Long-term toxicity to fish

Description of key information
Based on the findings in a fish, early-life stage toxicity test (OECD 210) and the analytical results of the associated solubility study in ISO water, the substance is considered non-hazardous to fish, also following long-term exposure. No mortality/effects on hatchability was observed up to the highest concentration tested (320 µg/L nominal). Reduction of body weight and length of fish was seen at 12.8, 64.0 and 320 µg/L. However, considering the maximum substance solubility of 0.0322 µg/L, being two orders of magnitude lower than the concentrations applied (the analytical method applied in the test quantified the sum of dissolved and particular matter) showing effects, it is obvious that effects seen were attributable to particulate matter affecting fish growth by physical effects rather than toxicological effects. This is also supported by the observations of precipitations made visibly during the study at nominal concentrations of 12.8 µg/L and above.

Additional information
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.
