THE MAIN
SOURCES
Atmospheric
emissions of natural origin
Forest
fires, bush fires and volcanism can cause atmospheric emissions of pollutants.
Anthropogenic
emissions
Anthropogenic
atmospheric emissions are emissions of human origin.
The
distinction is commonly made according to the nature of the sources of
emissions (mobile or fixed sources) or the sector of activity. The majority of
human activities are the direct or indirect source of pollutant emissions.
Industrial
facilities or power generation plants
Industry is
a sector responsible for much of the air emissions.
The use of
electricity does not emit pollutants at the place of consumption, but it very
often generates emissions at the place where this electricity is produced.
Examples of pollutants emitted by this sector: sulfur dioxide (SO2), dust,
metals, volatile organic compounds (VOCs).
transport
network
Whether the
mode of transportation is air, sea or automobile, it contributes to emissions
of air pollutants. Examples of pollutants emitted by this sector: nitrogen
oxides (NOx), particulates in exhaust gases, carbon monoxide (CO).
Household
garbage incineration
Any
combustion generates emissions, the burning of waste either by an individual or
in a dedicated facility is causing pollution. Examples of pollutants emitted:
metals, hydrochloric acid (HCI), dioxins.
Agriculture
The
agricultural sector is responsible for some of the air pollution, through the
use of machinery in particular, but also because of the use of plant protection
products or spreading (ammonia emission). Examples of pollutants emitted: dust,
ammonia (NH3).
Domestic
activities
By using
plant protection products, paints, household products, cooking ... we all emit
atmospheric pollutants. Examples of pollutants emitted: volatile organic
compounds.
Individual
and collective heating
This sector
is responsible for much of the emissions in temperate regions.
The
pollutants concerned are usually sulfur dioxide, carbon monoxide, nitrogen
oxides or even fine particles.
Air
conditioning indirectly generates emissions because of its high electricity
consumption but also if the refrigerant gas is not recovered.
