Additional information
PNECs were derived from the study with the most sensitive species available for each compartment/endpoint.
Conclusion on classification
Acute aquatic toxicity
Algae were the most sensitive species in acute toxicity tests with lithium bis(oxalato)borate, according to EU method and OECD guideline, resulting in a 72 -hour EC50 of 40.69 mg/L. Based on acute aquatic toxicity results obtained, LiBOB was not classified and labelled according to Directive 67/548/EC (DSD) and Regulation (EC) No 1272/2008 (CLP).
Chronic toxicity:
Algae were the most sensitive species in chronic toxicity tests with lithium bis(oxalato)borate, according to EU method and OECD guideline, resulting in a 72 -hour EC 50 for growth rate was 40.69 mg/L and 72 -hour NOEC 10 mg/L. This result is in line with the chronic toxicity data for fish (NOEC 28-d 20 mg/L) and for daphnia (EC10 21-d 19 mg/L). LiBOB was shown to be ready biodegradable.
Based on chronic aquatic toxicity results obtained, LiBOB was not classified and labelled according to Directive 67/548/EC (DSD) and Regulation (EC) No 1272/2008 (CLP).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
