Additional information

The test substance was investigated for its ready biodegradability in a manometric respirometry test over 28 days based on OECD Guideline 301F and in accordance with GLP (Magor 2000). The chemical oxygen demand (COD) of the test substance was determined to be 0.866 g O2/g test material. The biochemical oxygen demand (BOD) was determined to be <0.05 g O2/g test material during the whole experimental period. The biodegradation after 28 days was determined to be <5%. The biodegradation of the reference substance (sodium acetate) was 58% after 5 days and 64% after 10 days. On the basis of the screening test results, the test substance is considered as not readily biodegradable.
