Description of key information
At present, no study is available that can be considered as a key study or can cover the endpoint in any other way (e.g., several studies in a weight of evidence approach). The outcome of the CSA indicates that at this point in time there is no need for further testing for this endpoint.
Key value for chemical safety assessment
Additional information
Only one study was identified as containing relevant and reliable information on this endpoint (Bogers, 1995). In this study, carp (Cyprinus carpio) were exposed for 21 days to LaCl3, yielding a 21-d NOEC (based on mortality) of 0.26 mg La/L and a 21-d LC50 of > 5 mg La/L, based on geometric means of measured dissolved La concentrations. This study was however performed according to OECD guideline 204 (Fish, Prolonged toxicity test), which is insufficient to cover this endpoint in the absence of real long-term studies. The study lasted one week longer than recommended by the guideline (i.e., 21 instead of 14 days), however, since only mortality was studied as endpoint, the study can only be considered as a supporting study. Further testing is however not considered necessary since the outcome of the CSA does not indicate the need for it.
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.
