Analytical approaches for arsenic determination in air : a critical review
Sánchez-Rodas Navarro, Daniel Alejandro
; Sánchez de la Campa Verdona, Ana María; Alsioufi, Louay (Elsevier Masson, 2015)
This review describes the different steps involved in the determination of arsenic in air, considering the particulate matter (PM) and the gaseous phase. The review focuses on sampling, sample preparation and instrumental ... -
Arsenic and antimony speciation in atmospheric particulate matter of Andalusia
(Universidad de Huelva, 2017)A new method for Sb extraction in PM samples has been developed, based on the use of microwave radiation (operated at 90 W during 3-6 min) with a 0,05 mol L1 NEhOH-HCl solution. The analysis of the extracts was performed ... -
As3MT and GST Polymorphisms Influencing Arsenic Metabolism in Human Exposure to Drinking Groundwater
González Martínez, Farith; Sánchez-Rodas Navarro, Daniel Alejandro; Varela, Nelson; Sandoval, Christopher; Quiñones, Luis; Johnson-Restrepo, Boris (MDPI, 2020-07)
The urinary arsenic metabolites may vary among individuals and the genetic factors have been reported to explain part of the variation. We assessed the influence of polymorphic variants of Arsenic-3-methyl-transferase ... -
Atomic fluorescence spectrometry : a suitable detection technique in speciation studies for arsenic, selenium, antimony and mercury
Sánchez-Rodas Navarro, Daniel Alejandro; Corns, W. T.; Chen, B.; Stockwell, P. B. (Royal Society of Chemistry, 2010-04)
Atomic Fluorescence Spectrometry (AFS) is an ideal detection technique for speciation studies concerning hydride forming elements (mainly As, Se and Sb) and Hg. The analytical features of AFS, such as detection limits below ... -
Contribución de fuentes de material particulado atmosférico en zonas industriales complejas
(Universidad de Huelva, 2022)La contaminación atmosférica procedente de la actividad industrial suscita especial interés en la comunidad científica, dado el impacto que puede provocar en la salud humana y en los ecosistemas. Entre los principales ... -
Contribution of anthropogenic and natural sources in PM10 during North African dust events in Southern Europe
Millán Martínez, María; Sánchez-Rodas Navarro, Daniel Alejandro; Sánchez de la Campa Verdona, Ana María; Rosa Díaz, Jesús de la (Elsevier, 2021)
The influence of North African (NAF) dust events on the air quality at the regional level (12 representative monitoring stations) in Southern Europe during a long time series (2007–2014) was studied. PM10 levels and ... -
Estudio experimental de los parámetros que influyen en el equilibrio químico del electrolito del refino de cobre de Atlantic Copper
(Universidad de Huelva, 2022)El presente trabajo de investigación titulado “Estudio del equilibrio químico en el electrolito de refino de cobre”, llevado a cabo durante cuatro años, es el resultado de la colaboración entre Atlantic Copper SLU y la ... -
Evaluation of the atmospheric impact derived from the evaporation of phosphogypsum acid leachates
(Universidad de Huelva, 2020)The city of Huelva (SW Spain) has been highly industrialized since the 60s. Owing to the promotion of the economic growth of the region, two industrial estates were established near the population. Among several industries ... -
Impact of the SARS-CoV-2 lockdown measures in Southern Spain on PM10 trace element and gaseous pollutant concentrations
Millán Martínez, María; Sánchez-Rodas Navarro, Daniel Alejandro; Sánchez de la Campa Verdona, Ana María; Rosa Díaz, Jesús de la (Elsevier, 2022)
Trace element concentrations within PM10, gaseous pollutants (NO2 and SO2), and PM10 levels were studied during the Covid-19 lockdown at a regional level in Southern Spain (Andalusia). Pollutant concentrations were compared ... -
Origin and speciation of major and trace PM elements in the Barcelona subway system
Font, Oriol; Moreno, Teresa; Querol, X.; Martins, Vania; Sánchez-Rodas Navarro, Daniel Alejandro; Miguel, Eladio de; Capdevila, Marta (Elsevier, 2019)
Wear in train and rail components in the Barcelona subway system includes brake pads, catenary wires, wheels, railways, and motor brushes. These components were characterised to evaluate their contribution to ambient ... -
Removal of Sb Impurities in Copper Electrolyte and Evaluation of As and Fe Species in an Electrorefining Plant
González de las Torres, Ana Isabel; Moats, Michael S.; Ríos Ransanz, Guillermo; Rodríguez Almansa, Ana; Sánchez-Rodas Navarro, Daniel Alejandro (MDPI, 2021-05)
Antimony and arsenic concentrations and their oxidation states (Sb(III), Sb(V), As(III) and As(V)) in copper electrorefining electrolyte can affect copper cathode quality through the formation of floating slimes. A ... -
Source apportionment of potentially toxic PM10 near a vast metallic ore mine and health risk assessment for residents exposed
Boente López, Carlos; Zafra Pérez, Adrián; Fernández Caliani, Juan Carlos; Sánchez de la Campa Verdona, Ana María; Sánchez-Rodas Navarro, Daniel Alejandro; Rosa Díaz, Jesús de la (Elsevier, 2023-03-13)
Mining is an economic activity that traditionally releases large amounts of particulate matter into the atmosphere because of the procedures required to process the mineral. In particular, polymetallic ores are environmentally ...
