“…PIXE is an X‐ray spectrometric technique where the X‐ray spectrum is excited by energetic protons ionising the inner shell electrons in the target atoms. It is a sensitive and convenient method for the determination of relatively low concentrations of elements such as the transition metals in samples of limited size (Aldape et al. 1999, Menzel et al.…”

Particle-induced X-ray emission (PIXE) and ICP-AES can be combined to obtain a wider range of detected elements, augment previous data and ⁄ or to verify measured concentrations of heavy and trace metals in geological samples. Intercomparison of data sets generated by multiple techniques is challenging due to the differing processes and methods of each technique. Here, we compare elemental data obtained by both techniques for aeolian dust from Owens (Dry) Lake, California. Nineteen elements were detected by PIXE, sixteen by ICP-AES and ten elements were detected by both techniques. Statistical analyses of data set groupings illustrated which parameters differed significantly between PIXE and ICP-AES. Relative variation (%) showed that PIXE gave higher concentrations than ICP-AES for Al, As, Cu, Fe, K, Mn, Ni, Sr, Ti and Zn in all samples. For As, Cu, Sr and Zn, relative variation was variable between the techniques. PIXE detection limits exceeded ICP-AES concentrations for Ba, Cd, Co, Cr, Pb and Mo. Low ICP-AES percentage recoveries of Al, Fe, K, Mn and Ti for NIST SRM 2710 indicated incomplete dissolution during digestion (EPA Method 3050B), since elements were bound in silicate structures. Variability between the two data sets is explained by differences between analytical techniques, sample preparation methods and ⁄ or variability in sample matrices.

“…In Mexico, the metal concentration in PM has been investigated in Mexico City (Chow et al 2002a;Mugica et al 2008;Querol et al 2008), urban areas of Tampico (Flores-Rangel et al 2007a), Monterrey (Aldape et al 1999a), Hidalgo (Aldape et al 1999b), San Luis Potosí (Pina et al 2000), Colima (Miranda et al 2004), Tijuana (Minguillón et al 2014), and industrial areas of Altamira (Flores-Rangel et al 2007b), Salamanca (Vega et al 2007), andPuebla (MoralesGarcía et al 2014). This work presents novel results of PM 10 and metal concentrations in Tampico, Mexico, during 2004.…”

Concentrations of Cd, Cr, Cu, Fe, Mn, Ni, Pb, Ti, V, and Zn in particulate matter (PM) 10 ambient air samples were determined for the urban zone of Tampico, Mexico every 6 days during 2004. A Wedding and Associates PM 10 highvolume sampler was used to collect the particles on quartz and glass fiber filters. A Thermo Jarrel Ash inductively coupled plasma-optical emission spectrometer (ICP-OES) was used to identify and quantify metals in PM 10 according to the USEPA-IO 3.1 method. A scanning electron microscope with an energy dispersive spectrometer (SEM-EDS) was used to analyze the elemental composition, size, and morphology of atmospheric particles. Principal component factor analysis (PCFA) was used to study the sources of PM 10 and metals. PM 10 and Pb concentrations in Tampico did not exceed the Mexican standard value of 120 and 1.5 μg m −3 in 24 h, respectively. PM 10 concentrations ranged from 12 to 47 μg m −3 . The results for Cd, Cr, and Cu are associated to the presence of an industrial source near the sampling site. V and Zn and likely Pb and Ni are related to a refinery. Fe and Ti are associated to natural sources, whereas Cu, Fe, Ni, Pb, and Zn are associated to the storage and transportation of minerals near the sampling zone. Mn is associated to a ferromanganese manufacturing industry and to the refinery. The SEM-EDS micrographs show porous spherical particles rich in V and Ni and smooth spherical particles rich in C and O.

“…Although the aerosols have been widely studied around the world (Lopes et al 2006;Okuda et al 2004;Chen et al 2003), in México this material has been principally studied in México City (Chow et al 2002b;Mugica et al 2002;Diaz et al 2002;Barfoot et al 1984) and in some other cities like Monterrey (Aldape et al 1999b), Hidalgo (Aldape et al 1999a), San Luis Potosi (Aragon-Piña et al 2002), and Colima (Miranda et al 2004). The RAMA 1 was established in 1986, but historical databases are available since 1990 (SIMAT 2007).…”

With the aim to know possible risks to the population, Cd, Co, Cr, Cu, Mn, Ni, Pb, and Tl were determined for the first time in airborne samples of particulate matter in an urban zone in Tampico, México, during the winter of 2003. The 24-hour PM 10 samples were collected every 6 days on quartz-filters by using a high volume sampler and analyzed by Inductively Coupled Plasma Optical Emission Spectrometer. Standard reference material was used to verify metal recovery. The maximum PM 10 and lead concentrations were 12.05 and 0.040 µg/m 3 , respectively, not exceeding Méxican standard values. The greatest metal concentration was that of manganese with 0.90 µg/m 3 , followed by Cu and Ni with 0.17 and 0.012 µg/m 3 , respectively. Agglomerates, well-defined particles, and heavy metals (e .g., Mn and Cu) were found in PM 10 using Scanning Electron Microscopy and Energy Dispersive Spectroscopy. Meteorological conditions associated with the sampling period showed that Pb and Ni are being continuously emitted, and that Mn, Cu, and Co could come from one industry located to the WSW of the region. All of these concentrations do not constitute a potential risk to human health, although it is necessary to continue studying the high concentrations of Mn and Cu in longer sampling periods.
