Fluorescent biological aerosol particles in residence

Residences represent an important site for bioaerosol exposure because of the large proportion of time that people spend in their homes. Using real-time instrumentation, our recent study in Indoor Air investigated bioaerosol concentrations, emissions, and exposures in a northern California residence, focusing on the effect of human occupancy and activities. Using an ultraviolet aerodynamic particle …

This air resistance is a real drag: global survey of antibiotic resistance genes in air samples

This new open access paper from Li et al may be of interest. Global Survey of Antibiotic Resistance Genes in Air.   Abstract: Despite its emerging significant public health concern, the presence of antibiotic resistance genes (ARGs) in urban air has not received significant attention. Here, we profiled relative abundances (as a fraction, normalized by 16S rRNA …

Radio Joe Reports – Sloan Research to Practice Kickoff & IAQA #IAQ

Just got pointed to this by Paula Olsiewski.  “IAQ Radio” with Radio Joe.   Looks like they have a number of interviews with people in the field including Jordan Peccia, Mark Hernandez, Tiina Reponen, and more.   Episode #492 is a recent report of the IAQA Annual Meeting and the Sloan-funded “Roadmap Research to Practice”.  Worth checking …

Yes, gross, but interesting: Human skin flakes lead to bad smell in air-conditioning systems 

OK so this is based on a press release so it should be taken with a grain of salt and such.  But it is interesting, and gross too, and about microbiology of the built environment. Skin squames contribute to ammonia and volatile fatty acid production from bacteria colonizing in air-cooling units with odor complaints Source: …
