Description of key information

High quality chronic NOEC/EC10 values are available for Lemna minor (growth).

Key value for chemical safety assessment

Additional information

11 reliable and relevant NOEC/EC10s are available for one higher plant species,Lemna minor. They range between 2.1 and 116 µg Cu/L. The geometric mean NOEC/EC10 is 16 µg Cu/L (ARCHE, 2022a).

The available data onLemna minor(Antunes et al., 2012) demonstrated that the algae model can be used for normalization of the Lemna NOEC values (ARCHE, 2022b).
