that minimally impede the flow of gases through the device, and can easily remove fine particulate matter such as dust and smoke from the air stream. Bag houses Designed to handle heavy dust loads, a dust collector consists of a blower, dust filter, a filter-cleaning system, and a dust receptacle or dust removal system (distinguished from air cleaners which utilize disposable filters to remove the dust). Particulate scrubbers Wet scrubber is a form of pollution control technology. The term describes a variety of devices that use pollutants from a furnace flue gas or from other gas streams. In a wet scrubber, the polluted gas stream is brought into contact with the scrubbing liquid, by spraying it with the liquid, by forcing it through a pool of liquid, or by some other contact method, so as to remove the pollutants Home

  15. 15. Effects of Noise Pollution  Hearing Impairment  High Blood Pressure  Uncontrollable Stress  Sleep Disturbance  Colour Blindness Home

  18. 18. Pollution control is a term used in environmental management. It means the control of emissions and effluents into air, water or soil. Without pollution control, the waste products from consumption, heating, agriculture, mining, manufacturing, t ransportation and other human activities, whether they accumulate or disperse, will degrade the environment. In the hierarchy of controls, pollution prevention and waste minimization are more desirable than pollution control. In the field of land development, low impact development is a similar technique for the prevention of urban runoff Home
