Bibliography
Gives a method, by analysis of inorganic carbon, for evaluation in an aqueous medium the ultimate aerobic biodegradability of organic substances at a given concentration of microorganisms. Applies to organic compounds which are: a) water-soluble under the test conditions; b) poorly water-soluble under the test conditions in which case special measures may be necessary to achieve a good dispersion of the compound (see ISO 10634); c) volatile; d) not inhibitory to the test microorganisms at the concentration chosen for the test.
