Nitrate pollution of ground and surface water bodies all over the world is generally linked
with continually increasing global fertilizer nitrogen (N) use. But after 1990, with more …

Nitrate pollution of surface water has attracted global attention, and the issue is becoming
increasingly significant in China. To identify the pollution status, sources, and potential non …

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

Nitrate pollution is of considerable global concern as a threat to human health and aquatic
ecosystems. Nowadays, δ 15 N/δ 18 O-NO 3− combined with a Bayesian-based SIAR model …

Coupled nitrogen and oxygen isotopes of nitrate have proven useful in identifying nitrate
sources and transformation in rivers. However, isotopic fractionation and low-resolution …

Water pollution in the form of nitrate nitrogen (NO 3−–N) contamination is a major concern in
most agricultural areas in the world. Concentrations and nitrogen and oxygen isotopic …

Abstract The nitrate (NO 3−) contamination of karst aquifers as an important drinking water
reservoir is increasing globally. Understanding the behavior of nitrogen (N) in karst aquifers …

Water resources are important in large basins which are important places for human
habitation and industrial and agricultural development. The background of editing this …

Traceability and quantification of agricultural non-point source pollution are of great
significance to water pollution management in watersheds. In this study, fluorescence …

Abstract Nitrate (NO 3−) contamination in groundwater is an environmental problem
worldwide. Partitioning the pollution into its sources is the key for effective controls. In this …
