2. Methodology

2.1. IAQ assessment in 11 fitness centers
A monitoring program was undertaken in 11 fitness centers from Lisbon where comfort parameters (temperature and humidity) and indoor air pollutants (PM, CO2, CO, CH2O, VOC and O3) were measured. Fig. 1 shows the localization of the selected fitness centers and Table 1 presents their specific characteristics. Three direct reading apparatus were used: a Lighthouse Handled 3016 to measure PM5-10, PM2.5-5, PM1-2.5, PM0.5-1 and PM0.3-0.5, temperature and relative humidity, a WolfSense to assess CO2, CO, VOC and O3 and a Formaldemeter htV-M to quantify the levels of CH2O. All devices were calibrated according to the fabricators specifications. Measurements were performed during the period of the late afternoon/night, in order to overlap with the more occupied period and with the worst case scenario. In each fitness center, measurements took place in the bodybuilding room (Bb) for 60 min, and in two studios (S1 and S2), during the time of a fitness class (varied between 45 and 60 min). Equipment was positioned at an elevation of 1.20 m from the ground and 1.50 m away from walls in order to avoid the influence on airborne particle dispersion [32,33]. The same air pollutants described previously were measured in the outdoor air. The sampling campaign was performed in October of 2012.
