Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Key value for chemical safety assessment
Additional information
No data for short-term toxicity to aquatic invertebrates are available for the test substance Nickel aluminate. However, there are reliable data available for different structurally analogue test substances.
The environmental fate pathways and ecotoxicity effects assessments for Ni metal and Ni compounds is based on the observation that adverse effects to aquatic, soil- and sediment-dwelling organisms are a consequence of exposure to the bioavailable Ni-ion, released by the parent compound. The result of this assumption is that the ecotoxicology will be similar for all soluble Ni substances used in the ecotoxicity experiments. Therefore, data from soluble nickel substances are used in the derivation of ecotoxicological and environmental fate endpoints, based on the Ni-ion.
Freshwater:
From the database of acute toxicity to freshwater invertebrates, there are 30 high quality studies which predominantly report the 48h LC50 as the endpoint. Twenty-four species are represented in these studies, dominated by Daphnia magna and Ceriodaphnia dubia. The 48h LC50s values range from 0.013 mg Ni/L (Ceriodaphnia dubia; Schubauer-Berigan et al., 1993) to 4970 mg Ni/L (Daphnia magna; Chapman et al., 1980).
Marine:
From the database of acute toxicity to marine invertebrates, there are 16 high quality studies which report predominantly 48h LC50 and 48h EC50 as the endpoint. Twenty species are represented in these studies. The 48h LC50 values range from 0.23 mg Ni/L (Haliotis rufescens; Hunt et al., 2002) to 415 mg Ni/L (Penaeus duorarum; Bentley et al., 1975).
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.
