Additional information

A 96-hour LC50value of >71 mg/l and a NOEC of ≥71 mg/l have been determined for the effects of the registered substance on mortality of Brachydanio rerio based on geometric mean measured concentrations. The corresponding nominal exposure concentration was 100 mg/l. It is likely that the test organisms were exposed to a mixture of parent substance and hydrolysis products. The results are assessed on the basis of nominal concentrations because it is not possible to establish the identity of the substance(s) that the analysis relates to (see section 7.1.1).
