72 h, IC50 (Desmodesmus subspicatus): 7.66 mg/L (nominal concentration)

 

Aquatic chronic toxicity

21 d, NOEC (Daphnia magna): 0.02 mg/L (nominal concentration)

72 h, IC10 (Desmodesmus subspicatus): 0.81 mg/L (nominal concentration)

 

Biodegradation: Not readily biodegradable, no degradation after 28 days

Classification, Labelling, and Packaging Regulation (EC) No 1272/2008

Acute aquatic data for the test item are available from three trophic levels. The most sensitive species was determined to be Daphnia magna, with a key EC50 of 0.56 mg/L. The test item is therefore classified as acute aquatic toxicity category 1 with an M factor of 1, according to CLP Regulation (EC) No 1272/2008 (8th Adaptation to Technical Progress).

Chronic toxicity data are available for algae and aquatic invertebrates. Daphnids were the most sensitive species, with a NOEC of 0.02 mg/L for effects on reproduction and body length. As the substance is not rapidly degradable, the test item classified as chronic aquatic toxicity category 1 with an M factor of 1, according to CLP Regulation (EC) No 1272/2008 (8th Adaptation to Technical Progress).
