Industrialization has systematically contributed to increasing emissions of heavy metals and emerging contaminants, with the consequent deterioration of the environmental quality.The heavy metals and emerging contaminants concentrations in surface waters and sediments and their relationship with the accumulation and physiological changes in aquatic plants in areas with anthropogenic impact were evaluated. Different macrophytes revealed high capacity to accumulate those contaminants in their tissues, from contaminated water bodies. Thus, the manifestation of physiological changes demonstrated the importance in monitoring studies in aquatic environments with consequences of ecological risk [1].However, the high accumulation levels of contaminants in tissue observed in some plants and the physiological tolerance, which revealed the potentiality for use in remediation systems with contaminated water and sediment. The exposure in constructed wetlands, simulating an aquatic environment contaminated with wastewater discharges, allows the evaluation of levels of bioconcentration, translocation and removal efficiency in these systems [2].Keywords: Macrophytes, heavy metals, emerging contaminants, biomonitoring, treatments, constructed wetlandReferences[1]C.A.
