Development of novel analytical methods to trace small micro- and nanoplastics in food matrices

particular, samples containing NP s have been separated by hydrodynamic diameter with AF4, then analyzed by MADLS to characterize their size and size distribution. Finally, the polymer type of the NP s has been ...

Occurrence of microcystin congeners in surface waters and food in Belgium as a source of exposure to humans

analyzed, whereof nine samples contained MC s. Moreover, three samples exceeded the concentration of 1 µg g−1 total microcystins, previously proposed as a guideline value. Microcystis sp. were determined as ...

Implementation of MALDI-TOF Mass Spectrometry to Identify Fungi From the Indoor Environment as an Added Value to the Classical Morphology-Based Identification Tool

available in an in-house created reference database containing over 1,700 strains from the BCCM / IHEM fungal collection. Results: A total of 149 isolates including 18 yeasts and 131 filamentous fungi were ...

Development of strain-level shotgun metagenomics approaches to detect and characterize microbiological contaminants in the context of food safety

Enteritidis strain linked to the outbreak could be obtained, fully characterized, and related to the food and human isolates from the outbreak in a phylogenetic tree containing other Belgian sporadic cases and ...

Evaluation of the types, efficient use and health risks of application of silver-based biocides to provide antimicrobial properties to face masks applied during the Covid-19 crisis

distributed in the matrix of the fibers, (iii) Ag NP and large silver particles at the surface of, or close to cotton fibres in face masks containing polycationic polymers binding Ag+ ions, and (iv) a coating ...

Acid digestion of nonwoven textiles for measuring their trace element content by ICP techniques

elastane-containing textiles resulting in a complete release of metallic contents in order to analyze their elemental contents by ICP  techniques. Health Topics:  Nanomaterialen Nanomatériaux Nanomaterials Service:  ...

Development, Validation and Application of a Targeted LC-MS Method for Quantification of Microcystins and Nodularin: Towards a Better Characterization of Drinking Water

related hepatoxins are the microcystin congeners (MC s) and nodularin (NOD) (Figure 1). Both contain in their structure an (2S,3S,8S,9S)-3-amino-9-methoxy-2,6,8-trimethyl-10-phenyl-4,6-decadienoic acid ...

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 ...

Opinion: Airtightness for Decontamination by Fumigation of High-Containment Laboratories

high-containment Hydrogen Peroxide Abstract: Introduction: While the European legislation states that laboratories of high-containment must be sealable for fumigation, they do not prescribe a minimal value for ...
