Finding F-0135

“In experiments performed in the bathroom with 10 min dwell time of quats, mean PM2.5 and TVOC levels increased by 22.2 ± 8.4 μg m−3 and 198 ± 84 ppbv, respectively.”

Structure

Source: Cleaning products
Factor: Particulate matter (PM₂.₅ and PM₁₀)
Setting: bathroom, CA
Study design: chamber-style measurement study of emissions during surface cleaning events in two laboratories, an office and a residential bathroom (room volumes 22 to 206 m3, air change rates 0.85 to 9.14 h-1) with four cleaning solutions: quaternary ammonium compounds, hydrogen peroxide, sodium hypochlorite and thymol (class 4)
Effect: difference 22.2
Averaging time: 10 min dwell time of the cleaner
Caveat: printed as ± 8.4 without naming the measure of spread
