摘要
为了配合中国交通警察职业性影响及防护对策研究，以某市有代表性的七个交通路口进行环境监测，并对该区交通警察（外勤警１０４人，内勤警９３人）进行了健康状况检查和神经行为功能测试。结果表明：该市污染较为严重，交通噪声昼Ｌｅｑ日均值为７６．７５ｄＢ（Ａ），超过国家建议交通噪声Ｌｅｑ每日标准７０ｄＢ（Ａ），颗粒物浓度、一氧化碳、氮氧化物浓度超过大气环境质量三级标准。外勤警的呼吸系统、关节酸痛、眼结膜炎等症状和体征出现率、ＨｂＣＯ百分含量、收缩压与内勤警比较均有显著性差异。在排除年龄、工龄、文化程度等因素的ＮＣＴＢ测试，在情感特征、数字跨度、数字译码、提转捷度和目标追踪等方面，外勤警较内勤警有显著性差异。提示：交通警察（外勤警）的健康状况及神经行为功能变化与城市污染有关。
The health risk and neurobehaioral effects of air pollution and job performance of traffic police were clarified in Wuhan. The results showed that the air pollution of the city was severe, The daily mean traffic noise Leq reached 76. 75 dB(A) which was slightly higher than the national standard of 70 dB(A). The concentrations of total particulates,carbon monoxide,and nitrogen oxides all exceeded the national ambient air quality standards of grade Ⅲ. An exposed group of 103 traffic police and 94 non-traffic police as controls were examined. The results were summarized as follows : the frequency of symptoms, signs and biochemical data(levels of HbCO ) in the exposed group were significantly higher than those of controls. The results of NCTB test could be evident that there were significant differences between the exposed group and the control group in Mood state,Digit span,Digit symbol substitution Santa Ana dexterity and Pursuit aiming tests after the exclusion of the difference age,work-age and educational level. Thus these data suggested that the impacts of health status and neurobehavioral function status of traffic police were supposedly related to the air pollution and work load.
