The textile industry is potentially a major contributor, releasing synthetic particles like polyamide, polyester, and acrylic during production. This study assessed MNP levels outside and inside a textile-processing facility using online air samplers with silicon (Si) and quartz filters. Real-time particle counts (PM0.3–PM10) were obtained via a laser detector. Si filters (9 mm, 10/1 µm pores) and quartz filters (25 mm, 1.2 µm pores, pre-calcined at 800°C) were used for sampling. Custom holders allowed selective sampling for PM10 and PM1 on Si filters. Sampling conditions included a 3-hour collection at 2 L/min (GilAir Plus pump) starting at 7:00 AM (T1) and 2:00 PM (T2), with intermittent ventilation, 23.3 °C average temperature, and 52.5% humidity. Particle weights collected (µg) were: quartz – 4.9E-05 (T1), 5.1E-05 (T2); Si – 3.2E-05 (T1), 5E-06 (T2). Outside particle counts ranged from 3,584 (T1) to 15,165 (T2); inside: 9,901 (T1) to 12,921 (T2). Maximum indoor PM10 and PM0.3 levels were 72/m³ and 71,979/m³, respectively. Particles were analyzed using electron microscopy and µRaman spectroscopy, confirming high concentrations of irregularly shaped PP-based particles (1–5 µm).

Therefore, the fate of fluorine during incineration was investigated in a full-scale hazardous waste incinerator to assess the viability and potential risks of this method. The project involves developing advanced analytical tools, including real-time infrared spectroscopy, and conducting trial burns under varied conditions. Conditions that influence incineration performance are identified, analyzing for products of incomplete destruction (PIDs), exploring the role of fly ash and surfaces in PFAS breakdown, and evaluating the potential formation of polyfluorinated dioxins and furans. Collectively, these tasks aim to deliver practical tools and guidance for scientists and engineers, while informing policymakers and the public on the benefits and potential risks of PFAS incineration.

It is a liquid chromatographic technique that separates molecules based on their size, respectively their hydrodynamic volume using a porous stationary phase that allows smaller molecules to pass through the pores while excluding larger molecules. The chromatogram from the size separation can be calibrated using polymers of known molar mass resulting in a relative molar mass distribution curve. From this distribution curve molar mass averages and the oligomer content (percentage of peak area smaller than 1000 g/mol and 500 g/mol) of polymers can be derived. The determination of oligomer content is important, because it is often used in regulatory contexts as a measure of small, mobile and potentially more toxic parts of the polymer. Polymer regulations are of increasing political and societal importance. Regulations often strive for narrow limits. But SEC has rather large error margins of 10-20% for the molar mass determination performed in different laboratories or on different instruments. These variances are well known to all experts and users and have been investigated in several round robin tests in the past. These resulted in DIN and ISO standards which, in our opinion, no longer meet today's requirements. Gaps have been identified that require further harmonization. Different polymer types or classes require different methods. On the other hand, as far as we know, the margins of error in determining oligomer content have not yet been investigated. It is expected that the variation will be rather high. This is because it depends on many factors related to the experimental conditions (column sets used, solvent, temperatures, sample preparation) on the one hand, and the data evaluation mechanisms (choice of baseline and peak limits) on the other. In order to actually measure the error margins and to support this with actual data a round robin test has been performed from June to November 2024 with approx. 40 participating laboratories. Three different solvents were selected, namely THF, DMAc or DMF and water. The samples were selected taking into account a wide range of practical aspects far from narrowly distributed standards: e.g higher distribution range, reduced solubility, included side components, copolymers and dispersions with gel content. In this contribution we will present the detailed concept of this round robin test and first impressions.

Their slow compact growth, and thick melanized cell walls confer exceptional stress tolerance but have long hindered molecular studies and genetic engineering. Consequently, the biology and biotechnological potential of these organisms remained largely unexplored. To overcome these limitations, we selected the rock-inhabiting black fungus Knufia petricola as a model. Its genome sequence (12 contigs, ~10,000 genes) enabled the development of a versatile genetic toolbox based on CRISPR/Cas9-mediated editing, achieving up to 100% homologous recombination and supporting multiplex editing of at least six genomic regions. Color-based selection systems targeting pigment genes enable rapid identification of strains with correctly integrated expression cassettes, including simultaneous insertion of optimized genes coding for blue, green, and red fluorescent proteins for co-localization and protein interaction studies. These tools enable functional analyses of traits central to extremotolerance, such as the role of melanin in stress protection, biofilm formation, and material interactions. Furthermore, K. petricola has been established as a eukaryotic expression platform: heterologous genes from bacteria, fungi, and plants can be expressed under constitutive or inducible promoters, including the Tet-on system for tunable gene regulation. Pigment-free strains provide access to metabolic precursors, enabling high-level synthesis of alternative secondary metabolites. Importantly, the optimized transformation protocols were successfully transferred to the Antarctic black fungus Cryomyces antarcticus, a cryptoendolithic extremophile and astrobiology model, demonstrating that even the most stress-tolerant fungi can be genetically engineered. Together, the genome sequence and advanced genetic engineering strategies have transformed K. petricola from a challenging extremotolerant organism into a tractable model for studying stress adaptation, material interactions and a promising host for biotechnology and synthetic biology approaches. These achievements, combined with emerging black fungal genomes, inform sustainable material protection strategies to mitigate colonization and biodeterioration of exposed surfaces, linking fundamental research with applied solutions for material conservation and industrial biotechnology.
