Yield reduction and arsenic accumulation in potatoes (Solanum tuberosum L.) in an arsenic contaminated soil
(Universidad Nacional de Colombia, 2015-09-01)
The different levels of arsenic (As) had a significant effect on the yield, yield reduction and As accumulation of different potato varieties. The yield was negatively affected by the As contamination and decreased with ...
Attention deficit hyperactivity disorder and its association with heavy metals in children from northern Chile
(Elsevier, 2020)
Introduction: Exposure to lead and arsenic has been associated with child behavior problems. In Arica, a northern city of Chile, the natural presence of arsenic in water has been registered. Also, the city has a history ...
Determination of arsenic (iii) by differential pulse polarography in the waters of Camarones area, Chile
(Sociedad Chilena de Quimica, 2013)
As (III) was determined by differential pulse polarography (DPP) in 1 mol L-1 HCl as supporting electrolyte. For quantification, the -0.35 V peak (versus Ag/AgCl) was chosen. The obtained detection and quantification limits ...
Removal of arsenic and iron from acidic water using zeolite and limestone: batch and column studies
(Springer, 2017)
Zeolite and limestone were tested for their capability of removing As and Fe from acidic water in batch and column experiments. Synthetic acidic water with 3 mg/L As and 50 or 100 mg/L Fe at pH = 2 was used in the column ...
Circulating Arsenic is Associated with Long-Term Risk of Graft Failure in Kidney Transplant Recipients: A Prospective Cohort Study
(MDPI, 2020)
Arsenic is toxic to many organ systems, the kidney being the most sensitive target organ. We aimed to investigate whether, in kidney transplant recipients (KTRs), the nephrotoxic exposure to arsenic could represent an ...
Smoking habit and genetic factors associated with lung cancer in a population highly exposed to arsenic
(ELSEVIER, 2005-10-15)
In order to find some relationship between genetic differences in metabolic activation and detoxification of environmental carcinogens and host susceptibility to chemically induced cancers, we have investigated the ...
Preliminary physical chemical characterization of river waters and sediments affected by copper mining activity in central chile. Application of multivariate analysis
(SOC CHILENA QUIMICA, 2007-09)
The concentration of trace elements and other analytes of environmental interest was determined in waters and sediments of the Coya and Cachapoal rivers (VI Region, Central Chile), which corresponds to a location highly ...
Human adaptation to arsenic in Andean populations of the Atacama Desert
(Wiley-Liss Inc., 2017)
© 2017 Wiley Periodicals, Inc. Objectives: Quebrada Camarones, in the Atacama Desert, has the highest arsenic levels in the Americas (>1,000 µg/L). However, the Camarones people have subsisted in this adverse environment ...
Arsenic speciation in water samples containing high levels of copper: removal of copper interference affecting arsine generation by continuous flow solid phase chelation
(SPRINGER HEIDELBERG, 2005-04)
A simple continuous flow method is proposed to eliminate copper interference in arsenic speciation by hydride generation, based on the selective retention of this interfering ion in an iminodiacetate chelating resin previous ...
Extractable copper, arsenic and antimony by EDTA solution from agricultural Chilean soils and its transfer to alfalfa plants (Medicago sativa L.)
(ROYAL SOC CHEMISTRY, 2004)
Following our research on copper, arsenic and antimony in Chilean ecosystems, a study to understand the mobility and transport of these elements from soil to plants was carried out. So, the aim of this study, which follows ...
