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 ...
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, ...
Particle size analysis of iron hydroxide adipate tartrate (IHAT) in a food supplement: Interlaboratory testing of a dynamic light scattering method
results demonstrate that dynamic light scattering can reliably measure the particle size of particles in the low nanometre range if samples are prepared and measured following a robust, easy-to-reproduce, ...
Physicochemical characterization and genotoxicity assessment of nanomaterials using new approach methodologies
additive [3]. A detailed physicochemical characterization of the test materials is an essential first step in the risk assessment. It includes measuring the particle size distribution, surface charge, ...
Per- and polyfluoroalkyl substances in food and beverages: determination by LC-HRMS and occurrence in products from the Belgian market.
analysis of 268 food products from the Belgian market demonstrated that 43% of samples contained at least one PFAS with a maximum of eleven PFAS measured in a stew of wild pork. PFOS was the most detected ...
