Effects of a redox-active diketone on the photochemical transformation of roxarsone: Mechanisms and environmental implications.
Organoarsenical antibiotics pose a severe threat to the environment and human health. In aquatic environment, dissolved organic matter (DOM)-mediated photochemical transformation is one of the main processes in the fate of organoarsenics. Dicarbonyl is a typical redox-active moiety in DOM. However, the knowledge on the photoconversion of organoarsenics by DOM, especially the contributions of dicarbonyl moieties is still limited. Here, we systematically investigated the photochemical transformation of three organoarsenics with the simplest β-diketone, acetylacetone (AcAc), as a model dicarbonyl moiety of DOM. The presence of AcAc significantly enhanced the photochemical conversion of roxarsone (ROX), whereas only minor effects were observed for 3-amino-4-hydroxyphenylarsonic acid (HAPA) and arsanilic acid (ASA), because the latter two (with an amino (-NH Topics: Anti-Bacterial Agents; Arsanilic Acid; Arsenates; Carbon; Humans; Nitrogen Dioxide; Oxidation-Reduction; Pentanones; Peroxides; Photolysis; Roxarsone; Singlet Oxygen; Water Pollutants, Chemical | 2022 |
