目的评价环境铅对交通警察健康影响的现状,探讨其影响因素。方法抽取城市外勤交通警察126人,测定其工作场所空气中铅浓度。调查其健康状况及环境铅对其健康影响;测定血铅、尿铅、血清超氧化物歧化酶(SOD)、血红蛋白,并与对照组(无铅接触史125名)进行比较。结果交通警察工作场所空气中铅浓度并不超过国家职业卫生标准。交通警察组自诉头晕、头痛、乏力、记忆减退及多汗症状百分比、血铅、尿铅水平明显高于对照组(均P<0.01),患高血压者明显多于对照组(P<0.05),SOD明显低于对照组(P<0.01)。血铅与外勤年限呈正相关(r=0.4539,P<0.001),与血红蛋白呈负相关(r=-0.4986,P<0.001)。结论长期接触低浓度环境铅明显影响交通警察健康水平。 Objective To evaluate the status quo of health impact of environmental lead on traffic police and discuss its influencing factors. Methods A total of 126 city traffic police officers were taken to determine the concentration of lead in the workplace air. To investigate their health status and environmental lead on their health effects; blood lead, urinary lead, serum superoxide dismutase (SOD), hemoglobin, and compared with the control group (125 lead-free history) were compared. Results The concentration of lead in the air of traffic police workplace did not exceed the national occupational health standards. The percentage of blood lead and urine lead were significantly higher in traffic police group than those in control group (all P <0.01), and those with hypertension were significantly higher than those in control group (P <0.05) , SOD was significantly lower than the control group (P <0.01). Blood lead was positively correlated with the length of field (r = 0.4539, P <0.001) and negatively correlated with hemoglobin (r = -0.4986, P <0.001). Conclusion Long-term exposure to low concentrations of environmental lead obviously affects traffic police health.
