Heavy metals in food crops: Health risks, fate, …

1/4/2019· Metal stress tolerance mechanisms and metal fate in crop plants The toxicity of heavy metals in crop plants is minimized by the plants'' ability to avoid (e.g., exocytosis) or tolerate stress. Avoidance is a basic strategy used to prevent heavy metals in the roots from entering the shoots and leaves by neutralizing their toxic effects in root cells ( Krzeslowska et al., 2010 ).
