Web25 de jul. de 2024 · The "ozone layer," approximately 6 through 30 miles above the Earth's surface, reduces the amount of harmful UV radiation reaching the Earth's surface. Tropospheric or ground-level ozone – what we breathe – is formed primarily from photochemical reactions between two major classes of air pollutants, volatile organic … 1. Creation: an oxygen molecule is split (photolyzed) by higher frequency UV light (top end of UV-B, UV-C and above) into two oxygen atoms (see figure): 2. The ozone–oxygen cycle: the ozone molecules formed by the reaction above absorb radiation having an appropriate wavelength between UV-C and UV-B. The triatomic ozone molecule becomes diatomic molecular oxygen plus a free oxygen atom (see figure): nordwind offshore

WebEffects of UV Radiation on Humans. UV-B radiation does not penetrate far into the body because most of it is absorbed in the superficial tissue layers. Therefore, much of the UV damage affects the skin and eyes. However, there are also systemic effects. UV-B is the main cause of sunburn and tanning and the formation of vitamin D 3 in the skin. WebOzone formation takes place by placing dry oxygen in ozonizer and passing it through high voltage electric current by silent electric discharge. ... Formation of Ozone. The reaction of UV radiation with O 2 or dioxygen molecules results in the formation of O 3. The UV radiation splits the oxygen molecule into the free oxygen or O atoms.

WebWhen high-energy ultraviolet rays strike ordinary oxygen molecules (O 2 ), they split the molecule into two single oxygen atoms, known as atomic oxygen. A freed oxygen atom then combines with another oxygen molecule to form a molecule of ozone. O2 + high energy radiation = two free O atoms. WebDescribe the process by which chlorofluorocarbons destroy ozone molecules in the stratosphere. CFC molecules break apart high in the stratosphere, where UV radiation a powerful energy source, is absorbed. Once CFC molecules break apart, parts of the CFC molecules destroy protective ozone.
