| Resumen: | The document specifies a method, by determination of the oxygen demand in a closed respirometer, for the evaluation in an aqueous medium of the "ultimate" biodegradability of organic compounds at a given concentration by aerobic micro-organisms. The conditions described in this document do not always correspond to the optimal conditions for allowing the maximum degree of biodegradation to occur. |
