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

investigated leaching experiments using artificial acid sweat as a method to evaluate the release of Ag-based biocides and TiO particles present in face masks. Leaching experiments were proposed as an ...

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

study optimized methodologies to characterize silver-based biocides directly in the face masks, by measuring their total silver content using ICP- MS and ICP- OES based methods, and by visualizing the ...

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

mainly addressed to researchers, laboratories, food inspection agencies and policy makers: a search engine and database for agrifood reference materials and official methods an application programming ...

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

By combining optimized sample preparation with method validation, a significant variation in the particle size and shape distributions, the crystallographic structure (rutile versus anatase), and the ...

Is aggregated synthetic amorphous silica toxicologically relevant?

to address the toxicological relevance of aggregates of different sizes. Results: We used a precipitated SAS dispersed by different methods, generating 4 ad-hoc suspensions with different aggregate ...

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. ...

A systematic evaluation of Flow Field Flow Fractionation and single-particle ICP-MS to obtain the size distribution of organo-mineral iron oxyhydroxide colloids.

study was set up to determine the size of environmentally relevant FeOx colloids with new methods, i.e. Flow Field Flow Fractionation (FlFFF- UV- ICP- MS) and single-particle ICP- MS / MS (sp- ICP- MS) ...

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

approach on the certified reference materials ERM- FD100 and ERM- FD304. The image analysis method was validated in an inter-laboratory study by 19 laboratories, which resulted in a within-laboratory ...
