Release of silver and titanium from face masks traded for the general population.
present in masks advertised for antimicrobial properties; whereas titanium dioxide (TiO) particles were detected in all the face masks in at least one layer corroborating its widespread use in the textile ...
The analysis of cannabinoids in e-cigarette liquids using LC-HRAM-MS and LC-UV.
alleged therapeutic benefits, a low potential for abuse and lack of the typical psychoactive effects associated with the use of cannabis products containing high levels of ∆9-tetrahydrocannabinol (∆9- THC). ...

potential for abuse and lack of the typical psychoactive effects associated with the use of cannabis products containing high levels of ∆9-tetrahydrocannabinol (∆9- THC). In Belgium, CBD-containing e-liquids ...
Application of silver-based biocides in face masks intended for general use requires regulatory control
type(s) and localization of silver-based biocides using electron microscopy based methods. Thirteen of 20 selected masks intended for general use contained detectable amounts of silver ranging from 3 μg to ...
The healthiness of New Zealand school food environments: a national survey.
schools were invited to complete a cross-sectional questionnaire. School nutrition policies were analysed using an adapted Wellness School Assessment Tool. Canteen menus were analysed using the National ...
Listeria monocytogenes isolates from Cornu aspersum snails: Whole genome-based characterization and host-pathogen interactions in a snail infection model.
Here, we use whole-genome sequencing (WGS) to assess the genomic diversity of hypervirulent, virulent and non-virulent phenotypes of 15 L. monocytogenes isolated from snails to unveil their survival, ...
Targeted LC-MS/MS combined with multilocus DNA metabarcoding as a combinatory approach to determine the amount and the source of pyrrolizidine alkaloids contamination in popular cooking herbs, seeds, spices and leafy vegetables.
contained DNA from. Taken together, it can be stated that the proposed combinatory chemical and molecular techniques could be used to verify if a PA / PANO (s) contamination occurred in these popular cooking ...
4DEMON: Integrating 40 Years of Data on PCB and Metal Contamination in Marine Sediments of the Belgian Part of the North Sea
different grain size fractions were analyzed, appropriate co-factors were not always analyzed, and measurement uncertainties were not always indicated. These issues hampered the use of readily available, ...
Nine prohibited stimulants found in sports and weight loss supplements: deterenol, phenpromethamine, oxilofrine, octodrine, beta-methylphenylethylamine, 1,3-dimethylamylamine, 1,4-dimethylamylamine, 1,3-dimethylbutylamine (1,3-DMBA) and higenamine.
two containers or subsamples of the same brand, both products were reanalyzed by Sciensano (Brussels, Belgium). NSF International carried out qualitative and quantitative analyses using ...
