Description of key information
With high probability acutely not harmful to aquatic invertebrates.
No acute effects occurred on the waterflea Daphnia magna (OECD 202) in the range of water solubility; EC50 (24h) > 86 mg/L (measured)
Key value for chemical safety assessment
Additional information
The acute toxicity to aquatic invertebrates was investigated with the waterflea Daphnia magna according to OECD guideline 202 [CIBA-GEIGY 1985]. Due to the low water solubility of the test item a solubilizer was used to prepare the stock solution. The highest nominal test concentration was 100 mg/L, which corresponds with an analytically verified concentration of 86 mg/L. After the 24 hours test duration 20% of the daphnids were immobilized at the highest test concentration of 86 mg/L, whereas no effects were observed at the next lower concentration of 32 mg/L (measured). Since the measured concentrations clearly exceeded the water solubility of the test substance, it can be stated that there is no toxicity in the range of the water solubility (< 0.1 mg/L) . Therefore, the test substance is considered not to be acutely harmful to aquatic invertebrates.
