Additional information

Acute tests evaluating the toxicity of the test substance to aquatic organisms are available for three different trophic levels. No effects were observed up to a nominal concentration of 100 mg/L (nominal) in the available studies with fish, aquatic invertebrates and algae.

The test substance did not cause inhibition of biodegradation in a study according to EU Method C.4-E with activated sludge microorganisms. A NOEC (14 d) of ≥ 2.9 mg/L was derived. Significant inhibition of the subsequent degradation process in sewage treatment plants is not expected.
