This study evaluated the ability of the plant species Sainfoin (Onobrychis vicifolia) to absorb and tolerate heavy metals lead and copper. A greenhouse experiment was conducted with different levels of lead and copper contaminated soil. The results showed that Sainfoin was able to absorb significant amounts of both lead and copper into its roots and aerial parts, with greater absorption of copper. Higher metal concentrations in the soil led to increased antioxidant enzyme activity and biomarkers of oxidative stress in the plant. Specifically, the highest metal levels caused the greatest increases in enzymes like superoxide dismutase, catalase and glutathione peroxidase, as well as biomarkers like malondialdehyde, dityrosine and 8-hydroxy-2-de
