Anthropogenic factors of occurrence instability in the biosphere

1. Anthropogenic factors of occurrence instability in the biosphere

Prepared by Zhumakulova Aidana

2. What are the anthropogenic factors?

• The term "anthropogenic" means of, relating to, or involving the impact of
humans on nature.
Anthropogenic sources of pollution
Stationary point sources
Mobile sources
Area sources
Evaporative sources
Controlled burns
Waste disposal landfills

3. Impact 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.
Ozone (O3) - Ozone is not directly emitted
into the atmosphere
Particulate matter - Particulates, alternatively referred
to as particulate matter (PM) or fine particles, are tiny
particles of solid or liquid suspended in a gas.
Carbon dioxide (CO2) - emitted from sources such as
combustion, cement production, and respiration.
Ammonia (NH3) - emitted from agricultural processes.

4.

• Sulphur 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.

5. Physical or mechanical impact

It is leading to change in land surface and vegetation cover
erosion
urbanization
ploughing
fires

6. Biological 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.

7. Removal and destruction of nonrenewable and renewable resources

8. Changes in properties of basic elements of biosphere

Change in composition and properties of atmosphere
• Pollution
• Electrical conductivity
• Radiation properties
Change in composition and properties of inland and World Ocean water
• Pollution
• Mineralization

9. Changes in properties of basic elements of biosphere

Change in composition and properties of lithosphere
• Mechanical disturbances
• Waste accumulation etc.
Change in composition and properties of land surface and soil
• Integrity
• Acidity
• Radiation characteristics

10. Changes in properties of basic elements of biosphere

Change in composition and properties of
large systems:
• Climatic systems
• Biosphere as a whole
