Release of silver and titanium from face masks traded for the general population.
acceptable exposure limit values derived from inhalation exposure limits indicate that three face masks would need further risk assessment and could not be considered as intrinsically safe. Health Topics: ...
Application of silver-based biocides in face masks intended for general use requires regulatory control
control SARS-CoV-2 infection needs to be balanced against possible toxicity due to inhalation exposure. Direct measurement of silver (particle) release to estimate exposure is problematic. Therefore, this ...
IDENTIFICATION, PHYSICOCHEMICAL CHARACTERISATION AND PRELIMINARY RISK ANALYSIS OF TITANIUM DIOXIDE PARTICLES IN FACE MASKS Intermediate report TiO2-Mask COVID-19 project September 2021
approach may overestimate the health risks because of the conservative inhalation exposure assumptions. However, for some face masks the amount of titanium dioxide is so high that a health risk cannot be ...

Genotoxic evaluation of the liquids present in electronic cigarettes
device that vaporizes liquid for inhalation by the user. In general, the e-cigarette is perceived as being healthier than the conventional cigarette because no combustion process (and subsequently no ...
Oxidative stress pathways involved in cytotoxicity and genotoxicity of titanium dioxide (TiO2) nanoparticles on cells constitutive of alveolo-capillary barrier in vitro.
The health risks of nanoparticles remain a serious concern given their prevalence from industrial and domestic use. The primary route of titanium dioxide nanoparticle exposure is inhalation. The extent ...
Occurrence of polybrominated diphenyl ethers and emerging halogenated flame retardants in food items
environment. The main exposure of the population to BFR s is via the diet, inhalation of indoor air and ingestion of indoor dust. In particular, the lack of data on the occurrence of BFR s in food prevents an ...
