Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Short-term and long-term aquatic toxicity studies have been performed on species from three trophic levels. The end-points are presented, as follows :

Acute Fish (O. mykiss gill cells):

LC50 = 1.89 mg/L

NOEC = 0.97 mg/L

Acute Daphnia Immobilisation (D. magna) :

48hr EC50 = 0.076 mg/L

48hr EC0 = 0.029 mg/L

Algal Inhibition (P. subcapitata) :

72 hr ErC50 > 0.11 mg/L

72 hr ErC10 = 0.028 mg/L

72 hr NOErC = 0.023 mg/L

72 hr EyC50 = 0.072 mg/L

72 hr EyC10 = 0.040 mg/L

72 hr NOEyC = 0.023 mg/L

Long-Term Fish (P. promelas) :

NOEC > = 0.79 mg/L

Long-Term Freshwater Invertebrate (C. dubia) :

NOEC = 0.1 mg/L

The most sensitive species from the long-term studies is algae with an ErC10 of 0.028 mg/L. The PNEC-freshwater based on the available data is, therefore, 2.8 ppb (i.e. 0.028 mg/L with an Assessment Factor of 10 applied).
