      odd–even formula  is a method of rationing in which access to some resource is restricted to half the population on any given day.  In a common example, private vehicles may be allowed to drive, park, or purchase gasoline on alternating days, according to whether the last digit in their license plate is even or odd. Similarly odd-even scheme, during a drought, houses can be restricted from using water outdoors according to the parity of the house number.

    Typically a day is “odd” or “even” depending on the day of the month. An issue with this approach is that two “odd” days in a row occur whenever a month ends on an odd-numbered day. Sometimes odd or even may be based on day of the week, with Sundays excluded or included for everyone The Capital can expect a rerun of the odd-even scheme car restriction the next time pollution levels cross the “severe” mark of 300 micro grams of PM 2.5 , micro particles of dust known to cause lung and respiratory diseases. The radical formula was tried before for two fortnights last January and April, restricting vehicles from roads on odd and even dates based on the last number of their licence plates.

Regardless of whether we need to concede or even consider it,  odd-even formula air contamination is a genuine issue, one that keeps on influencing our condition and our carries on with every single day. In spite of the fact that individuals who live in rustic zones can without much of a stretch overlook that such a difficult exists (as they don’t see brown haze and processing plants consistently) or recollect its causes (less vehicles on the streets), it is an undeniable issue that influences everyone. On occasion we can’t overlook this contamination. For instance, when driving past an industrial facility siphoning smoke mists high into the sky, or when remaining in a gridlock smelling the fumes of the vehicle before us, it is hard not to envision what harm it is never helping to body.

Air Pollution

    Air pollution is the world’s deadliest environmental problem. It kills 7 million people each year, or one in eight deaths globally. 4.3 million of these deaths are due to 2.8 billion people in the developing world who cook and keep warm inside their homes, by burning dung, firewood and coal – filling their living spaces with smoke and pollutants. Indoor air pollution from cooking and heating with open fires is equivalent to smoking two packets of cigarettes a day.

    How do we best address this problem?  For outdoor air pollution, the problem is even more difficult. Globally, reaching the WHO’s targets for air pollution, through low-sulfur diesel and car filters is too expensive relative to the benefit. In the focus area of air pollution, the best target is: .

Why is air pollution dangerous?

 Health reasons: pollution has been linked to numerous types of illnesses such as strokes, heart issues and breathing problems.

Global warming: air pollution is responsible for global warming. This phenomena leads to the gradual but persistent increase of the temperature of our planet. It has already started affecting entire ecosystems, and unless it is stopped, it will melt the polar ice caps which will raise sea levels. This will cause flooding in coastal cities such as New York and London.

Ozone layer: air pollution causes the ozone layer to shrink, thus, reducing its ability to shield us from ultraviolet radiation. This not only causes skin cancer, but also damages wildlife and plants.

Acid rain: certain pollutants can cause rain to turn to acid rain. This has a great impact on animals, fish and plants that are soaked in it. Acid rain can also affect the ground, making the soil toxic to many animals and plants.


          Whether the memory of the odd-even experiment will inspire us to lead healthier lives depends on the willingness of the so-called inspirational  classes to engage in a deeper debate on development It will take time and expertise to  this. odd-even experiment in Delhi, but there is no doubt that it was educative. It taught the government that the public is now ready to support radical measures on  air pollution. The public learnt that cynicism is not the only response to a hopeless situation. The odd-even fortnight is now a pleasant memory, but will it also be an inspiring one? The answer depends on the so-called inspirational classes. More specifically, it depends on their willingness to engage in a deeper debate on the meaning of development. It is said that the last few elections have been fought on the development agenda. That is hardly true, as there was barely any distinction between the contending political parties on their perspective on development. Since the 1990’s, development has meant the same thing to every political party. The images leaders evoke to refer to a developed India are identical and have been internalized by the public: they are of high-rises, shopping malls, expressways and flyovers. These are the familiar images of the West, especially the U.S. The fact that China has adopted them as symbols of its own development inspires many in India to do the same.  

Air contamination is such convergence of strong, fluid or vaporous substance including clamor and scent that may make impedance of well being or uneasiness living animals including individual, plant, property or condition. There are guidelines that determine allowable constraint of centralization of distinguished poisons in the air.

The environment is a skimming stockpiling of gases and water fumes. We acquired an environment made by the nature. This climate with careful amount of oxygen, nitrogen and Carbon dioxide is our life line. Of late, the air became dirtied essentially with different emanations from modern cycle and fuel terminated vehicles.

Likewise with every single regular cycle, air has been given intends to purify itself. The water cycle is a decent chemical of barometrically air by method of dissipation and precipitation. These two cycles together clean the air altogether. We witness the final product of such purging as corrosive downpour where there is enormous convergence of Sulfur oxides.. Air contamination becomes unmanageable when poison load is sufficiently enormous to get weakened or cleaned by normal cycles.

Air contamination is brought about by characteristic aggravations, for example, spring of gushing lava ejection, quakes, woodland fire just as human exercises, for example, modern cycles and vehicular emanations. Shockingly, no creation other than individual, add altogether to air contamination load. Then again, they help in relieving contamination in their own particular manner. Creatures consume every one of their slaughters leaving bones which helps in treating the land with Calcium and Phosphate. Winged creatures have likewise comparative timetables. The greenery devours Carbon dioxide and breathe out Oxygen consequently improving the air quality. They additionally ingest and adsorb particulate toxins. Sunlight based radiation crumbles numerous contamination. Infrared and bright boundaries of sun oriented radiation have extraordinary intensity of obliterating toxins however these have some opposite commitments as well. The moon additionally assumes its little job. The tsunamis catalyzed during full moon period, retain poisons coasting over the ocean.

Odd-Even at Delhi

odd-even formula


   ODD-EVEN rules implemented in New Delhi twice in 2016 by AAP Government in the national capital — in January 2016 and April 2016 . Odd-even formula prevent us from air pollution. The scheme’s efficacy has been a matter of debate among experts while it had also generated a lot of political heat. Delhi Transport Minister  had earlier requested the Center to give the state government sufficient time before implementing the road-rationing measure so that people can be sensitized.

 The first phase of the odd-even scheme in January 2016. this plan for reducing the capital’s throat-searing pollution levels was simple – allow private cars to use to the streets only every other day. Except that it is no longer working. After declaring the odd-even plan a roaring success when it was introduced for a 15-day trial in January 2016, and after that second phase in apr 2016  and the preliminary results are disappointing, to say the least. Nobody was expecting the Delhi air to get a whole lot cleaner merely with the introduction of restrictions on private cars, which make up for about only 15% of the total trips in the capital. But it turns out that pollution levels actually increased in the second half of April. According to data generated by India Spend  air-quality monitoring sensors, pollution rose 23% during this period.
