Evaluating mercury concentrations in edible plant and fungi species in the Canadian Arctic environment
Abstract Levels of environmental mercury (Hg) within the Canadian Arctic are a current area of concern. Although efforts have been made to reduce Hg released into the environment, levels remain elevated in flora and fauna. This study examined the concentrations of Hg in soil and naturally occurring...
