Conclusion on classification

Aquatic acute toxicity
96 h, LC50 (Danio rerio): >
0.32 mg/L (equivalent to > 100 mg/L nominal concentration), based on results obtained in a preliminary study with the read across substance Blue Sema, CAS 1040873 -93 -5
48 h, EC50 (Daphnia magna): > 0.45 mg/L (geometric mean measured; solubility limit of the test item in the test medium, corresponding to a nominal loading rate of 100 mg/L)
7 d, EC50 (growth rate based on frond number and dry weight) (Lemna gibba): >0.305 mg/L (time-weighted mean measured concentration; solubility limit in the test medium; nominal 25 mg/L)

Aquatic chronic toxicity
7 d, NOEC (growth rate based on frond number and dry weight) (Lemna gibba): 0.305 mg/L (time-weighted mean measured concentrations; solubility limit in the test medium; nominal 25 mg/L)

 
Biodegradation:
The substance was not readily biodegradable by OECD criteria (9.9 % biodegradation on day 28).

Partition coefficient:
Log Pow < -0.3 at 20 °C.

No lethal or sub-lethal effects for invertebrates and no significant inhibition of growth rate and yield of Lemna gibba were detected up to the solubility limit of the test item in the test media.

Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. Up to the solubility limit of the test item no effects were shown. In combination with the low Pow, the substance is not considered to be classified as hazardous for aquatic toxicity under Regulation (EC) No 1272/2008,as amended for the twelfth time in Regulation (EU) 2019/521.
