Finding F-1246

“In all HCs, TVOCs (0.01–39.67 mg/m3) highly exceeded the existent protection thresholds (1.6–8.9 times) due to the frequent use of cleaning products and disinfectants (2–28 times higher than in previous works).”

Structure

Factor: Total volatile organic compounds (TVOC)
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: mean 39.67
Caveat: the study attributes the levels to the frequent use of cleaning products and disinfectants under the pandemic rules
