| Summary: | Ozone depletion is resulting into increase in ultraviolet radiation level in the world. Exposure to UV radiation has been found to have negative effects on aquatic and terrestrial organisms. Adverse effect of natural solar and artificial ultraviolet-B and UV-A radiations was observed in crustacean species Daphnia magna in presence of retene and riboflavin. Daphnia magna exposed to artificial ultraviolet-B with retene causes maximum physiological changes and mortality, indicating that enhanced solar UV-B exposure could be lethal to aquatic fauna. Artificial UV-B had a stronger damaging effect than solar radiation and become highly toxic in presence of retene. Riboflavin is slightly phototoxic in presence of solar and artificial UV radiation. Results on mortality rate indicated highest mortality in retene + ultraviolet-B exposed group followed by riboflavin + artificial ultraviolet - B radiation. A dose and intensity dependent change in mortality rate was observed. Retene and riboflavin photoproducts with ultraviolet radiation generate reactive oxygen species leading to cell injury and mortality thus are threat to aquatic biodiversity.
