Additional information

PNECs were derived from the most sensitive test available for each compartment/endpoint.

Conclusion on classification

Acute toxicity:

Algae is the most sensitive species with an EC50 value of >1.58 mg/L (growth rate). According to 67/548/EEC and Regulation (EC) No 1272/2008 (CLP, GHS) the subsatnce has not to be classified regarding acute toxicity to the environment as the lowest LD50 value is above 1 mg/L.

Chronic toxicity:

Algae is the most sensitive species with an acute EC50 of > 1.58 mg/L (growth rate). As the substance is not regarded to be ready biodegradable the substance has to be to be classified regarding chronic toxicity with N, R51/53 (Dangerous for the environment; Toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment.) according to directive 67/548/EEC and chronic env. tox. cat. 2 (H411: Toxic to aquatic life with long lasting effects.) according to Regulation No (EC) 1272/2008 (CLP/GHS).
