Photochemical reactions contribute to the transformation of contaminants and
biogeochemically important substrates in environmental aquatic systems. Recent research …

Brown algal kelp species are the most efficient iodine accumulators among all living
systems, with an average content of 1.0% of dry weight in Laminaria digitata, representing a …

During springtime in the polar regions, unique photochemistry converts inert halide salt ions
(eg Br−) into reactive halogen species (eg Br atoms and BrO) that deplete ozone in the …

Halogens are very reactive chemicals that are known to play an important role in
anthropogenic stratospheric ozone depletion chemistry, first recognized by Molina and …

Bromine (Br) is widely distributed through the lithosphere and hydrosphere, and its
chemistry in the environment is affected by natural processes and anthropogenic activities …

This study demonstrates that the oxidation of bromide by birnessite (δ-MnO2) results in the
concurrent production of soluble manganese (Mn (II)) and reactive bromine (RBr) species in …

Reactions of dissolved organic matter (DOM) with photochemically generated reactive
halogen species (RHS) may represent an important natural source of organohalogens …

Metal oxides play a critical role in the abiotic transformation of iodine species in natural
environments. In this study, we investigated iodide oxidation by manganese dioxides (β …

Volatile organoiodine compounds (VOIs) are the main carrier of iodine from the oceans to
the atmosphere. We have identified a novel, sea‐surface source of the short‐lived VOIs …

Iodine species in the troposphere are linked to ozone depletion and new particle formation.
In this study, a full year of iodine monoxide (IO) columns retrieved from measurements of the …
