The chemical composition of dissolved organic matter (DOM) exerts significant influence on aquatic energy dynamics, pollutant transportation, and carbon storage, thereby playing pivotal roles in the local water quality and regional-global biogeochemical cycling. However, the effects of natural climate change and local human activities on watershed characteristics and in-river processes have led to uncertainties regarding their contributions to DOM chemistry in coastal rivers, creating challenges for effective water management and the study of organic matter cycling. In this investigation, we employed a combination of stable isotopic analysis, optical techniques, and Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS) to elucidate the sources, optical properties, and molecular composition of DOM in three South China coastal rivers.

Article Synopsis
  • The research investigates sulfur cycling in nitrate reduction during hypoxic conditions in sulfate-rich environments, highlighting a gap in understanding this mechanism.
  • The study utilizes nitrogen and oxygen isotope analysis and metagenomic sequencing to reveal interactions between sulfate reduction and denitrification in the Aha reservoir.
  • Findings indicate that sulfides significantly influence denitrification, identifying specific bacterial genera that play crucial roles in both processes under these low-oxygen conditions.
