The use of nitrous oxide whippets as a recreational drug: Hidden health risks.

containing metallic particles. This contamination was investigated using liquid chromatography-, gas chromatography- and inductively coupled plasma-mass spectrometry (ICP- MS) and optical emission spectrometry ...

Identification and characterization of inorganic food additives and pearlescent pigments in sprays for food decoration by STEM-EDX

products and domestic cooking to enhance the appearance of food. To obtain specific hues, inorganic food additives containing (nano)particles are mixed in varying concentrations, and pearlescent pigments ...

Release of silver and titanium from face masks traded for the general population.

present in masks advertised for antimicrobial properties; whereas titanium dioxide (TiO) particles were detected in all the face masks in at least one layer corroborating its widespread use in the textile ...

Silver-based biocides and titanium dioxide particles in face masks for general use. Final report of the TiO2Mask and AgMask COVID-19 projects.

Publication Type: Sci. report, recommendat°, guidance doc., directive, monograph Authors: Daniela Montalvo; Charlotte Wouters; Lisa Siciliani; Christiane Vleminckx; Erik Van Miert; Nadia Waegeneers; Joris Van Loco; Eveline Verleysen; Karlien Cheyns; Jan M ...

Application of silver-based biocides in face masks intended for general use requires regulatory control

control SARS-CoV-2 infection needs to be balanced against possible toxicity due to inhalation exposure. Direct measurement of silver (particle) release to estimate exposure is problematic. Therefore, this ...

Regulatory safety assessment of nanoparticles for the food chain in Europe

small particles (including nanoparticles) in products used in the food chain in the EU falls within the remit of the European Food Safety Authority (EFSA) and has been under thorough scientific ...

Sentinel-2 Satellite and Hysplit Model Show that Local Cereal Harvesting Substantially Contributes to Peak Alternaria Spore Concentrations

contribution of cereal harvesting to peak Alternaria spore concentrations. Daily Alternaria spores were collected using Hirst-type traps in 12 sites in Europe for the period 2016-2018. Hybrid Single-Particle ...

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 ...

Evaluation of the types, efficient use and health risks of application of silver-based biocides to provide antimicrobial properties to face masks applied during the Covid-19 crisis

distributed in the matrix of the fibers, (iii) Ag NP and large silver particles at the surface of, or close to cotton fibres in face masks containing polycationic polymers binding Ag+ ions, and (iv) a coating ...
