Leakage Versus Material Filtration In Barrier Facemask Efficiency, Ali Bahloul, Clothilde Brochot, Barbara Layne Jan 2021

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 …

Rapports de recherche scientifique

Plusieurs manipulations réalisées sur les corps des défunts par les thanatopracteurs produisent des bioaérosols qui peuvent contenir des agents pathogènes infectieux. La ventilation générale est souvent le seul moyen utilisé dans les laboratoires de thanatopraxie pour maîtriser les bioaérosols. Toutefois, il n’y a pas de recommandations précises pour sa mise en application. De plus, peu d'études abordent les expositions professionnelles aux bioaérosols dans le domaine de la thanatopraxie tant quantitativement (niveau d’exposition) que qualitativement (identification et classification selon les groupes de risque). L’objectif de cette étude était d’évaluer l’exposition des thanatopracteurs aux bioaérosols afin d’apprécier les risques potentiels sur leur …


The Assessment Of Co2 Exposures, Workload Demands, And Musculoskeletal Disorder Risk On Heart Rate For Select Craft Brewery Job Tasks, David L. Huizen Aug 2020

The Assessment Of Co2 Exposures, Workload Demands, And Musculoskeletal Disorder Risk On Heart Rate For Select Craft Brewery Job Tasks, David L. Huizen

Dissertations

Americans have embraced craft beer, and the ensuing demand has resulted in an ever-increasing number of craft breweries opening over the past 20 years. Craft brewers are generally small employers and, as such, lack the resources necessary to address the safety and health of their employees adequately. Brewers face many safety and health hazards in their work environment. These hazards include exposures to carbon dioxide (CO2), workload demand, and MSD risk. It is essential to evaluate these hazards in craft breweries as they handle carbon dioxide (CO2) differently than large breweries by having the CO2 …

Performance Of Mechanical Filters Used In General Ventilation Against Nanoparticles, Clothilde Brochot, Pooya Abdolghader, Fariborz Haghighat, Ali Bahloul

Études primaires

With an equal mass, nanoparticles (NP) have a higher toxicity than particles with the same chemical composition but with larger surface area. However, the toxicological knowledge concerning NP is still insufficient to establish limit values of exposure. To seek the lowest exposure level, filtration is a simple and effective way to capture particles, including NP. According to ANSI/ASHRAE 52.2 standard, ventilation filters efficiency is tested for particles ranging from 0.3 to 10.0 μm. Performances of entire filters for NP are still very limited and particle size of 300 nm (0.3 μm) is commonly used as the most penetrating particle size …

Aneuploidy: A Common And Early Evidence-Based Biomarker For Carcinogens And Reproductive Toxicants., Daniele Mandrioli, Fiorella Belpoggi, Ellen K Silbergeld, Melissa J. Perry

Environmental and Occupational Health Faculty Publications

Aneuploidy, defined as structural and numerical aberrations of chromosomes, continues to draw attention as an informative effect biomarker for carcinogens and male reproductive toxicants. It has been well documented that aneuploidy is a hallmark of cancer. Aneuploidies in oocytes and spermatozoa contribute to infertility, pregnancy loss and a number of congenital abnormalities, and sperm aneuploidy is associated with testicular cancer. It is striking that several carcinogens induce aneuploidy in somatic cells, and also adversely affect the chromosome compliment of germ cells. In this paper we review 1) the contributions of aneuploidy to cancer, infertility, and developmental abnormalities; 2) techniques for …
