dc.description.abstractIce-core records show that anthropogenic pollution has increased the global atmospheric concentrations of hydrogen peroxide and iodine since the mid-20th century. Here, for the first time, we demonstrate a highly efficient mechanism that synergistically produces them in icy water conditions. This reaction is aided by a key intermediate IO2H, formed by an I(-)ion with a dissolved O(2)in acidic icy water, which produces both I as well as O2H radicals. I recombines with I(-)to produce I(2)(-)at a diffusion-limited rate, followed by formation of I(3)(-)through disproportionation, while O2H yields H(2)O(2)with I(-)and a proton dissolved in icy water.en_US
