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 ...
Implementation of METROFOOD services in the Belgium node
Forum on Research Infrastructures) research infrastructure (RI), METROFOOD- RI, an European distributed- RI aimed at promoting scientific excellence via high-level metrological services in food and ...
Assessing particle count in electron microscopy measurements of nanomaterials to support regulatory guidance
minimum particle count generally depends on the width of the size and shapedistributions and that the median of the distribution can be determined with the highest precisioncompared to other percentiles. ...
Particle size analysis of iron hydroxide adipate tartrate (IHAT) in a food supplement: Interlaboratory testing of a dynamic light scattering method
constituent particle size, referred to in the implementing regulation as ‘primary particle size’. In this study, a method to determine the constituent particle size distribution of IHAT using the volume-based ...
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, ...
Reflections of the NRL: implementation of EN ISO 11133 in food microbiology laboratories
2 (published in 2020) describes the performance testing of confirmation media and reagents. EN ISO 11133:2014 applies to producers such as commercial bodies producing and/or distributing ready-to-use or ...
Identification and characterization of inorganic food additives and pearlescent pigments in sprays for food decoration by STEM-EDX
mixtures, characterisation of the fraction of small particles, including the particle size distribution, is needed for each single constituent or each component in the mixture2. This is challenging for ...
Development of novel analytical methods to trace small micro- and nanoplastics in food matrices
larger MP s in terms of occurrence, distribution, quantification, and toxicological effects on humans identifying food as their main intake source. Nowadays, research interest is going towards MP s with ...
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 ...
Aluminium intake through the consumption of selected baby foods and risk characterization in a population of Brazilian infants aged 0 to 36 months
In addition, distributions were fitted on the concentration and consumption data for further probabilistic intake estimations. The results corroborated well with the deterministic approach. The highest ...
