TY - JOUR A1 - Kittner, Maria A1 - Kalbe, Ute A1 - Altmann, Korinna T1 - Freisetzung von Mikroplastik aus Sportböden N2 - Die Europäische Kommission hat 2023 ein Verbot zum bewussten Austrag von Mikroplastik (MP) in die Umwelt beschlossen, das auch für die Verwendung von synthetischen Gummi-Granulaten (v. a. EPDM) in Sportböden gilt. In Deutschland gibt es laut DFB ca. 5100 Kunstrasenplätze. In der EU beläuft sich die Anzahl laut ECHA auf 13,000 Kunstrasen- und 47,000 Bolzplätze, Tendenz steigend. Das Hauptziel des Projektes ist daher, eine Massenbilanz für die Freisetzung von MP zu erstellen, um so eine Schätzung des MP-Austrags pro Kunstrasenplatz und Jahr zu ermöglichen. Dafür werden die MP-Emissionen von drei Kunstrasenszenarien in verschiedenen Zuständen (ungealtert, künstlich gealtert und in Echtzeit gealtert) verglichen: die Vergangenheit (Kunstrasen: fossilbasiert, EPDM-Füllung), die Gegenwart (der in Europa am häufigsten installierte Rasen) und die Zukunft (Rasen mit recycelten Grasfasern, keine synthetische Füllung sondern z.B. Quarzsand oder Korkschrott). Dazu werden fabrikneue Kunststoffrasen und EPDM-Granulat unter Laborbedingungen beschleunigt gealtert, um die Freiland-Beanspruchung eines Kunststoffrasens in circa 15 Jahren abzubilden. Die Verwendung spezieller Mikrofiltertiegel in Lysimeter-Experimenten ermöglicht die Abschätzung der Partikelgrößen des emittierten MP, was eine Grundbedingung für die Bewertung einer potenziellen Gesundheitsgefährdung für Menschen ist. Ergänzend werden weitere umweltrelevante Schadstoffausträge aus den Kunststoffrasen quantifiziert und so mögliche Transportpfade überprüft. Um in Zukunft den Anforderungen des Kreislaufwirtschaftsgesetzes zu entsprechen, sollen in diesem Projekt zudem Erkenntnisse zur Rückführbarkeit von Gummi-Granulaten und Altrasen in den Rohstoffkreislauf gewonnen werden KW - Mikroplastik KW - TED-GC/MS KW - Kunststoffrasen KW - PAK KW - Schwermetalle PY - 2024 UR - https://www.zukunftbau.de/neue-meldung/zukunft-bau-journal-2024 SP - 9 EP - 9 PB - Bundesinstitut für Bau-, Stadt- und Raumforschung (BBSR) CY - Bonn AN - OPUS4-61823 LA - deu AD - Bundesanstalt fuer Materialforschung und -pruefung (BAM), Berlin, Germany ER - TY - CONF A1 - Altmann, Korinna T1 - Detektion von Mikroplastik N2 - In dem Vortrag geht es um die Möglichkeiten der Detektion von Mikroplastik im Allgemeinen.

T1 - Inflammation-related key events stimulated by micro- and nanoplastics N2 - The presence of micro- and nanoplastic particles (MNP) in our environment has raised increasing public and political concern. Increasing evidence suggests that humans are exposed to these MNP, mostly via inhalation or ingestion. The EC-Horizon project POLYRISK (https://polyrisk.science) aims to establish an IATA/AOP-based tiered approach to assess human health risks of MNP. In our research, we focus on assessing immunotoxicological effects of MNP. We have tested a series of primary, secondary, environmentally aged (incubated in River Rine water) and chemically altered MNP for their potential to affect dendritic cells or macrophages. MNP used in this study include primary and weathered PS, secondary PVC, PA, PP (with or without talc) and PE. The secondary PE and PP (w/o talc) particles appeared to have oxidized groups on their surface. Data shows that MNP can be engulfed by macrophages (PMA-stimulated human THP1 cells) and human blood-derived dendritic cells (DCs). The effects of virgin as well as secondary MNP (0, 10 or 100 μg/ml) on THP1 macrophages were limited to decrease of mitochondrial activity (Alamar blue), increase of cellular leakage (LDH), and stimulation of lysosomal activity. None of these MNP stimulated gene expression of NFκB or release of pro-inflammatory cytokines (IL-6, TNFα, IL-1β). On the other hand, secondary PP and PE with oxidized surface groups did increase NFκB gene expression and release of cytokines by THP1 macrophages. Virgin and weathered PS particles were tested using DCs, and only weathered PS did stimulate DC activity (increased costimulatory molecules CD83, CD86) and as consequence allogeneic T cells. DC activation appeared to result from environmental contaminants. In conclusion, of all MNPs tested only those that contained active surface groups or environmental components appeared to be immunostimulatory, whereas primary and secondary MNP rather reduced macrophage activity and viability (at relatively high concentrations of 100 μg/ml). Further research is needed to reveal molecular mechanisms and to translate in vitro findings to real-world exposure scenarios.

T1 - Exposure protocol for ecotoxicity testing of microplastics and nanoplastics N2 - Despite the increasing concern about the harmful effects of micro- and nanoplastics (MNPs), there are no harmonized guidelines or protocols yet available for MNP ecotoxicity testing. Current ecotoxicity studies often use commercial spherical particles as models for MNPs, but in nature, MNPs occur in variable shapes, sizes and chemical compositions. Moreover, protocols developed for chemicals that dissolve or form stable dispersions are currently used for assessing the ecotoxicity of MNPs. Plastic particles, however, do not dissolve and also show dynamic behavior in the exposure medium, depending on, for example, MNP physicochemical properties and the medium’s conditions such as pH and ionic strength. Here we describe an exposure protocol that considers the particle-specific properties of MNPs and their dynamic behavior in exposure systems. Procedure 1 describes the top-down production of more realistic MNPs as representative of MNPs in nature and particle characterization (e.g., using thermal extraction desorption-gas chromatography/mass spectrometry). Then, we describe exposure system development for short- and long-term toxicity tests for soil (Procedure 2) and aquatic (Procedure 3) organisms. Procedures 2 and 3 explain how to modify existing ecotoxicity guidelines for chemicals to target testing MNPs in selected exposure systems. We show some examples that were used to develop the protocol to test, for example, MNP toxicity in marine rotifers, freshwater mussels, daphnids and earthworms. The present protocol takes between 24 h and 2 months, depending on the test of interest and can be applied by students, academics, environmental risk assessors and industries.

T1 - Requirements for inter-lab comparison studies and cooperation with CUSP and JRC N2 - Results from different methods applied to micro- and nanoplastics (MNPs) analysis show that there are large gaps in harmonisation with respect to terminology, size classes, sample preparation protocols and, finally, to the comparability of the measurands and descriptors. Within the European research cluster to understand the health impacts of micro- and nanoplastics (CUSP) working group WG3-Inter-Laboratory Comparisons an overview of the existing detection methods revealing advantages and disadvantages regarding the analytical tasks is being compiled. There is a clear need to develop high class characterized reference materials for MNPs in the size ranges of 100-10 µm and smaller than 10 µm, so that these can be used to validate methods and to make results comparable. Inter-laboratory comparisons (ILCs) on model samples with complex matrices regarding mass, or water samples for number-based methods, will help us to advance the process of harmonization as well as to train users early in process of developing new methods. We plan to keep all five CUSP projects well-connected also with the 'outside' MNP projects and ILCs and to extract the optimum of needs, capabilities, and efforts in order to launch new VAMAS ILCs which should expand already available ones.

The ultra-thin ESI layers (2–30 nm) of commercial poly(acrylic acid) and poly-(hydroxyethylmethacrylate) produce an significant increase of adhesion measured by single-fiber pull out tests. However, plasma Treatment has also advantages, such as simultaneous activation of the fiber substrate.

Microplastic may harm desalination facilities by blocking filters and disturbing the marine food chain. Thermo analytical methods such as pyrolysis gas chromatography mass spectroscopy, and spectroscopic methods like (micro) Raman spectroscopy or (micro) Fouriertransform infrared spectroscopy in combination with appropriate filters and sample preparation are suitable for analyzing microplastics on a scale from 1 µm to 1000 µm fast and unambiguous. While the thermo analytical methods are suitable for larger sample volumes, Raman spectroscopy and Fouriertransform infrared spectroscopy are able to detect and analyze single microplastic particles for instance in bottled water. Machine learning algorithms ensure a reliable classification of different plastic materials.

Dabei wird häufig von einer großen Anzahl an MP-Partikeln in allen Bereichen der Umwelt, wie dem Wasser, dem Boden, der Luft und in Biota sowie über mögliche Gefahren ausgehend von MP, berichtet. Jedoch sind diese Studien häufig nicht untereinander vergleichbar, da verschiedene Konzepte der Probennahme, der Aufbereitung und unterschiedliche Detektionsverfahren verwendet werden. Um diesen Mangel an vergleichbaren und aussagekräftigen Daten zu beheben, wird aktuell versucht, eine Harmonisierung der Mikroplastikanalytik voranzutreiben. Neue, schnellere Methoden zur MP Quantifizierung wurden entwickelt. Gleichzeitig werden neue Strategien zur Probenahme und Probenvorbereitung konzipiert, da hier die Fehlerquellen besonders große Auswirkungen auf das Ergebnis haben. In diesem Vortrag werden verschiedene Verfahren bezogen auf Probennahme, -vorbereitung und Analytik gezeigt und bezüglich ihres möglichen Ergebnisses diskutiert. T2 - 7.
