Abstract Radiocarbon dating archaeological bone typically requires 300–1000 mg material using standard protocols. We report the results of reducing sample size at both pretreatment and 14 C measurement stages for eight bones spanning radiocarbon timescale different levels preservation. adapted our collagen extraction protocol specifically <100 material. Collagen was extracted least twice (from 37–100 material) from each bone. aliquots containing μg carbon were measured in replicate gas...
We present new 14C results measured on subfossil Scots Pines recovered in the eroded banks of Drouzet watercourse Southern French Alps. About 400 ages have been analysed 15 trees sampled at annual resolution. The resulting Δ14C record exhibits an abrupt spike occurring a single year 14 300-14 299 cal yr BP and century-long event between 13.9 kyr BP. In order to identify causes these events, we compare with simulations based 10Be Greenland ice used as input carbon cycle model. correspondence...
Abstract. Atmospheric particulate matter (PM) affects the climate in various ways and has a negative impact on human health. In populated mountain valleys Alpine regions, emissions from road traffic contribute to carbonaceous aerosols, but residential wood burning can be another source of PM during winter. We determine contribution fossil non-fossil carbon sources by measuring radiocarbon aerosols using recently installed AixMICADAS facility. The accelerator mass spectrometer is coupled an...
Abstract The AixMICADAS facility is in part dedicated to research on radiocarbon ( 14 C) calibration by means of various archives. For this purpose, we are improving upon the capacity accurately date subfossil wood. In current study, nine chemical pretreatment protocols tested six wood samples known ages. optimization based C ages, 13 C/ 12 ratios, carbon % and overall mass yield leads us favor acid-base-acid-bleaching (ABA-B). This efficient method shown provide a residue holocellulose with...
Abstract RI‐OH (ring index of hydroxylated tetraethers) has recently been proposed to reconstruct paleotemperatures in middle‐ low‐latitude marginal seas. However, barely tested seas under substantial terrigenous inputs. Here we analyze tetraether lipids two adjacent marine cores from the Gulf Lions. We then test for first time paleothermometer 160 9 ka BP western Mediterranean Sea. While inputs prevent TEX 86 (TetraEther indeX tetraethers consisting carbon atoms) behaving as a...
Abstract For many of archaeology’s rarest and most enigmatic bone artifacts (e.g. human remains, ornaments, worked bone), the destruction 500 mg material necessary for direct accelerator mass spectrometry (AMS) dating on graphite targets would cause irreparable damage; therefore have not been directly dated. The recently improved gas ion source MICADAS (MIni CArbon DAting System) offers a solution to this problem by measuring gaseous samples 5–100 µg carbon at level precision previously...
Used as a solvent in the dry-cleaning industry, tetrachloroethylene (C(2)Cl(4)) can be pollutant of residential indoor air, which cause long-term harmful exposures because its neurotoxicity and probable carcinogenicity. In France, facilities are integrated urban environments (shopping malls, buildings) contribute to C(2)Cl(4) exposure for customers residents. This exploratory work presents results from five studies carried out one shopping mall four buildings housing facility. These involved...
Six infant human teeth and 112 animal tooth pendants from Borsuka Cave were identified as the oldest burial in Poland. However, uncertainties around dating association of to have precluded their with an Upper Palaeolithic archaeological industry. Using <67 mg per tooth, we combined genetic analyses two six herbivore address these questions. Our interdisciplinary approach yielded informative results despite limited sampling material, high levels degradation contamination. confirm origin...

Coral reef records related to past higher and/or rising sea levels provide an important baseline for developing projections regarding the response of modern coastal systems future sea-level rise. Sea-level rise at end current century is expected range between 5.5 and 10 mm. yr-1 on average, depending various scenarios of&#160; global warming [IPCC, 2019]. The Last Deglaciation (23 6 kyr B.P.) seen as a potential recent analogue environmental changes that Earth may face in near...
