Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Klimisch 1 studies are available for acute toxicity to Daphnia magna, acute toxicity to fish (Danio rerio) and algal growth inhibition (Pseudokirchneriella subcapitata) for this substance. All studies report results based on both test item concentrations and measured concentrations of ruthenium. The most sensitive trophic level based on acute data is algae and this result is used in order to determine the environmental classification of the substance. The only available chronic data are an EC10 and NOEC from the same algal study.

For PNEC derivation, data on the substance itself is used but PNEC values are reported based on concentrations of ruthenium. Environmental monitoring of ruthenium does not differentiate between different ruthenium substances therefore reporting PNEC values based on ruthenium concentrations allows the PNEC to be directly compared with predicted environmental concentrations.

Conclusion on classification

The most sensitive acute result for this substance is an algal EC50 of 0.380 mg test item L-1 (growth rate). As this result is <1 mg L-1, an acute environmental classification of Acute category 1 is assigned.

The only available chronic data are an algal NOEC and algal EC10 (0.023 and 0.019 mg test item L-1, respectively). As chronic data are available for only one trophic level, the chronic classification is assessed based on both the acute and chronic data, with the most stringent classification applied. Based on both the acute and chronic data a chronic environmental classification of Chronic category 1 is assigned. Acute and chronic M factors of 1 are also assigned.
