TY - CONF A1 - Bresch, Harald T1 - OECD TG 125 Particle size and size distribution of Nanomaterials N2 - This presentation was held in an OECD Webinar introducing the newly developed and published OECD TG 125 on particle size and size distribution. The presentation is explaining the structure if the TG 125 and addresses all included methods and methodologies in a short and understandable way for the broader public. The presentation includes sections about nano-particles and nano-fibres.

T1 - Trends in selected fields of reference material production N2 - For more than 110 years, BAM has been producing reference materials for a wide range of application fields. With the development of new analytical methods and new applications as well as continuously emerging more stringent requirements of laboratory accreditation with regard to quality control and metrological traceability, the demand and requirements for reference materials are increasing. This trend article gives an overview of general developments in the field of reference materials as well as developments in selected fields of application in which BAM is active. This includes inorganic and metal analysis, gas analysis, food and consumer products, and geological samples. In addition to these more traditional fields of application, developments in the areas of optical spectroscopy, particulary fluorescence methods, and nanomaterials are considered.

It further describes research activities at BAM concerning the characterization of nanoparticles and the way to the digital representation of these characterization possibilities. It concludes with the challenges of a digital product passport (DPP) for nanomaterial based products and the need of a digital materials passport (DMP). Finally, the activities of BAM are presented which address the former mentioned challenges from ESRP and DPP.

They were extensively examined for their toxicological effect in vitro and in vivo, but their effects on environmental and biological systems remain underexplored. A key area of concern is how nanoparticles interact with microbial communities in natural ecosystems, since these communities are vital for processes such as nutrient cycling, biodegradation, and maintaining ecosystem health and functioning. Currently, environmental risk assessments of nanoparticles majorly involve higher organisms (e.g. algae, zooplankton), but omit the effects on complex communities and ecosystems as a whole. This research aims to investigate the impact of nanomaterials on aquatic microbial communities using a combination of laboratory experiments and field-sampling along a gradient from low to highly anthropogenically impacted aquatic ecosystems around Berlin, Germany. To holistically assess changes in microbial composition and functional activity in response to nanomaterial exposure, we will apply molecular, microbiological, analytical as well as OMIC methods. We hypothesize that nanoparticles induce significant compositional changes in microbial community structures, potentially leading to alterations in stress responses and other functional effects. Nanomaterials have the potential to benefit the environment by contributing to energy and resource efficiency, remediation of contaminated sites, or water treatment. In order to represent truly sustainable products, though, a safe use for humans and ecosystems must be assured. Ultimately, this research will contribute to more accurate environmental risk assessments and help guide the responsible use of nanotechnology in various industries.
