Additional information
In a static exposure test on the toxicity of the feshwater algae Scenedesmus subspicatus over 72 hours at concentrations of 0, 1.56, 3.13, 6.25, 12.5, 25, 50 and 100 mg/L (undissolved test substance removed by filtration), following OECD guideline 201, as performed by BASF AG (2000), the ErC50 (72h) was estimated to be >100 mg/L and the NOEC (72h) was estimated to be >=100 mg/L.
his is in line with the results of a OECD 29 test: The transformation/dissolution concentrations of the anorganic building blocks Cr and Sb at a loading rate of 100 mg/L are far below of the acute ERVs.
