(Universidad de Chile, 2015)La Antártica es el continente más austral de la tierra, contiene cerca del 80% de las reservas de agua dulce del planeta y presenta una serie de condiciones extremas, como bajas temperaturas y alta radiación ultravioleta. ...
-
(Oxford University Press, 2016)Use of unauthorized synthetic drugs is a serious, forensic, regulatory and public health issue. In this scenario, consumption of drug-impregnated blotters is very frequent. For decades, blotters have been generally impregnated ...
-
(2013)Atrazine sorption was studied in six Andisol and Ultisol soils. Humic and fulvic acids and humin contributions were established. Sorption on soils was well described by the Freundlich model. Kf values ranged from 2.2−15.6 ...
-
(Elsevier, 2012-02-03)In the present work three different SPME fibers have been investigated for simultaneous determination of methyl-, butyl- and phenyltins by using gas chromatography-pulsed flame photometer detection (GC-PFPD). The optimal ...
-
(Elsevier, 2020)In this work, an analytical method for deltamethrin determination in natural waters based on photochemicallyinduced fluorescence coupled to third-order/four-way calibration was evaluated and compared with secondorder/three-way ...
-
(Universidad de Chile, 2013-03)Los hidrocarburos aromáticos policíclicos (PAHs), generados por combustión incompleta de materia orgánica, presentan particular interés debido a sus características cancerígenas y/o mutagénicas. Para el ser humano una de ...
-
(Universidad de Chile, 2014)Imidacloprid pertenece a un nuevo tipo de pesticidas llamados neonicotinoides. Estos son pesticidas sistémicos que se distribuyen dentro de las plantas después de ser absorbidos por ellas. Se les utiliza mediante rociado ...
-
(Universidad de Chile, 2011)La utilización de antimicrobianos por parte de la industria del salmón, ha sido en respuesta a la necesidad del control de ataques de patógenos oportunistas dado los sistemas de cultivo intensivos utilizados por esta ...
-
(ROYAL SOC CHEMISTRY, 2001)Two sensitive analytical atomic spectrometry methods, electrothermal atomic absorption spectrometry (ET-AAS) and hydride generation coupled to atomic fluorescence spectroscopy (HG-AFS), were optimized for determining total ...
-
(Elsevier, 2018)The effect of the composition of twelve varieties of extra virgin olive oils (EVOOs) on their differentiation based in agronomic criteria and on the antioxidant capacity was studied. Principal component analysis permitted ...
-
(Universidad de Chile, 2008)Los pesticidas organofosforados son ampliamente utilizados en el control de plagas en el área agrícola. Sin embargo, debido a sus efectos nocivos para la salud y capacidad de bioacumulación se han desarrollado normas que ...
-
(Universidad de Chile, 2014)Los Hidrocarburos aromáticos policíclicos (HAP) son un grupo de compuestos orgánicos constituidos por 2 o más anillos aromáticos simples unidos, que no contienen heteroátomos ni otros sustituyentes. Generan diversos ...
-
(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 ...
-
(Springer, 2017)Cyclodextrins (CDs) can improve the apparent solubility and bioavailability of a variety of organic compounds through the formation of inclusion complexes; accordingly, they are suitable for application in innovative ...
-
(Frontiers media SA, 2017)Antarctica is an attractive target for human exploration and scientific investigation, however the negative effects of human activity on this continent are long lasting and can have serious consequences on the native ...
-
(Elsevier, 2015)A new biomimetic approach for triclosan (TCS) was developed based on the leaching of the analyte from different biosolid-amended agricultural soils and the subsequent extraction of the leachates, using a rotating disk ...
-
(Universidad de ChileCyberDocs, 2009)El aceite de oliva es un aceite natural que constituye una pieza fundamental de la dieta mediterránea. Se caracteriza por sus propiedades nutricionales y efectos saludables, debido a su alto contenido de antioxidantes y ...
-
(Frontiers media SA, 2018)Recently, we reported the production of Cadmium sulfide (CdS) fluorescent semiconductor nanoparticles (quantum dots, QDs) by acidophilic bacteria of the Acidithiobacillus genus. Here, we report that the addition of inorganic ...
-
(Universidad de Chile, 2012-06)Un gran número de intoxicaciones agudas letales se producen en el país debido al uso indebido de métodos químicos para el control de plagas. Sin embargo, no se encuentran implementados protocolos confiables para establecer ...
-
(Elsevier, 2020)Some minor constituents of honey samples were determined through a fluorometric-chemical characterization method and related multifactorially with their antibacterial activity against Staphylococcus aureus and Pseudomonas ...
