Additional Certified Values for CCRMP Soils SO‐1 to ‐4

Abstract

New mean values for up to 11 major and minor and up to 11 trace elements in soils SO‐1 to SO4 have been calculated by two procedures. Analytical results received by CCRMP subsequent to the certification program of 1979 were included. In one instance, the same procedure as used for certification wherein all results except those rejected on chemical and/or statistical considerations was followed, but little improvement over the 1979 calculations was obtained. The other procedure is proposed by the authors for use in identifying concentration range intervals wherein maximum interlaboratory consensus is observed. The application of this procedure has permitted the certification of the four soils for the content of 24 elements not previously certified.

Rock glaciers in crystalline catchments: Hidden permafrost‐related threats to alpine headwater lakes

“…Elemental composition of the rock and sediment samples (fine‐grinded powder in Chemplex SpectroMicro ® Sample Cups 3110) and the invertebrate samples (felt‐like aggregates in Chemplex SpectroMicro ® Sample Cups 3110 with 3 μm‐thick Prolene films) was assayed by energy dispersive X‐ray fluorescence (EDXRF) analysis using a Spectro XEPOS Plus spectrometer and calibration models based on the fundamental parameter methods (Tessadri, ). The experimental parameters were obtained by calibration of the whole system by means of the CCRMP reference soils SO‐1, SO‐2, SO‐3, and SO‐4 (Steger, Bowman, & McKeague, ). Results obtained on five replicate samples demonstrate that the relative standard deviation on the metal assay is better than ±10%.…”
