Слайд 1Anthropogenic factors of occurrence instability in the biosphere
Prepared by Zhumakulova

Слайд 2What are the anthropogenic factors?
The term "anthropogenic" means of, relating
to, or involving the impact of humans on nature.
Anthropogenic sources
of pollutionStationary point sources
Mobile sources
Area sources
Evaporative sources
Controlled burns
Waste disposal landfills
Слайд 3Impact of anthropogenic factors on biosphere
Emission of chemically and physically
active substances and inert materials into biosphere
Nitrogen oxides (NOx) -
NO2 is one of the most prominent air pollutants. Nitrogen (N) compounds, emitted as NOX and NH3.Particulate matter - Particulates, alternatively referred to as particulate matter (PM) or fine particles, are tiny particles of solid or liquid suspended in a gas.
Ozone (O3) - Ozone is not directly emitted into the atmosphere
Carbon dioxide (CO2) - emitted from sources such as combustion, cement production, and respiration.
Ammonia (NH3) - emitted from agricultural processes.
Слайд 4Sulphur oxides (SOx) – Mainly Sulphur dioxide (SO2). It is
one of the causes for concern over the environmental impact
of the use of fuels as power sources.
Слайд 5Physical or mechanical impact
It is leading to change in land surface
and vegetation covererosion urbanization
ploughing
fires
Слайд 6Biological impact
Biodiversity
Biodiversity refers to the differences in living things in
an ecosystem. Increased biodiversity increases the stability of the ecosystem
as it provides for more genetic variation among species.Human destruction of habitats through direct harvesting, pollution, atmospheric changes, and other factors is especially threatening current global biodiversity.
