Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 28-day NOEC for Lumbriculus variegatus was 81 mg/kg sediment dw (for LAS-Na).
Key value for chemical safety assessment
- EC10, LC10 or NOEC for freshwater sediment:
- 81 mg/kg sediment dw
Additional information
No studies on the toxicity of LAS-Ammonium to sediment organisms were available.
For LAS-Na three studies on toxicity to sediment organisms were available. No studies on sediment toxicity of IPA were available. PNECs-sediment for IPA would have to be derived on the basis of equilibrium partitioning, and were as such considered to be less acurate than a PNECs-sediment derived from toxicity data as was done for LAS-Na. The PNECs-sediment derived for LAS-Na were used as estimate
