Survival of the Brine Shrimp, Artemia Salina, After Exposure to 290-NM Ultraviolet Radiation, with and without Maximum Photoreactivation
It is possible that increased exposure of planktonic organisms to far-ultraviolet light with biologically efficient wavelengths might occur as a result of attenuation of our stratospheric ozone shield due to man’s activities. It is thus important to assess experimentally the effects this light might have upon our marine ecosystems. Ultraviolet light (UV) at 290 nm is one potentially important wavelength whose fluence at the surface of the earth might increase with a reduction in ozone(Baker, et al. 1980). For this reason, we report here studies of the lethal effects of 290 nm UV upon larvae of the salt water shrimp, Artemia saliva. These experiments allowed for full expression of dark and photorepair, enabling assessment concerning the possible impact of attenuated atmospheric ozone shielding upon this marine organism.
