[Display omitted] ► SO2 exhibited different, even contrary, effects on Hg0 oxidation in different conditions. ► With O2, few SO2 promoted Hg0 oxidation, while excess SO2 inhibited Hg0 oxidation. ► There is a balance SO2 concentration, where no obvious effect of SO2 can be observed. ► NO catalyzed SO...
