Blood ethanol concentration predictions (BECPs) based on 8 h exposure average (mg/L). The BECP was calculated by using the PBPK model of ethanol with the following exposure condition previously estimated. For the day 1, the atmospheric ethanol concentration was 408 mg/m3 (time 0–3 h), 768 mg/m3 (time 3–6 h), and 1108 mg/m3 (time 6–8 h). For the day 2, the atmospheric ethanol concentration was 924 mg/m3 (time 0–3 h), 1224 mg/m3 (time 3–6 h), and 1518 mg/m3 (time 6–8 h).
