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 ...
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 ...

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 ...
Spectroscopic approaches for conformity analysis of e-liquids
classify samples according to nicotine and present additives. So, their presence in new suspected samples could be detected. In a second step, PLS regression was applied to estimate the nicotine ...
