This work reviews applications of stable isotope analysis to the studies of transport and
transformation of N species in groundwater under agricultural areas. It summarizes evidence …

Karst aquifers, capable of storing and transmitting large amount of water, are the main
source of drinking water in many regions worldwide. Their excessive permeability leads to …

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 …

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 …

La agricultura tiene efectos directos e indirectos en las tasas y composiciones de la recarga
y de la biogeoquímica de las aguas subterráneas. Entre los primeros, cabe citar la …

Nitrate isotopic values are often used as a tool to understand sources of contamination in
order to effectively manage groundwater quality. However, recent literature describes that …

Riverine particulate organic matter (POM) samples were collected bi‐weekly to monthly from
40 sites in the Mississippi, Colorado, Rio Grande, and Columbia River Basins (USA) in 1996 …

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 …

Nitrogen (N) is one of the most important nutrients for plant growth. However, improper
management of N fertilization in agriculture has led to a large amount of nitrate leaching …

Groundwater nitrogen contamination is becoming increasingly serious worldwide, and
natural nitrogen attenuation processes such as anaerobic ammonium oxidation coupled to …
