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, ...
Advancing automated identification of airborne fungal spores: Guidelines for cultivation and reference dataset creation
monitoring. While manual methods exist, interest is shifting towards automated systems employing machine learning. However, challenges persist due to diverse particle properties and limited training data. This ...
A validation methodology for size and shape measurement of nanoplastics by transmission electron microscopy
surface. Each series of 10 images is analyzed using the ParticleSizer software in ImageJ. The intermediate precision of the quantitative TEM measurement is evaluated using a top-down approach [4] combining ...
Characterization of functional nanoparticles applied in face masks by STEM-EDX
development regarding the assessment of inhalation exposure to nanoparticles during mask use. To assess the potential of particle release and associated risks, at first a detailed characterization of the ...
Advancing automated identification of airborne fungal spores: Guidelines for cultivation and reference dataset creation
real-time monitoring. Most of them rely on machine learning for the identification of bioparticles. However, the diverse nature of airborne particles in terms of size, properties and composition presents ...
NATIONAL SURVEILLANCE OF SARS-COV-2 IN WASTEWATER- How does WBE contribute to the global epidemiologic assessment in Belgium? (September 2020 – 2024)
circulation in a population, since people infected by COVID-19 excrete particles of SARS-CoV-2 in wastewater. The circulation of SARS-CoV-2 in the Belgian population is monitored since September 2020 by taking ...
The use of nitrous oxide whippets as a recreational drug: Hidden health risks.
containing metallic particles. This contamination was investigated using liquid chromatography-, gas chromatography- and inductively coupled plasma-mass spectrometry (ICP- MS) and optical emission spectrometry ...
Airborne DNA: State of the art – Established methods and missing pieces in the molecular genetic detection of airborne microorganisms, viruses and plant particles
Publication Type: Peer reviewed scientific article Authors: Pogner, C.-E.; Antunes, C.; Apangu, G.P.; Nicolas Bruffaerts; Celenk, S.; Cristofori, A.; González Roldán, N.; Grinn-Gofroń, A.; Lara, B.; M. Lika; Magyar, D.; M. Martinez-Bracero; Muggia, L.; Mu ...
Identification and characterization of inorganic food additives and pearlescent pigments in sprays for food decoration by STEM-EDX
products and domestic cooking to enhance the appearance of food. To obtain specific hues, inorganic food additives containing (nano)particles are mixed in varying concentrations, and pearlescent pigments ...
EFSA Project on the use of New Approach Methodologies (NAMs) for the hazard assessment of nanofibres. Lot 1, nanocellulose oral exposure: gastrointestinal digestion, nanofibres uptake and local effects
indications for genotoxicity were obtained. Finally, no formation of smaller particles following colonic fermentation of NC was observed. For the integration of these results in regulatory hazard assessment of ...
