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 ...
EFSA Project on the use of New Approach Methodologies (NAMs) for the hazard assessment of nanofibres. Lot 1, nanocellulose oral exposure: gastrointestinal digestion, nanofibres uptake and local effects
(iii) assessment of any digestion or degradation of NC by the human microbiome. Eight NC samples belonging to the three NC types, plus a comparator in the micro-range, were selected as study materials and ...
Development of strain-level shotgun metagenomics approaches to detect and characterize microbiological contaminants in the context of food safety
contaminant present in the sample at once, possibly also at the SNP level. At the time this study started, shotgun metagenomics for the study of food contaminants was in its infancy. Moreover, strain-level ...
Comparison of 6 DNA extraction methods for isolation of high yield of high molecular weight DNA suitable for shotgun metagenomics Nanopore sequencing to detect bacteriaAbstractBackgroundResultsConclusion
level, were specifically designed for this application and need to be assessed. Results: In this study, with different bacterial cocktail mixes, analyzed as pure or spiked in a synthetic fecal matrix, we ...
Simultaneous Detection and Quantification of Aflatoxin M1, Eight Microcystin Congeners and Nodularin in Dairy Milk by LC-MS/MS
188½006. Unfortunately, there is a notable lack of data concerning the transfer of various emerging microbial contaminants into dairy milk and, therefore, their natural occurrences. In this study, a simple ...
Development, Validation and Application of a Targeted LC-MS Method for Quantification of Microcystins and Nodularin: Towards a Better Characterization of Drinking Water
meteorological factors and their prediction is still under study [9,10,11,12]. The presence of these blooms can have a detrimental effect on the water quality by producing compounds that lead to foul tastes and ...
Nanomaterials for food applications: Analytical challenges and practical solutions for enforcing labeling of nanoingredients in food products in the European Union
limitations of existing analytical techniques, and the lack of validated studies and reference materials. This book chapter summarizes these challenges and, in addition, suggests a screening strategy for ...
Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography- tandem mass spectrometry
1121, Number 102 (2019) Keywords: Alkylphenol Bisphenol endocrine disruptor Paraben Placenta UHPLC-MS/MS Abstract: This study presents de development and validation of an ultra- high performance liquid ...
Comparison of SNP-based subtyping workflows for bacterial isolates using WGS data, applied to Salmonella enterica serotype Typhimurium and serotype 1,4,[5],12:i:.
presented in this study illustrate the importance of using correct data analysis strategies and to define benchmark and fine-tune parameters applied within routine data analysis pipelines to obtain ...
Biological activity conferred by endocrine disrupting chemicals in hospital effluent and river water from the Brussels Region, Belgium
routinely monitored in targeted chemo-analytical methods and can detect them at low amounts (pg/L EEQ, Estrogen EQ uivalence). The bioassay used in this study is the CALUX (Chemically activated luciferase ...
