In this study, the author examined (a) levels of airborne pollutants from environmental tobacco smoke in 8 restaurants, and (b) changes in urinary cotinine and nicotine levels among 97 nonsmoking subjects (i.e., 40 restaurant employees, 37 patrons, and 20 referents). Airborne pollutant levels were significantly lower in the control environments than in the nonsmoking dining rooms in which smoking was not permitted, and the levels were significantly lower in the dining rooms in which smoking was not permitted than in the dining rooms in which smoking was permitted. Levels of urinary cotinine and nicotine increased among subjects in the dining rooms in which smoking was permitted, and the increase was significantly greater in employees than patrons. There was a significant positive correlation between levels of urinary nicotine increase and the levels of airborne nicotine and solanesol. The results of this study support the restriction of smoking to designated areas that have separate ventilation systems, or the prohibition of smoking in restaurants.
在本研究中，作者检测了：(a) 8家餐厅环境烟草烟雾中的空气传播污染物水平；(b) 97名非吸烟受试者（即40名餐厅员工、37名顾客和20名对照者）尿液中可替宁和尼古丁水平的变化。对照环境中的空气传播污染物水平显著低于禁止吸烟的非吸烟餐厅，而禁止吸烟的餐厅中的污染物水平又显著低于允许吸烟的餐厅。在允许吸烟的餐厅中，受试者尿液中的可替宁和尼古丁水平升高，且员工的升高幅度显著大于顾客。尿液中尼古丁升高水平与空气中尼古丁和茄尼醇水平之间存在显著正相关。本研究结果支持将吸烟限制在设有独立通风系统的指定区域，或在餐厅内禁止吸烟。
