摘要：

目的:探讨铁路危险品货运站(简称危货站)空气污染对作业工人健康的危害.方法:选择天津地区某铁路危货站和普通货运站(简称普货站)的作业工人为调查对象,对其职业接触程度及肿瘤、呼吸系统、血液系统等的疾病史进行回顾性流行病学调查,并采用流式细胞仪分析受试人员外周血淋巴细胞的细胞周期.结果:危货站作业工人的呼吸道刺激症状、慢性支气管炎和恶性肿瘤等的发生率明显高于普货站;危货站作业工人血淋巴细胞周期进程加快,从G0/G1时相进入S时相的淋巴细胞增多.结论:铁路危货站空气污染对作业工人健康具有明显危害.

Objective To explore the harmful effects of the air pollution from chemical dangerous goods in railway transport station(CDGRTS) on worker’s health.Methods A total number of 215 workers from CDGRTS and railway transport station of common goods in Tianjing city were selected and investigated by a retrospective cohort study on current situation of worker’s health.Meanwhile,the circulatory lymphocytes in the worker’s blood samples were detected with Flow Cytometry.Results The incidence of stimulating symptoms of respiratory system,chronic bronchitis and cancer occurrence in workers from CDGRTS were statistically higher than those in control groups.The lymphocytes in S phase were increased significantly compared with those in control groups.Conclusion It indicates that the air pollution of CDGRTS could cause obvious harmful effects on worker’s health.
