Nettet26. aug. 2024 · The ozone layer in the upper atmosphere, or stratosphere, blocks UV radiation that can damage living tissue, including plants. The ozone “hole,” discovered in 1985, is the result of humans emitting chlorofluorocarbons (CFCs), which are ozone-depleting chemicals and greenhouse gases that were once commonly used as coolants … Nettet22. jan. 2010 · Study now. See answer (1) Best Answer. Copy. Electromagnetic waves called UV radiation. Ozone layer blocks out most UV radiation by absorbing it and that is important, because UV radiation can ...
Ozone Generation by Ultraviolet Lamps - Wiley Online Library
NettetStratospheric ozone depletion due to human activities has resulted in an increase of ultraviolet radiation on the Earth's surface. The article describes some effects on human health, aquatic ecosystems, … Nettet28. mai 2024 · Ultraviolet radiation is broken into three sub-categories: UV-A, UV-B, and UV-C. UV-C radiation (wavelengths less than 280 nm) is very dangerous to animals and plants but is completely absorbed by ozone in the stratosphere and doesn’t reach the surface. Ozone also absorbs much of the UV-B radiation but some radiation still … mls commissioners office
Ultraviolet Radiation: How It Affects Life on Earth - NASA
Nettetabout the UV-C generation of ozone. It is well known that wavelengths below 240 nm more readily generate ozone. However, there is a great misunderstanding with regard to the actual generation and dissipation of ozone molecules by UV-C lamps. A review of this subject is much warranted. An overview of the ozone generation of various UV-C light Nettet29. jun. 2005 · [1] The interest in solar ultraviolet (UV) radiation from the scientific community and the general population has risen significantly in recent years because of the link between increased UV levels at the Earth's surface and depletion of ozone in the stratosphere. As a consequence of recent research, UV radiation climatologies have … Nettet18. jun. 2024 · The over all reaction between oxygen and ozone formation is: (4) 3 O 2 ⇌ 2 O 3. The absorption of UV B and C leads to the destruction of ozone. (5) O 3 + h ν → O + O 2. (6) O 3 + O → 2 O 2. A dynamic equilibrium is established in these reactions. The ozone concentration varies due to the amount of radiation received from the sun. mls condos pittsford ny
