Environmental fate and pathways
Not readily biodegradable (5.99% in 28 d, OECD 301 D)
log Kow = 4.11 (OECD 107, EU method A.8)
Aquatic short-term toxicity
EC50 (48 h) = 4.7 mg/L (nominal, OECD 202, D. magna)
ErC50 (72 h) = 4.42 mg/L (nominal, OECD 201, P. subcapitata)
LC50 (96 h) = 2.39 (nominal, OECD 203, O. Latipes)
Aquatic long-term toxicity
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.
