Forty‐Nine Major and Trace Element Concentrations Measured in Soil Reference Materials NIST SRM 2586, 2587, 2709a, 2710a and 2711a Using ICP‐MS and Wavelength Dispersive‐XRF

Abstract

Excellent agreement was noted in the concentration of major and trace elements in five NIST (National Institute for Science and Technology) soil reference materials (NIST SRM 2586, 2587, 2709a, 2710a and 2711a between measurement results from wavelength dispersive-XRF and ICP-MS from two independent laboratories, and NIST certificate of analysis and literature data. We describe the variability in concentrations of up to forty-nine elements (plus loss on ignition) and provide values for up to twentyone elements previously uncharacterised by NIST in these soil RMs. The additional characterisation provided in this investigation can be utilised to reduce the measurement bias of custom calibration routines and improve the quality of control checks developed using these NIST RMs.Keywords: National Institute for Science and Technology, inductively coupled plasma-mass spectrometry. wavelength-dispersive X-ray fluorescence, WD-XRF, calibration materials, soil, urban agriculture.

Nous d ecrivons la variabilit e des concentrations allant jusqu' a quarante-neuf el ements (plus la perte au feu). En outre, nous fournissons des valeurs pour un maximum de vingt et un des el ements pr ec edemment caract eris es par le NIST dans ces mat eriaux de r ef erence du sol. La caract erisation suppl ementaire fournie dans cette enquête peutêtre utilis e pour r eduire le biais de mesure des routines d' etalonnage personnalis es et d'am eliorer la qualit e des contrôles d evelopp es en utilisant ces mat eriaux de r ef erence.

“…The soil analysis followed the United States Environmental Protection Agency (USEPA) Method 6200; field portable X-Ray fluorescence spectrometry for the determination of elemental concentrations in sediment and soil protocol 24. The XRF was calibrated using NIST 2711 standard and system checked each day prior to use 25. An aliquot of the sieved sample (~2 g) was placed in a small (approximately 30 mm) polyethylene container so it was three quarters full and sealed at both ends using a mylar film.…”

Hominin raw material procurement in the Oldowan-Acheulean transition at Olduvai Gorge

“…Each glass bead was then analyzed in a Bruker S4 Pioneer Wavelength Dispersive X-ray Fluorescence Spectrometer (WD-XRF) for major, minor, and some trace elements. Concentrations were calculated using a calibration derived from eleven USGS rock standards (igneous and sedimentary), using the methods of McHenry (2009) and further detailed in Byers et al (2016). Concentrations are reported for all elements for which the calculated concentration exceeds two times the lower limit of detection (LLD) and for which the analytical error is less than 12% (for trace elements) or 2% (for major elements).…”

“…Following on these studies of early Pleistocene hominin raw material procurement patterns in eastern Africa, our aim is to present here a systematic analysis of rock types used by Olduvai hominins during the stratigraphic interval where the emergence of the Acheulean took place, at ~1.7-1.4 Ma (McHenry et al, 2016). This transition occurred at Olduvai Gorge in the interval spanning the LAS and the Middle Augitic Sandstone (McHenry, submitted; Stanistreet et al, submitted), and over the last few years the Olduvai Geochronology Archaeology Project (OGAP) has investigated several paleoanthropological localities in Lower, Middle, and Upper Bed II to address the chrono-stratigraphic, ecological, environmental, and behavioral patterns involved in the disappearance of the Oldowan and the advent of the Acheulean.…”
