Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Toxicity to terrestrial arthropods

Description of key information
No key information has been identified to cover this endpoint. However, since the outcome of the CSA using the current PNECsoil did not indicate the need to refine the terrestrial hazard assessment, further testing is not required.
Key value for chemical safety assessment
Additional information
A single study was identified as containing relevant and reliable information on toxicity to terrestrial arthropods. In the study of Li et al. (2006), beetle larvae (Holotrichia parallela) were exposed to soil spiked with ReCl3.6H2O (Ce, La, Pr) for about a year until adult eclosion. No effects on mortality, pupation and emergence were observed up to the highest dose tested, which was 3000 mg/kg soil (ReCl3.6H2O). The recalculated NOEC is therefore 1180 mg/kg soil (based on total RE elements Ce + La + Pr). This study is not sufficient to cover this endpoint because it only presents results from a mixed exposure experiment. However, the results can be considered as indicative concerning the severity of lanthanum toxicity in soil arthropods.
Since the outcome of the CSA using the current PNECsoil did not indicate the need to refine the terrestrial hazard assessment, further testing is not required.
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.
