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
of NC exist, i.e. bacterial NC (BNC), nanofibrillated cellulose (NFC), and cellulose nanocrystals (CNC). The biological sources and processing conditions affect several physicochemical parameters of ...
Application of silver-based biocides in face masks intended for general use requires regulatory control
Christiane Vleminckx; Joris Van Loco; Eveline Verleysen Source: Science of The Total Environment, Volume 870 (2023) Keywords: Ag Biocide electron microscopy Face masks ICPMS Nanoparticle Physicochemical ...
Regulatory safety assessment of nanoparticles for the food chain in Europe
Keywords: Integrated approaches to testing and assessment (IATA) nanomaterial particulate material Physicochemical characterisation Risk Assessment Toxicity testing Abstract: Background The risk assessment of ...
Advances in the physicochemical characterization of nanoparticles in a regulatory context.
specifying, registering and labelling, as well as characterizing particulate (nano)materials for risk assessment, require measurement of the physicochemical properties of their constituent particles. Because of ...
Development, validation and application of multi-class methods for the analysis of food additives by liquid chromatography coupled to tandem mass spectrometry
Food additives are used in numerous food products and are characterised by various physicochemical properties. In European member states, their use in food is regulated by the European Union. This work ...
EFSA guidance on technical requirements for regulated food and feed product applications to establish the presence of small particles including nanoparticles
dissolution rate as key physicochemical properties to assess whether consumers will be exposed to particles. The second group establishes the information requirements for assessing whether the conventional ...
Detection of toxins involved in foodborne diseases caused by Gram‐positive bacteria
the relevant properties of these toxins. Advanced research has led into new insights of the incidence of toxins, mechanisms of their production, their physicochemical properties, and their toxicological ...
Assessment of natural coagulants to remediate Tunisian textile wastewater by combining physicochemical, analytical, and toxicological data
Environmental Science and Pollution Research, Volume 27, Issue 32 (2020) Keywords: Analytical chemistry Bioassays Biocoagulants Physicochemical properties Textile effluents Abstract: Due to the complexity and ...
Prioritizing substances of genotoxic concern for in-depth safety evaluation using non-animal approaches: The example of food contact materials.
of these are furthermore listed as a Substance of Very High Concern (SVHC) by the European Chemicals Agency (ECHA), in addition to demonstrating physicochemical properties linked to a high migration ...
Printed paper and board food contact materials as a potential source of food contamination.
(77%) considered non-evaluated in terms of potential toxicity. Based on a preliminary study of their physicochemical properties, it is estimated that most of the non-evaluated single substances have the ...
