ózonképzdési

Ózonképzdési refers to the process of ozone formation. Ozone (O3) is a molecule consisting of three oxygen atoms. It is an unstable and reactive gas that occurs naturally in the Earth's atmosphere. The primary mechanism for ozone formation in the stratosphere involves ultraviolet (UV) radiation from the sun. When high-energy UV-B and UV-C radiation strikes oxygen molecules (O2), it splits them into individual oxygen atoms (O). These free oxygen atoms then collide with other oxygen molecules, forming ozone (O3). This process is a continuous cycle, with ozone also being destroyed by UV radiation and other chemical reactions.

In the troposphere, the lower layer of the atmosphere, ozone formation is largely anthropogenic. It is a key component of smog and is created through photochemical reactions involving pollutants. Sunlight reacts with nitrogen oxides (NOx) and volatile organic compounds (VOCs) emitted from sources like vehicle exhaust and industrial processes. These reactions produce ozone at ground level. Unlike stratospheric ozone, which protects us from harmful UV radiation, tropospheric ozone is a harmful air pollutant with detrimental effects on human health and vegetation. Therefore, understanding ózonképzdési is crucial for both atmospheric science and environmental protection.
