Presented by the Universidade do Estado do Rio de Janeiro, the study Cianobactérias como parametro de qualidade ambiental: um estudo do complexo lagunar de Jacarepaguá - Cyanobacteria as a parameter of environmental quality: a study of the Complexo Lagunar de Jacarepaguá (The Jacarepaguá Lagoon Complex), by Glaucia Freitas Sampaio, examines The Jacarepaguá Lagoon Complex, located in the state of the Rio of Janeiro, in Southeast of Brazil, is formed by the lagoons of Jacarepaguá, Camorim, Tijuca and Marapendi. These lagoons are interconnected to the sea by the Joatinga canal and receive contribution from tributary rivers and channels that come from Tijuca and Pedra Branca massifs. They receive industrial and domestic effluents, including diffuse contributions of the drainage basin, as well as water circulation from several origins, with a high pollution load. The cultural eutrophication associated with coastal ecosystems evolution processes, have produced a state of degradation of these waters with frequent waterblooms of potentially toxic cyanobacteria.
