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 …

Understanding where nitrate is mobilized from and under what conditions is required to
reduce nitrate loss and protect water quality. Low frequency sampling may inadequately …

Karst terrain seasonal monsoonal rainfall is often associated with high concentrations of
nitrate-N in streams draining agricultural land. Such high concentrations can pose problems …

Land use patterns and regional hydrogeological conditions have a great impact on nitrate
sources and transformation in groundwater at the large-basin scale. In this study …

Although numerous studies focused on nitrate source, transformation and transport of river
water in karst area have been reported, it's still unclear in understanding nitrate main source …

As a vital stormwater pollution source, the pollutants associated with road-deposited
sediment (RDS) have become a growing concern in urban water management. Green …

Nitrate is a highly concerned pollutant in global aquatic ecosystem, resulting in
eutrophication and water quality deterioration. As a result of the dissolved inorganic carbon …

Nitrate is a prominent pollutant in surface and groundwater bodies worldwide. Isotopes in
nitrate provide a powerful approach for tracing nitrate sources and transformations in waters …

Special hydrological structures coupled with rainfall and agricultural activities have great
impacts on water quality in karst areas. High-frequency hydro-chemical, dual nitrate isotopes …

As an important recharge source for lakes, groundwater has become one of the dominant
routes of nitrogen (N) input into lakes. Understanding the source and behaviour of N around …
