Results and discussion
Any other information on results incl. tables
All five nickel compounds (nickel chloride, nickel dinitrate, nickel hydroxycarbonate, nickel sulphate, nickel metal) release Ni2+ into the environment, and partitioning coefficients for this ionic form are therefore relevant for all five substances. Ni2+ partitioning coefficient for solid-water in suspended matter (Kp susp) is 26303 (log Kp susp = 4.42). Ni2+ partitioning coefficient for sediment-porewater (Kp sed) is 7,079 (log Kp sediment = 3.85). Ni2+ partitioning coefficient for soil-water (Kp soil) is 726 (log Kp soil = 2.86). Ni2+ partitioning coefficients were based on 50th percentiles of distributions of values from available high quality data.
Applicant's summary and conclusion
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.
