Structure
- Factor
- Ozone (O₃)
- Population
- users and staff of health clubs
- Setting
- health club, PT
- Study design
- measurement campaign in eight health clubs in Porto, Portugal, under the occupancy and ventilation restrictions of the pandemic period: particulate matter as PM10 and PM2.5, particle number concentration between 20 and 1000 nanometres, total volatile organic compounds, carbon dioxide, ozone, temperature and relative humidity measured during occupied periods in the cardiofitness and bodybuilding areas and in the group class studios (class 4)
- Effect
- median 49.0
- Caveat
- the clubs had no photocopier, printer or air purifier running during the monitoring, so the study attributes the ozone to outdoor air coming in
