Method development for analysis of nanoplastics in drinking water and milk using transmission electron microscopy (TEM)
energy-dispersive X-ray spectroscopy (STEM- EDX) allowed differentiating plastic particles from mineral contaminants on the grid by their elemental composition. The limit of detection, determined by the sample ...
Genetic relatedness of Staphylococcus aureus isolates within food outbreaks by single nucleotide polymorphisms.
this study, we propose a SNP cut-off by taking into account the mutation rate and the evolution time of this pathogen in food. Through in vitro microevolution, we determined the mutation rate of three S. ...
EBoD-FL. Guidelines for mapping the environmental burden of disease in Flanders, 2024
according to a coherent framework. To tackle this objective, the disease burden attributable to environmental stressors is estimated using comparative risk assessment (CRA). As this method determines the ...
Assessing particle count in electron microscopy measurements of nanomaterials to support regulatory guidance
for different particle size and shape measurands, mathematical relationships betweenparticle count and precision, and subsequently to determine the minimum particle count. Our resultsconfirm that the ...
What makes an epidemic a disaster: the future of epidemics within the EM-DAT International Disaster Database.
system, serves as a determinant of epidemic disasters. The experts favored deaths and confirmed cases as key indicators, alongside suggestions on refining EM- DAT ’s entry criteria and improving epidemic ...
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 ...
Antigenic changes in influenza A(H3N2) driven by genetic evolution: Insights from virological surveillance, EU/EEA, week 40/2023 to week 9/2024
A(H1)pdm09 and 10,174 (25%) were influenza A(H3). For 809 (20%) of the type B viruses, the lineage was determined; all were B/Victoria/2/87 lineage, and none were B/Yamagata/16/88 lineage. Genetic ...

Sheeppox virus genome sequences from the European outbreaks in Spain, Bulgaria, and Greece in 2022-2024.
whole-genome sequences (WGS s) were determined from samples collected during these outbreaks and analyzed in the context of all other published WGS s. Sheeppox virus strains can be divided in two, or possibly ...
