目的 探讨交警呼出气一氧化碳（ＣＯｂ） 快速检测结果。方法 采用英国制造的一氧化碳 （ＣＯ） 微型监测仪监测２ ０１５ 名广州市交通警察ＣＯｂ 水平并调查询问某些相关因素如吸烟和职业暴露等。结果 ＣＯｂ 呈正偏态分布， 浓度范围为３－７５ ～５３－７５ ｍｇ／ ｍ ３， 中位数１１－２５ ｍｇ／ ｍ ３， 异常率４２－３ ％ （８５２／２ ０１５） ， ＣＯｂ 浓度随吸烟量、烟龄的增加而增加， 监测前１ 小时内吸烟者其浓度较高； 不吸烟男交警， 不同区域、岗位ＣＯｂ 浓度旧市区高于新市区， 定岗指挥交通高于内勤和机动巡逻。结论： 吸烟和接触汽车废气是使交警ＣＯ 水平增加的主要因素， 本研究所用ＣＯ 监测仪使用方便， 检测快速， 可试用于职业接触ＣＯ 人群的预防性健康监护。
Objective To investigate the rapid detection of exhaled carbon monoxide (COb) in traffic police. Methods The CO 2 levels of 2 015 Guangzhou police officers were monitored using a carbon monoxide (CO) monitor manufactured in the United Kingdom. The COb levels were investigated and asked for relevant factors such as smoking and occupational exposure. Results COb showed a positive skewed distribution with a concentration range of 3-75-53-75 mg / m 3, a median of 11-25 mg / m 3, and an abnormality rate of 42-3% (852/2 015). COb concentration was positively correlated with smoking Quantity and age of smokers increased, smoker’s concentration was higher within 1 hour before monitoring. Non-smoker male traffic police, COb concentration in different regions and post was higher in old urban areas than in new urban areas, . Conclusion: Smoking and exposure to vehicle exhaust are the main factors that increase the level of traffic police CO. The CO monitor used in this study is easy to use and has rapid detection. It can be used for preventive health monitoring in occupational exposure to CO population.
