High nitrite concentrations may occur mainly in recirculating aquaculture systems, but can
also be found under certain conditions in natural waters. Among studied freshwater …

Electrocatalytic reduction of nitrite (NO2−) is considered an effective method to solve its
environmental pollution issue as well as sustainable ammonia (NH3) synthesis under …

Data scarcity caused by extreme conditions during storms adds difficulties in performing
pollution source apportionment. This study integrated nonnegative matrix factorization with …

Maintaining low nitrite concentrations in aquatic systems is a major issue for stakeholders
due to nitrite's high toxicity for living species. This study reports on a cost-effective and …

Nitrogen (N) loading from anthropogenic activities is contributing to the eutrophication and
degradation of wetlands worldwide. Doñana (southwestern Spain), includes a dynamic …

The objectives of this study were to investigate water, ammonium nitrogen (NH 4+-N), and
nitrate nitrogen (NO 3−-N) export processes during the thawing period in a watershed with …

Advances in environmental sensors have resulted in new approaches for sampling streams
and rivers from moving platforms including drifters, drones, and boats. Despite the range of …

AIM: The aim of this study is to evaluate the spatial-temporal changes of chemical elements
in the surface waters of the Cachoeira River in order to evaluate the impacts of …

This research focuses on developing a mathematical model to simulate the spatial and
temporal variations of nitrite concentration in a natural river. A conceptual hybrid cell in …

Este estudo teve como objetivo avaliar, por meio de duas metodologias distintas, o estado
trófico do rio Catolé Grande sob diferentes níveis de vazão em uma seção transversal …
