Conclusion on classification

Environmental fate and pathways

Degradation

Not readily biodegradable (12.43% within 28 d, BODIS test)

Bioaccumulation

BCF = 222 L/kg in RT- S9 system (Rainbow Trout liver S9 subceluular fraction.

Short-term aquatic toxicity

Fish

No effects up to saturation level (LC50 (96 h) > 0.999 mg/L, geom. mean measured, OECD 203, D. rerio)

Aquatic invertebrates

EC50 (48 h) = 0.696 mg/L (geom. mean measured, OECD 202, D. magna)

Aquatic algae

No effects up to saturation level (ErC50 (72 h) > 1000 µg/L, geom. mean measured, 100% saturated solution, OECD 201, P. subcapitata)

 

Long-term aquatic toxicity

Aquatic algae

No effects up to saturation level (ErC10 (72 h) > 1000 µg/L, geom. mean measured, 100% saturated solution, OECD 201, P. subcapitata)

 

Conclusion on CLP

Aquatic invertebrates are the most sensitive trophic level for short-term aquatic toxicity. No acute effects were observed toward fish and aquatic algae up to the saturation limit (0.999 mg/L, 1000 µg/L). No long-term aquatic toxicity to aquatic algae was recorded up to the saturation limit (1000 µg/L). Furthermore, the substance is not rapidly biodegradable. Based on the available data, the substance is classified and labelled as Acute 1 and Chronic 1 for environmental hazards, according to the consolidated version of Regulation (EC) No 1272/2008 and further amendments (ATPs).
