Iron sulphides, mainly in the form of mackinawite (FeS), pyrrhotite (Fe 1-x S, x= 0–0.125) and
pyrite (FeS 2), are the most abundant sulphide minerals and can be oxidized under anoxic …

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 …

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 …

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 …

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

Antibiotics are an increasing focus of interest due to their high detection frequency in the
environment. However, their presence in water bodies is not regulated by environmental …

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

The nitrate anion is a simple, abundant and relatively stable species, yet plays a significant
role in global cycling of nitrogen, global climate change, and human health. Although it has …

Abstract Nitrate (NO 3-) pollution adversely impacts surface and groundwater quality. In
recent decades, many countries have implemented measures to control and reduce …
