Specific Ultraviolet Absorption (SUVA) at 254 nanometers (nm), an indicator of the humic (Natural organic matter- NOM) content of water. It is a calculated parameter obtained by dividing a sample's ultraviolet absorption at a wavelength of 254 nm (UV 254) (in m =1) by its concentration of dissolved organic carbon (DOC) (in mg/L).
