-
(Hindawi, 2014)Measurements of carbonaceous aerosols in South American cities are limited, and most existing data are of short term and limited to only a few locations. For 6 years (2002–2007), concentrations of fine particulate matter ...
-
(2013)Two methods to measure mercury concentration in soil are compared, and their compliance with international standards is determined: cold vapour atomic absorption spectrometry and thermal decomposition, amalgamation and ...
-
(Universidad de Chile, 2018)A la fecha, 12 de las 15 regiones de Chile conforman zonas saturadas de MP10 y/o MP2.5, lo que deja en evidencia el grave problema ambiental que enfrenta el país. En la actualidad, el monitoreo de la calidad del aire en ...
-
(Universidad de Chile, 2009)El uso de materiales de referencia es una opción para otorgar trazabilidad y comparabilidad en las mediciones de los laboratorios vinculados a la contaminación marina acuícola. Durante este trabajo se elaboró un candidato ...
-
(Elsevier Inc., 2013)It is well-known that small-scale artisanal mining is a source of mercury emissions into the environment, mainly from the use of rudimentary technologies that use mercury amalgamation in the extraction process. Mines near ...
-
(Institute of Medical Research & Occupational Health, Croacia, 2022)We investigated the influence of local meteorological conditions and number of visitors on ambient particulate matter (PM) mass concentrations and particle fraction ratios at the Plitvice Lakes National Park between July ...
-
(Elsevier, 2014)The long-term trends and spatial variability of PM2.5 and PM10 over the period between 2000 and 2012 in the Santiago Metropolitan Area, Chile are studied. The annual PM10 and PM2.5 mass concentration ranged between 76 ...
-
(Springer Netherlands, 2018)© 2017, Springer Science+Business Media B.V. Landfill fires are relatively frequent incidents that can result in severe environmental impacts. On the morning of January 15, 2016, a fire occurred at the Santa Marta landfill ...
-
(American Geophysical Union, 2013)Observations were performed in 12 communities of Central Chile in order to determine the horizontal gradients of ozone in the Santiago Basin and surrounding valleys. Higher ozone mixing ratios were found northeast of the ...
-
(Elsevier Ltd., 2011-10-12)The study examined weekdayeweekend differences in ozone, NOx (NO and NO2) and VOC concentrations in Santiago, Chile, from 1999 to 2007. The results provide evidence for the occurrence of an atmospheric phenomenon that ...
-
(Springer, 2015)The relationships between ozone (O-3) and its precursors, nitrogen oxides (NO (x) ) and volatile organic compounds (VOCs), were investigated in the VIR region (34A degrees 10' S, 71A degrees 36' W), referred to as Libertador ...
-
(Springer Science and Business Media Netherlands, 2014)The Valparaiso Region is characterized by the presence of air sheds that modulate the general atmospheric circulation with local winds. The ozone concentration in the region increases from the west coast toward the mountainous ...
-
(Universidad de Chile, 2016)El conocimiento de la circulación del aire en Santiago aporta información sobre el Comportamiento atmosférico de la Macro Zona Central de Chile. Según como se muevan las masas de aire será posible discriminar zonas ...
-
(2012)The present work presents a measurement uncertainty evaluation according to Guide to the Expression of Uncertainty in Measurement (GUM) of the concentration of the cations K + and Li + and anions NO 3 -2 and SO 4 -2 in ...
