Geological-geomorphological and geochemical control on low arsenic concentration in the Lerma valley groundwater between the two high arsenic geologic provinces of Chaco-Pampean plain and Puna
(Science of the Total Environment, 2019-09)
Argentina is known for having one of the most extensive areas with high arsenic (As) concentration in groundwater in the world. These areas correspond to two main geological provinces, the Puna plateau and the Chaco-Pampean ...
Control of the mobilization of arsenic and other natural pollutants in groundwater by calcium carbonate concretions in the Pampean Aquifer, southeast of the Buenos Aires province, Argentina
(Elsevier, 2019-07)
The water supply for human consumption in the Chaco-Pampean region in Argentina is restricted by the low quality of groundwater due to elevated concentrations of arsenic and other trace elements. Previous studies indicated ...

(Universidade Federal de Minas GeraisUFMG, 2012-03-09)
Globalization of food trade, ease of international travel and increasing numbers of immunocompromised individuals are some of the factors attributed to the increase of food-borne parasitic infections. The methods described ...
Influência do sedimento no processo de remoção de nitrogênio por nitrificação/desnitrificação em lagoas de polimento
(Universidade Federal de Minas GeraisUFMG, 2016-02-12)
Polishing ponds are used as post-treatment units for effluents from UASB reactors. This technique is very efficient in removing organic matter, pathogens and, depending on operating conditions, can remove nitrogen. However, ...

Efeitos da recirculação de água de lavagem de filtros em um sistema de filtração direta em escala de bancada
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM ENGENHARIA SANITÁRIA, 2017-03-24)
The residues generated in the Water Treatment Plants (WTP) are mainly formed by the sedimentation and the filter backwash water (FBWW). The FBWW represents the largest portion of water loss, and may comprise up to 10% of ...
Linking hydrological, infinite slope stability and land-use change models through GIS for assessing the impact of deforestation on slope stability in high Andean watersheds
(2003-06-16)
In the Ecuadorian Andes, episodic slope movements comprising shallow rotational and translational slides and rapid flows of debris and soil material are common. Consequently, not only considerable financial costs are ...
