“…The results are presented in Table 3 ranged from 348 ng L -1 (Ce) to 1.8 ng L -1 (Tm) and the precisions (2 × RSD) ranged from 4.5% (Nd) to 43% (Yb) (N = 5). The values were consistent with the reported values (Yeghicheyan et al, 2001;Shimamura et al, 2007;Dick et al, 2008) and those for non-diluted samples.…”

Rare earth element (REE) concentrations were determined in 32 rainfall events collected in suburban Tokyo. Two or more samples were collected for 13 events out of 32 events. A pre-concentration method was applied using a chelate resin solid phase extraction column. Good and uniform recoveries for REEs (Y to Lu, 99~101% at pH = 3.7~4.0) were obtained. Detection limits reached as low as 0.001 ng L -1 (for Tb) with a 30 fold pre-concentration using a conventional Q-pole ICP-MS. Clear La and Gd excesses (definition is in the text) were evident in many cases. Y, Eu, Lu and Yb excesses may also exist in some events. In some events where multiple samplings were performed, crust normalized REE patterns changed during the rainfall events. These are the first evidences of clear REE pattern variations during the same rainfall events. The initial and final stage of some rainfall events may have different origins for the REEs. The correlations among the REEs with respect to logarithmic concentrations indicate that most of the REEs are of natural origin while La and Gd may have common anthropogenic components. We propose that materials for high refractive index and low dispersion optical glass production processes could be potential sources of La and Gd excesses because 1) La and Gd excesses are correlated, 2) other sources such as a cracking catalyst for petroleum refining or a contrast agent of magnetic resonance imaging cannot explain the excesses.

“…Indium and rhenium were used as external standards. The international geostandard SLRS-4 (Riverine Water Reference Material for Trace Metals certified by the National Research Council of Canada) was used to check the accuracy and reproducibility of each analysis (Yeghicheyan et al, 2001). We obtained a good agreement between replicated measurements of SLRS-4 and the certified values (relative difference < 10% SD on repeated measurements), except for B and P (30%).…”

-This work represents a concerted effort aimed at understanding the microbiological and chemical evolution of a small boreal lake during the diurnal cycle of photosynthesis. We studied diurnal variation of y 40 dissolved macro-and trace elements, organic carbon and bacterial population dynamics in the surface and bottom water layer of the shallow Vilno Lake in the White Sea basin. Four-days continuous measurements with 6 h sampling steps both at the surface (0.5 m) and on the bottom (4.0 m depth) during no-bloom periods revealed constant concentrations (within ¡ 20-30%) of all major elements (Na, Mg, Si, K, Ca), organic and inorganic carbon and most trace elements (B, V, Cr, Fe, Cu, Ga, As, Rb, Sr, Y, Zr, Sb, Cs, Ba, all REEs, Hf, Pb, Th, U). At the same time, the concentration of some biologically important trace metals (Mo, Mn, Co, Cd) was subjected to variations partially reflecting the change of bacterioplankton concentration. This work enables two types of element behavior to be distinguished during photosynthesis in the water column -constant concentration and sinusoidal variations -depending on their speciation in solution and their affinity to aquatic microorganisms.

“…P is not certified in this CRM. An indicative concentration was published in Yeghicheyan et al (2001), but a more recent value [P] 4 was retrieved from the SLRS-5/SLRS-4 concentration ratio R P published in Heimburger et al (2013), and its concentration [P] 5 in SLRS-5 published in Yeghicheyan et al (2013). These values are respectively equal to R P = 1.43 ± 0.02 and [P] 5 = 8.2 ± 3 µg L −1 .…”

“…The following elements were determined using the atomic emission line (wavelength in brackets, nm): Ca (422.673), Sr (407.771), Ba (455.403), Mn (257.61),Fe (259.94),Al (396.152), and P (213.628). The instrument was calibrated on each line using standard solutions, and was checked five times with the certified reference material (CRM) SLRS-4 (NRC, Canada, certified values reported in Yeghicheyan et al, 2001. P is not certified in this CRM.…”

A fine fraction of soil used as an aerosol analogue during the DUNE experiment: sequential solubility in water, decreasing pH step-by-step

Abstract.A soil sample collected in a desert aerosol source area near Douz (southern Tunisia) was dry-sieved at 20 µm in order to extract the fraction similar to a wind-generated aerosol, and was used to seed mesocosms during the DUNE experiment (a DUst experiment in a low Nutrient, low chlorophyll Ecosystem). In this work, said "aerosol-like" fine dust was sequentially leached by short contacts with water at initial pHs, decreasing from seven to one, representing various wet environmental conditions. For each step, the solubility of a given element is calculated as the amount of its dissolved fraction, relative to its total amount. The evolution of this fractional solubility from the highest to lowest pHs provides information on the chemical strength needed to solubilise a given element and its lability. The behaviour of the elemental solubility was sorted into two groups: (1) Ca, Sr, Ba, Mn, and P, with a solubility between 23 % and 70 %, and a maximum sequential solubility at pH 3; (2) Al and Fe, with a solubility of less than 2 % and the highest release at pH 1. Similar solubility patterns in group 1 for Ca, P, and Mn suggest a possible association of the elements in the same minerals, most probably carbonates.
