1. Atmosphere pollution

3. Types of pollution
www.airly.eu
 Particulate matter
(PM)
Nitrogen oxides(NO, NO2)
Ozone (O3)
Sulfur oxides(SO2, SO3)
Carbon oxides (CO, CO2)
Methane (CH4)

4. Sources of pollution:
1. Industry
2. Transport
3. Low emission

5. Particulate matter www.airly.eu
The particulate matter is a mixture of very small-
diameter particles of dust suspended in the air.
Various types of chemical compounds are absorbed
on the surface of particulate matter, e.g. heavy metals
such as cadmium, lead and mercury.
Due to the small dimensions, particulate matter is a
significant threat to human health because it can
penetrate the lower levels of respiratory tract.

7. Nitrogen oxides www.airly.eu
Changes in NO2 emissions dueto industrial
production restrictions due to a pandemic.
Example: CHINA

10. Carbon monoxide (CO, CO2)
… together with methane (CH4) are the
greenhouse gases.
