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

characterization Risk Assessment Silver textile Abstract: Silver-based biocides are applied in face masks because of their antimicrobial properties. The added value of biocidal silver treatment of face masks to ...

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

a more refined risk evaluation. The amount of silver in the four masks that contain Ag0 NP, Ag+ ions, and/or non-nanoparticulate silver exceeded the AEL mask. Per case an in depth risk analysis needs to be ...

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

A toxicologically relevant definition of NM s is therefore not yet available, which affects not only the risk assessment process but also hinders the regulation of nano-products. In this study, we assessed the ...

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 ...
