Algae
ErC50 (72 h) > 100 mg/L (nominal, OECD 201, P. subcapitata); read-across
Aquatic long-term toxicity
Fish
No data available
Aquatic invertebrates
No data available
Algae
NOEC (72 h) ≥ 100 mg/L (nominal, OECD 201, P. subcapitata); read-across
Conclusion on CLP
Based on the available data compiled above, aquatic invertebrates are the most sensitive trophic level for short-term aquatic pelagic toxicity with an EC50 (48 h) of 48 mg/L. One effect value is available for the long-term toxicity to aquatic algae, indicating no effects up to the nominal concentration of 100 mg/L. Moreover, the substance is not readily biodegradable. Therefore,the substance is classified and labelled as Aquatic Chronic 3 (H412) for long-term hazards to the aquatic environment,according to the consolidated version of Regulation (EC) No 1272/2008 (dating 01.03.2018) and further amendments (ATPs).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
