Description of key information
Additional information
Short-term toxicity to fish
With high probability acutely not harmful to fish.
96-h LC50 = 11800 mg/L (meas., Pimephales promelas)
Long-term toxicity to fish
No experimental data available. However, based on acute toxicity data and ACR-approach of ECETOC, no chronic effect are expected.
Short-term toxicity to aquatic invertebrates
With high probability acutely not harmful to aquatic invertebrates.
48-h EC50 > 222 mg/L (meas., Daphnia magna)
Long-term toxicity to aquatic invertebrates
Chronic effects are not expected.
21-d NOEC = 16 mg/L (nom., Daphnia magna; read-across: CAS 102-71-6)
Toxicity to aquatic algae
With high probability acutely not harmful to algae.
Chronic effects are not expected.
72-h ErC50 = 311 mg/L (meas., Desmodesmus subspicatus)
72-h ErC10 = 26 mg/L (nom., Desmodesmus subspicatus, pH-adjusted; read-across: CAS 102-71-6)
Toxicity to aquatic microorganisms
The inhibition of the degradation activity of activated sludge is not anticipated when the substance is introduced in appropriately low concentrations.
16-h EC10 = 171 mg/L (nom., P. putida)
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
