Types of pollution:
Air pollution:
Air pollution is the degradation
of the air we breathe because of pollutants that enter the atmosphere. Peaks of
air pollution often occur in summer. The main air pollutants are fine
particles, sulfur dioxide (SO2), ozone, nitrogen oxides (NO and NO2), volatile
organic compounds (VOCs), etc.
Air pollution is mainly caused by
transport (light or heavy vehicles) and combustion plants (including biomass
combustion).
Dioxins are a family of 210
compounds of which 17 are toxic. At least one dioxin is carcinogenic to humans.
Dioxins are produced during combustion in fires or refuse incinerators.
According to the French Agency for
Environmental Health Safety (AFSSE), air pollution, linked for nearly a third
to the polluting emissions of cars, would be responsible each year for the
death of 6,500 to 9,500 people in France.
It seems that since the awareness
of greenhouse gases and their influence on the climate, the taking into account
of air pollution is "out of fashion", or even completely forgotten.
What about nitrogen oxides and carbon monoxide?
The water pollution:
Water pollution is contamination
by waste, chemicals or micro-organisms.
Water pollution is due:
1.
to agriculture (because of pesticides and fertilizers).
2.
household waste (drugs and biocides released via wastewater that are not
treated by treatment plants and lagooning).
Phosphates pollute the watercourse
by a phenomenon called eutrophication: the stream is asphyxiated by the
proliferation of algae for which phosphate acts as fertilizer. The water is
polluted by the oil spills but especially by the oil discharges of the boats.
In many places, wastewater is not
treated before it is discharged, as it is very expensive. As a result, a large
amount of wastewater is discharged into the sea. This can cause, for example,
algae that reproduce very quickly. They cover the surface of the sea and may
clog the gills of fish. Wastewater treatment is therefore important for
ecology. Every year thousands of fish die because of pollution.
[edit] Soil
pollution:
The concept of soil pollution
refers to all forms of pollution affecting any type of soil (agricultural,
forestry, urban
...).
Polluted soil in turn becomes a
possible source of direct or indirect diffusion of pollutants into the
environment, via water, dust particles, gaseous emissions or via a
concentration and transfer of pollutants by living organisms (bacteria, fungi ,
plants in turn eaten by animals.
For example, at the beginning of
the 2000s, France estimates that 230,000 sites are known to have been polluted
or potentially polluted by industry or services in country 1, nearly 4,000 of
which are monitoring, diagnostic or rehabilitation measures 1. To this should
be added the old municipal landfill sites (at least one for each of the 36 000
municipalities), and pollution from military, agricultural, hunting and other
sources.
In the
United States, a special fund called Super Fond, with polluters' contribution,
is dedicated to the treatment of the most serious cases, under the direct
authority of the Federal State
