Structure
- Factor
- Carbon dioxide (CO₂)
- Outcome
- Cognitive performance
- Population
- college students
- Setting
- test chamber, CN
- Study design
- controlled chamber exposure experiment with college students in Chongqing: 4-hour exposures to 500 ppm and 2500 ppm pure CO2 with and without added negative air ions, cognitive test battery and symptom questionnaires (class 3)
- Effect
- difference -13.57
- Caveat
- pure CO2 added to the chamber, not metabolic CO2; the same study tested negative air ions (no Vocabulary slug yet)
