    “…[Figure: see text] [Figure: see text] METHODS: We developed culture and culture-independent (real-time PCR, reference to standard curve) methods for measuring airborne fungal burdens using SAS Super 100 and SASS 3100 Dry Air samplers. We performed serial surveillance in 7 units with high-risk, immunosuppressed patients in 2 hospitals and outside. …”

    “…They explored microbiological (bacterial and fungal) and blood (visible and/or imperceptible) contamination at the person level (patients, operators and assistants) and/or at a wider environmental level, using settle plates, chemiluminescence reagents or air samplers; all within 1 m of the surgical site. Studies were of generally low to medium quality and highlighted an overall risk of contaminated aerosol, droplet and splatter generation during oral surgery procedures, most notably during removal of impacted teeth using rotatory handpieces. …”

    “…We measured 24 or 48-h personal exposures and kitchen and ambient concentrations of fine particulate matter (PM2.5) using gravimetric samplers. RESULTS: In the cross-sectional analysis, median (interquartile range, IQR) kitchen PM2.5 concentrations in biomass and LPG using homes were 134 μg/m3 [IQR:71–258] and 27 μg/m3 [IQR:20–47], while corresponding personal exposures were 75 μg/m3 [IQR:55–104] and 36 μg/m3 [IQR:26–46], respectively. …”

    “…A mobile behavior lab was used to quantify behaviors of steers that were associated with generation of PM(2.5) (e.g., fighting, mounting of peers, and increased locomotion). PM(2.5) samplers measured respirable particles with a mass median diameter ≤2.5 μm (PM(2.5)) every 15 min over a period of 7 d in April and May. …”
