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

alternative method to evaluate the quality of face masks, and as a higher tier method to assess face masks that are not safe-by-design. Results from leaching experiments showed that Ag was released in amounts ...

Acid digestion of nonwoven textiles for measuring their trace element content by ICP techniques

elastane-containing textiles resulting in a complete release of metallic contents in order to analyze their elemental contents by ICP  techniques. Health Topics:  Nanomaterialen Nanomatériaux Nanomaterials Service:  ...

IDENTIFICATION, PHYSICOCHEMICAL CHARACTERISATION AND PRELIMINARY RISK ANALYSIS OF TITANIUM DIOXIDE PARTICLES IN FACE MASKS Intermediate report TiO2-Mask COVID-19 project September 2021

excluded even when only a small fraction of the titanium dioxide particles are released and inhaled. Currently, we have no indications that TiO2 particles are released in amounts which might result in public ...

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

influence of NP agglomeration on their toxicity/biological responses in vitro and in vivo. Results: We tested two TiO2 NP s with different primary sizes (17 and 117 nm) and prepared ad-hoc suspensions ...

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

physicochemical form (pearlescent pigments versus anatase and rutile E171) was demonstrated among the representative samples. These results are important for risk assessment of the E171 food additive and can ...

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 ...

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 ...
