The mechanisms which controls the fixation and/or release of P in sediment of an extremely acidic lake (pH = 2.0 to 3.0) and its response to the influence of eutrophic urban waste water were investigated. The results, in ...

Aquatic pollution by persistent organic compounds (POCs) in the southern hemisphere continues to be an important issue. Currently, no historic records of pollution are available to evaluate the inputs of chlorinated compounds ...

The mining activity in Peru is of long standing and its existence begins with the times and cultures pre Incas, Inca, colonial and the own Republic. This is due to the existence of deposits and important mineral resources ...

A 172 cm-long sediment core was collected from a small pristine lake situated within a centripetal drainage basin in a tropical karst environment (Ribeira River valley, southeastern Brazil) in order to investigate the ...

Historical records of trace elements in lake sediments provide source-to-sink information about potentially toxic pollutants across space and time. We investigated two lakes located at different elevations in the Ecuadorian ...

In this paper, evidence of paleoearthquake-induced soft-sediment deformation structures associated with the Magallanes–Fagnano Fault System in the Isla Grande de Tierra del Fuego, southern Argentina, has been identified. ...

The lake Igapó 1 in Londrina has been receiving in the past years sediment and pollutants load from the urbanization on Ribeirão Cambé watershed. This fact can cause the silting of the lake over time and the deterioration ...
