Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
A full set of freshwater studies exist for three trophic levels of water column species for short-term and long-term, chronic, end-point values, thus permitting calculation of the freshwater PNEC value with an Assessment Factor of 10.
The details are, as follows :
FISH TOXICITY :
Acute - 96 hr LC50 (OECD 203) = 1.02 mg/L
Chronic - 30-Day NOEC (OECD 210) = 0.055 mg/L
INVERTEBRATE - Daphnia magna :
Acute - 48 hr EC50 (OECD 202) = 0.38 mg/L
Chronic - 21-day NOEC (OECD 211) = 0.031 mg/L; 21-day EC10 (OECD 211) = 0.037 mg/L
ALGAE :
Acute - 72 hr ErC50 (OECD 201) = 0.74 mg/L
Chronic - 72 hr ErC10 (OECD 201) = 0.18 mg/L
The lowest chronic / reproduction NOEC is for Daphnia (i.e. 0.031 mg/L). PNEC freshwater is 3.1 ppb, based on an Assessment Factor of 10.
