Description of key information

The test substance induced no visible effects in carp at or below 1.8 mg/L (NOEC).

The 96h-LC50 was 2.4 mg/L (95% confidence interval between 1.8 and 3.3 mg/L).

Key value for chemical safety assessment

LC50 for freshwater fish:
2.4 mg/L

Additional information

In a 96-h acute toxicity study conducted according to OECD guideline 203 and GLP, carp (Cyprinus carpio) were exposed to the test substance under flow-through conditions at the following nominal concentrations: 0 (blank-control), 1, 1.8, 3.2, 5.6 and 10 mg/L. The 96h-LC50 was 2.4 mg/L based on average concentrations of the stock solutions (95% CL between 1.8 and 3.3 mg/L). The study is considered to be reliable without restrictions.
