Description of key information
This study investigated the effects of exposure to a saturated solution of FAT 40543/A on survival and reproductive performance in Daphnia magna during 21 days of exposure.
FAT 40543/A had no effect on the survival or reproduction of Daphnia magna during prolonged exposure to 0.10 mg/l (NOEC), the maximum attainable concentration under the conditions applied during the present test.
Key value for chemical safety assessment

Additional information
In a study the effects of exposure to a saturated solution of FAT 40543/A on survival and reproductive performance in Daphnia magna during 21 days of exposure was investigated. The study was performed semi-static with renewal of water every 48 hours. Whereas maximum concentration at beginning of renewal was slightly above 0.1 mg/L the concentration decreased significantly until the next renewal phase. However, overall the concentration of saturated solution was on average 0.1 mg/L. In parallel 50% saturated solution was tested next to a control and a treatment control. Highest mortality on parental animals was seen in the treatment control and thus any effects on mortality by the test substance can be excluded. Similarly, reproductive performance of the two treatment concentrations was not significantly different from the two controls and thus also no effect on reproduction was noted.
In conclusion, FAT 40543/A had no effect on the survival or reproduction of Daphnia magna during prolonged exposure to 0.10 mg/l (NOEC), the maximum attainable concentration under the conditions applied during the present test.Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
