Additional information

Conclusion on classification

Environmental fate and pathways

Degradation

Not readily biodegradable: 11% and 20% after 28 d (OECD 301B)

Bioaccumulation

Log Kow = < -5.1 at 19.9 °C (OECD 107, estimation method).

 

Aquatic acute toxicity

Fish

LC50 (96 h) = 6.4 mg/L (nominal, Standard methods for the Examination of Water and Wastewater, 13 th Edition, USA, Pimephales promelas)

Aquatic invertebrates

EC50 (48 h) = 3.2 mg/L (nominal, OECD 202, Daphnia magna)

Algae

EC50 (7 d) = 0.4 mg/L (yield, Selenastrum capricornutum, modification of the provisional algal assay procedure (PAAP)) 

Classification according to CLP

Based on the data above the substance is not rapidly degradable and has a low potential for bioaccumulation. Based on the data for aquatic toxicity the substance needs to be classified and labelled as Acute Cat. 1 (H400) and Chronic Cat. 1 (H410) for environmental hazard according to the consolidated version of Regulation (EC) No 1272/2008 (dated: 01.01.2017) and further amendments (ATPs).

M-factor for acute aquatic toxicity: 1
