“…One advantage of using geostatistics is to know or estimate the value of a variable in a unsampled site, regarding the variable values of points near the site of interest, which is called interpolation (Aguilar et al, 2013;Ascione, Moroni, Petrò, & Romano, 2013;Bautista, Cram-Heydrich, & Sommer-Cervantes, 2011;Rodríguez-Martín, Ramos-Miras, Boluda, & Gil, 2013). A limited number of sampling sites, for example 100, allows to estimate the values of a variable in 8,000 unsampled sites, making possible to create maps to identify the spatial distribution of HM (Delgado et al, 2010;Juang, Chen, & Lee, 2004 interpolación (Aguilar et al, 2013;Ascione, Moroni, Petrò, & Romano, 2013;Bautista, Cram-Heydrich, & Sommer-Cervantes, 2011;Rodríguez-Martín, RamosMiras, Boluda, & Gil, 2013).…”

In Ensenada Baja California, ships and vehicles produce particles with heavy metals. These particles are blown by the wind and deposited on the soil becoming urban dust. Heavy metals may affect the health of the population, so a quick diagnosis is required to find a solution to this problem. The aim of this study is to identify those areas of higher pollution within the city. A total of 86 urban dust samples were sampled on diferent substrates (soil, cement and asphalt). Heavy metals were analyzed by X-ray fluorescence. Differences among substrates were identified by analysis of variance. The analysis of ordinary Kriging interpolation was performed to estimate the spatial distribution of heavy metals. Asphalt contains higher concentration of Cr, Ni, Pb and Zn; cement contains higher concentrations of Cu and V; and soil contains higher concentrations of Rb. The map which includes the classes with higher concentration of heavy metals shows that the southwest area of the city is the most polluted area due to port and transpeninsular highway. ResumenE n Ensenada, Baja California, los barcos y vehículos emiten partículas con metales pesados. Las partículas se transportan con el viento y se depositan en el suelo, donde se mezclan con él dando lugar a los polvos urbanos. Los metales pesados pueden afectar la salud de la población, por lo que se requiere un diagnóstico rápido para encontrar soluciones. El objetivo de este trabajo fue identificar las zonas con mayor contaminación en la ciudad. Se tomaron 86 muestras de polvo urbano sobre diferentes sustratos (suelo, cemento y asfalto). Los metales se analizaron mediante fluorescencia de rayos X. Las diferencias entre los sustratos se identificaron mediante un análisis de varianza. Por otra parte, se hizo un análisis para conocer la distribución espacial de los metales pesados, utilizando la interpolación con kriging ordinario. El asfalto contiene las mayores concentraciones de Cr, Ni, Pb y Zn; el cemento contiene mayores concentracions de Cu y V; y el suelo es el que más Rb contiene. El mapa que integra las clases de mayor concentración de metales indica que la zona suroeste, donde se localiza el puerto y pasa la carretera transpeninsular, es la más contaminada.

“…Finally, the high content of As in the interchangeable and oxidized fractions, higher than 40% in soil, can be responsible for the high contamination of As in the three vegetable tested in comparison with the Spanish one. The Spanish samples are in the level reported for plants growing in noncontaminated soils [39,40]. It is relevant that only As (III) and As (V) are present in carrots and quinoa (Figures 2a-e).…”

Studies on the bioavailability of As, of impacted vegetables; and As bioaccesibility in the edible parts of carrots (daucus carota), beets (beta vulgaris) and quinoa (chenopodium) growing in polluted soils thought "in vitro" gastrointestinal process; the As speciation both in the edible parts of vegetables and in their gastrointestinal extracts have been performed. Elemental analysis and As speciation have been performed by ICP-MS and LC-ICP-MS, respectively. The Arsenic recovery after the in vitro gastrointestinal digestion was from 98, 90 and 40% for carrots, beets and quinoa, respectively; with no significant transformation of original As species. These studies provide a clearer understanding of the impact that As and other contaminant elements may present in the population of this high polluted Chilean region.
