Release of Nano-objects, their aggregates and agglomerates from Masks (RENAAME): validation of a screening method to identify Ti and Ag elements in masks
LNE in partnership with INRS and SCIENSANO (Belgian public laboratory) is to develop a recognized and validated testing methodology for identifying the presence of nanomaterials declared or involved in ...
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 ...
Identification and characterization of TiO2 nanoparticles in face masks by TEM
textile ultramicrotomy Abstract: Because of the possible health risks related to the use of nanoparticle technologies in face masks, a general methodology is developed for identification, localization and ...
IDENTIFICATION, PHYSICOCHEMICAL CHARACTERISATION AND PRELIMINARY RISK ANALYSIS OF TITANIUM DIOXIDE PARTICLES IN FACE MASKS Intermediate report TiO2-Mask COVID-19 project September 2021
approach may overestimate the health risks because of the conservative inhalation exposure assumptions. However, for some face masks the amount of titanium dioxide is so high that a health risk cannot be ...
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
the influence of nanoparticle (NP) agglomeration and aggregation on toxicity is poorly understood although it is strongly believed that smaller the size of the NP s greater the toxicity. ...
Physicochemical Characterization of the Pristine E171 Food Additive by Standardized and Validated Methods.
Nanomaterials (Basel), Volume 10, Issue 3 (2020) Keywords: E171 food additive Single particle ICP-MS transmission electron microscopy Abstract: E171 (titanium dioxide) is a food additive that has been authorized ...
Is aggregated synthetic amorphous silica toxicologically relevant?
significantly relevant from a nanotoxicological perspective.This knowledge gap greatly afects the safety assessment and regulation of NM s, such as synthetic amorphous silica (SAS). SAS is used in a large panel ...
Estimation of the Uncertainties Related to the Measurement of the Size and Quantities of Individual Silver Nanoparticles in Confectionery.
Single particle ICP-MS Abstract: E174 (silver) is a food additive that may contain silver nanoparticles (AgNP). Validated methods are needed to size and quantify these particles in a regulatory context. ...
