An Overview of an Acidic Uranium Mine Pit Lake (Caldas, Brazil): Composition of the Zooplankton Community and Limnochemical Aspects
(Springer, 2015-09-01)
Water samples were collected quarterly for 1 year from the newly created Osamu Utsumi uranium mine pit lake, Brazil, which is affected by acid mine drainage (AMD). The water presented mean pH values of 3.8, high mean ...
The heavy metal contamination of Lake Junín National Reserve, Peru: An unintended consequence of the juxtaposition of hydroelectricity and mining
(Geological Society of America, 2014)
Hydraulic engineering is increasingly relied upon to provide the necessary dry-season discharge for Peru’s hydroelectricity generation. Redirecting stream flow can yield unintended consequences, however, and here we document ...

Dynamics of Phosphorus in sediments of a naturally acidic lake
(Elsevier, 2013-01)
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 ...
Iron buffer system in the water column and partitioning in the sediments of the naturally acidic Lake Caviahue, Neuquén, Argentina
(Elsevier Science, 2016-05)
Sedimentary iron partitioning was studied for five sediment strata (16 cm depth) at three sampling sites of the naturally-occurring acidic Lake Caviahue (Patagonia, Argentina). Additionally, water column iron was modeled ...
Optical properties and light penetration in a deep, naturally acidic, iron rich lake: Lago Caviahue (Patagonia, Argentina)
(Elsevier Gmbh, 2013-03)
The optical properties and light climate in the deep and extremely acid Lake Caviahue have been studied in order to better understand its characteristics and the possible influence upon the phytoplankton community. The ...
The crater lake of Copahue volcano (Argentina): Geochemical and thermal changes between 1995 and 2015
(Geological Society Publications House, 2016-12)
The crater lake and associated hydrothermal features of Copahue volcano have been studied intensively over the last 20 years (1995-2015). The geochemical and isotopic compositions of the waters provide insights into the ...
Utilisation of organic compounds by osmotrophic algae in an acidic lake of Patagonia (Argentina)
(Springer Tokyo, 2014-04)
We investigated whether algal osmotrophy in naturally acidic Lake Caviahue is an important process for acquisition of organic carbon and organic nitrogen. To accomplish this, we quantified algal assimilation of organic ...
Structural description of humic substances from subtropical coastal environments using elemental analysis, FT-IR and C-13-solid state NMR data
(Coastal Education & Research Foundation, 2005-03-01)
Elemental composition and spectroscopic properties (FT-IR and CP/MAS C-13-NMR) of sedimentary humic substances (HS) from aquatic subtropical environments (a lake, an estuary and two marine sites) are investigated. Humic ...
