Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC50 = 142 mg  Trinickel dicitrate/L
EC20 = 31 mg Trinickel dicitrate/L
NOEC = 7.4 mg Trinickel dicitrate/L

Key value for chemical safety assessment

Additional information

Data for toxicity to microorganisms were generated with the test item Trinickel dicitrate according to OECD 209 under GLP-conditions. These examination resulted in the effect values of EC50 = 142 mg/L (CI 156 -229 mg/L), EC20 = 31 (CI = 22 - 40 mg/L) and a NOEC of 7.4 mg/L.

Since it is stated in the EU RAR (2008), that an assessment of effects of nickel exposure on microbial activity in STPs will be completed under the same regulatory framework as the Sediment Effects Assessment, there was no derivation of a PNEC made from the single above mentioned data. A general PNECmicroorganism and local scale risk characterization for the EU will be completed on the part of the EU and afterwards reported post-SIAM.
