Environmental photochemistry of dienogest: phototransformation to estrogenic products and increased environmental persistence via reversible photohydration
Reversible photohydration of dienogest also yields estrogenic byproducts.
The effect of probe choice and solution conditions on the apparent photoreactivity of dissolved organic matter
Probe choice, pH, and [DOC] impact the apparent photochemical production of triplet dissolved organic matter in diverse natural waters.
A field analysis of lampricide photodegradation in Great Lakes tributaries
Field measurements, laboratory experiments, and kinetic modeling demonstrate that photodegradation of lampricides is limited in Great Lake tributaries.
Photobleaching of chromophoric dissolved organic matter (CDOM) in the Yangtze River estuary: kinetics and effects of temperature, pH, and salinity
CDOM photobleaching in the Yangtze estuary is affected by its source, and water temperature and pH but not salinity.
QSARs for phenols and phenolates: oxidation potential as a predictor of reaction rate constants with photochemically produced oxidants
One electron oxidation potential predicts the reactivity of phenol and phenolate compounds in a single correlation.

Atmospheric oxidation of halogenated aromatics: comparative analysis of reaction mechanisms and reaction kinetics
This study provides valuable insight into the mechanism of tropospheric degradation and fate of halogenated aromatic systems.
Concentrations of a triplet excited state are enhanced in illuminated ice
The concentration of a triplet excited state is nearly 100 times higher in illuminated ice compared to in solution, suggesting these oxidants can be important sinks for certain organic species in environmental snow and ice.
Effects of pH and dissolved oxygen on the photodegradation of 17α-ethynylestradiol in dissolved humic acid solution
This study explored the mechanisms responsible for pH and dissolved oxygen (DO) affecting the photodegradation of EE2 in dissolved humic acid (HA) solution.
About this collection
Collated by ESPI Editor-in-Chief Kris McNeill (ETH Zurich) we are pleased to present this handpicked selection of original research articles on the topic of Aquatic Photochemistry. Professor McNeill introduces the collection:
“In 2014, I had the pleasure to act as a guest editor for an Environmental Science: Processes & Impacts themed issue on Aquatic Photochemistry. The experience of editing that issue was really positive, not the least of which because we were fortunate to receive an extremely strong selection of papers on a wide range of photochemistry topics. In the time since that issue, ESPI has continued to be a home for high quality photochemistry studies among other topics. For my selection of papers to highlight, I thought I would take the opportunity to point out some of the photochemistry-related papers that I have enjoyed reading in ESPI over the past few years. I hope you enjoy them as much as I do.”
