IDENTIFICATION, PHYSICOCHEMICAL CHARACTERISATION AND PRELIMINARY RISK ANALYSIS OF TITANIUM DIOXIDE PARTICLES IN FACE MASKS Intermediate report TiO2-Mask COVID-19 project September 2021
presence of agglomerated TiO2 (nano)particles in all examined face masks that contain polyester or polyamide (nylon) fibres, or that are made of non-woven, synthetic fabrics. These particles resemble ...
A Targeted UHPLC-MS/MS Method Validated for the Quantification of Ergot Alkaloids in Cereal-Based Baby Food from the Belgian Market
one ergot alkaloid was detected with 2 samples containing 12 ergot alkaloids. Ergometrine was the alkaloid most frequently detected i.e., 16 out of 49 samples. Only one sample, testing positive for all ...
Development of vibrational spectroscopic methods combined with chemometrics for the detection and quantification of nicotine in e-liquids.
nicotine-containing e-liquids via the internet. The ban on long-distance sale implies that postal packages containing e-liquids are checked at customs. Furthermore, there is a demand of vapeshop-inspectors for on-site ...
Development of a real-time PCR marker targeting a new unauthorized genetically modified microorganism producing protease identified by DNA walking
DNA walking analysis was performed on a protease product suspected to contain a new unauthorized genetically modified microorganism (GMM). Though the characterization of unnatural associations of ...
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.
moderately contaminated samples. Our results clearly indicate that 21% of the seed spices and 25% seed-based aromatic mixes contain an amount higher than 400 μg of the 30 summed targeted PA s and PANO s per ...
Selection and use of reference panels: a case study highlighting current gaps in the materials available for foot and mouth disease.
controls for new point-of-care test formats that can be deployed outside high containment, harmonise FMDV antigens for post-vaccination serology, and address inter-laboratory differences in serological ...
Towards Real-Time and Affordable Strain-Level Metagenomics-Based Foodborne Outbreak Investigations Using Oxford Nanopore Sequencing Technologies
Technologies, and we compared this to Illumina short-read-based metagenomics. After 12 h of MinION sequencing, strain-level characterization could be achieved, linking the food containing a pathogen to the ...
4DEMON: Integrating 40 Years of Data on PCB and Metal Contamination in Marine Sediments of the Belgian Part of the North Sea
long-term models revealed decreasing trends for most metals, except zinc (Zn) for which three out of four models showed increasing concentrations in all five zones of the BPNS. Offshore sediments contained ...
The occurrence of non-anatomical therapeutic chemical-international nonproprietary name molecules in suspected illegal or illegally traded health products in Europe: A retrospective and prospective study.
over a defined period of time. This paper reports the results of the most recent study in this context with the focus on health products containing non-Anatomical Therapeutic Chemical-International ...
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.
cardiovascular Dietary Supplements Abstract: BACKGROUND: Weight loss and sports supplements containing deterenol have been associated with serious adverse events including cardiac arrest. OBJECTIVE: To determine ...
