Description of key information

The substance is not readily biodegradable according to OECD criteria, but can be easily eliminated from water.

Key value for chemical safety assessment

Additional information

In a GLP guideline study according to OECD 301B a biodegradation of <10 % was observed (BASF 2014). This result is supported by a GLP guideline study according to OECD 301F where a biodegradation of 1.2 % was observed (RCC 1999). Hence, the substance is poorly biodegradable. The poor biodegradability of the test substance is also confirmed by a japanese GLP guideline study in which no biodegradation was observable (Gakushuin 2000).

Additional information is given from a Zahn Wellens test (OECD 302B). After 3 hours 73 % of DOC removal was measured indicating adsorption potential of the substance. It is thus easily eliminable from water (Solvias 2000).
