Stable Isotope Approach in Environmental studies: A Review

Stable isotope analysis has become known as important approach in ecological science but also in Geology, Biology, Climate, Organic chemistry, Botany and Zoology. The main purposes of this paper are to give a simple description of stable isotope concept, applications, and measurement method also for the animal food habits determination. The stable isotopes of Nitrogen (δ۱۵N) and Carbon (δ۱۳C) enable powerful tools for evaluating the origins of Nitrogen pollution in water systems and, associated to Bayesian Mixing Models, are the elective method to assess the trophic positions of the different taxa in a food
