The purity of tattoo inks, screening substances of high concern
±20% Results: The methodology was applied to 86 samples of which 26 are violating the current Resolution ResAP (2008). 5-nitro toluidine was found in 16 samples, all of them having an unacceptable health ...
4DEMON: Integrating 40 Years of Data on PCB and Metal Contamination in Marine Sediments of the Belgian Part of the North Sea
polychlorinated biphenyls (PCB s) and metals in the Belgian Part of the North Sea (BPNS). Multiple challenges were encountered: sampling locations changed over time, different analytical methods were applied, ...

Ecotoxicity profile of heavily contaminated surface water of two rivers in Tunisia
approaches. In the physicochemical analysis, the recorded levels of COD and TSS in both samples exceed the Tunisian standards. Using the analytical approach, several metals and some textile dyes were detected. ...
Use of Whole Genome Sequencing Data for a First in Silico Specificity Evaluation of the RT-qPCR Assays Used for SARS-CoV-2 Detection.
started in December 2019. COVID-19 cases are confirmed by the detection of SARS-CoV-2 RNA in biological samples by RT-qPCR. However, limited numbers of SARS-CoV-2 genomes were available when the first ...
Environmental exposures and health behavior in association with mental health: a study design.
ideation, subjective health and depressive and anxiety disorders, demographics and health behavior such as smoking are derived from the BHIS. Urine and blood samples are collected to measure respectively the ...
Assessment of natural coagulants to remediate Tunisian textile wastewater by combining physicochemical, analytical, and toxicological data
coagulation-flocculation using biocoagulants derived from cactus Opuntia ficus indica and eggplant Solanum melongena to remove toxic compounds from Tunisian textile wastewater samples was evaluated by combining assays to ...
Migration of mineral oil from cardboard packaging for food: Identification of the hazards and assessment of the exposure of the Belgian population
The detected MOSH and MOAH concentrations were then compared to the action thresholds set by the Scientific Committee (SciCom) of the Belgian Food Safety Agency (FASFC) in 2017. Only one sample exceeded ...
Nanomaterials for food applications: Analytical challenges and practical solutions for enforcing labeling of nanoingredients in food products in the European Union
“nano” labeling poses several analytical challenges. This includes the many potential sources of NP s in food which can interfere with the analysis, the challenges in relation to sample preparation, the ...
Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography- tandem mass spectrometry
BPB, BPF, and BPS) and two alkylphenols (nonyl phenol (NP) and tert-octylphenol (OP) in human placenta samples. After a short sample preparation time the extracts are analysed by UHPLC- MS / MS using ...
