Additional information

The effect of the substance on green algae Desmodesmus subspicatus was investigated in one GLP and three non-GLP screening tests according to OECD guideline 201. At test termination after 72 h, an EC50 > 100 mg/L and a NOEC of >= 100 mg/L nominal was determined in the GLP study (RCC Ltd., 2005). In the screening tests the EC50 was above 100 mg/L, whereas a NOEC was not determined as it was not the purpose of such a test type (RCC Ltd 2005).
