Mechanisms of sediment retention in estuaries
(Elsevier, 2009-10-21)
Phosphorus distribution pattern in sediments of natural and constructed wetlands
(Elsevier Science, 2017-11)
Two constructed wetlands for treating industrial and sewage effluents (CW1 and CW2) and two natural wetlands (NW1 and NW2), located in Argentina, were studied. The aims of the study were (1) to assess the accumulation and ...
Estudo da mobilização de metais e elementos traços em ambientes aquáticos do semi-árido brasileiro aplicando análises de componentes principais
(Sociedade Brasileira de Química, 2008)
The spatial and temporal retention of metals has been studied in water and sediments of the Gavião River, Anagé and Tremedal Reservoirs, located in the semi-arid region, Bahia - Brazil, in order to identify trends in the ...
The effect of pH on phosphorus sorbed from sediments in a river with a natural pH gradient
(Pergamon-Elsevier Science Ltd, 2019-08)
Phosphorus (P) is an essential nutrient for algal growth and its increase in water bodies produces eutrophication. On the other hand, sediments play an essential role in the processes of transformation and accumulation of ...
Factors that control the spatial and temporal distributions of phosphorus, nitrogen, and carbon in the sediments of a tropical reservoir
(2018-01-01)
The impacts of anthropic activities have had profound effects on the nitrogen (N) and phosphorus (P) cycles in many aquatic ecosystems. We investigated the spatial and temporal distributions of carbon (C), N, and P in the ...
SEAGRASS LOSSES CONCERNS: DOES SEDIMENT METAL POLLUTION MATTER?
(Sociedade Brasileira de Geoquímica, 2015)
Using an integrated approach to assess the sediment quality of an estuary from the semi-arid coast of Brazil
(2016-03-15)
The Jundiaí-Potengi Estuary (JPE) on the semi-arid coast of Brazil is influenced by multiple sources of pollution. Sediment quality at 10 JPE sites was evaluated through an integrated approach. Rainy and dry seasons were ...
Are sediments a risk? An ecotoxicological assessment of sediments from a quarry pond of the Upper Rhine River
(Springer Heidelberg, 2015-11)
Purpose: Contaminated sediments are an important exposure pathway for the aquatic fauna in the Rhine River. We applied bioassays with the aim to characterize the ecotoxicological hazard potential of sediments of an oxbow ...
The role of organic matter on the adsorption of mercury in sediments from Amazon lakes, Brazil
(Int Assoc Hydrological Sciences, 2006-01-01)
Gold has been exploited intensively in the Brazilian Amazon during the past 20 years, and the elemental mercury (Hg) used in amalgamating the gold has caused abnormal Hg concentrations in waterways. Since 1986 particular ...
