We proposed to use artificial channels in laboratory assays to expose periphyton to substances released in rural environments in order to test the following hypotheses 1) a high concentration of humic substances decreases ...

Eutrophication is a process in which a water body is enriched in soluble nutrients stimulating the aquatic growth resulting in the depletion of dissolved oxygen. This phenomenon causes aquatic environment degradation as ...

Eutrophication causes aquatic environment degradation as well as serious problems for different purposes of water uses. Phosphorus and nitrogen, mainly as phosphate and nitrate respectively, are considered responsible for ...

Eutrophication is one of the environmental problems arising from the increase of essential nutrient concentrations, mainly phosphorus and nitrogen. In contrast to excess phosphorus, the depletion of phosphate rock deposits ...

One of the worst socio-environmental disasters to mark the history of Brazil and the world occurred in November 2015 and involved the mining sector. The collapse of the Fundao dam released approximately 43 million m(3) of ...

Eutrophication is characterized by excessive plant and algal growth due to the increased of organic matter, carbon dioxide and nutrients in water body. Although eutrophication naturally occurs over centuries as lakes age, ...

The aim of this study was to analyze temporal ..d vertical variation of the biomass and of phytoplankton primary productivity in an urban eutrophic reservoir, in relation to the physical and chemical characteristics of the ...
