Conclusion on classification

Acute aquatic toxicity classification:

Short-term E/LC50 values are available for algae (growth rate 72hEC50 = 16.1 mg/L), daphnia (48hEC50 = 18.2 mg/L) and fish (96hLC50 > 100 mg/L). The lowest EC50 is obtained in the algae toxicity test showing that the substance is harmful to the aquatic organisms. The EC50 obtained with daphnia triggers the same conclusion.

Therefore, Lithium Cryolite is not classified for acute aquatic toxicity according to the CLP criteria.

Chronic aquatic toxicity classification:

Chronic toxicity data are available for algae showing a 72hNOEC = 7.57 mg/L. Therefore, no chronic aquatic classification is applicable based on the algal toxicity data.

No chronic toxicity data are available for daphnia and fish. Therefore, the acute data are used in combination with the biodegradability and bioaccumulation potential of the substance. As Lithium Cryolite is an inorganic substance, no biodegradability and logkow measurements are possible. As a worst case approach, this inorganic substance is considered as not readily biodegradable.

Based on this information, Lithium Cryolite is classified as chronic aquatic toxicity category 3, H412, according to the CLP criteria.
