From Micronutrients to Potentially Toxic Elements: Physiological Responses of <i>Canavalia ensiformis</i> to Copper and Iron.

ABSTRACT: Background: The increase in potentially toxic elements (PTEs) in the soil is worrying, especially in agricultural soils due to the bioaccumulation factor. Copper (Cu) and iron (Fe) are micronutrients, responsible for important functions in the plant body, but the high availability of these elements in the soil can cause soil contamination and toxicity in plants; consequently, they can be considered PTEs. Objectives: The focus of this study is to understand the physiological responses (pigments, gas exchange, growth, biomass, accumulation) of Canavalia ensiformis to high levels of Cu and Fe in the soil, in isolation, and to identify which PTE is most harmful to its development. Methods: Two experiments (Cu and Fe) were conducted simultaneously in a greenhouse. Tr
