| Concentrations of Se(IV) and Se(VI) in different drinking waters have been determined by the extraction-photometric redox method. Selenium factor characteristics of natural sources have been found which reflect current conditions of their functioning. The total selenium concentration does not exceed the maximum permissible value. |
