Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data

biological effects monitoring
Type of information:
read-across based on grouping of substances (category approach)
Adequacy of study:
disregarded due to major methodological deficiencies
3 (not reliable)
Rationale for reliability incl. deficiencies:
significant methodological deficiencies
Though K3/K4 studies were evaluated and scored for reliability, robust summaries and unique IUCLID endpoint study records were not developed for such. Rather, a summary table of K3 and K4 studies evaluated and scored for this endpoint is provided in the field, "Any other information on results and tables" for informational purposes.
Justification for type of information:
See overall category approach justification: "Ni Ion" read-across

Specific details on test material used for the study:
This study record summarizes several different studies that utilize different test materials, so there is more than one test material to consider.

Data SourceStudy Design and FindingsReliability
Severne, B. C., & Brooks, R. R. (1972). A nickel-accumulating plant from Western Australia. Planta, 103(1), 91-94. K3: Does not meet important study design criteria. Certain plant species are known to be nickel-accumulators. Hybanthus floribundus from Western Australia found to have a plant:soil ratio of163.  Again, nickel species in soil not given.
