Air Pollutants types and Sources, health, environmental problems of Pollutant ~ Civil Services Self Study ( NCERT Based)

There are two types of Air Pollutants:

It s not emitted directly but is formed by the reaction of primary pollutants, some examples are :

Smog (a mixture of smoke and fog),
Ground-level ozone ( formed by the reaction of Hydrocarbon (HC) and Nitrogen oxides in the presence of sunlight),
acid rain,
Persistent organic pollutants

Primary air pollutants are directly emitted from the source such as Co2, Co, etc.
The following are Primary Pollutants:

Sr No	Pollutant	Sources	Health & Environmental Problems
1	Co2	Burning of Fossil fuels like Coal, Pet Coke & Petroleum Products Transport & Manufacturing Sector Burning of Biomass burning such as crop residue & forest product	Major Green House Gases
2	CO	Incomplete incubation of Fossil fuels	Reduced the Oxygen level in Hemoglobin
3	Oxides of Sulphur (Sox)	Burning of fossil fuels like coal, Pet Coke & petroleum products	Can damage human & animal lungs, forms secondary pollutant acid rain, Cause metal corrosion and discoloring of building
4	Oxides of Nitrogen (Nox)	Burning of fossil & biomass fuels	Forms secondary pollutant acid rain, Can damage tissue, viral infections, irritation of eyes
5	Particulate Matter	The building, roads construction Mining, forest fire	Respiratory problems, Blocking of air & sunlight to vegetation, Decrease of Crop productivity
6	Hydrocarbon (HC)	Municipal Landfill, Sewage, Burning fuels	Form secondary pollutant that is ground level Ozone, Cancerous for the Human body.
