Additional information

The acute toxicity to fish was assessed in a 96-h toxicity study according to OECD guideline 203 and EU method C.7 under GLP conditions. After a range-finding test, a limit test was performed with carp (Cyprinus carpio) exposed to 100 mg/L in a static system. Samples for analysis were taken at the start and the end of the test. Analysis of the samples taken during the final limit test showed that the measured concentration was in agreement with the nominal concentration. No visible effects occurred during the 96-hour test period. Hence, the 96h-LC50 for carp exposed to the test substance was > 100 mg/L, the maximum concentration to be tested. (NOTOX B.V., 1998)
