Acid Rain: Dangerous gasses like NO are released into the atmosphere during the incineration of fuels.When it rains, the droplets combine with these pollutants, become acidic and then fall on the ground in the form of acid rain.
Ground level ozone is an important example of a secondary pollutant.
Some contaminants may be both primary and secondary: they are both emitted directly and formed from other primary pollutants.
Acid rain is a source of great harm to human beings, wildlife and crops.
Eutrophication: It is a process where a high amount of nitrogen present in some contaminants gets morphs on sea’s surface and develops itself into algae and harmfully affect fish, plant life and animal species.
The green colored algae that are present in lakes and ponds is due to the presence of this substance only.
Diminution of Ozone layer: Ozone is present in earth’s atmosphere (Stratosphere) and is responsible for shielding humans from injurious ultraviolet (UV) rays.Secondary pollutants are the contaminants which are not emitted directly into the atmosphere.They are formed in the atmosphere when prime pollutants react or intermingle.The constituents can be dense particles, fluid, or gasses. Contaminants are categorized as primary or secondary.Primary contaminants are typically created by the emission of carbon dioxide from vehicles and factories.Methane is extremely combustible and may form an explosive and volatile concoctions with air.Methane is furthermore an asphyxiant and may displace oxygen in a sealed off space.Earth’s ozone layer is diminishing because of the presence of chlorofluorocarbons and hydro chlorofluorocarbons in the atmosphere.This was a brief introduction of air pollution and its causes.Respirational and cardio complications: The adverse impacts of Air pollution are distressing.They are the root of numerous respirational and cardiac conditions accompanied by Cancer, midst other threats to our body.
