Additional information

One GLP guideline study, performed by BASF (2008) on freshwater algae (Desmodesmus subspicatus) is available.The 72 hour EC50 values for Bismutvanadat BiVO4 (Pigment Yellow 184) is > 100 mg/L based on the loading concentration of the test substance. The test substance had no observable inhibitiory effect on the growth of Desmodesmus subspicatus up to the saturation limit in test media under the test conditions. A slight stimulatory effect on algal growth was observed at 10 and 100 mg/L.
