铅锌矿70名作业人员尘肺病发生状况分析

Analysis on Pneumoconiosis Incidence of 70 Workers in lead zinc Plant

目的了解铅锌矿职工尘肺病发生现状。方法依据《职业健康监护管理办法》和GBZ 70-2009《尘肺病诊断标准》及《尘肺病诊断标准片》,对1989年以来某市赴凉山州某铅锌矿70名务工人员进行职业健康检查和尘肺病诊断。结果诊断为尘肺病的61人,尘肺病发生率87.14%,明显高于某市煤炭系统尘肺病(4.38%)的发生率。其中矽肺Ⅲ期36例,占矽肺病例的59.01%,明显高于1949—1998年四川省Ⅲ期矽肺11.62%的构成比例。结论该铅锌矿务工人员矽肺病发生呈现发病率高、高期别矽肺发生率高等严重危害劳动者健康的特点,应加强职业健康监护及劳动防护措施的改善,使劳动者的健康得到合法保障。

[Objective]To understand the incidence of pneumoconiosis in lead and zinc plant workers.[Methods]According to＂Occupational Health Surveillance Measures＂,＂diagnostic criteria of pneumoconiosis＂（GBZ70-2009） and ＂standard chest radiograph for pneumoconiosis diagnosis＂,occupational health examination and pneumoconiosis diagnosis were conducted on 70 workers from another city who worked in a lead and zinc plant in Liangshan State since 1989.[Results]A total of 61 workers were diagnosed pneumoconiosis,the incidence was 87.14% which was significantly higher than that of coal industry in a city（4.38%）.36 cases were silicosis stage Ⅲ,occupying 59.01% of total silicosis cases which was significantly higher than composition ratio of silicosis stage Ⅲ in Sichuan Province during 1949-1998（11.62%）.[Conclusion]It shows a feature of high incidence of pneumoconiosis and high stage pneumoconiosis in workers of this lead and zinc plant,which does harm to the health of workers seriously.Occupational health surveillance and the improvement of labor protection should be strengthened to ensure the legal protection of the health of workers.
