Nitrate-Induced Photolysis in Natural Waters: Controls on Concentrations of Hydroxyl Radical Photo-Intermediates by Natural Scavenging Agents

Brezonik, Patrick L., Fulkerson-Brekken, Jennifer·1998·Environmental Science & Technology

Abstract

The importance of the principal natural scavenging agents for hydroxyl radicals ( • OH) was evaluated, and a general framework was developed to predict the significance of nitrate-induced, • OH-mediated degradation of aquatic contaminants. Rate constants for • OH scavenging by dissolved organic matter (DOM) from five surface water sources were in a narrow range (2.3 ± 0.77 × 10 4 (mg of C/L) - 1 s - 1 ), which is similar to previously reported values and suggests that the importance of DOM as a • OH sink can be estimated simply from the dissolved organic carbon (DOC) concentration of a water. Scavenging of • OH by carbonate and bicarbonate is generally less important, but these ions can be the major cause of • OH scavenging in low DOC, high alkalinity waters. Use of the framework is illustrated by predicting levels of • OH and half-lives of the corn herbicide acetochlor in waters ranging from pristine to highly influenced by agricultural activities.

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.
