Short-term toxicity to aquatic invertebrates

The test item FAT 40840/A TE had no acute toxic effects on Daphnia magna up to and including the nominal test concentration of 100 mg/L under the present test conditions.

Short-term toxicity to algae

FAT 40840/A TE had a significant inhibitory effect on the growth (yield) of Scenedesmus subspicatus after the test period of 72 hours at the test concentrations of 2.1 mg/L (72-hour LOEC) and at all higher test concentrations. The 72-hour NOEC was determined to be 0.52 mg/L, since at this test concentration the growth rate and yield were not significantly lower than in the control.

Toxicity to microorganism

The test item FAT 40840/A TE had no significant inhibitory effect (≤15%) on the respiration rate of activated sludge after the incubation period of 3 hours at the limit test concentration of 1000 mg/L.
