Reducing the particles generated by flushing institutional toilets
Autor: Changjie, Cai, Peter, Kim, Thomas H, Connor, Yingtao, Liu, Evan L, Floyd
Publikováno v: Journal of Occupational and Environmental Hygiene. 19:318-326
Airborne particles play a significant role in the transmission of SARS-CoV-2, the virus that causes COVID-19. A previous study reported that institutional flush-O-meter (FOM) toilets can generate 3-12 times as many droplets as other toilets by splash

The Effect of Flow Rate on a Third-Generation Sub-Ohm Tank Electronic Nicotine Delivery System—Comparison of CORESTA Flow Rates to More Realistic Flow Rates
Autor: Toluwanimi Oni, Sara Greenlee, Evan L. Floyd, Lurdes Queimado, Balaji Sadhasivam
Publikováno v: International Journal of Environmental Research and Public Health
International Journal of Environmental Research and Public Health, Vol 18, Iss 7535, p 7535 (2021)
Volume 18
Issue 14
Many types of electronic cigarettes (ECs) are currently in use, but the default flow rate used to simulate puffing is centered on tobacco cigarette flow rates. CORESTA offers several methods and technical guides for evaluation of ECs but there are fe

A comparison of air sampling methods for Clostridium difficile endospore aerosol
Autor: Kathleen A.N. Aithinne, Casey W. Cooper, David L. Johnson, Evan L. Floyd, Bradley S. Stevenson
Publikováno v: Aerobiologia. 35:411-420
The airborne dissemination of Clostridium difficile (C. difficile) endospores (spores) in healthcare environments is documented in multiple studies. Once airborne, spores have the potential for transport on air currents to other areas. This study com
