Summary: Estuaries are transitional ecosystems characterized by high biological productivity, vital for the adjacent coastal areas. They are under intense human exploitation, mainly urban and industrial, through the dumping of untreated effluents with know impacts on the ecosystem. Considering the wide quantity of sewage released in these ecosystems and the necessity to monitor the effects of these impacts, it is becoming increasingly important to use methods to identify the presence of pollutants and their effects on the estuarine food chain. In this sense, the project aims to evaluate the organic enrichment impact on the bethic food web in the estuary of the bay of Vitória, Espírito Santo, by using the data of stable isotopes (δ13C and δ15N). Thus, it is expected to identify spatially the presence of anthropogenic organic enrichment sources in this estuary and asses how theses indicators can be used to detect environmental impacts through the estuarine benthos.
