Description of key information
In a 48 h acute toxicity study conducted according to OECD guideline 202, water fleas (Daphia magna) were exposed to the registered substance URACROSS ZW7672P, Product ID 021116/000. The 48h-EC50 was above the solubility limit of the test substance in test medium. The study is considered to be reliable without restrictions.

Additional information
In a 48 h acute toxicity study conducted according to OECD guideline 202, water fleas (Daphia magna) were exposed to the registered substance URACROSS ZW7672P, Product ID 021116/000 under static conditions at the following nominal concentrations: 0 (blank control), 1.0. 10 and 100 mg/L WAFs. Analysis of the samples taken from the WAF prepared at 100 mg/L at the start of the test showed measured concentrations of 1.0 mg/L in test medium. The measured concentration remained stable during the exposure (86% of initial). It should be noted that the maximum water solubility of the registered substance URACROSS ZW7672P, Product ID 021116/000 is < 8 μg/L. As no biologically significant immobilisation (i.e. >10%) was observed at any of the groups tested, the 48h-EC50 was above the solubility limit of the test substance in test medium. The study is considered to be reliable without restrictions.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
