Short-term toxicity to aquatic invertebrates
Administrative data
Link to relevant study record(s)
- Endpoint:
- short-term toxicity to aquatic invertebrates
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is highly insoluble in water, hence indicating that aquatic toxicity is unlikely to occur
- Justification for type of information:
- no experimental study is required for this substance based on the outcome of a full TDp assay (cfr. IUCLID Section 4 'Water solubility') and the identified acute and chronic threshold values for ecotoxicity.

Description of key information
No experimental study is required for palladium based on the outcome of a full TDp assay (cfr. IUCLID Section 4 'Water solubility') and the identified acute and chronic threshold values with other water soluble palladium substances.
The 48-hour EC50 for dihydrogen tetrachloropalladate was determined at 21.4 μg Pd L-1. This is the lowest threshold identified for this endpoint with soluble Pd substances (cfr Environmental Read Across Justification document in IUCLID Section 13 for more details).

Additional information
No experimental study is required for palladium based on the outcome of a full TDp assay (cfr. IUCLID Section 4 'Water solubility') and the identified acute and chronic threshold values with other water soluble palladium substances.
Three reliable studies were identified for this endpoint. The 48-hour EC50 for dihydrogen tetrachloropalladate was determined at 21.4 μg Pd L-1. This is the lowest threshold identified for this endpoint with soluble Pd substances (cfr Environmental Read Across Justification document in IUCLID Section 13 for more details).
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).
