Description of key information

With high probability acutely not harmful to aquatic invertebrates.

Key value for chemical safety assessment

Additional information

The results of a semi-static exposure test on the toxicity of the substance to Daphnia magna, performed over 48 hours as a limit test (100 mg test substance were dispersed in 100 mL, not dissolved; test solution used without filtration) following OECD guideline 202 as conducted by MOE (2001) and a static exposure test on the toxicity of the substance to Daphnia magna as performed by BASF AG (1999) over 48 hours, following EU method C.2, Directive 92/32 EEC at concentrations of 0, 12.5, 25, 50, 100 mg/L (undissolved test substance removed by centrifugation), indicate that the test substance has no toxic effects in the range of its water solubility.

This is in line with the results of a OECD 29 test: The transformation/dissolution concentrations of the inorganic building blocks Ni and Sb at a loading rate of 100 mg/L are far below of the acute ERVs.
