A study was designed to examine the elimination rate of alcohol from the body of the local Chinese after consumption of different types of alcoholic drinks. The breath alcohol of 184 healthy volunteers was determined and converted into blood alcohol levels after they finished drinking. Information on the type and volume of alcoholic drinks consumed, age group, sex, drinking habit, and drinking on empty stomach or with/after meal was recorded for each participant. The results show that the elimination rate of an individual can be explained in terms of physiological variables including sex and drinking habit. The determined elimination rates allow forensic toxicologists to back calculate the blood alcohol concentration (BAC) of the drivers at the time of accident in drunk driving cases. The elimination rates of blood alcohol at 95% prediction intervals for male and female are in the range of 9.5-23.8 mg/100 ml/h and 11.1-37.1 mg/100 ml/h, respectively.
一项研究旨在检测当地中国人饮用不同类型酒精饮料后酒精在体内的消除率。在184名健康志愿者饮酒完毕后，测定其呼出气体中的酒精含量，并换算成血液中的酒精含量。记录了每位参与者所饮用酒精饮料的类型和量、年龄组、性别、饮酒习惯以及空腹饮酒还是在就餐时/就餐后饮酒。结果表明，个体的酒精消除率可以通过包括性别和饮酒习惯在内的生理变量来解释。所测定的消除率可让法医毒理学家在酒驾案件中倒推事故发生时司机的血液酒精浓度（BAC）。男性和女性血液酒精消除率在95%预测区间分别为9.5 - 23.8毫克/100毫升/小时和11.1 - 37.1毫克/100毫升/小时。
