to higher plants
From the database of chronic nickel toxicity
to higher plants, there are many individual high quality NOEC/L(E)C10values
from different species. When
expressed as total soil Ni, these range from 11 mg/kg for Lycopersicon
esculentum(Rotahmsted Research, 2005) to 1303.2 mg Ni/kg for Zea
mays (Nie et al, 2015). Below
are the accepted high quality studies for terrestrial plants used for
derivation of the HC5and terrestrial PNEC.
