An overview of capillary electrophoresis in element speciation analysis of the environment
(Bentham Science Publishers, 2014-04)
This article focuses on the main developments in element speciation analysis by capillary electrophoresis (CE) since the 1990s. A brief description of the main techniques employed in CE analysis has been reviewed with ...
Mercury speciation in contaminated soils by thermal release analysis
(Kluwer Academic PublDordrechtHolanda, 1996)
On-line bi-directional electrostacking for As speciation/preconcentration using electrothermal atomic absorption spectrometry
(Elsevier Science BvAmsterdamHolanda, 2007)
Organic aerosols in a Brazilian agro-industrial area: Speciation and impact of biomass burning
(2016-03-01)
This work presents the first comprehensive organic characterization of atmospheric aerosols from an agro-industrial region (São Paulo State, Brazil) highly impacted by biomass burning. The organic speciation was performed ...
In situ arsenic speciation at the soil/water interface of saline-alkaline lakes of the Pantanal, Brazil: A DGT-based approach
(2022-01-15)
Arsenic (As) is a naturally occurring element in the Earth's crust, exhibiting toxicity towards a wide range of living organisms. Its properties and environmental dynamics are strongly regulated by its speciation, and the ...
Chromosomes and speciation in tuco-tuco (Ctenomys, Hystricognathi, Rodentia)Хромосомы и видообразование у туко-туко (Ctenomys, Hystricognathi, Rodentia)
(Institute of Cytology and Genetics of Siberian Branch of the Russian Academy of Sciences, 2016-09)
Tuco-tucos, South American rodents of the genus Ctenomys represent an interesting model of speciation. Their strict territorial and solitary life under the earth, vast but highly fragmented habitats, low migration activity ...
Preconcentration, speciation, and determination of key elements in biological samples in Latin America
(Springer Heidelberg, 2013-08)
The concentrations of trace elements in biological samples are far below those achieved directly by most atomic or plasma-based techniques and the detection power needs to be improved by the use of a preconcentration step. ...
