Native accumulator plants with a differential mercury phytoremediation potential in a region in Southern Amazon.

Mercury (Hg) is a non-essential trace metal, toxic to living beings and complex to quantify and mitigate in the environment. In this study, 25 plant species native to an Amazon-Cerrado transition area were tested for use in Hg remediation. Species identification, Hg quantification in plant biomass and soil at each sampling point, and evaluation of Hg compartmentalization in each plant were carried out.
