Atmospheric depletion of mercury over Antarctica during glacial periods
Mercury is a globally dispersed toxic metal that affects even remote polar areas. During seasonal atmospheric mercury depletion events in polar areas, mercury is removed from the atmosphere1,2 and subsequently deposited in the surface snows3. However, it is unknown whether these events, which have been documented for the past two decades, have occurred in the past. Here we show that over the pa...

متن کاملBromine atom initiates atmospheric oxidation of Hg(0) in mercury depletion events
Quantum chemical calculations have been carried out to investigate the thermochemistry of BrHg• forming bonds with atmospherically abundant radicals Y• (Y = NO2, HO2, ClO, BrO, or IO). The coupled cluster method with single and double excitations (CCSD), combining with relativistic effective core potentials, is used to determine the equilibrium geometries and harmonic vibrational frequencies of...
