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 ...
Migration of mineral oil from cardboard packaging for food: Identification of the hazards and assessment of the exposure of the Belgian population
a different toxicological profile, the two fractions were quantified separately using an online combination of liquid chromatography and gas chromatography with flame ionization detection (online LC- GC- FID). ...
Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography- tandem mass spectrometry
limits of detection and quantification are in the range of 0.1-0.3 ng g−1 and 0.2-0.7 ng g−1, respectively. The applicability of the method was demonstrated on 71 human placenta samples from a Belgian ...
Dermal exposure of Belgian florists to insecticide residues
insecticides were detected on flowers and 55 insecticides on cotton gloves. An average of 0.6 mg/kg insecticide residues per flower sample were measured. Acephate had the highest mean and maximum concentration ...

A survey of pesticide residues in cut flowers from various countries.
methods (GC- MS- MS and LC- MS- MS) in a laboratory accredited for pesticide residues. For all the samples analysed, a total of 97 active substances were detected, i.e. an average of 14 active substances ...
A molecular approach for the rapid, selective and sensitive detection of Exophiala jeanselmei in environmental samples: development and performance assessment of a real-time PCR assay
jeanselmei. In this study, we developed a SYBR ®green real-time PCR assay based on the internal transcribed spacer 2 from the 18S ribosomal DNA complex for the specific detection of E. jeanselmei. The ...
Toxicity in lead salt spiked soils to plants, invertebrates and microbial processes: Unraveling effects of acidification, salt stress and ageing reactions.
increase of total soil Pb dose required to induce 10% inhibition. The toxicity of Pb in leached soils was intermediate between the other two treatments. The lowest detectable chronic thresholds (EC10) in ...
