log Kow = 3.11 (EU method A. 8, 22.7 °C, HPLC method)

 

Aquatic acute toxicity

Aquatic invertebrates

EL50 (48 h) = 15.7 mg/L (nominal loading rate, OECD 202, D. magna)

Aquatic algae

ErL50 (72 h) = 20.2 mg/L (nominal loading rate, OECD 201, P. subcapitata)

Aquatic chronic toxicity

Aquatic algae

ErL10 (72 h) = 8.18 mg/L (nominal loading rate, OECD 201, P. subcapitata)

 

Classification according to CLP

Acute effect concentrations are available for two trophic levels (aquatic invertebrates and algae) and are of the same order of magnitude in the range between 10 and 20 mg/L. Since both E(r)L50 values are clearly > 1 mg/L the substance is not classified for short-term hazards to the aquatic environment. Based on the lowest acute effect value of 15.7 mg/L for aquatic invertebrates and the fact that the substance is not readily biodegradable, the substance is classified and labelled as Chronic 3 for the long-term hazards to the aquatic environment, according to the consolidated version of Regulation (EC) No 1272/2008 and further amendments (ATPs).
