Additional information

Two guideline studies on the ready biodegradability of octocrilene are available. The biodegradation of the substance was tested in two Manometric Respirometry tests according to EU Method C.4 -D and OECD guideline 301F, respectively. Both tests used non-adapted activated sludge as inoculum. At termination of the test after 28 days of inoculation the detected degradation rate was in the range of 0 - 10 % (Bayer AG 1995, BASF AG 1991). Thus, octocrilene is not readily biodegradable according to OECD criteria. The substance is considered as poorly biodegradable.
