Resum
The negative effects of sewage discharge were analyzed in two Amazonian environments (the Caete Estuary and the Cereja River) subject to different levels of anthropogenic impact. For this, samples of surface water were collected for the analysis of physical, chemical, and microbiological parameters during dry and wet season. In the Caete Estuary, the results indicated high levels of total nitrogen and fecal coliforms in the upper sector. Eutrophic conditions were recorded in the wet and dry seas...
