Gaseous elemental mercury in air decreased after phasing out of amalgam electrolysis

A new study by the team of the Environmental Geology and Geochemistry Department led by Tomáš Navrátil found that elevated concentrations of gaseous elemental mercury and also particle-bound mercury in the air near Spolana Neratovice decreased rapidly after the shutdown of the amalgam electrolysis line in 2017. Annual air measurements performed since 2013 indicated a decrease by over 60 %. The study published in journal Environmental Science Pollution and Research further indicates that the concentrations of gaseous elemental mercury in the air near Neratovice still remain approximately doubled compared to sites unaffected by emissions.
