The deadly consequences of the great fog of 1952 in London located in history as a health catastrophe caused by air pollution.
In the winter of 1952 cold temperatures dropped more than expected for Londoners. The December 4 could be seen a dense fog; as we know, in London, it is very common phenomenon named fog . However, the fog was not equal to that of other days , was so dense that day until the December 9 , schools suspended classes, concerts and shows were canceled and car traffic became impossible for reducing visibility across the city.
That fog coming in homes and buildings, which plunged London into a peculiar darkness, not only disturbed the life everyday in the city, but it was one of environmental catastrophes that have gone down in history as a reference to the consequences of air pollution from coal combustion in factories and houses, common then as heating to abate the cold.
The big fog took the lives of at least 4000 people who in later months they followed 8000 more
So, the thick smog produced by the activities of local factories and the means more than half a million homes They used carbon and the phenomenon of thermal inversion that occurred were mixed to make the fog dense combination of pollutants that hit London for five days straight and with consequences present several subsequent months.
In great fog (great great fog or smog), 1952 they killed at least 4000 people affected by pollutants. href=”http://www.jornada.unam.mx/2010/11/16/opinion/a03a1cie” is estimated to be released into the atmosphere tons of dioxide carbon 140 tons of hydrochloric acid and 14 tons of fluorine compounds, in addition to 370 tons of sulfur dioxide which, when combined with oxygen and water, became sulfuric acid.
dangerous mix claimed the lives of hundreds of people and it is estimated that at least 8000 people died in the months after the fog. During the health catastrophe increase was recorded up to 80% mortality rate on the previous year. In the months of January and February 1953 increases were still recorded in the rate to more than half the previous period.
After the disaster, the government took warning of the situation and already for 1956 British Parliament passed the Clean Air Act (Clean Air Act) where the use of coal for industrial processes and a series of measures that sought the use of cleaner energies are outlawed. This law was updated in 1993
