Conclusion on classification

Short-term toxicity EC/LC50 values of Sr available for 3 trophic levels are situated between >40.3 mg Sr/L and >125 mg Sr/L, corresponding to > 72.9 mg/L and 226.2 mg/L strontium chloride based on an average Sr content of 55%. In accordance with Regulation (EC) No 1272/2008, Table 4.1.0 (a), classification for acute aquatic hazard is not required for strontium hydroxide as all EC50/LC50 values are above the classification criteria of 1 mg/L.

Long-term toxicity data are available for three trophic levels and range from 21 mg Sr/L to ≥ 43.3 mg Sr/L, corresponding to 38.0 mg/L and 78.3 mg/L strontium chloride based on an average Sr content of 55%. In accordance with Regulation (EC) No 1272/2008, Table 4.1.0 (b) (i), classification for chronic aquatic hazard is not required for strontium hydroxide as all chronic EC10/NOEC values are above the classification criteria of 1 mg/L.
