The occupational carbon monoxide (CO) exposure of Denver traffic control personnel was evaluated during 8-hr workshifts using three parameters: (1) 98, 8-hr time-weighted average breathing zone air samples (personal dosimetry); (2) before- and after-workshift CO breath samples; and (3) 8-hr moving average, ambient CO levels during the fall and winter months. Different shifts and work experiences were taken into consideration. The data revealed greater CO exposure in subjects working on the street than controls working inside downtown buildings with respect to breath CO concentration and breathing zone air samples. The CO concentrations in the after-workshift breath samples were closely associated with the 8-hr time-weighted average CO levels. The greatest source of CO to the sample population was cigarette smoking, followed by occupational-related sources, and finally, the ambient background CO levels.
在8小时轮班期间，使用三个参数对丹佛交通管制人员的职业性一氧化碳（CO）暴露情况进行了评估：（1）98个8小时时间加权平均呼吸区空气样本（个人剂量测定）；（2）轮班前和轮班后的CO呼气样本；（3）秋冬季节8小时移动平均环境CO水平。研究考虑了不同的班次和工作经历。数据显示，就呼气CO浓度和呼吸区空气样本而言，在街上工作的受试者比在市中心建筑物内工作的对照组有更高的CO暴露。轮班后呼气样本中的CO浓度与8小时时间加权平均CO水平密切相关。样本人群中CO的最大来源是吸烟，其次是职业相关来源，最后是环境背景CO水平。
