1. Potential Environmental Impact of Vapours

2. Earth`s Atmosphere Composition and Structure
Earth’s atmosphere is made up of a combination of gases. The major components of nitrogen, oxygen, and argon remain constant over time and space, while trace components like CO2 and water vapor vary considerably over both space and time.

3. Composition of Earth`s Atmosphere
Table 1: Constant Components. Proportions remain the same over time and location.
Nitrogen (N2)
78.08%
Oxygen (O2)
20.95%
Argon (Ar)
0.93%
Neon, Helium, Krypton
0.0001%

5. Structure of the Earth`s Atmosphere
Principal layers of the atmosphere
Earth's atmosphere can be divided into five main layers. These layers are mainly determined by whether temperature increases or decreases with altitude. From lowest to highest, these layers are:
Troposphere
Stratosphere
Mesosphere
Thermosphere
Exosphere

7. Gaseous pollutants Pollutant Problem Produced Sulphur oxides
Poisonous gas
Nitrous oxides
Greenhouse effect; Acid rain
Carbon Dioxide
Heat trapping gas
Carbon monoxide
A very poisonous gas
Methane
A green house gas
Chlorofluorocarbons
Destroys ozone
Ozone
Hazardous to health; corrosive to materials

8. Sources of pollutant gases
Sulfur oxide (SOx) refers to one or more of the following:
Lower sulfur oxides 
Sulfur monoxide 
Sulfur dioxide 
Sulfur trioxide  
Coal and Oil combustion, smelters

9. Sources of pollutant gases
Nitrogen oxide can refer to a binary compound of oxygen and nitrogen, or a mixture of such compounds:
Nitric oxide, also known as nitrogen monoxide,
Nitrogen dioxide 
Fuel and gas combustion

10. Sources of pollutant gases

11. Sources of pollutant gases
Carbon monoxide - Incomplete petrol and gas combustion

12. Sources of pollutant gases

20. Acid Rain

21. Acid Rain
It shows that factories produce bad things called SO2and NOx and release them into the air (These are the yellow dots on the picture). When SO2 and Nox combine with the air, acid rain is created.

22. Acid Rain

23. What's the impact of acid rain?
Deteriorates building that is made of rock
Acidification of soil and lakes
Separation of poisonous minerals such as aluminum and mercury from the surrounding ground, increasing the risk of contamination to lakes/water sources
Deteriorates trees and forests

24. Ozone Effect

25. What is being done to reduce harmful gases?
Sulphur Dioxide removal
Reducing nitrogen formation in combustion reactions
Electrostatic Precipitator
