Description
Garrett McKay and seven colleagues separate natural organic matter from the Suwannee River into fractions and compare their light-related behaviour. Dissolved organic matter shapes how sunlight drives chemistry in rivers, and separating it by charge-to-size ratio offers a different lens than the usual size-based methods.
The least mobile fraction proved lightest, least aromatic, and yet the most efficient at producing fluorescence and reactive oxygen species under light. The most mobile fractions were dominated by a tannin-derived phenol rather than lignin, contrary to common expectations. The authors argue that charge and structure, not just aromatic content, drive how this material interacts with sunlight.
