Finding F-1657

“It was found that the overall performance declined by 1% for every 10 μg/m3 increase in PM2.5 concentration.”

Wu et al. The Synergistic Effect of PM2.5 and CO2 Concentrations on Occupant Satisfaction and Work Productivity in a Meeting Room (2021). International journal of environmental research and public health. Page 1. CKB 8125

Structure

Factor: Particulate matter (PM₂.₅ and PM₁₀)
Outcome: Cognitive performance
Setting: exposure chamber (office-like)
Study design: chamber experiment on occupant satisfaction and productivity: fine particles and carbon dioxide set to different concentrations in a room and related to the occupants' rated satisfaction and to their measured task performance (class 4)
Effect: difference 1 per 10 µg/m3 %
Caveat: the study adds that productivity fell by 1.1% or more for every 10% increase in dissatisfaction with the air quality

A Finding records what one published document states, verbatim and with its page. It is not a conclusion of Coridum; see the Claims that build on it.
