From the database of chronic nickel toxicity to freshwater invertebrates, many individual EC10 or NOEC values for different individual species were selected. Chronic data on invertebrates belonging to different taxonomic groups being cladoceran (79% of the data points), amphipods (0.9% of the data), insects (7% of the data), hydrozoans (0.9% of the data), rotifers (5% of the data) and a mollusc (7% of the data). The NOEC/L(E) C10 varied between 1.4 μg/L for Lymnaea stagnalis (Schlekat et al., 2010) and 1,379µg/L for Brachionus calyciflorus (Schlekat et al., 2010). It is noted that the invertebrate data are heavily dominated by data on cladocerans.
The following table indicates those NOEC or EC10 values of high quality that have been carried forward for the HC5-& PNEC derivation:

From the database of chronic nickel toxicity to marine invertebrates, many NOEC/EC10/LOEC values are reported. EC10 values range from 22.5 μg Ni/L for reproduction of the polychaete, Neanthes arenaceodentata (DeForest and Schlekat, 2013), to 431 μg Ni/L for development of the bivalve,Crassostrea gigas (DeForest and Schlekat, 2013). The table below represents the NOEC, LOEC, or EC10 values of high quality carried forward for derivation of HC5 and aquatic marine PNEC:
