Article Synopsis
- Nitrous oxide emissions from river waters are crucial for understanding global NO levels, but the effect of sunlight on these emissions is not well understood.
- This study found that sunlight inhibits NO emissions in both ammonium and nitrate systems, with more significant reductions observed in the nitrate system as light increased.
- The results suggest that sunlight enhances the breakdown of organic matter, leading to higher NO reduction and lower production rates, indicating the need to include sunlight effects in models of NO processing in rivers.
Streams and rivers are important sources of nitrous oxide (N O), a powerful greenhouse gas. Estimating global riverine N O emissions is critical for the assessment of anthropogenic N O emission inventories. The indirect N O emission factor (EF ) model, one of the bottom-up approaches, adopts a fixed EF value to estimate riverine N O emissions based on IPCC methodology.

Although light exposure affects nitrogen transformations and nitrogen removal in some environments, such effects have rarely been explored and quantified in riverine overlying water. Herein, we examined the difference between dark and light conditions in the community composition and abundance of nitrogen transformation microbes in simulated overlying water by high-throughput sequencing and qPCR.
