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

consumers. Direct measurement of release of Ag and TiO particles during normal wearing is problematic by the lack of methodology to test release and to quantify inhaled particles. Therefore in this study, we ...

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 ...

METROFOOD-RI: Pilot services with physical, remote and virtual access

Van Loco Source: Measurement: Sensors, Volume 18 (2021) Keywords: ESFRI Food safety and quality Metrology research infrastructure Abstract: METROFOOD- RI (www.metrofood.eu) is an ESFRI research ...

Agglomeration of titanium dioxide nanoparticles increases toxicological responses in vitro and in vivo

exposed to these suspensions for 24 h and endpoints such as cytotoxicity, total glutathione, epithelial barrier integrity, inflammatory mediators and DNA damage were measured. Large agglomerates of 17 nm ...

Physicochemical Characterization of the Pristine E171 Food Additive by Standardized and Validated Methods.

spectrometry (spICP- MS). The evaluation of selected sample preparation protocols allowed identifying and optimizing the critical factors that determine the measurement of the particle size distribution by TEM. ...

Estimation of the Uncertainties Related to the Measurement of the Size and Quantities of Individual Silver Nanoparticles in Confectionery.

sample preparation, analysis and data interpretation were unraveled. The expanded measurement uncertainty for AgNP sizing was calculated to be 16% in E174-containing food products and increased up to 23% ...

Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials.

Source: Materials (Basel), Volume 12, Issue 14 (2019) Abstract: An approach for the size measurement of particulate (nano)materials by transmission electron microscopy was evaluated. The approach combines ...
