Conclusion on classification

The substance does not meet the criteria for acute hazard classification toward the aquatic environment, in accordance with the criteria set in Regulation (EC) No 1272/2008 (CLP). The substance meets the criteria for chronic hazard classification toward the aquatic environment, the substance is classified as, Aquatic Chronic Category 2. The endpoints used for the derivation of the classification can be seen below.

Endpoints used for hazard assessment:

Fish 96h LC50: 3.601 mg/L (Anon., 2018)

Daphnid 48h EC50: 3.046 mg/L (Anon., 2018)

72h EC50 (growth rate): 1.166 mg/L (Anon., 2018)

72h EC10 (growth rate): 0.657 mg/L (Anon., 2018)

The following are considered for classification & labelling (GHS Rev7 & CLP (1272/2008)):

Data used for assessment: Acute algae toxicity

72h EC50 (growth rate): 1.166 mg/L (Anon., 2018)

72h EC10 (growth rate): 0.657 mg/L (Anon., 2018)

Substance Rapidly Degradable: No (28d biodegradation = 0 %, Anon., 2006; OECD 310)
