Rapports de recherche scientifique

Plusieurs des changements physiologiques associés à la thermorégulation peuvent influencer la cinétique des substances chimiques dans le corps humain, comme la ventilation alvéolaire et la redistribution du débit sanguin aux organes. Si certaines mesures préventives peuvent permettre de protéger les travailleurs contre les effets directs de la chaleur, elles ne permettent toutefois pas d’empêcher les processus de thermorégulation de prendre place. Une exposition concomitante à la chaleur et aux substances chimiques volatiles peut donc entraîner des variations dans l’absorption par inhalation et dans la cinétique de ces substances, biaisant ainsi l’évaluation des données de biosurveillance.

Dans cette étude, l’influence de …

Leakage Versus Material Filtration In Barrier Facemask Efficiency, Ali Bahloul, Clothilde Brochot, Barbara Layne

Études primaires

The World Health Association and many governmental agencies recommend the wearing of facemasks by the general public to prevent the spread of COVID-19. It is believed that masks can significantly protect others and may offer some protection to the wearer. Although there are standards for FFRs, surgical masks, and recently for barrier face coverings, they all indicate the level of protection for the wearer. However, testing facial masks not at the point of inhalation, but at the source, the exhale, offers a new perspective on how to impede particle emissions. In this paper, the experimental results show that, although the …
