What is air pollution?

Air pollution can be defined as an alteration of air quality that can be characterized by measurements of chemical, biological or physical pollutants in the air. – It can be classified in 2 sections: visible and invisible air pollution.

Local.

this concerns the quality of ambient air within a radius of a few kilometers

Regional.

pollution like acid rain, photochemical reactions and degradation of water quality at distances of a few kilometers to a thousand kilometers

Global.

depletion of the ozone layer and global warming caused by the emission of greenhouse gases, mainly carbon dioxide (CO2)

Air pollution causes

Air pollution is caused by the presence in the atmosphere of toxic substances, mainly produced by human activities.

Anthropogenic air pollution sources are:

---

• 1.Combustion of fossil fuels, like coal and oil for electricity and road transport, producing air pollutants like nitrogen and sulfur dioxide
• 2.Emissions from industries and factories, releasing large amount of carbon monoxide, hydrocarbon, chemicals and organic compounds into the air
• 3.Agricultural activities, due to the use of pesticides, insecticides, and fertilizers that emit harmful chemicals
• 4.Waste production, mostly because of methane generation in landfills

Air pollution effects

1. ON THE ENVIRONMENT
