Halogen radicals contribute to photooxidation in coastal and estuarine waters
Open accessAbstract
Significance: Scavenging by halides to produce halogen radicals is recognized as a significant sink for hydroxyl radical ( • OH) in seawater. However, the contribution of halogen radicals to the transformation of marine organic constituents has not been explored. Here, we demonstrate that halogen radicals are formed predominantly by direct oxidation of seawater halides (i.e., Cl − , Br − ) by excited-state triplet dissolved organic matter chromophores, an • OH-independent pathway. The resulting halogen radicals increase photochemical transformation rates of important algal products, including dimethyl sulfide and the neurotoxin domoic acid, by up to fivefold relative to freshwater conditions. The contribution of halogen radicals to the photochemical transformation of critical marine organic compounds may have important implications for biogeochemical processes in coastal and estuarine waters.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
