The economic crisis apart from all others, and
has environmental consequences. As more light
over the fireplace, not now ... for
companionship, but in order to keep warm, so
to burn continuously, a cloud cover, mainly from
the afternoon hours, the neighborhoods of
Athens.

Something similar happened in London in
1952, resulting in the death of 4,000 people.
In December 1952 the smoke from fireplaces
covered for five whole days in London and lose
their lives over 4,000 people.

In those five days, where visibility was impossible
even for the pedestrians who were holding lanterns,
thousands of people died and countless others
suffering from respiratory problems.
According to 'The News', the capital of Great Britain
had drowned and sometimes the smog, but what
unfolded on December 5 of that year did not last.

Due to the cold and snowy, the Londoners were
burning large quantities of wood in fireplaces and
huge amounts of smoke in the sky evolved.
Under normal circumstances, this would create a
huge problem, as the smoke would be thrown into
the atmosphere. However, that same year, formed
one anticyclone leading one deadly trap.
(11)
What happened The anticyclone pushing air
downward-heated. Since the air when the
ground is warmer than the highest created
called inversion, leading to trap the hot smoke
coming out of the chimneys.
(13)
Apart from the smoke in their homes, the inversion
phenomenon resulted trapped particulates and other
pollutants from industries, so close to London and
from farther away, the winds had relocated to the
region.
(15)
In combination with other meteorological parameters
such as sunshine and moist winds, created a layer of
smog 100-200 meters, and released tons of
particulates, carbon dioxide, hydrochloric acid and
fluorinated compounds, and an estimated 370 tons of
sulfur dioxide were converted into 800 tons of sulfuric
acid.
(17)
Indeed, the fact that due to the phenomenon
killed 4,000 people, led the British government to
banning fireplaces in the city. Adopted a series of
laws with the principal Act for Clean Air. The
legislation banned in urban areas and wood
burning fireplaces in their homes.

As far as London is affected in 1952 by the most
destructive air pollution in history.
A thermal inversion caused by an anticyclone resulted
to trap cold air underneath a warm air mass, and
combined with the increased consumption of coal has
created a poisonous "smog" in extreme apnea lasted
from 5 to 9 December

. Visibility was so limited that stopped all transport
except the subway and even canceled screenings
because of fog had penetrated through the halls.
Most of the 12,000 victims who died in the deadly
pollution were mainly children and the elderly.
