Air Pollutants types and Sources, health, environmental problems of Pollutant

There are two types of Air Pollutants:

Secondary 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 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.
