Inorganic iodine and bromine speciation in Arctic snow at picogram-per-grams levels by IC-ICP-MS
Iodine and bromine play central roles in polar atmospheric chemistry: iodine influences the atmospheric oxidative capacity and can generate cloud condensation nuclei, while bromine participates in ozone depletion reactions, known as bromine explosions. Here we present a very sensitive analytical met...
