Additional information
The acute immobilization effect of the test item FAT 40866/A TE was studied on Daphnia magna. TheDaphnia magna less than 24 hours old were exposed to a limit concentration of 100 mg/L of FAT 40866/A TE along with a negative and a positive control in reconstituted water at 20.5 – 20.8°C. The number of Daphnia immobilized was recorded at 24 and 48 hours post exposure.
There was no immobilization of Daphniain the negative control and 60 % immobilization of Daphnia was observed in the positive control at 48 hours post exposure. There was 0 % immobilization of Daphnia at 48 hours post exposure at the limit concentration of 100 mg/L of FAT 40866/A TE.
The EC50 value for FAT 40866/A TE at 48 hours was more than 100 mg/L.
On the basis of the observations made during this test, the NOEC (which is the highest tested concentration of test item at which no effects on Daphnia were observed) was more than the maximum tested concentration of 100 mg/L.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
