一氧化碳（CO）是交通尾气造成的空气污染的重要组成部分。一氧化碳可引起慢性中毒，其最初症状是头痛、视力模糊、注意力不集中和精神错乱。随着土耳其大都市地区车辆数量的增加，城市空气中的一氧化碳浓度也有所增加，首都安卡拉的情况尤其如此，特别是在某些地点。就二氧化碳对人类的影响而言，交警是面临风险的人群，因为他们在城市拥挤的路口执行任务时会吸入富含二氧化碳的空气。在这些路口执勤的交警在高浓度的二氧化碳中暴露至少 6 小时。本研究旨在调查安卡拉市拥挤路段暴露于高浓度一氧化碳的交警（交通组织者），并了解该危险群体中是否存在慢性一氧化碳中毒。这些横截面的环境空气中的二氧化碳水平也与目标人群呼出空气中的二氧化碳测量值进行了比较和相关。通过评估警察填写的特殊调查问卷，还考虑了吸烟、一般健康状况、家庭使用的供暖系统类型等其他因素。出于比较目的，成立了一个由不从事街道交通活动的文员警察组成的对照组。
Carbon monoxide (CO) is an important component of air pollution caused by traffic exhaust fumes. CO can cause chronic poisoning which shows its first symptoms as headaches, blurry vision, difficulty in concentration, and confusion. With the increasing number of vehicles in metropolitan areas of Turkey, the CO level has also increased in the city air as is the case in the capital city of Ankara, especially at certain locations. As far as the effects of CO on humans are concerned, traffic policemen are the population group under risk due to their inhalation of CO-rich air while on duty at the crowded cross-sections of the city. The traffic policemen on duty at these cross-sections are exposed to these high levels of CO for at least 6 h. This study was performed to investigate the traffic policemen (traffic organizers) who are exposed to high concentrations of CO at crowded cross-sections of Ankara City and to find out if chronic CO intoxication exits among this risk group. The CO levels in the ambient air at these cross-sections have also been compared to, and correlated with measurements of CO in the expired air of the target population. Additional factors like smoking, general health status, type of heating systems used at home, etc., have been taken into consideration by evaluating special questionnaires filled out by the policemen. A control group of clerk policemen, who were not engaged in street traffic activities was formed for comparative purposes.
