Conclusion on classification

Environmental fate and pathways

Biodegradation

Not readily biodegradable (5.99% in 28 d, OECD 301 D)

Bioaccumulation

log Kow = 4.11 (OECD 107, EU method A.8)

 

Aquatic short-term toxicity

Aquatic invertebrates

EC50 (48 h) = 4.7 mg/L (nominal, OECD 202, D. magna)

Aquatic algae

ErC50 (72 h) = 4.42 mg/L (nominal, OECD 201, P. subcapitata)

Fish

LC50 (96 h) = 2.39 (nominal, OECD 203, O. Latipes)

Aquatic long-term toxicity

Aquatic algae

ErC10 (72 h) = 1.53 mg/L (nominal, OECD 201, P. subcapitata)

 

Conclusion on CLP

Short-term effect values are available for all three trophic levels and one long-term effect value is available for aquatic algae. All EC/LC50 values for acute toxicity are in the same order of magnitude and > 1 mg/L. Therefore, the substance is not classified as acutely hazardous to the environment. However, the EC/LC50 values are > 1 to ≤ 10 mg/L and the substance is not readily biodegradable according to OECD criteria and has a log Kow of 4.11. Therefore, the substance is classified and labelled as Category Chronic 2 for long-term environmental hazards, according to the consolidated version of Regulation (EC) No 1272/2008 and further amendments.
