“…eolian Saharan dust signature (Grousset et al, 1994;Kylander et al, 2005;Erel and Torren, 2010 Pb = 38.80;Juteau et al, 1986), whereas the signatures outside this group, however, could be associated with an European granite source (Juteau et al, 1986 …”

“…Additionally, the Pb isotope composition provides information on source provenances since natural Pb can be transported in the detrital material or in eolian dust for long distances (Grousset et al, 1994;Grousset and Biscaye, 2005;Kylander et al, 2005). However, anthropogenic Pb contamination can overprint the natural Pb isotope signal (Grousset et al, 1994;Kylander et al, 2005).…”

“…However, anthropogenic Pb contamination can overprint the natural Pb isotope signal (Grousset et al, 1994;Kylander et al, 2005). A particular advantage of the Th-U-Pb system is that binary mixtures form straight linear arrays in Pb-Pb isotope space, and deviations from such arrays imply mixtures involving more than two components.…”

Europe has been continuously polluted throughout the last two millennia. During the Roman Empire, these pollutions were mainly from ore extraction and smelting across Europe. Then, during the Middle Ages and the Early times of Industrial revolution (i.e. 1750), these pollutions extended to coal burning and combustion engine. Belgian ombrotrophic peat bogs have proved an effective archive of these pollutants and provide the opportunity to reconstruct the history of atmospheric deposition in NW Europe.The results of recent and past trace metal accumulation and Pb isotopes from a one-meter peat core (in the Misten peat bog) have been derived using XRF and Nu-plasma MC-ICP-MS. Combined with 14 C and 210 Pb dates these data have enabled us to trace fluxes in anthropogenic pollution back to original Roman times.

“…The precision so reached is about two orders of magnitude lower than the maximum range of variations observed in the nature. Indeed, the 206 Pb/ 207 Pb ratios can vary from ∼ 1.08 in gasoline to ∼ 1.21 for geogenic Pb of Western Europe [14,15], whereas the analytical precision of the same ratio is typically 1-3.10 -3 , at least when the Pb concentrations are sufficiently high. That makes the use of the ICP-MS quite suitable and convenient for quick environmental monitoring.…”

Abstract. Analytical precision of the isotope ratios measured by quadrupole-based ICP-MS is drastically controlled by the lowfrequency noises which originate from nebulisation and vaporisation processes, and from sample introduction systems. The undesirable influence of these latter can be however reduced by choosing efficiently the operating parameters. In the present study, the choice of the stabilisation time necessary in peak jump mode, and the one of the number of sweeps are discussed in the light of noise power spectra obtained with various speeds of the peristaltic pump used as sample introduction system. Obviously, the settings proposed are probably efficient only on our own ICP-MS, but they can be determined without any difficulty on any other equipment, only by following the methodology detailed here. With such guidelines, experimental within-run RSD % were observed following closely those predicted by the counting statistics (∼ 110 %). The isotopic measurements of natural samples (overbank sediments, airborne particulate matter, lichens and rainwater) exhibited fair accuracy and good reproducibility, making highly convenient the use of the ICP-MS, at least in an environmental purpose.Keywords.
