Finding F-0308

“Compared with burning a fresh moxa wool without local exhaust ventilation, the emissions decreased by 70% (from 27 ppm to 8 ppm) for CO2, 91% (from 2.8 ppm to 0.3 ppm) for CO, 79% (from 0.024 ppm to 0.005 ppm) for HCHO, and 41% (from 0.24 ppm to 0.14 ppm) for TVOCs when the local exhaust ventilation was used.”

Structure

Factor: Formaldehyde (CH₂O)
Intervention: Mechanical ventilation
Setting: hospital treatment room, TW
Study design: controlled burning tests of moxa wool in a hospital treatment room in Taiwan: emissions of CO2, CO, formaldehyde, TVOC, PM2.5 and PM10 measured without control, with local exhaust ventilation and with an air cleaner (class 4)
Effect: difference 79
Caveat: moxibustion (burning moxa wool) has no Vocabulary slug as a source
