Pollution is the introduction of pollutants
(chemicals, genetic substances or energy in the form of noise, heat, or light)
in an environment to the extent that its effects become harmful to human
health, to that of others living organisms, the environment or the current
climate.
There is a very large number of pollution: human
pollution, diffuse pollution, chronic pollution, genetic pollution, air
pollution, electromagnetic pollution, radioactive pollution, thermal pollution,
pollution of mass tourism, space pollution, pollution of military origin,
sensitive pollution, noise pollution, light pollution, visual pollution, odor

sources (exhaust pipes, pesticide application ..)
Chronic pollution is a pollution with repeated
emissions of pollutant, or sometimes when the pollutant is very persistent.
Soil pollution can be of industrial origin,
following the presence of a polluting industry not taking all the necessary
precautions to avoid leaks, with the massive use of fertilizers or insecticides
that infiltrate the soil. soils.
These agricultural pollutions can have several
impacts on health, by touching water tables on the one hand and by
contaminating by bioaccumulation the crops growing on these soils on the other
hand.
Water pollution can have various origins among

The chronic effects of pollution on health are
two to three times higher than those estimated.

Nearly 30,000 anticipated deaths are attributed
to air pollution.
7 to 20% of cancers would be attributable to
environmental elements including chemicals, said the Minister of Ecology and
Sustainable Development, Serge Lepeltier, opening the second meetings Health
and Environment Parliament on the impacts of chemical pollution on the health
