A physical, biological or chemical alteration to the air in the atmosphere can be termed as pollution. It occurs when any harmful gases, dust, smoke enters into the atmosphere and makes it difficult for plants, animals and humans to survive as the air becomes dirty.

Stratospheric Pollution and its Causes

Stratospheric pollution is the presence of pollutants in the stratosphere, which is the second layer of the Earth's atmosphere. Stratospheric pollution has a significant impact on the environment and human health. The causes of stratospheric pollution are:

Breakdown of Ozone

Ozone is a gas that absorbs ultraviolet (UV) radiation from the sun, protecting life on Earth from harmful radiation. However, chemicals like chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) that are used in refrigerants, air conditioners, and aerosol sprays can break down ozone molecules. This leads to the formation of a hole in the ozone layer, which can lead to increased skin cancer, cataracts, and other health problems.

Oxides of Nitrogen

Oxides of nitrogen are pollutants that are released into the atmosphere from fossil fuel combustion in vehicles and power plants. These pollutants can react with other chemicals in the atmosphere to form nitric acid, which can cause acid rain. Acid rain can damage forests, crops, and buildings.

Photochemical Smog

Photochemical smog is a kind of air pollution that is caused by the interaction of sunlight with pollutants in the atmosphere. It is formed when nitrogen oxides and volatile organic compounds (VOCs) from sources like car exhaust and industrial emissions react in the presence of sunlight. Photochemical smog can cause respiratory problems, eye irritation, and other health problems.

Particulate Matter

Particulate matter is a type of air pollution that consists of tiny particles of dust, dirt, and other materials. These particles can come from sources like construction sites, vehicle exhaust, and wildfires. When inhaled, particulate matter can cause respiratory problems, heart disease, and other health problems.

Conclusion

Stratospheric pollution is a serious problem that can have significant impacts on the environment and human health. The causes of stratospheric pollution are primarily related to human activities, such as the use of certain chemicals and fossil fuel combustion. It is important to take steps to reduce stratospheric pollution to protect the health of the planet and its inhabitants.

Ozone is present in stratosphere .so breakdown of ozone is stratospheric pollution.
