Additional information
Conclusion on classification
Classification related key information:
Biodegradation in water: Not readily biodegradable (11.3 % after 28d)
Bioaccumulation: Log Kow = 2.73
Aquatic acute toxicity:
- to Fish: LC50 (96 h) = 9.7 mg/L (meas. TWA) for Oncorhynchus mykiss (OECD 203)
- to aquatic invertebrates: EC50 (48 h) = 3.403 mg/L (measured) for Daphnia magna (OECD 202)
- to algae: ECr50 (72 h) = 5.59 mg/L (meas. TWA) for Raphidocelis subcapitata (OECD 201)
Aquatic chronic toxicity:
- to Fish: NOEC (35 d) ≥0.11 mg/L (meas. TWA) for Danio rerio (OECD 210)
- to aquatic invertebrates NOEC (21d) = 0.45 mg/L (meas. TWA) for Daphnia magna (OECD 211)
- to Algae: NOEC (72h) = 1.61 mg/L (meas. TWA) for Raphidocelis subcapitata (OECD 201)
CLP:
According to the data listed above the test substance is not rapidly biodegradable (11.3 % after 28 d) and has a low potential to bioaccumulate (log Kow < 3). The most sensitive acute effect was obtained for Daphnia magna with an EC50 (48 h) of 3.403 mg/L. The most sensitive chronic effect was the reported NOEC (21d) of 0.45 mg/L in a chronic toxicity study with Daphnia magna. Based on the available data the substance needs to be classified and labelled as Aquatic Chronic 2.
