Additional information

Conclusion on classification

Key information for classification

Biodegradation: Readily biodegradable (84% degradation after 28d based on CO2 evolution; OECD 301 B)

Bioaccumulation: log Pow 4.31 -10.23 (QSAR calculation based on Meylan/Kowwin LogP Model version 1.1.4.).

Aquatic acute toxicity

- Fish (freshwater): LC50 (96 h) >0.536 mg/L (Danio rerio, OECD 203, mean measured, mortality)

- Aquatic invertebrates (freshwater): EC50 (48 h) 1.11 mg/L (Daphnia magna, OECD 202, based on time weighted average)

- Algae (freshwater): ErC50 (72 h) 0.243 mg/L (Desmodesmus subspicatus, OECD 201, based on geometric mean measured concentrations)

Aquatic chronic toxicity

- Algae (freshwater): ErC10 (72 h) 0.1767 mg/L (Desmodesmus subspicatus, OECD 201, based on geometric mean measured concentrations)

 

Conclusion on Classification

Based on the data above, the substance is considered to be rapidly degradable in the environment. Algae were the most sensitive organisms in the available experimental data with an acute ErC50 (72h) of 0.243 mg/L and a chronic ErC10 (72 h) of 0.177 mg/L. Based on the availble data the substance is classified and labelled as Acute Cat. 1 (H400) and Chronic Cat. 3 (H412) for environmental hazard according to the consolidated version of Regulation (EC) No 1272/2008 (dated: 01.01.2017) and further amendments (ATPs).
