Sedentary subjects occupied an environmental chamber (20-22 deg C, 35-50% RH) with low ventilation for 90 min. Judges (visitors) evaluated the odour of the chamber before and during, and after the 90-min period of occupancy. Odour intensity increased throughout occupancy and decayed afterwards. However, therate of decay exceeded that anticipated from ventilation rate alone. The results implied that body odour is unstable with a half-life of 55 min. This instability will influence quantitative requirements for ventilation during nonsmoking occupancy.
