An extensive survey has been designed to provide detailed information on carbon monoxide (CO) concentration in the main transport modes and along heavy traffic routes in the Athens urban area. Specifically the study identifies the main factors affecting CO exposure during commuting. Several portable, electrochemical CO monitors (Solomat's MPM4100), were used to record the in-vehicle CO concentrations every 15 s. Measurements were performed during rush hour periods. Field monitoring was conducted in summer 1998 and winter 1998-1999. Exposure estimates were compared to WHO guidelines. The findings showed that the mean CO level over trips of 30 min was 21.4 ppm for private car against 10.4, 9.6, 4 and 11.5 ppm for bus, trolley, electric train and pedestrians, respectively. Transport mode, route, monitoring period and season had a significant influence on the measured CO concentrations. The study points out the importance of microenvironmental monitoring, instead of using fixed-site data in assessing commuter's CO exposure.
一项广泛的调查旨在提供雅典市区主要交通方式及繁忙交通路线沿线一氧化碳（CO）浓度的详细信息。具体而言，该研究确定了通勤期间影响一氧化碳暴露的主要因素。使用了几台便携式电化学一氧化碳监测仪（索洛马特公司的MPM4100），每隔15秒记录一次车内一氧化碳浓度。测量在高峰时段进行。现场监测于1998年夏季和1998 - 1999年冬季进行。将暴露估计值与世界卫生组织的指导方针进行了比较。研究结果表明，私家车30分钟行程的平均一氧化碳水平为21.4 ppm，而公交车、无轨电车、电动火车和行人的这一数值分别为10.4 ppm、9.6 ppm、4 ppm和11.5 ppm。交通方式、路线、监测时段和季节对测量的一氧化碳浓度有显著影响。该研究指出了在评估通勤者一氧化碳暴露时进行微环境监测的重要性，而不是使用固定站点的数据。
