Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

For the freshwater the PNECfreshwater is derived from three chronic toxicity data: three experimental  values (fish, daphnid,algea).  For deriving PNEC, the NOEC of Fish is preferred over NOEC and growth rate is preferred over biomass (REACH guidances R10 and R7b). The PNEC is based on the data presented in table 1.

When three chronic values are available, an assessment factor of 10 may be used.. The PNECfreshwater is 0.041 mg/l.

Conclusion on classification

The experimental  NOEC for Daphnia Magna is  below  the chronic classification threshold of 1 mg/l. As a consequence  a classification  for the  aquatic  environmernt is needed. Diphenyl sulphone is classified for the  aquatic environmernt as Category : Chronic 2.
