Optimization and validation of an analytical method for the quantification of short- and medium-chained chlorinated paraffins in food by gas chromatography-mass spectrometry
Reference Laboratory (EURL) interlaboratory study on CP s in food. The EURL ’s accuracy criteria was met for both homologue groups in all food matrices with overall accuracy in the range of 76–130% for ...
An expert opinion assessment of blood-feeding arthropods based on their capacity to transmit African swine fever virus in Metropolitan France.
and Occupational Health & Safety performed an expert knowledge elicitation. In total, 15 different BFA s were selected as potential vectors by the ad hoc working group involved. Ten criteria were ...
Use of a Whole Genome Sequencing-based approach for Mycobacterium tuberculosis surveillance in Europe in 2017-2019: an ECDC pilot study.
including both core genome multilocus sequence typing (cgMLST), and single nucleotide polymorphism (SNP)-based calculation of distances on all WGS data that fulfilled minimum quality criteria to ensure data ...
Identification of risk areas and practices for Taenia saginata taeniosis/cysticercosis in Ethiopia: a systematic review and meta-analysis.
criteria. The average zonal prevalence of meat inspection-based BCC ranged from 2% in Buno-Bedele to 24.6% in Sidama zone. The pooled prevalence of BCC was influenced by the number of muscle/organs inspected, ...
PT-2020-NRL-TE-FASFC “Determination of As, Cd, Pb and Hg in food supplements"
Estimation of a correct measurement uncertainty stays a difficult excersize: five of the calculated ζ-scores were unsatisfactory. Not all laboratories met the LOQ criteria for Hg [1]. No consensus value could ...
Bepaling van spoorelementen in diverse matrices met spectrometische technieken.
(garments) were mineralized with HNO3 + HF in a heating block and the Ti concentration was analyzed with an ICP- OES. The raw results were evaluated with the acceptance criteria and then reported. Results In ...
EFSA guidance on technical requirements for regulated food and feed product applications to establish the presence of small particles including nanoparticles
requirements for applications in the regulated food and feed product areas, and establishing criteria for assessing the presence of a fraction of small particles. These requirements apply to particles requiring ...
Towards a unified classification for human respiratory syncytial virus genotypes.
regarding the criteria that define HRSV genotypes and their nomenclature, challenging data comparisons between research groups. In this study, we aim to unify the field of HRSV genotype classification by ...
Confronting Risk of Bias in RF Bioeffects Research. Comments on Two Papers by Vijayalaxmi and Prihoda
improve the quality of RF bioeffects research. Vijayalaxmi and Prihoda applied four quality criteria to each article: 1. adequacy of exposure assessment; 2. blinded design; 3. use of positive controls; and ...
Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography-tandem mass spectrometry
methods using spiked samples at three concentration levels (0.5–5 and 25 ng g−1). The parameters accuracy and precision fulfill the criteria. Calibration curves are linear between 0.5 and 50 ng −1. The ...
