Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
Information obtained on soluble InCl3 is considered relevant for the combined ecotoxicity of the In3+ ion and In(OH)3 complexes. It is therefore also used for the general conservative assessment of the acute ecotoxicity of In metal (powder). Given the proven lack of solubility and, consequently, aquatic ecotoxicity of In metal powder (see results on chronic testing with C. dubia and P. subcapitata), this general approach must be considered as very conservative.
One good quality short-term test was available. Lin and Hwang (1998) tested the toxicity of InCl3 on 3 -day-old larvae of
Oreaochromis mossambicus. The LC50 observed on Oreochromis mossambicus is 19519 µg total In/L. Lin and Hwang (1998) did not measure pH; whereas high loading with In in these ecotoxicity tests (>15 mg In/L) could result in a pH-drop, which could contribute to the observed ecotoxicity.
One study in marine waters on Sillago japonica was available (LC50 >20mg/l; Onikura et al. 2008).

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.
