Description of key information

GLP-compliant guideline study available assessing acute toxicity to algae in freshwater.

Key value for chemical safety assessment

EC50 for freshwater algae:
100 mg/L
EC10 or NOEC for freshwater algae:
22 mg/L

Additional information

Based on the results of the study observed in the acute algal toxicity study, it can be concluded that LiPF6 is of low/moderate toxicity to algae: 72h EC50 > 100mg/l. Effects on growth rate were observed during the study: NOEC 22 mg/l. This result is fully compatible with the reported low/moderate toxicity of fluoride and lithium to freshwater algae (two different algal 96h biomass EC50 values, 43 and 122 mg F-/l cited in HF: EU Risk Assessment Report, 2001. Lithium bromide algal growth rate 72h EC50 290 mg/l, NOEC 10 mg/l: Japan MoE 2001).
