Abstract:
... The ubiquity of sulfonamide antibiotics (SAs) in natural waters urges insights into their fate for ecological risk assessment in the aqueous euphotic zone. In this study, we investigated the effect of dissolved organic matter (DOM) on the photolysis of SAs with sulfapyridine as a reprentative. Results show that excited triplet state DOM (3DOM∗) is largely responsible for the photodegradation of su ...

aquatic environment; dissolved organic matter; environmental fate; freshwater; humans; metabolites; photolysis; pollutants; risk; seawater; sunscreens; surface water
Abstract:
... The occurrence of sunscreen agents and their metabolites in surface waters gives rise to public concerns. However, little is known about the environmental fate of these pollutants at present, especially for their metabolites. In this study, we investigated the photochemical of sunscreen agents and their metabolites in natural waters, adopting benzophenone-3 (BP-3) and its human metabolite 4-hydrox ...
