Isotopic Composition of Nitrate as a Determination of Sources of Pollution
ثبت نشده
چکیده
A range of isotopic methods (using radioactive and stable isotopes) have been used to investigate groundwater processes and to determine the sources and pathways for groundwater contamination. Methods using stable isotopes of nitrogen have been applied in a variety of Australian and international groundwater studies. Isotopic methods have involved either application of tracer isotopes or studying natural variations in isotopic compositions. A variety of comprehensive texts outline applications of environmental isotopic methods in groundwater studies (Clark and Fritz 1997, Kendall and McDonnell 1998, Cook and Herczeg 2000, Hoefs 2004, Mook 2004).

Identification of the nitrate contamination sources of the Brusselian sands groundwater body (Belgium) using a dual-isotope approach.
Isotopic fingerprinting is an advanced technique allowing the classification of the nitrate source pollution of groundwater, but needs further development and validation. In this study, we performed measurements of natural stable isotopic composition of nitrate ((15)N and (18)O) in the groundwater body of the Brussels sands (Belgium) and studied the spatial and temporal dynamics of the isotope ...
متن کاملUsing nitrate dual isotopic composition (dN and dO) as a tool for exploring sources and cycling of nitrate in an estuarine system: Elkhorn Slough, California
[1] Nitrate (NO3 ) concentrations and dual isotopic composition (dN and dO) were measured during various seasons and tidal conditions in Elkhorn Slough to evaluate mixing of sources of NO3 within this California estuary. We found the isotopic composition of NO3 was influenced most heavily by mixing of two primary sources with unique isotopic signatures, a marine (Monterey Bay) and terrestrial a...
متن کاملNitrate Pollution and Preliminary Source Identification of Surface Water in a Semi-Arid River Basin, Using Isotopic and Hydrochemical Approaches
Nitrate contamination in rivers has raised widespread concern in the world, particularly in arid/semi-arid river basins lacking qualified water. Understanding the nitrate pollution levels and sources is critical to control the nitrogen input and promote a more sustainable water management in those basins. Water samples were collected from a typical semi-arid river basin, the Weihe River watersh...
متن کاملNatural denitrification in the Kakamigahara groundwater basin, Gifu prefecture, central Japan.
Although nitrate is recognized as the most common groundwater contaminant due to growing anthropogenic sources, such as agriculture in particular, its adverse effects on human and animal health are debatable. The current issue, however, is to control and reduce nitrate contamination with regards to the long residence time of groundwater within aquifers. Denitrification has recently been recogni...
متن کاملThe use of δ15N and δ18O tracers with an understanding of groundwater flow dynamics for evaluating the origins and attenuation mechanisms of nitrate pollution.
During early 2000, a new analytical procedure for nitrate isotopic measurement, termed the "denitrifier method", was established. With the development of the nitrate isotope tracer method, much research has been reported detailing sources of groundwater nitrate and denitrification mechanisms. However, a shortcoming of these tracer studies has been indicated owing to some overlapping of isotope ...
