Description of key information
The 48-h EC50 of Daphnia magna expsoeed to the test item was estimated to be higher than a loading rate of 100 mg/L.
Key value for chemical safety assessment
Additional information
The acute toxicity to aquatic invertebrates was assessed in two studies according to OECD guideline 202 and EU-method C.2.
In the first study (ECT 2006) daphnids were exposed to a loading rate of 100 mg/L for 48 hours under static conditions. The 48-hour NOEC and the 48-hour EC0 of the test item toDaphnia magna were determined at a nominal concentration of 100 mg/L (mean measured 0.12 mg/L). The 48 -hour EC50 and the 48-hour EC100 were determined to be greater than 100 mg/L nominal concentration (mean measured 0.12 mg/L).
In the second study (Bayer, 1999) no effect on Daphnia magna in the presence of a weighed-in quantity of 1 mg/L of the test item was observed.
The results of both studies demonstrate no toxic effects of the test item at the range of the water solubility.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
