Nitrate (NO3−) contamination of surface-and groundwater is an environmental problem in
many regions of the world with intensive agriculture and high population densities …

Natural abundances of the rare stable isotope of nitrogen, 15 N, are now being used widely
in research on N cycling in organisms and ecosystems. 15 N natural abundances are used …

Increasing diffuse nitrate loading of surface waters and groundwater has emerged as a
major problem in many agricultural areas of the world, resulting in contamination of drinking …

We report a new method for measurement of the isotopic composition of nitrate (NO3-) at the
natural-abundance level in both seawater and freshwater. The method is based on the …

Contamination from agricultural sources and, in particular, nitrate pollution, is one of the
main concerns in groundwater management. However, this type of pollution entails the …

We report a novel method for measurement of the oxygen isotopic composition (18O/16O) of
nitrate (NO3-) from both seawater and freshwater. The denitrifier method, based on the …

Nitrate (NO3−) concentrations in public water supplies have risen above acceptable levels
in many areas of the world, largely as a result of overuse of fertilizers and contamination by …

Tracers in Hydrology and Water Research is a comprehensive overview of the application of
natural and artificial tracers in hydrology and environmental research. Taking a unique …

We present a novel method for nitrogen and oxygen natural isotopic abundance analysis of
nitrate and nitrite of seawater and freshwater at environmental concentrations. The method …

Nitrate concentration in most aquifers in arid and semi-arid areas has increased in the past
several decades as a result of human activities. Under the predominantly oxic conditions of …
