Palabras clave: contaminación, kriging indicador, norma oficial mexicana, plomo, vanadio RESUMEN Siete millones de personas mueren al año por cáncer relacionado con la contaminación ambiental. El polvo urbano (PU) contiene partículas < 10 µm que afectan la salud humana. En la Ciudad de México (CDMX) existe sólo un estudio de PU. El objetivo de este estudio fue identificar las zonas de la CDMX con mayor probabilidad de contaminación por metales pesados (MP) en el PU. Se recolectaron 89 muestras de PU y se midió la concentración de MP por fluorescencia de rayos X. El análisis espacial se realizó mediante interpolación con kriging indicador. El porcentaje de la superficie con mayor probabilidad de que los MP superen los límites máximos permitidos (LMP) fueron: Cr (LMP 280 mg/kg), 0.55 %, suroeste; Cr (LMP 64 mg/kg), 89 %, toda la CDMX y la mayoría de las áreas conurbadas (AC); Cu, 17 %, 11 delegaciones y AC del norte; Ni, 13 %, centro y suroeste; Pb (LMP 140 mg/kg), 17.5 %, delegaciones céntricas y AC del noroeste; Pb (LMP 400 mg/kg), 2.2 %, delegaciones céntricas y AC del noroeste; V, 26 %, delegaciones céntricas y del sur, así como AC del noreste; Zn, 21 %, delegaciones céntricas y AC del norte. Los elementos con mayor número de sitios y superficie contaminada son: Cr, Zn, Cu y Pb. Los sitios con mayor superficie de sobreposición de MP son aquellos con asociaciones entre Cu y Zn (15 %), y Cu y Pb (13 %). Las delegaciones Cuauhtémoc, Venustiano Carranza y Gustavo A. Madero son las más contaminadas con metales pesados. ABSTRACTSeven million people die per year of cancer related to environmental pollution. Urban dust (UD) contains particles smaller than 10 μm that affect human health. In Mexico City (CDMX) only one study on UD has been conducted. The objective of this study was to identify the areas most likely to be contaminated by heavy metals (HM) contained in the UD of CDMX. Eighty nine UD samples were collected; the analysis of the HM concentration was made by X-ray fluorescence, and spatial analysis by interpolation with kriging indicator. The percentage of the area with the highest probability that HMs exceeded the maximum permitted limits (MPL) were: Cr (MPL 280 mg/kg), 0.55 %, southwest of the CDMX; Cr (MPL 64 mg/kg), 89 %, all CDMX and most of the conurbated areas (CA); Cu, 17 %, 11 municipalities and the northern CA; Ni, 13 %, center and southwest of the CDMX; Pb (MPL 140 mg/kg), 17.5 %, centric municipalities and the northwest CA; Pb (MPL 400 mg/kg), 2.2 %, centric municipalities and the northwest CA; V, 26 %, centric and southern municipalities and the northeast CA; Zn, 21 %, centric municipalities and the northern CA. Elements with a greater number of sites and contaminated surface are: Cr, Zn, Cu and Pb. The largest HM overlapping sites are those with Cu and Zn associations (15 %), and Cu and Pb associations (13 %). The municipalities Cuauhtémoc, Venustiano Carranza and Gustavo A. Madero are the most contaminated with heavy metals.

“…The mineral phases present in the MTs samples were identified and quantified using the Philips PW1130/90 X-ray diffractometer (XRD), and the geochemical composition oxides and potentially toxic elements (PTEs) of the MTs sample were measured by Panalytical Axios wavelength-dispersive X-ray fluorescence (XRF). The details of sample preparation, instrumentation condition for each method are described by Beckhoff [17] and Compton [18].…”

Static Test-Based Acid Rock Drainage Formation Potential of Metalliferous Tailings from O’Kiep, South Africa

One of the environmental challenges in O'Kiep is the increased levels of potentially toxic elements (PTEs) in metalliferous tailings (MTs), which may result in acid rock drainage (ARD) through oxidation. In this study, laboratory-based static tests were conducted on MTs to predict the risk of acid rock drainage potential (ARDP). Mineralogical analysis of the MTs showed that the MTs consisted mainly of quartz, microline, muscovite, albite, anorthite, magnetite, magnesioferrite, gypsum and halloysite-10A. The major oxides, i.

“…Laboratory XRF is a well-established and frequently used technique in obtaining diagnostic compositional data on geological samples (Beckhoff et al, 2006;von Hevesy, 1932;Jenkins et al, 1995;Jenkins, 1999;Norrish & Hutton, 1969;Norrish & Chappell, 1977;Parrish, 1956;Shaw, 1952;etc.). Recently, developments in x-ray tube and detector technologies have resulted in miniaturized, field-portable instruments that enable new applications.…”

Field portable instrumentation, such as in situ geochemical analyzers or broader field of view instruments like multispectral imagers or other imaging capabilities, has the potential to dramatically increase the science return of a planetary surface exploration mission. However, more work is needed to determine how emerging portable technologies should be designed and implemented into evolving mission architectures. This work summarizes the efforts of the RIS4E (Remote, In Situ and Synchrotron Studies for Science and Exploration) SSERVI (Solar System Exploration Research Virtual Institute) team in investigating how field portable instruments should be including into planning for future exploration EVAs (extravehicular activities). EVA crews of geologists and astronauts tested a variety of portable and handheld technologies at both the December 1974 lava flow, Kilauea Volcano, Hawai'i, and Kilbourne Hole, New Mexico, both of which are planetary analog sites. The timeline data gathered during instrument deployment were then mapped onto EVA timelines used in large‐scale NASA planetary surface exploration analog missions. Results and recommendations for future instrument hardware and software development are discussed, as is the operational framework necessary for incorporating in situ analytical capabilities into future planetary surface exploration.
