Air pollution or air pollution
Urban air pollution is generated by transport, industry and
energy production. It is characterized by the presence of fine particles
(aerosols, especially carbon) and urban smog (including tropospheric ozone).
On average, atmospheric pollution causes the premature death
of 7 million people worldwide, including 600,000 in Europe and 48,000 in
France, according to the World Health Organization and the Ministry of
Sustainable Development.
Finally, while a population of more than 1.7 billion people
still depends on manure, wood, crop residues and coal to meet their basic
energy needs, indoor air pollution Of households would be responsible for more
than 1.6 million deaths per year according to estimates. This pollution
particularly affects women and children who spend more time in the home.
A scourge too often passed over in silence.
Air pollution: definition
Atmospheric pollution therefore means the undesirable
presence of impurities or the "abnormal" rise in the proportion of
certain constituents of the atmosphere. The Law on Air and the Rational Use of
Energy (known as the Lepage Law and the LAURE Law) of 30 December 1996 proposes
a definition: "Air pollution within the meaning of this Law means the
introduction by man, Directly or indirectly, in the atmosphere and confined
spaces, of substances having adverse consequences that may endanger human
health, harm biological resources and ecosystems, influence climate change,
damage property , To cause excessive nuisance olfactory. "
The atmospheric part of the atmosphere encompasses the
troposphere (up to 8 to 15 km altitude depending on latitude) and the
stratosphere (15 to 50 km altitude). Indeed, emissions of pollutants with a
lifetime of more than 5 years can reach the stratosphere. The concentration and
/ or dispersion of pollutants then generally depend on weather conditions.
The different atmospheric pollutants
Atmospheric pollutants act at different scales: some gaseous
compounds have no local effect but may disturb the global climate equilibrium,
while others are particularly virulent for local and regional health but have a
very limited influence on The atmosphere as a whole.
