Release of silver and titanium from face masks traded for the general population.
present in masks advertised for antimicrobial properties; whereas titanium dioxide (TiO) particles were detected in all the face masks in at least one layer corroborating its widespread use in the textile ...
METROFOOD-RI: Pilot services with physical, remote and virtual access
infrastructure, funded upon the EU H2020 METROFOOD- PP project for its Preparatory Phase, aiming to establish a new distributed European Research Infrastructure (RI) to promote scientific excellence and increase ...
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.
for use as a food colorant in the European Union. The application of E171 in food has become an issue of debate, since there are indications that it may alter the intestinal barrier. This work applied ...
Is aggregated synthetic amorphous silica toxicologically relevant?
far, it is indeed believed that large aggregates represent a weaker hazard compared to their nano counterpart. Thus, we assessed the impact of SAS aggregation on in vitro cytotoxicity/biological activity ...
A systematic evaluation of Flow Field Flow Fractionation and single-particle ICP-MS to obtain the size distribution of organo-mineral iron oxyhydroxide colloids.
FlFFF- UV- ICP- MS is recommended for environmental studies of colloidal FeOx since it has a wide size detection range, it fractionates in an environmentally relevant background (1 mM NHHCO) and it has ...
Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials.
standard operating procedures for specimen preparation, imaging, and image analysis, and it was evaluated on a series of certified reference materials and representative test materials with varying physical ...
Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials
preparation, imaging, and image analysis, and it was evaluated on a series of certified reference materials and representative test materials with varying physical properties, including particle size, shape, and ...
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
additional parameters related to its particle size distribution. Titanium dioxide which is used as a food additive E 171 in food undergoes no surface treatment and is not coated. It consists of anatase or ...
