- Environmental scientists note the finding could revise pollutant degradation models in eutrophic lakes (per source)
Researchers at BESSY II have uncovered a previously unknown pathway for hydroxyl radical formation when water is exposed to UV light, challenging existing models of aqueous photochemistry. Using a novel ultrafast spectroscopy method, they showed that UV‑driven reactions can generate reactive radicals far more readily than thought, with implications for environmental and health risk assessments.
