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.

one of the causes for concern over the environmental impact

of the use of fuels as power sources.

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.
