Copper uptake, essentiality, toxicity, detoxification and risk
Copper shows a hermetic effect (dual role) inside plants, positive at low/optimum levels, while toxic at high concentration due to its high redox properties (Fig. 3). Copper plays key roles in several plant physiological and biochemical reactions and therefore, it is considered an essential nutrient ( Nazir et al., 2019 ; Zhang and Li, 2019 ).
