Vitamin D Synthesis under Changing UV Spectra,of events triggered by UV-B exposure. To be more specific, cutaneous vitamin D synthesis requires radiation at wavelengths less than 315 nm, the same wavelengths which are most detrimental in other aspects. However, vitamin D synthesis occurs at doses far below those of a minimal erythemal dose (MED作者: 投票 時(shí)間: 2025-3-23 02:17 作者: textile 時(shí)間: 2025-3-23 06:13 作者: Neuralgia 時(shí)間: 2025-3-23 10:18 作者: ELUDE 時(shí)間: 2025-3-23 16:30 作者: implore 時(shí)間: 2025-3-23 19:39

Ocular Damage by Environmental Radiant Energy and Its Prevention,. The cornea absorbs ultraviolet energy of wavelengths shorter than 300 nm and can be damaged by it (photokeratitis). Another target of UV damage is the DNA in the nuclei of corneal epithelial cells. Repair of the DNA is quite rapid, however, as is the replacement of damaged cells (Pitts ., 1986).

Ultraviolet Radiation and Its Effects on Organisms in Aquatic Environments,the impact of UVR on terrestrial plants.
