Division/Committee: [ENVR: Division of Environmental Chemistry]

Aquatic photochemical transformations are important in geochemistry and environmental chemistry in diverse contexts, from natural systems where sunlight is acting on surface waters to engineered systems using UV irradiation. Light may act directly upon target compounds or indirectly through interactions with redox-active species including minerals, dissolved organic matter, and small molecule sensitizers. Understanding the roles of photochemistry in these complex systems provides insight into the fate of chemical and biological species in the environment. In this symposium, we invite submissions that explore the direct and indirect photochemical transformations of natural and anthropogenic compounds, as well as interactions of light with organic matter, biomolecules, redox-active minerals, and microorganisms. Topics that would be covered in this session include, but are not limited to: Photochemistry of dissolved organic matter Reactive oxygen species Photochemistry in water/wastewater treatment Ice photochemistry Plastic photochemistry Photochemistry in aqueous aerosols Photochemical transformation of pollutants Photochemistry of biomolecules Photochemical disinfection Photochemically driven element cycling Field studies
