Description of key information
The short-term toxicity to aquatic invertebrates of the test substance, TM11-0230, was assessed according to OECD Test Guideline 202 using an immobilisation method. Daphnids (20/concentration, 4 replicates of 5 animals) were exposed to nominal concentrations ranging from 1.0, 1.8, 3.2, 5.6 and 10 mg/L.The experimental was under static exposure conditions over a period of 48 hours. The measured concentrations of FRET 11 -0230 ranged between 88 and 94% of their nominal values in samples of 3.2, 5.6 AND 10 mg/l test solutions at 0 and 48 hours. The study met the acceptability criteria prescribed by the protocol and was considered valid. The 48 h EC50 was 5.6 mg/L with 95 % confidence limits of 5.0 - 6.4 mg/L. The NOEC was 3.2 mg/L and the LOEC was 5.6 mg/L.
