便携式一氧化碳检测仪（催化电极）用于记录封闭公共设施内的一氧化碳浓度，包括夜总会、酒吧、餐馆、商店、医院和公共交通车辆。一氧化碳浓度最高的是夜总会，晚上室内读数平均为 13.4 ppm，比室外读数高 4.1 +/- 1.5 ppm。在一处通风不良的场所中，数值范围为 20 至 40 ppm，房间周围存在很大的梯度。充分通风并对餐厅员工进行缺血性心脏病筛查应该可以防止香烟引起的一氧化碳积聚问题。不幸的是，烟雾中其他成分的浓度低得多，会导致非吸烟者出现症状和肺功能变化。如果使用一氧化碳作为香烟烟雾积累的指标，浓度不应超过环境读数 5 ppm 以上。
A portable carbon monoxide detector (catalytic electrode) was used to record carbon monoxide concentrations in enclosed public facilities, including night clubs, bars, restaurants, stores, hospitals, and public transit vehicles. The highest concentrations of carbon monoxide were found in night clubs, where evening indoor readings averaged 13.4 ppm, which was 4.1 +/- 1.5 ppm higher than outdoor readings. In one poorly ventilated establishment, values ranged from 20 to 40 ppm, with substantial gradients around the room. Adequate ventilation and screening of restaurant employees for ischemic heart disease should prevent problems from cigarette-induced build-up of carbon monoxide. Unfortunately, much lower concentrations of other constituents of smoke cause symptoms and changes of pulmonary function in the nonsmoker. If carbon monoxide is used as an indicator of cigarette smoke accumulation, concentrations should not exceed ambient readings by more than 5 ppm.
