Detailed Investigation of the Contribution of Gas-Phase Air Contaminants to Exposure Risk during Indoor Activities
While the AQI focuses on air pollutants such as O3 & NOx, our work suggests that organic compounds like acrolein may be more relevant.

A new study provides more evidence that non-smokers can be exposed to toxic amounts of chemicals lingering in indoor environments where smoking has occurred, a phenomenon called #ThirdhandSmoke.

NEW Let’s talk about transmission of respiratory infectious diseases
From Dr. @marinavance and Dr. @ShellyMBoulder@IndoorChem
To minimize long range aerosol transmission:
-Ventilation & Air Cleaning
-Wear a mask
-Reduce number of people indoors

What is dust made of? @sciencefocus
2/3 of the dust in your house comes from outside, as dirt tracked in on your feet & airborne particles like pollen & soot. The rest is mostly carpet fluff, clothes fibers and pet hair.

14/ Adding one more to the thread above about focused efforts to stay safest in #school this fall (#masks, #HEPA, #LunchOutside).
This is a fantastic infographic from @marwa_zaatari following inspiration from @Poppendieck & a dash of quotes from above.
2/ Aerosols v.s. Droplets - Size matters!
Aerosols (< 100μm) can sustain in the air for a longer period of time, travel a longer distance under the effects of airflow and ventilation, and penetrate more deeply into the lungs.

1/ School kids are highly vulnerable for Delta variant infection. To deliver some of the key points of airborne transmission to the general public, including school children, we've made a series of comics based on the Review we just published

Some interesting home-testing of #masks by @masknerd; reports all data here:

Testing methods a bit different than standard, so don't read into specific values.
Video e.g. for some kids/small #N95 masks tested. (ht @sueblackberry)

Real-world test of ionization in a campus building. We did not see a reduction in particle number concentrations at supply vent when system was on vs. off, measured using TSI Aerotrak. /1
