Denitrification is an important component of the nitrogen cycle in soil, returning reactive
nitrogen to the atmosphere. Denitrification activity is often concentrated spatially in anoxic …

The Earth is experiencing excessive nitrogen (N) input to its various ecosystems due to
human activities. How to effectively and efficiently remove N from ecosystems has been, is …

Microplastics (MPs) broadly coexist with heavy metals (HMs) in soil, Cd and Cu are the main
types of soil HMs contamination, in addition to polystyrene (PS), which is also widely present …

Wildfire is a major driver of nitrogen (N) cycling and export from terrestrial to aquatic
systems. While fire is a natural process in many watersheds, it can still degrade water quality …

Wetland soil oxygen (O2) is rarely measured, which limits our understanding of a key
regulator of nitrogen loss through denitrification. We asked:(1) How does soil [O2] vary in …

This review evaluates research in the past 20 years focusing on groundwater nitrate removal
in the riparian zones of agricultural watersheds. Studies have reported a large range in the …

Riparian wetlands play a critical role in retaining nitrogen (N) from upland runoff and
improving river water quality, mainly through biological processes such as soil …

Denitrification, a significant pathway of reactive N-loss from terrestrial soils, impacts on
agricultural production and the environment. Net production and emission of the …

Assessing nitrogen dynamics in the estuarine landscape is challenging given the unique
effects of individual habitats on nitrogen dynamics. We measured net N 2 fluxes, sediment …

As aquatic-terrestrial ecotones, riparian zones are hotspots not only for denitrification but
also for nitrous oxide (N 2 O) emission. Due to the potential role of nosZ II in N 2 O …
