— The action spectrum for superoxide production from aerated aqueous solutions of pheomela‐nin was determined by utilizing the nitroblue tetrazolium‐superoxide dismutase assay for superoxide. Superoxide production was greatest in the UVC regions, but continued well into the visible wavelengths. The marked increase in superoxide production noted in the UVC‐UVB regions of the spectrum suggests that superoxide production may be involved in a number of actinic disorders in fair‐skinned humans.
