Global mercury cycle analysis published in ACP

We show that atmospheric oxidation of elemental mercury solely by atomic bromine can explain observed global patterns of mercury abundance, gradients, seasonal cycle, and deposition. The model using this oxidation mechanism predicts greater mercury deposition to the high-latitude oceans, where many productive fisheries are located.

Mean seasonal cycle of total gaseous mercury (TGM) at 15 sites in the northern hemisphere mid-latitudes and 3 sites in the Arctic. See paper for details.
