A test method for determining biodegradabilityof organic substances

In this paper, a rational test method for determining biodegradability of organic substanceunder aerobic conditions was established. Index of biodegradation was elaborated through analysis forbiodegradability of organic substances. 23 organic substance were studied with this test and their index-es of biodegradation were calculated. A classification of biodegradability of the organic substance accord-ing to the indexes of biodegradation was suggested.
