A correlation study of biodegradability determinations with various chemicals in various tests.

Abstract Forty-four compounds covering a range of physical, chemical, and biological properties were tested for their biodegradabilities in seven tests, the coupled units test, i.e., the modification of the OECD Confirmatory Test to the use of the carbon analysis, the Zahn-Wellens test, the Japanese MITI test, the French AFNOR T 90–302 test, the carbon dioxide evolution test according to Sturm, the OECD Screening Test modified for the use of the carbon analysis, and the closed bottle test. Conclusions regarding the individual tests are drawn from comparisons with the other test results.
