Additional information

From the various models available using ChemProp, estimations for aquatic toxicity values are not available. Therefore, we tested for structural alerts that indicate toxicity to aquatic organisms. The estimation is based on various models including Mode of action: by Russom et al. and Excess toxicity alerts: by von der Ohe et al (ext.), UFZ (unpublished), by Jäckel and Nendza as well as by Lipnick. None of the available models predicted structural alerts, so that we consider the substance not to be toxic to aquatic organisms.

Conclusion on classification

There is no indication for environmental toxicity of yttrium chromite, so that the substance is not classified for environmental toxicity.
