![]() In recent decades, emissions from diesel motor vehicles have seen London’s air quality re-emerge as a public safety hazard.Required new furnaces to be smokeless and that grit and dust should be minimised.The Act also included measures to prevent the emission of dark smoke from chimneys.By shifting domestic sources of heat towards cleaner coals, electricity, and gas.Introduction of “smoke control areas” in towns and cities in which only smokeless fuels could be burned.The Act introduced a number of measures to reduce air pollution.Most of the deaths were caused by respiratory tract infections,ü from hypoxia and as a result of mechanical obstruction of the air passages by pus arising from lung infections caused by the smog.1,00,000 more were made ill by the smog’s effects on theü human respiratory tract.The real number of fatalities is now believed to be closer to ü 10,000.UK government would estimated that 4,000 lives were due to theü smog.370 tonnes of sulphur dioxide which may have been converted to 800 tonnes of sulphuric acid.According to the UK’s Met Office, the following pollutants were emitted each day during the smoggy period:.It caused major disruption by reducing visibility and even penetrating indoor areas.The absence of significant wind prevented its dispersal and allowed an unprecedented accumulation of pollutants.The resultant fog, mixed with smoke, particulates and other pollutants such as sulphur dioxide, formed a persistent smog.On 4 December 1952, an anticyclone settled over a windless London, causing a temperature inversion with cold, stagnant air trapped under a layer (or “lid”) of warm air.There were also numerous coal-fired power stations in the Greater London area.Post-war domestic coal tended to be of a relatively lowgrade, sulphurous variety because better-quality “hard” coals tended to be exported.The cold weather preceding and during the Great Smog led Londoners to burn more coal than usual to keep themselves warm.Pollution and smoke from vehicle exhaust-particularly from steam locomotives and diesel-fuelled buses.Airborne pollutants arising from the use of coal.Henry Antoine Des Voeux in his 1905 paper, “Fog and Smoke” for a meeting of the Public Health Congress. Coinage of the term “smog” is often attributed to Dr.Fog can be considered a type of low-lying cloud and is heavily influenced by nearby bodies of water, topography, and wind conditions.The smell of the fog was different too, a smoky, chemical smell.The 1952 fog was strange – yellow-black in colour and thicker than the residents of the always foggy London had seen before.London had suffered since the 13th century from poor air quality, which worsened in the 1600s. ![]() and public awareness of the relationship between air qualityü and health.This was the worst air-pollution event in the history of the United Kingdom and the most significant in terms of its.A thick layer of smog over the city lasted for 5 days and killed thousands.The great smog was a severe air-pollution event that affected the British capital of London from 5th -9th December 1952.
