Urine concentrations of Arsenic and its species in adolescents from Wallonia (Belgium).

had detectable concentrations of AsT. The geometric mean urine concentrations for adolescents were 8.1 μg/L for AsT, 2.7 μg/L for AB, and 3.7 μg/L for TRA. Since fish or seafood are a major arsenic ...

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

(NP s), mainly originating by physico-chemical transformation processes, such as aging, degradation and fragmentation. Because of the ease in their detection, several studies have been conducted on ...

Dietary exposure of Sorbates (E 200 – 202) and Benzoates (E 210 – 213) for the Belgian population

these FA s was estimated. Three matrix-matched analytical methods were developed using ion chromatography coupled with conductivity detection. The methods were validated in-house and applied to 387 ...

Strain-level characterization without culture enrichment? Easing and accelerating outbreak investigation using shotgun metagenomics facilitated with nanopore adaptive sampling

samples during an outbreak investigation requires the samples to be enriched in order to reach detectable levels. However, a bias can occur during the enrichment of the food due to competition between the ...

Multidimensional chromatographic fingerprinting combined with chemometrics for the identification of regulated plants in suspicious plant food supplements

channels for their purchase. Therefore, some of these products may be ‘suspicious’ and a risk for consumers health.   This study aims at developing a screening approach for detection of four regulated plants ...

Pyrogen testing of phage therapeutic products

cell wall, flagellin, etc. are not detected by those tests. As phages are being produced in a growing variety of bacterial host strains, including gram-positive bacteria, an expansion of the QC workflow ...

Validation of an animal-free analytical method for the detection of bacterial endotoxins in human vaccines

Publication Type: Scientific poster, presentation or proceeding Authors: Flore Laurent; Laure Cuignet; Julien Lamme; Hanae Kachach; Zahra Boukhouchi; Geneviève Waeterloos Source: NA, VUB- Symposium 3R (2023) Keywords: Endotoxin " vaccine &quo ...

COMBINATION OF CHEMOMETRICS AND MULTIDIMENSIONAL FINGERPRINTING FOR DETECTION OF REGULATED PLANTS IN PLANT FOOD SUPPLEMENTS

concerns, necessitating an efficient screening approach for detection of the regulated plants in plant food supplements.   This study aims at developing a chemometric approach coupled with fingerprinting for ...
