A validation methodology for size and shape measurement of nanoplastics by transmission electron microscopy
is lacking, however, we assume it corresponds to the mean ECD of the material. The values and expanded uncertainties we obtained for the mean ECD are 51±4 nm, 198±7 nm and 518±13 nm, for the three ...
Characterization of functional nanoparticles applied in face masks by STEM-EDX
health effects are reported for nano-silver [3], their use in masks raises health concerns because of the potential inhalation exposure to nanoparticles. This emerging area of concern lacks methodological ...
Occurrence of microcystin congeners in surface waters and food in Belgium as a source of exposure to humans
cyanotoxins in food, drinking and recreational water are available in Belgium. Among the main reasons for this data shortage is a lack of publicly sourced, reliable methods to analyze cyanotoxins in food and ...
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 ...
Residential Exposure to Urban Trees and Medication Sales for Mood Disorders and Cardiovascular Disease in Brussels, Belgium: An Ecological Study
because the assessment of exposure to trees is often imprecise because of, for instance, exclusion of trees in private areas and the lack of three-dimensional (3D) exposure indicators (e.g., crown volume). ...
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 ...
Taxonomic annotation of public fungal ITS sequences from the built environment- A report from an April 10-11, 2017 workshop (Aberdeen, UK)
sequence databases. In addition, the sequence metadata required to make informed taxonomic decisions – such as country and host/substrate of collection – are often lacking even from reference and ex-type ...
Scientific Statement on Presence of microplastics and nanoplastics in food, with particular focus on seafood
toxicokinetic data are lacking for both microplastics and nanoplastics for a human risk assessment. It is recommended that analytical methods should be further developed for microplastics and developed for ...
Systematic identification of hypothetical bacteriophage proteins targeting key protein complexes of pseudomonas aeruginosa
Abstract: Addressing the functionality of predicted genes remains an enormous challenge in the postgenomic era. A prime example of genes lacking functional assignments are the poorly conserved, early ...
Scientific opinion on emerging and novel brominated flame retardants (BFRs) in food
widely for these BFR s. There is a lack of experimental data on physico-chemical characteristics, stability/reactivity and current use and production volume of all the emerging and novel BFR s. Due to the ...
