Toxic effect of uranium on freshwater algae <i>Chlorella vulgaris</i>
The toxicity of aqueous solutions of uranyl nitrate for freshwater algae Chlorella vulgaris was investigated. No observed effect concentrations and the effective concentrations were determined. Relative contribution of DNA reparation and glutathione-dependent pathway of detoxification in response of Сhlorella algae to uranium was evaluated. It is shown that different molecular mechanisms are involved in the response of Chlorella vulgaris to uranium, and change their contribution to the regulation of the metabolic systems of the cells resulted to divergent biological responses at different concentrations of the element.
