As the main anion of groundwater, the content of sulfate affects the drinking water safety and
ecological security directly. In recent years, with the acceleration of industrialization and …

Over the past decades, groundwater quality has deteriorated worldwide by nitrate pollution
due to the intensive use of fertilizers in agriculture, release of untreated urban sewage and …

The identification of nitrate (NO 3−) sources and biogeochemical transformations is critical
for understanding the different nitrogen (N) pathways, and thus, for controlling diffuse …

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

Abstract Nitrate (NO 3−) pollution of groundwater is a persistent and widespread problem
worldwide, particularly in intensive agricultural regions with high nitrogen (N) surplus …

Abstract Fluoride (F−) and nitrate (NO 3−) in groundwater have caused serious health
problems worldwide. However, in the Chinese Loess Plateau where groundwater is the …

Nitrate is usually the main pollution factor in the river water and groundwater environment
because it has the characteristics of stable properties, high solubility and easy migration. In …

Abstract In the European Union, nitrate vulnerable zone (NVZ) should be designed for the
mitigation of nitrate (NO 3−) contamination caused by agricultural practices. Before …

Abstract Groundwater nitrate (NO 3-) pollution has attracted widespread attention; however,
accurately evaluating the sources of NO 3-and their contribution patterns in regional …

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 …
