Description of key information

NOEC and EC10 values are available for 18 different species. TheNOEC/EC10 values vary between 32 mg Zn/kgdw for Trifolium pratense andVicia sativa to 5855 mg Zn/kg dw for Triticum aestivum . 

Key value for chemical safety assessment

Additional information

For plants, 45 individual high quality NOECs/EC10 values are selected for PNEC derivation, representing 18 different species. NOEC and EC10 values vary between 32 mg Zn/kgdw for Trifolium pratense and Vicia sativa (Van der Hoeven and Henzen, 1994) to 5855 mg Zn/kg dw for Triticum aestivum (Warne et al., 2008a).

All toxicity data are expressed as added Zn concentration in soil, based on either the nominal dose added or on measured, background corrected soil Zn concentrations.
