Pb uptake, translocation and allocation in <i>Iris pseudacorus</i> from arbuscular mycorrhizal fungi-assisted constructed wetlands

Popis výsledku v původním jazyce

Constructed wetlands (CWs) are commonly employed for the treatment of wastewater contaminated with heavy metals. Nevertheless, the efficacy of lead (Pb) removal in CWs is constrained by its toxic impact on wetland plants. This study investigated the effects of arbuscular mycorrhizal fungi (AMF) on Pb uptake, translocation, and allocation of Iris pseudacorus L. in CWs. Results showed that AMF inoculation of plants decreased Pb concentrations in the outlet water and increased Pb accumulation in the substrate by 27.8-35.2 % compared to non-inoculated controls. Pb allocation in I. pseudacorus was positively affected by AMF inoculation by ICP-OES, with Pb concentrations following the order: roots > rhizomes > leaves. Micro-proton-induced X-ray emission (mu-PIXE) analysis was employed to determine element localization, revealing that AMF enhanced nutrient absorption in plants and restricted the translocation of Pb from roots to leaves. AMF also improved the growth and photosynthetic performance of plants, with observed increases in the potential and actual photochemical efficiency of photosystem II by 0-8.1 % and 4.1-65.4 %, respectively. Furthermore, AMF enhanced the resilience of plants to Pb toxicity by improving nutrient uptake and strengthening antioxidative defenses. To our knowledge, this study is the first to employ mu-PIXE analysis to investigate the allocation and translocation of Pb within plant tissues influenced by AMF in CWs. The findings of this study may provide new insights for AMF-enhanced Pb removal in CWs.
