Effects of tree pollen on throughfall element fluxes in European forests
found between TF nitrate-nitrogen (NO3 −-N) fluxes and SPI n. For Quercus and Pinus, two genera producing many flowers each year, SPI n displayed limited variability and no clear association with TF ...
Implementation of MALDI-TOF Mass Spectrometry to Identify Fungi From the Indoor Environment as an Added Value to the Classical Morphology-Based Identification Tool
molds is generally performed by microscopy. This method has, however, some limitations as it requires mycologists with high expertise while identification is often limited to the genus level. Therefore, ...
A Summer of Cyanobacterial Blooms in Belgian Waterbodies: Microcystin Quantification and Molecular Characterizations
sequencing. The cyanobacterial diversity for two water samples was characterized with amplicon sequencing. Microcystins were detected above limit of quantification (LOQ) in 68 water samples, and the World ...
Cost-effectiveness analysis of a school- and community-based intervention to promote a healthy lifestyle and prevent type 2 diabetes in vulnerable families across Europe: the Feel4Diabetes-study.
cost-effective, especially in countries with a high overweight and obesity prevalence, at a limited budget impact. The incremental financial investments to reach and support high-risk families did not result in the ...
In utero exposure to parabens and early childhood BMI z-scores – Associations between placental ethyl paraben, longitudinal BMI trajectories and cord blood metabolic biomarkers
annotated to GGT and longitudinal measurements of BMI z-scores were investigated with adjusted linear mixed models. Results: The geometric means of placental MeP, EtP, PrP, and BuP levels above the limit of ...
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 ...
A systematic evaluation of Flow Field Flow Fractionation and single-particle ICP-MS to obtain the size distribution of organo-mineral iron oxyhydroxide colloids.
detection limit for FeOx of about 32-47 nm. The distribution of hydrodynamic diameters of goethite particles detected with FlFFF, NTA and DLS were similar but the values were twice as large as the Fe cores of ...
Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials.
study included an assessment of the limit of detection, working range, selectivity, precision, trueness, robustness, and ruggedness. An uncertainty that was associated to intermediate precision in the ...
Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials
agglomeration state. The measurement of the median value of the minimal external particle diameter distribution was intra-laboratory validated. The validation study included an assessment of the limit of ...
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 ...
