CFCs (carbon, chlorine, and fluorine atoms) are found in aerosol sprays, refrigerants, and other products. Although these chemical compounds are not reactive in the lower atmosphere, CFCs react with UV rays in sunlight to release inorganic chlorine. The root problem of leaks in the ozone layer (a screen that protects us from damaging UV rays) in the polar areas is chlorine.
The gloom or fog that leads to the identification of air pollution is known as smog (due to burning fossil fuels. Read the whole article below to grasp a good knowledge about it.
What Is The Meaning of Air Pollution?
Air is made up of 78 percent nitrogen, 21 percent oxygen, and 0.9 percent argon. Carbon dioxide, water vapor, hydrogen, and other trace elements are among the remaining elements. Despite the fact that gases like carbon dioxide and methane exist in minuscule absolute amounts, their enormous heat-trapping capability as greenhouse gases makes them a substantial contributor to climate change acceleration. Air pollution happens when the chemical, physical, or biological qualities of the air are altered, either by volume or by chemical, physical, or biological properties. The balance of elements and particles in the atmosphere is fragile. Any imbalance, even in minor amounts, can be harmful to living beings such as animals and crops.

Air pollution is created by a mixture of gaseous and particulate pollutants including carbon dioxide, methane, and nitrogen dioxide emitted by point sources like industries and motor vehicles that consume fuel. Some gaseous emissions can be seen with the naked eye, whereas others may dissolve into the atmosphere and become unseen. Particulate pollution, such as soot and black carbon, on the other hand, is always visible.
Which Type of Pollution Includes CFCs And Smog?
Biological molecules, nutrients, and gases such as smog, chlorofluorocarbons, CFCs, hydrochlorofluorocarbons, HCFCs, aerosols, and others are all produced by air pollution. CFCs and CFCs are two of the major sources of pollution in the air. Haze is a form of air pollution that is more difficult to detect. The word “smog” and the phrase “smog” were originally used to describe a mixture of smoke and mist in the early 1900s. Smoke from burning coal is ubiquitous, and pollution is popular in industrial regions.

Chlorofluorocarbons, or CFCs (commonly known as Freon), are non-toxic, non-flammable, and non-carcinogenic. Carbon, fluorine, and chlorine atoms make up their structure. The Earth’s protective ozone layer, which shields the globe from damaging ultraviolet (UV-B) rays created by the sun, is destroyed by chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and halons. CFCs and HCFCs can also heat up the Earth’s bottom layer, affecting the global climate. Hydrofluorocarbons (HFCs) can also help the environment repair.
Human-made chemicals, such as chlorofluorocarbons (CFCs), hydrofluorocarbons (HCFCs), and halons, deplete the ozone layer in the upper atmosphere (stratosphere). The stratospheric layer of ozone contributes to keeping life alive on Earth by insulating it from harmful UV (UV-B) rays emitted by sunlight. Because the stratospheric layer has lower oxygen levels, more UV-B light can reach the Earth’s surface.
Too much air pollution is hazardous to one’s health and can even be deadly in small doses. Around 200 of them are controlled by legislation, with mercury, lead, dioxins, and benzene being the most widespread.
The EPA has classed benzene as a carcinogen, which can cause short-term irritation of the eyes, skin, and lungs, as well as long-term blood issues. Dioxins, which are widely present in food but also in minute levels in the air, can impair the immune system, neurons, and endocrine systems, as well as reproductive functions, in a short period of time.
The central nervous system is attacked by mercury. Lead can harm children’s brains and kidneys in big doses, and even a small amount of contact can alter their IQ and learning abilities.
What Are The Guidelines For Reducing Air Pollution?
There are several strategies for preventing, controlling, and eventually reducing air pollution:
Production of renewable fuels and clean energy. Moving away from fossil fuels and replacing them with alternative energies such as solar, wind, and geothermal is the most essential solution for air pollution.
Energy efficiency and conservation. It is critical to generate renewable energy. But it’s also critical to limit our energy consumption by embracing responsible practices and employing more energy-efficient gadgets.
Transportation that is environmentally friendly. Air pollution could be reduced by switching to electric and hydrogen automobiles, as well as increasing shared transportation (carpooling and public transportation).
Buildings that are environmentally friendly. Green construction attempts to create ecologically responsible and resource-efficient structures from conception through destruction in order to minimize their carbon footprint.
Conclusion
Air pollution, which includes CFCs and Somg, occurs when gases escape into the atmosphere, depleting the ozone layer and lowering visibility which means somg. The transition to renewable energy (such as solar and wind power) and improving the efficiency of automotive energy sources.
We can do this by replacing our fuel-efficient cars and trucks with electric counterparts. We’ll reduce the amount of pollution released into the atmosphere. By reading this article, an individual will have a clear understanding of ‘which type of pollution includes CFCs and Smog’.
