Optimised dispersion protocol for particle size measurement of copper oxides applied as feed additives and plant protection products
commercially distributed as powders, and limited information on their particle size distribution is available. The EFSA Guidance on Particle-Technical Requirements requires measuring the particle size ...
Method development for analysis of nanoplastics in drinking water and milk using transmission electron microscopy (TEM)
addresses this by developing advanced methodologies for characterizing and measuring NP in food matrices, using transmission electron microscopy (TEM) to assess size and shape — critical parameters for ...
Patient-reported indicator surveys (PaRIS): Insights from Belgium
Sciensano, Brussels, p.101 (2025) Accession Number: D/2025.14.440/15 Keywords: chronic diseases international survey Patient reported experience measures (PREMs) Patient reported outcome measures (PROMs) ...
Assessing particle count in electron microscopy measurements of nanomaterials to support regulatory guidance
practicesfor measurements but lacks requirements on how many particles to measure. Using transmissionelectron microscopy data of nanomaterials, a strategy based on repeated subsampling is proposedto establish, ...
Bioaccumulation of organic and inorganic contaminants in biota: A long-term evaluation in the Belgian part of the North Sea
weight, dry weight, grain size, and total organic carbon were measured and used to understand the difference between the observed bioaccumulation and the measured sediment concentrations. Health Topics: ...

A validation methodology for size and shape measurement of nanoplastics by transmission electron microscopy
impacts. In this study, we establish a foundational framework for such measurements by validating a transmission electron microscopy (TEM)-based approach, in the context of the European project PlasticTrace ...
Characterization of functional nanoparticles applied in face masks by STEM-EDX
face masks. The method is evaluated in terms of ability to distinguish different nanoforms, to measure particle properties (size/shape/agglomeration state) important in the context of risk assessment in ...
Analyzing the airborne birch and grass pollen monitoring network in Belgium
life. Mitigation measures can alleviate pollen-induced symptoms, but these require early warning systems providing timely information on forthcoming pollen episodes. The performance of such systems can be ...
Estimating the Uncertainty in Airborne Birch Pollen Modelling
input data and ECMWF ERA5 meteorological data. The relative Coefficient of Variation (CV %) is used as a measure for uncertainty. The studied key model input datasets that drive the birch pollen ...
