Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

The ECOSAR QSAR model predicts that 14 -day LC50 value would to be 315.602 mg/L (ppm) for freshwater sediment.

Key value for chemical safety assessment

EC50 or LC50 for freshwater sediment:
315.602 mg/kg sediment dw
EC50 or LC50 for marine water sediment:
31.56 mg/kg sediment dw
EC10, LC10 or NOEC for freshwater sediment:
63.1 mg/kg sediment dw
EC10, LC10 or NOEC for marine water sediment:
6.31 mg/kg sediment dw

Additional information

The available data for marine water sediment are limited and to obtaine the value for PNECs for saltwaters is taken account a assesment factor 10 to extrapolate to LC50 following the “Guidance on Information Requirement and Chemical Safety Assessment R.10: Characterisation of dose [concentration]- response for environment”and “Table R.10-5 Assessment factors proposed for deriving PNEC water for saltwater for different data sets”, to account for the possibility that greater taxonomic diversity in the marine environment makes it likely that some marine taxa may be more sensitive than the most sensitive freshwater taxa.
