Description of key information
Additional information
Information about other aquatic organisms is not required under Regulation (EC) No 1907/2006 but to complete the data set additional informations are provided.
Eastern oysters (Crassostrea virginica) were exposed under flow-through conditions for 96 hours
to six mean measured concentrations of the test substance ranging from 0.062 to 1.8 mg a.i./L. The test was conducted at concentrations near the functional limit of solubility of the test substance in a saltwater system. There were no mortalities or clinical signs of toxicity observed at any concentration tested. Based on inhibition of shell deposition, the 96-hour EC50 value was 1.0 mg a.i./L, with a 95% confidence interval of 0.71 to 1.2 mg a.i./L. The NOEC was determined to be 0.47 mg a.i./L.
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.
