Article Synopsis
  • - Nitrate (NO) is the primary form of nitrogen in rivers, and its rise can cause serious environmental problems like eutrophication and reduced biodiversity, making it crucial to track its sources and flow.
  • - Both isotope mixing and hydrological models are useful for identifying NO sources but have significant limitations; therefore, this research proposes a new combined protocol to address these challenges.
  • - When applied to the Qihe River, the combined approach revealed contributions of NO from chemical fertilizer, sewage, and soil organic nitrogen as 45.1%, 30.9%, and 23.9%, respectively, highlighting the effectiveness of integrating both models for better accuracy.

The high levels of nitrate (NO) in the surface water have contributed to eutrophication and other eco-environmental damages worldwide. Although the excessive NO concentrations in rivers were often attributed to anthropogenic activities, some undisturbed or slightly disturbed rivers also had high NO levels. This study utilized multi-pronged approaches (i.

Besides cascade hydropower development, regional socio-economic activities also significantly affect water quality in the drainage region. However, it remains challenging to ascertain the implications of the damming effects and regional sustainability on water quality. This study examined the variations in water quality indicators, including chemical oxygen demand (COD), ammonia nitrogen (NH-N), and total phosphorus (TP), during the cascade hydropower development (both the construction and impoundment periods from 2006 to 2023) in the lower reaches of the Jinsha River (the upper reaches of the Yangtze River).

A small molecule disulfide unit technology platform based on dynamic thiol exchange chemistry at the cell membrane has the potential for drug delivery. However, the alteration of the CSSC dihedral angle of the disulfide unit caused by diverse substituents directly affects the effectiveness of this technology platform as well as its own chemical stability. The highly stable open-loop relaxed type disulfide unit plays a limited role in drug delivery due to its low dihedral angle.
