Resumo: | This review adresses the application of concentrations and ratios of nutrients (nitrogen and phosphorus) in the diagnosis of eutrophication in natural waters. We present a brief history of eutrophication and considerations on eutrophicating elements. The use of ratios in the diagnosis of eutrophication has limitations, since there are other parameters that prevent the proliferation of phytoplankton even under optimal nutrient conditions. Assays are used to identify the nutrient limitation to phytoplankton growth, while the trophic state index is used to assess the state of nutritional enrichment of an aquatic ecosystem. This work highlights the importance of the diagnostic study of eutrophication in natural waters subjected to the human impact, and suggests actions to improve their conditions, such as protection of riparian areas, terracing of agricultural areas, use of the required amount of fertilizer, and treatment of effluents from sewage to reduce the loads of N and P for lotic environments. |

Foi realizado um breve histórico sobre a eutrofização e considerações sobre os elementos eutrofizantes. O uso das razões no diagnóstico da eutrofização apresenta limitações, uma vez que existem outros parâmetros que impedem a proliferação do fitoplâncton mesmo em condições ótimas de nutrientes. Os bioensaios são utilizados para identificar a limitação de nutrientes ao crescimento fitoplanctônico, enquanto o índice de estado trófico é utilizado para avaliar o estado de enriquecimento nutricional de um ecossistema aquático. Este trabalho destaca a importância do estudo de diagnóstico da eutrofização nas águas naturais submetidas aos impactos decorrentes da ação humana e sugere ações para melhoria de suas condições, como a proteção de matas ciliares, terraceamento de áreas agrícolas, a utilização da quantidade necessária de fertilizantes e o tratamento dos efluentes oriundos dos esgotos para reduzir as cargas de N e P para os ambientes lóticos.Instituto Federal de Educação, Ciência e Tecnologia Fluminense2014-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/mswordhttps://editoraessentia.iff.edu.br/index.php/vertices/article/view/1809-2667.2014001310.5935/1809-2667.20140013Revista Vértices; Vol. 16 No. 1 (2014); 203-222Revista Vértices; Vol. 16 Núm. 1 (2014); 203-222Revista Vértices; v. 16 n. 1 (2014); 203-2221809-26671415-2843reponame:Vértices (Campos dos Goitacazes.
