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 ...

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: ...
