[...] Gd highlight the The augmented total antioxidant capacity and lipid peroxidation values CAT show that the significant impacts of Gd on the oxidative stress response GST are enhanced under warming enhanced toxic LPO The increased superoxide dismutase and catalase values HSP demonstrate the combined impact of Gd, warming & effects of Gd in acidification.
