Release of silver and titanium from face masks traded for the general population.
ICPMS Nanoparticle Risk Assessment Silver textile Abstract: Previous assessments of a selection of face masks intended for the general population in Belgium found that silver (Ag)-based biocides were ...
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 ...

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 ...
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 ...
Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials.
study included an assessment of the limit of detection, working range, selectivity, precision, trueness, robustness, and ruggedness. An uncertainty that was associated to intermediate precision in the ...
Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials
agglomeration state. The measurement of the median value of the minimal external particle diameter distribution was intra-laboratory validated. The validation study included an assessment of the limit of ...
Scientific opinion on the proposed amendment of the EU specifications for titanium dioxide (E 171) with respect to the inclusion of additional parameters related to its particle size distribution
opinion deals with the assessment of the data provided by interested business operators in support of an amendment of the EU specifications for titanium dioxide (E 171) with respect to the inclusion of ...
Combining TEM with single particle ICP-MS: assessing the size of individual nanoparticles in food additives by multiple techniques
Publication Type: Scientific poster, presentation or proceeding Authors: Nadia Waegeneers; Delfosse,L.; Sandra De Vos; Eveline Verleysen; Jan Mast Source: Workshop: Physicochemical characterisation of nano-sized particles in food, Sciensano, Issue Sciensa ...
