New study published in ES&T Letters highlights the sensitivity of dissolved organic sulfur to photo-oxidation
Dissolved organic sulfur is an important component of waters, influencing the cycling of many elements. Our recent study published in the journal Environmental Science & Technology Letters documents how sunlight selectively photo-oxidizes reduced dissolved organic sulfur (DOS) to inorganic sulfate. The results have implications for the cycling of carbon, sulfur, and trace metals (e.g., mercury) in aquatic environments, and documents a reaction that may be relevant in the atmosphere.
