Toxicity to aquatic plants other than algae

 

Freshwater:

From the database of chronic nickel toxicity to freshwater plants, individual NOEC/L(E)C10 values reported for higher plant species. NOEC/L(E)C10 values range from 6.11 to 75 μg/L for Lemna minor (Gopalapillai et al., 2013; Schlekat et al., 2010); from 50 to 80 μg/L for Lemna gibba (Klaine and Knuteson, 2003); and from 184-196 μg/L for Spirodela polyrhiza (L.) Schleiden (Oláh et al., 2015) for a final range of 6.11 to 196 μg/L for the higher plants Lemna gibba, Lemna minor, and Spirodela polyrhiza.

The following table indicates those NOEC or EC10 values of high quality that have been carried forward for the HC5 & PNEC derivation
