Description of key information

With high probability acutely not harmful to aquatic invertebrates. No acute toxic effects occur within the range of solubility.

Key value for chemical safety assessment

Additional information

One GLP guideline study on the toxicity of the substance to Daphnia magna is available (RCC Ltd. 2002c). Due to the low water solubility of the test item, a supersaturated dispersion of the test item with a loading rate of 100 mg/L was tested. The undiluted filtrate with the maximum concentration of dissolved test item was used as the test medium in a static test system set up according to OECD guideline 202. In the control and at the loading rate of 100 mg/L no immobilization or other signs of intoxication were determined during the test period of 48 hours.Therefore, an EC50 > 100 mg/l based on the loading rate was determined after 48 hours.
