Additional information

In a GLP, 72-hour static test with the green alga Desmodesmus subspicatus according to OECD guideline 201, the algae toxicity was investigated (BASF AG, 2003; report no. 01/0525/60/1). Statistical evaluation of the endpoint growth rate revealed a 72 -h ErC50 of 19 mg/L and a 72 -h ErC10 of 11.2 mg/L, related to the analytically verified nominal concentrations.
