Descripción
Lead (Pb) and zinc (Zn) pollution are major environmental concerns in salt marshes affected by anthropogenic inputs. This study aims to enhance our understanding of the impact of Pb and Zn increases, individually and in combination, on Limonium brasiliense and Atriplex vulgatissima by examining accumulation patterns and combining morphological, physiological, and biochemical biomarkers, summarized using the Integrated Biological Response index (IBRv2). Our findings showed leaf-shape plasticity in L. brasiliense, whereas in A. vulgatissima a canalized morphology across treatments, a trend reflected in most biomarkers. Both species survived and maintained biomass, indicating tolerance to metal-induced stress. In L. brasiliense, variations in water content, leaf size, pigment concentration, photosynthetic efficiency, and ascorbate peroxidase activity highlighted a significant role of Zn in disrupting physiological function. In A. vulgatissima, most biomarkers, except leaf size and the activities of superoxide dismutase and guaiacol peroxidase, remained unchanged after treatments. Under Pb + Zn treatment, L. brasiliense accumulated Pb in roots and Zn in shoots, with a reduction in absorption efficiency (AE), whereas A. vulgatissima showed root-restricted accumulation of both metals and an increased AE. The IBRv2 indicated greater stress under Pb + Zn treatment in L. brasiliense and under Zn treatment in A. vulgatissima. Thus, these results suggest that L. brasiliense is more suitable for Pb phytostabilization and Zn phytoextraction, while A. vulgatissima may contribute to phytostabilization of both metals, showing distinct strategies: plasticity and modulation versus inherent tolerance, respectively. The findings highlight species-specific differences in metal tolerance, accumulation, and stress responses, directly impacting phytoremediation and biomonitoring in metal-contaminated environments.
