Key value for chemical safety assessment

Additional information

As the result of analysis at 0 hours, the concentration of AM19 in test solution was 95.4 mg/l. there was 95.4 % of nominal concentration.

The concentration at 48 hours was 89.8 mg/l. There was 89.8 % of nominal concentration.

The geometric mean of concentration was 92.6 mg/l during the test periods.

The limit test was conducted in measured concentrations of 92.6 mg/l. After 24 hours and 48 hours exposure, no daphnia was immobilized in 92.6 mg/l of test solution. The 24 hours and 48 hours -EC50 value of AM19 daphnia magna was investigated as > 92.6 mg/l. The NOEC was 92.6 mg/l at 24 and 48 hours. Determination of LC50 and NOEC were based on measured concentration.
