In this review,we summarized the in vitro andinvivo removal approaches of cadmium and antibiotics residues and the combined removal methods of cadmium and antibiotics in wetland plants.The roots of wetland plant is the main part for cadmium removing,the migration and transformation of cadmium in wetland plant rhizosphere microenvironment were affected by organic acids in rhizosphere secretions,soil physical and chemical properties,and microbial community.Chelation/complexation of chelates in plant played an important role in the removal of cadmium in plant body,and iron film on plant root surface was an important chelate in vitro to exert its removal efficiency.The synergistic effect of plant-microorganisms in wetlands could effectively remove antibiotic residues.However,antibiotic residues significantly affected the composition and structure of the rhizosphere microbial commu-nity,with the risk of producing antibiotic-resistant bacteria and antibiotic-resistant genes.Combined-pollution by cad-mium and antibiotics showed different complex behavior characteristics due to their various type and the concentra-tion of the pollutants show,leading to toxic effects on wetland plants.Complex pollutants exhibit the toxic properties of their parent pollutant and entail intricate mechanisms of toxicity.Recently,there are a few studies on the synergic removal of heavy metals and antibiotics using wetland plants.Given that,we proposed the deficiencies and future development directions of the current research on the removal of heavy metal and antibiotics by wetland plants,to provide theoretical support for wetland phytoremediation technology of heavy metal and antibiotic pollution.
