For the past few years, cities in northern India have been covered in a thick layer of winter smog. The situation has turned quite drastic in the National Capital, Delhi. This smog is caused by the collection of Particulate Matter a very fine type of dust and toxic gases in the air due to stagnant movement of air during winters.
During the autumn and winter months, some million tons of crop residue are burntand winds blow from India's north and northwest towards east. For the past few years, cities in northern India have been covered in a thick layer of winter smog.

The situation has turned quite drastic in the National Capital, Delhi. This smog is caused by the collection of Particulate Matter a very fine type of dust and toxic gases in the air due to stagnant movement of air during winters.
InDelhi won the United States Department of Energy 's first 'Clean Cities International Partner of the Year' award for its "bold efforts to curb air pollution and support alternative fuel initiatives". London[ edit ] Victorian London was notorious for its thick smogs, or " pea-soupers ", a fact that is often recreated as here to add an air of mystery to a period costume drama Inconcerns over air pollution were sufficient for Edward I to briefly ban coal fires in London.
The " Ballad of Gresham College " the same year describes how the smoke "does our lungs and spirits choke, Our hanging spoil, and rust our iron. Initially a flu epidemic was blamed for the loss of life.
In the Clean Air Act started legally enforcing smokeless zones in the capital. There were areas where no soft coal was allowed to be burned in homes or in businesses, only cokewhich produces no smoke. Because of the smokeless zones, reduced levels of sooty particulates eliminated the intense and persistent London smog.
It was after this that the great clean-up of London began. One by one, historical buildings which, during the previous two centuries had gradually completely blackened externally, had their stone facades cleaned and restored to their original appearance. Victorian buildings whose appearance changed dramatically after cleaning included the British Museum of Natural History.
A more recent example was the Palace of Westminsterwhich was cleaned in the s. Other areas[ edit ] Other areas of the United Kingdom were affected by smog, especially heavily industrialised areas.
The cities of Glasgow and Edinburgh, in Scotland, suffered smoke-laden fogs in Des Voeux, commonly credited with creating the "smog" moniker, presented a paper in to the Manchester Conference of the Smoke Abatement League of Great Britain about the fogs and resulting deaths.
Due to its location in a highland "bowl", cold air sinks down onto the urban area of Mexico Citytrapping industrial and vehicle pollution underneath, and turning it into the most infamously smog-plagued city of Latin America.
Within one generation, the city has changed from being known for some of the cleanest air of the world into one with some of the worst pollution, with pollutants like nitrogen dioxide being double or even triple international standards. Other aggravates of the situation reside in its high latitude 31 degrees South and dry weather during most of the year.

PREPRINT - ACCEPTED PAPER IEEE TRANSACTIONS ON INTELLIGENT TRANSPORTATION SYSTEMS 1 A stigmergy-based analysis of city hotspots to discover trends and anomalies in urban.
Particularly to developing countries like China, urban transport is identified as one of the main contributors to the deteriorating urban air pollution (Li et al., , Zhang and Lahr, ). Hence, it is quite serious to seek a package of efficient solutions to better regulate the car usage for reducing the emissions (Hao et al., , Tao.
