Macrophytes are fundamental photosynthetic organisms for functioning freshwater ecosystems, identified as potential bioindicators of mercury (Hg) in the environment. We quantified concentrations total Hg (THg) water and macrophytes (Paspalum repens Berg.) from 17 lakes on Araguaia River floodplain, aiming to compare bioconcentration factor (BCF) aerial tissues roots; evaluate translocation (TF) between plant tissues; assess influence environmental factors land use THg macrophytes. The BCF was significantly higher roots (1.29 ± 0.32) than (0.41 0.34), with low TF (0.14 0.06). highest were determined intensity a pH close neutral, indicating transport particulate-bound immobilization column. In contrast, wetlands priority areas macrophytes, associated sulfate, dissolved oxygen, oxidation–reduction water. Thus, although P. is not suitable bioindicator mobilization by anthropogenic our study area, results suggest sites that favorable methylation.
