Additional information
Conclusion on classification
The substance does not meet the criteria for acute aquatic hazard classification. The subtance meets the chronic hazard classification, Chronic Cat. 2, toward the aquatic envionrment, in accordance with the criteria set in Regulation (EC) No 1272/2008 (CLP) and GHS rev. 7 (2013).
Endpoints used for hazard assessment:
Fish 96h LC50: 5.9 mg/L (Squance, 2018)
Daphnid 48h EC50: 4.2 mg/L (Squance, 2018)
Algae 72h EC50 (growth rate): 1.6 mg/L (Vyrenhoef, 2018)
Algae 72h EC10 (growth rate): 0.23 mg/L (Vyrenhoef, 2018)
The following are considered for classification & labelling (GHS Rev. 7 & CLP (1272/2008)):
Data used for assessment: Acute algae toxicity (worst-case)
72h EC50 (growth rate): 1.6 mg/L (Vyrenhoef, 2018)
72h EC10 (growth rate): 0.23 mg/L (Vyenhoef, 2018)
Substance Rapidly Degradable: No (28d biodegradation = 92.9 % but does no meet the 10 -day window, Best, 2017)
Log Kow: 3.80 (Butler, 2018)
