Additional information
- Short-term toxicity to aquatic invertebrates: Weight of evidence. One study available. Method according to OECD TG 202 / EU Method C.2, GLP study. In accordance to a range-finding preliminary study, the concentrations of 0.69; 1.38; 2.76; 5.52; 11.05; 22.10 and 44.20 mg/l test item (nominal) were used. Twenty Daphnia magna (< 24 h old, 5 per replicate) were exposed to either a control medium or the test item concentrations specified for 48 hours under static conditions. No analytical monitoring was performed. The validity criteria were fulfilled. Based on the results obtained, the 48h-EC50 value of the test item on Daphnia magna is 8.953 mg/L. No NOEC value was obtained. Furthermore, according to a calculation by ECOSAR v1.11 model, the LC50 of the test item on daphnia is 1.965 mg/L.
- Toxicity to aquatic algae and cyanobacteria: Weight of evidence. Method according to OECD TG 201 / EU Method C.3, GLP study. In accordance to a range-finding preliminary study, the concentrations of test item of 0.2; 0.5; 0.9; 1.8; 3.7; 7.4; 14.7 and 29.4 mg/l test item (nominal) were used. Three replicates were exposed to concentration, and six replicates were exposed to the control medium, for 72 hours under static conditions. No analytical monitoring was performed. The validity criteria were fulfilled. Based on the results obtained, the 72h-EC50 value of the test item on Pseudokirchneriella subcapitata is 0.81 mg/L. No NOEC value was obtained. Furthermore, according to a calculation by ECOSAR v1.11 model, the LC50 of the test item on algae is mg/L.
Conclusion on classification
Based on available data (48h-EC50 in Daphnids = 8.953 mg/L, 72h-EC50 in algae = 0.81 mg/L), the test item is classified for aquatic toxicity as Aquatic Acute 1, H400, and Aquatic Chronic 2, H411, according to CLP Regulation (EC) No. 1272/2008.
