Additional information

Experimental data are available for CAS 147 -14 -8. In a key study conducted similar to OECD guideline 301F (Manometric respirometry test) domestic activated sludge was used as inoculum. A degradation rate of less than 1 % was determined after 28 days (based on O2 consumption, BASF AG, 1988). This result was supported by a second test accomplished according to OECD guideline 301 C. This test was conducted under supervision of the Japanese Ministry of the Environment. The study was performed with a mixture of sewage, soil and natural water as inoculum. The substance was degraded by 0 % based on the O2 consumption after 14 days of incubation (NITE, J-CHECK databank, Japan 1992).

Based on the available experimental data it can be concluded that the substance (CAS 147-14-8) is not readily biodegradable according to OECD criteria.
