Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Two good quality studies were available for two fish species. The lowest NOEC was observed for Oreochromis mossambicus: 1951.9 µg total In/L (single measured value). The NOEC for Pimephales promelas was 25000 µg total In/L. The discrepancy between the two studies is that a high loading of In (i.e. >15 mg In/L) results in a pH-shift. The study performed by Aecom (2012a) buffered the pH whereas Lin and Hwang did not report or buffer pH. This could lead to a pH drop which could contribute at the lower NOEC observed in the Lin and Hwang (1998) study compared to the Aecom study (2012a).

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.
