1. Man-Made (Artificial) Sources
The Majority Of Them Are Connected To The Burning Of A Variety Of Fuels.
Toxic fumes from power stations, industrial facilities (manufacturing works), industrial waste furnaces and other fuel-burning heating devices are examples of immobile sources. Traditional biomass, which includes wood, agricultural residues, and animal dung, is the primary source of air pollution in low- and middle-income nations.
A movable source is a Vehicle, a Boat, Or an Aeroplane.
Forest management, agriculture, and prairie re-establishment all make use of controlled fire on occasion. In both forest & grassland ecosystems, fire is considered as a natural part of the process. With precise burning, attractive trees are sparked to life and the forest is rejuvenated.
Other Solvent-Based Products Such As Paint And Varnish Emit Noxious Odour.
Methane is produced as a byproduct of landfilling waste. When methane and air come together, they may create a highly flammable and explosive mixture. Furthermore, methane is an asphyxiant and it may deprive a space of oxygen if it is contained. By displacement, an oxygen concentration of less than 19.5% may cause suffocation in humans.
Nuclear weapons, poison gases, germ warfare, and rocketry are some examples of military resources.
2. Natural Sources
Dirt that comes from natural sources, such as large stretches of land that lack vegetation.
In the breaking down food (digestion) by animals, such as cattle, the release of methane
Smoke and carbon dioxide emissions from forest fires.
volcanic activity, which releases sulphur, chlorine and ash particles into the atmosphere.
Air Pollution’s Major Repercussions
Air pollution harms both people and the natural environment. It might be a mixture of solids, liquids, or gases. Contaminants may come from either the natural or man-made worlds. Primary and secondary contaminants are the two main types of contaminants.
Carbon dioxide emissions from motor vehicles and industrial facilities are the most common sources of primary pollutants. A secondary pollutant is a substance that enters the environment but is not released into the atmosphere directly. Pollutants react or mix together in the atmosphere to generate these ozone depleting substances. Secondary pollutants include ground-level ozone.
While primary and secondary contaminants might exist at the same time, it is common for both to exist.
Pollution In The Air
Complications of the respiratory and cardiovascular systems: Air pollution has a debilitating effect. Many respiratory and cardiac diseases, including cancer, may be traced back to them. Millions have died as a result of air pollution, either directly or via unanticipated consequences. Pneumonia and asthma are common ailments among children who live in places with poor air quality.
Global warming: Another direct effect of global warming is the rapid changes that the globe is experiencing. There is already an approaching tragedy if action isn’t made to preserve and regulate the environment as temperatures rise throughout the planet, sea levels rise, and ice from frigid locations and icebergs melts away.
Acid Rain: The burning of fossil fuels releases toxic gases like NO2 and SO2 into the atmosphere. When it rains, these contaminants react with the water droplets, resulting in acid rain, which falls to the earth. Acid rain is a cause of considerable damage to human people, animals and agriculture.
The process of eutrophication occurs when a large quantity of nitrogen, found in certain pollutants, transforms into algae on the sea’s surface, posing a threat to marine life, plants, and animals. This chemical is the sole cause of the green algae seen in lakes and ponds.
The Earth’s stratosphere (atmosphere) has an ozone layer that protects people from harmful ultraviolet (UV) radiation. As that layer depletes, so does the protection that humans get. Ozone layer depletion is caused by chlorofluorocarbon and hydrochlorofluorocarbons being released into the air.
Prevention Of Air Pollution
The following is a list of practical steps that anybody may do to help reduce pollution in the air.
- Using public transportation and sharing a ride
- Lights should be turned off when not in use.
- Products that may be reused or recycled
- limiting rubbish incineration and smoking
- Firecrackers should not be used.
