Nitrogen is a requisite and highly demanded element for living organisms on Earth.
However, increasing human activities have greatly altered the global nitrogen cycle …

Constructed wetlands (CWs) are natural-like systems for wastewater treatment capable to
remove both pollutants and nutrients without additional energy demand. In these systems …

Denitrification, anaerobic ammonium oxidation (anammox), and dissimilatory nitrate
reduction to ammonium (DNRA) are three competing processes of microbial nitrate …

Chlorinated ethenes (CEs) are legacy contaminants whose chemical footprint is expected to
persist in aquifers around the world for many decades to come. These organohalides have …

Globally, shallow lakes have suffered from excessive nitrogen (N) loading due to increased
human activities in catchments, resulting in water quality degradation and aquatic …

Quantifying net N2 flux, the balance between nitrogen (N) fixation and denitrification, may
help inform the decades-long debate about the significance of N relative to phosphorus (P) …

Iron-based ecological floating beds (EFBs) are often used to treat the secondary effluent
from wastewater treatment plant to enhance the denitrification process. However, the impact …

Effects of nitrogen (N) deposition on microbially-driven processes in oligotrophic freshwater
ecosystems are poorly understood. We quantified guilds in the main N-transformation …

In permeable soils, excess nitrate from agriculture is transported vertically and accumulates
in aquifers. However, it can come back to the surface via groundwater movement and pollute …

Rivers and their hyporheic zones play an important role in nutrient cycling. The fate of
dissolved inorganic nitrogen is governed by reactions that occur in the water column and …
