The III Workshop on Chemistry and Biochemistry RedOx took place on March 19–20, 2025, at the Faculty of Chemistry and Pharmacy, Pontificia Universidad Católica de Chile. Under the theme “Oxidants, Signaling, and Metabolic Control”, the event gathered leading experts in redox chemistry and biochemistry for two days of intensive discussion and groundbreaking research.
I had the honor of delivering the keynote address, titled “Atmospheric Pollution and Oxidative Potential: More Than Meets the Eye.” My presentation tackled the complex relationship between airborne particulate matter and its capacity to trigger oxidative stress—a subject that goes beyond simple mass concentration measurements. I delved into:
- The Anthropocene and Air Quality: How the human footprint has redefined environmental processes and why understanding oxidative potential is critical in our modern era.
- Innovative Measurement Techniques: An overview of advanced assays, including the DTT-based method, that reveal the chemical reactivity of pollutants.
- Health and Economic Impacts: A discussion on the far-reaching effects of air pollution, from public health burdens to economic consequences.
- Emerging Research Trends: Insights into how the interplay between chemical composition and biological response challenges traditional views of air quality assessment.
The workshop itself was a powerhouse of interdisciplinary exchange, featuring sessions on enzyme redox mechanisms, nanoparticle toxicity, and clinical applications in oxidative stress management. The discussions reinforced that tackling air pollution requires merging chemical insights with biological perspectives—an approach that is essential in addressing the challenges of the Anthropocene.
I extend my sincere thanks to the organizers, my colleagues, and all participants for making this workshop a resounding success. The event not only advanced our collective understanding of atmospheric pollution but also set the stage for future collaborations and innovative solutions in redox science.
