Analyse von Bioziden/Pestiziden in Humanproben GerES V/VI Teil Pyrethroide, Glyphosat und AMPA

Ziel des Vorhabens ist es, die in GerES VI gewonnenen Morgenurinproben der Erwachsenen bzw. die vorhandenen Rückstellproben der Kinder und Jugendlichen aus GerES V auf Schadstoffe zu analysieren, die eine besondere Gesundheitsrelevanz aufweisen, wie bspw. die Gruppe der Biozide/Pestizide. In GerES IV (ehemals Kinder-Umwelt-Survey, KUS) wurden letztmalig Morgenurine von 3- bis 14-Jährigen auf Organophosphate und Pyrethroide untersucht. Jedoch gibt es für zahlreiche Pestizide keine aktuellen, repräsentativen Daten zur korporalen Belastung der Bevölkerung in Deutschland. Daher wird momentan die mögliche Belastung über Berechnungen basierend auf dem Lebensmittelverzehr und Belastungsdaten der verzehrten Lebensmittel geschätzt. Um diese Datenlücke zu schließen, wurden Biozide/Pestizide als priorisierte Substanzgruppe im Rahmen des Projekts HBM4EU erkannt. Zur Festlegung des Analytspektrums wurde im Rahmen von HBM4EU eine Auswertung zu deutschen und europäischen Anwendungsdaten der Pestizide/Biozide und eine Auswertung der in Europa vorhandenen Expositionsdaten durchgeführt. Zusammen mit den Ergebnissen der Befragung der teilnehmenden Personen liefern die Analysen der Morgenurine repräsentative Informationen zur Belastung der in Deutschland lebenden Bevölkerung.

Geochemistry and petrology of black opal in the pegmatites from Volyn (Ukraine)

Black opal is a rare variety of opal-CT, which is pigmented by organic matter (OM) and can therefore be considered as an example of geo-bio interaction (Gouzy et al., 2025). The locality of Volyn, Ukraine with its famous chamber pegmatites is well-known for interaction between OM and igneous rocks (Franz et al., 2017). The locality was recently renamed Khoroshiv, but because in the geological-mineralogical literature the name Volyn was introduced, we use this name here. The intrusion of the pegmatites is closely connected to the intrusion of the host rocks, granites of the southwestern part of the Korosten Pluton, and the intrusion age was determined as 1.76 Ga (Shumlyanskyy et al., 2021). OM was identified as kerite (fossilized remains of organisms; Franz et al., 2023, and references therein), and in fluid inclusions in beryl and topaz (Vozniak et al., 2012; Vozniak and Pavlyshin, 2008). Furthermore, formation of NH4-bearing feldspar (buddingtonite) and muscovite (tobelite) in breccia (identified together with the pegmatites) point to the interaction between decayed OM and the igneous minerals (Franz et al., 2017). The timing of the interaction between OM and igneous (and other) fluids is an important question (Franz et al., 2024), and therefore we also give age constraints on the formation of the black opal, which from textural arguments seems to be one of the latest mineral formations. We give detailed information about the sample sites, the macroscopic features of the samples of different types of opal, and the analytical procedures. The description of the black opal samples is presented in images from secondary electron microscopy (SEM), back-scattered electron images (BSE) obtained with by electron microprobe (EMPA), element distribution maps obtained by µXRF (X-ray fluorescence), Fourier-transformed infrared spectroscopy (IR), and X-ray powder (XRD) characterization. Chemical analyses were obtained by wave-length dispersive (WDS) analyses with the EMPA as well as by energy-dispersive (EDX) analyses with both the SEM and the EMPA instruments, to identify and characterize inclusions in the black opal. Trioctahedral Li-mica (polylithionite) is included by opal in one sample, and because this type of mica has not been described in detail from the Volyn peg-matites, we present the EMPA analytical data here in detail. The presence of OM, which is known to absorb U in sufficient amounts, allows dating by the U-Pb decay system. The results of the isotopic dating with the laser-ablation sector-field inductively-coupled mass spectroscopy system (LA-SF-ICP-MS) is presented for the selected individual do-mains in three samples. The operating conditions are summarized in a separated pdf document.

Global dataset for combined mineral major and trace element data for rocks from the lower oceanic crust

This work presents a Global dataset for combined mineral major and trace element data for rocks from the lower oceanic crust sampled along mid-ocean ridges worldwide. The dataset compiles mineralogical and geochemical data obtained from samples recovered along mid-ocean ridges characterized by a wide range of spreading rates, from fast-spreading to ultra-slow spreading ridges. It integrates published data from the scientific literature concerning the main mafic minerals of the lower oceanic crust, particularly olivine, plagioclase, and clinopyroxene, together with geological and geographical information related to the analysed samples. For each sample, the dataset includes details such as sampling location, oceanographic cruise, bibliographic reference, geographic coordinates, spreading rate, and sample lithology. The different worksheets contain average major element compositions and, where available, trace element data measured on crystal cores and rims. The dataset includes concentrations of major oxides, petrological parameters such as Fo# and Mg#, as well as trace element and rare earth element concentrations. The dataset was developed as a supporting tool for petrological, geochemical, and geodynamic studies aimed at improving the understanding of magmatic processes and the evolution of the lower oceanic crust along oceanic spreading centres.

Colombian emeralds – internal and external growth and dissolution features

Emeralds from Colombia are among the most highly-prized and valuable gemstones. Their growth phenomena including information about the geology of the area were described in detail by Pig-natelli et al. (2015, 2022) and Schmetzer and Martayan (2023). Here, we present data obtained by scanning electron microscopy (SEM), electron microprobe analysis (EMPA), and infrared absorption spectroscopy (IR) for five emerald crystals. The surface of the crystals shows both, growth phe-nomena as well as dissolution phenomena, the latter as etch pits (EP). Such EP have been used previously for other beryl types, mainly from pegmatitic environments (Kurumathoor and Franz, 2018); the Colombian emeralds come from low-grade metamorphosed black shales and thus offer the possibility to extend the use of EP as a provenance indicator to other types of beryl deposits. Internal structures are manifested in chemical zoning, investigated by EMPA and micro-X-ray fluo-rescence (µXRF). The crystals are characterized chemically by EMPA, polarized IR spectroscopy of oriented crystals showed the presence of fluids in the channels of the beryl structure.

High-resolution quantitative electron microprobe analysis of garnets from Holsnøy, Norway

The island of Holsnøy is located in southwestern Norway. It is composed of metastable granulite facies lower crust that was subducted at 430 Ma when fluid infiltrated the region and reacted with large portions of the area to form eclogite facies shear zones. The eclogite facies assemblages contain garnet with granulite facies cores and eclogite facies fractures and rims. This dataset contains quantitative electron microprobe transects from garnets from four different eclogite facies samples. They are divided into two groups: rim profiles that run from the garnet rims toward the cores, and fracture profiles that run perpendicular to eclogite facies fractures. Some profiles have 5–10 µm spacing and were collected at 15 kV accelerating voltage whereas others have 1 µm spacing and were collected at 10 kV which reduced analytical convolution and facilitated higher spatial resolution of the profiles.

Radiogenic isotope compositions of eruption products from the 2019 paroxysmal eruptions at Stromboli Volcano

The periodic volcanic activity of Stromboli Volcano, Aeolian Islands, Italy, is interrupted by paroxysmal eruptions on a decadal interval. In 2019, two strong paroxysms on July 3rd and August 28th, ended a more than a decade long period of regular strombolian activity. During normal strombolian activity the volcano erupts highly porphyritic scoria and lava (HP) with a shoshonitic basalt composition. In paroxysmal eruptions the HP material is mingled with low porphyritic (LP) pumices. This dataset includes the first radiogenic isotope data on the bulk compositions of the LP and HP components erupted on July 3rd 2019, and a HP sample from the lava flow that followed the paroxysm, and a LP sample from the paroxysm on August 28th 2019. The analyzed radiogenic isotope ratios include Sr, Nd, Hf, and Pb. This dataset further includes in-situ EPMA and LA-ICP_MS measurements of major and trace elements in the glass, olivine, plagioclase and clinopyroxene phases.

Mineral chemistry of chromite, orthopyroxene and plagioclase of chromitite layers in the Lower and Middle Group of the northwestern Bushveld Complex

This data set contains mineral chemical analyses of chromite, orthopyroxene and plagioclase of five chromitite layers and their immediate host rocks from drill core ZK135 of the northwestern Bushveld Complex. The sampled interval of ZK135 covers the transition of the Lower and Middle Group chromitites (LG6, LG6a, MG1, MG2, MG2 II). Detailed geochemical profiles are presented by data sheets and graphically to reveal small-scale variations in mineral chemistry. Mineral chemical analyses were conducted on drill core material from borehole ZK135 from the Thaba mine, operated by Cronimet Chrome Mining SA (Pty) Ltd. Briefly, each layer is hosted in pyroxenite and comprises a main chromitite layer and in some chromitites additional stringers above or below the main layer. Chromitites are composed of chromite, which are cemented by intercumulus plagioclase and orthopyroxene oikocrysts. A detailed study of the orthopyroxene oikocrysts in MG1 was published by Kaufmann et al. (2018). Additionally, euhedral to subhedral cumulus orthopyroxene is present in the LG6a, MG1 and MG2 layers. Pyroxenitic partings, small layers of pyroxenite within the chromitite, occur throughout the LG6 to MG2 layers. The main mineral phases chromite, orthopyroxene and plagioclase were analyzed by electron microprobe in each layer and the adjacent pyroxenitic host rocks. Major-element compositions of chromite, orthopyroxene and plagioclase were analyzed by electron microprobe at the Museum für Naturkunde Berlin with a JEOL JXA-8500F EMP equipped with a field emission cathode and five wavelength-dispersive spectrometers.
