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 ...
Methodology report- Food Consumption Survey
questionnaires and measurements, as well as the organisation of the fieldwork. The document presents the data management, sample characteristics and finishes with information on how the results are presented in ...
Policy implementation and recommended actions to create healthy food environments using the Healthy Food Environment Policy Index (Food-EPI): a comparative analysis in South Asia
and improvements in school nutrition standards to combat NCD s. INTERPRETATION: Urgent action is required to expand food policies beyond hygiene and food security measures. Comprehensive strategies ...
Please don't throw me in the briar patch! Empirical evidence on the role of instructional cues on eco-label usage in fish consumption decisions
emphasizing the inadequacy of standalone labels and the necessity for complementary measures. Furthermore, the mechanisms underlying how consumers process multi-coloured Front-of-Pack (FOP) labels remain ...
Development of novel analytical methods to trace small micro- and nanoplastics in food matrices
a diameter smaller 1 µm, called nanoplastics (NP s) that could be found in food matrices and environmental samples, by means of specific measurement techniques. Therefore, the aim of this work is to develop ...
Cost and greenhouse gas emissions of current, healthy, flexitarian and vegan diets in Aotearoa (New Zealand)
and vegan. Design: Modelling study. Setting: Aotearoa (New Zealand). Main outcome measures: The distribution of the cost and climate impact (kgCO2e/kg of food per fortnight) of 2 weekly current, healthy, vegan ...
