Effects on Aquatic Biota

Ultraviolet radiation (UVR) accounts for about 7% of the radiation emitted by the sun.

The Solar radiation spectrum contains ultraviolet radiation which is broken down into ultraviolet C (UVC, 100-280 nm) 60%, ultraviolet B (UVB, 280-315 nm) 12%, and ultraviolet A (UVA, 315-400 nm) 28% ultraviolet radiation.
