目的了解大气铅污染与交警铅水平及健康状况的关系,为提高交通警察健康水平、降低铅污染提出对策。方法选取警龄在一年以上,无其它职业性铅接触史,在主要交通岗一线执勤、年龄小于50岁的交通警察为实验组,检测其血铅、尿铅含量,并对吸烟、饮酒等一般状况作问卷调查,选取远离交通要道的某大专学校学生为对照组,对影响交警血铅水平的因素进行了单因素相关分析,并进行了危险因素Logidtic回归。结果通过对120名交通警察血铅、尿铅水平铅检测,其血铅水平为94.84±26.2μg/L(x±s);尿铅水平为6.12±3.50μg/L(x±s);且血铅、尿铅水平明显高于对照组,P<0.001;经分析交警血铅水平与年龄、警龄、尿铅、执勤时间呈正相关关系(P<0.001,P<0.05)与血红蛋白呈负相关(P<0.001)。结论交通警察这一特殊职业群体受大气污染是严重的,应引起政府有关部门的高度重视,采取综合防治措施,提高健康水平。
Objective To understand the relationship between atmospheric lead pollution and the level and health status of traffic police, and to provide measures to improve the health level of traffic police and reduce lead pollution. Methods The police officers aged over one year with no history of occupational exposure to lead were employed in this study. Traffic policemen who were first on duty at the main traffic posts and under the age of 50 were selected as the experimental group to test their blood lead and urinary lead levels, and their smoking, drinking, etc. General situation for the questionnaire survey, select a school away from the traffic arteries of a college student control group, the impact of traffic police blood lead levels were single factor correlation analysis, and the risk factors Logidtic regression. Results The levels of blood lead and urine lead in 120 traffic police officers were 94.84 ± 26.2μg / L (x ± s); the urinary lead level was 6.12 ± 3.50μg / L (x ± s); and Blood lead and urine lead levels were significantly higher than those of the control group (P <0.001). There was a negative correlation between blood lead level and the age, seniority, urinary lead and time of service (P <0.001, P <0.05) (P <0.001). Conclusion The traffic police, a special occupational group, is seriously polluted by the air. It should arouse the attention of relevant government departments and adopt comprehensive prevention and control measures to improve the health level.
