Description of key information
Additional information
The aerobic biodegradation of diphenyl sulphone was estimated by BIOWIN version 4.10. included in the EpiSuite programs of US-EPA. The conclusion of BIOWIN is that diphenyl sulphone is not readily biodegradable in a standard OECD 301C (MITI) test. The mineralisation is estimated to take weeks and the primary degradation occurs within a timeframe of days.
The aerobic biodegradation of diphenyl sulphone was estimated by the models Biowin 1 and Biowin 2, included in BIOWIN, which are intended to convey a general indication of biodegradability under aerobic conditions, and not for any particular medium. The models show that Diphenyl sulphone biodegrades fast.
Half lives in surface water and sediment were estimated with the PBT profiler (US-EPA) which calculates half life values from ultimate biodegradation estimations in the Biowin 3 model included in BIOWIN. The calculated half life values for Diphenyl sulphone are 15 days for surface water and 140 days for sediment.Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
