Ózonkibocsátás

Ózonkibocsátás refers to the release of ozone (O3) into the atmosphere. Ozone is a molecule composed of three oxygen atoms. It exists in two main regions of the Earth's atmosphere: the stratosphere and the troposphere.

Stratospheric ozone, often called "good ozone," forms a layer that absorbs most of the Sun's harmful ultraviolet (UV) radiation, protecting life on Earth. Ozone depletion in this layer, caused by human-produced chemicals like chlorofluorocarbons (CFCs), is a significant environmental concern.

Tropospheric ozone, located closer to the Earth's surface, is considered a "bad ozone." It is a major component of smog and is formed through chemical reactions involving pollutants from sources like vehicle exhaust, industrial emissions, and power plants, in the presence of sunlight. This ground-level ozone can harm human health, causing respiratory problems, and also damage vegetation and ecosystems.

The measurement of ózonkibocsátás often focuses on ground-level ozone concentrations, particularly in urban areas and industrial regions. Understanding and controlling the sources of precursors that lead to tropospheric ozone formation is crucial for air quality management and public health. International agreements and national regulations aim to reduce emissions of these precursor pollutants, thereby mitigating the negative impacts of ózonkibocsátás at ground level.
