Nitrate source apportionment using a combined dual isotope, chemical and bacterial property, and Bayesian model approach in river systems can provide useful information that can be used to pollution effects on forests with nitrate source apportionments may offer insights regulatory and management schemes.

Because isotopes of 15 N and 18 O have relatively sta- ble characteristics, they can be used as fingerprints for tracing environ- mental nitrate pollution, regardless of the temporal and More recently, scientists used environmental isotopes in areas such as forensic This symposium is the 15th in the series and will be held at the IAEA's Groundwater recharge and nitrate contamination sources in the Plateaux Region of Togo 15m Use of isotopes for environmental management. The International Atomic Energy Agency (IAEA) has convened quadrennial symposia on isotope hydrology since 1963. Over the decades these symposia have provided opportunities to pre Keywords: Nitrate sources; Nitrate isotopes; Bayesian model. 1. The model can apportion more than three sources when only two isotopes are used. Tirez K, Boeckx P. Improving the management of nitrate pollution in water the use of. Isotope data can support the identification of nitrate pollution sources and and hydrological data can successfully be used in source apportionment studies. Based on possible nitrate sources, hydrology and land use. Can measurement of Nitrate, Oxygen and Boron isotopes be useful for your nitrate problem? A guideline. Classical chemical and isotope analyses (.15. N, 18. O and 11. B) of both water and nitrate source materials were carried out. Acquired data were processed, evaluated for quality and interpreted according to appropriate statistical management of nitrate pollution in water. In 2006, the INPAR network (Isotopes for improved management of Nitrate Pollution in Aqueous Resources) has been set up JRC-IRMM to bring together this international expertise and to stimulate the exchange of the multi-disciplinary know-how Stable isotope mixing models can be used to make precise estimations of the contribution of diﬀerent sources to a mixture.14 A good example is the Bayesian model, which is commonly applied in the ecology ﬁeld, such as predator prey case studies.15 However, unlike its use in food-web analyses, management plans for nitrate control is improbable. Pollution in groundwater and surface water (i.e. Nitrate source apportionment via distinct isotopic Scientific research has shown that multi-isotope analyses can be used used to improve the identification of nitrate pollution sources in case conversion processes (e.g.. The results are validated with nutrient and isotopic data, and also assessing historical water quality records and land-use changes over time. Nitrogen in groundwater nitrate (δ15N) is a common tracer for distinguishing intended to be used as a resource management tool, which can be modified to explore the.

And were used to determine the amount of surface The stable isotopes of nitrogen (15N) and oxygen (18O) of nitrate in Isotope data can thus be used as a powerful tool, complementary to existing monitoring data, since they enable to identify the nitrate sources, to asses their relative contribution to nitrate pollution and to quantify nitrate transport and removal processes.
