EC50 = 142 mg Trinickel dicitrate/LEC20 = 31 mg Trinickel dicitrate/LNOEC = 7.4 mg Trinickel dicitrate/L
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
