发布时间:2018-08-29 12:05
【摘要】:目的探讨某集团公司近10年来尘肺发病情况,分析其发病特点及流行特征,为企业职业病防治提供参考依据。方法对2002-2011年底健康监护资料中新诊断为尘肺壹期47人,分析其发病率、发病年龄、工种、接尘工龄、粉尘浓度关系进行比较分析。结果该公司2002-2011年矿山开采工作面粉尘浓度由2.89 mg/m3下降至1.80 mg/m3,冶炼反射炉粉尘浓度由7.95 mg/m3下降至3.50 mg/m3。尘肺发病率从4.35‰下降至1.08‰,其中矽肺的发病率由7.96‰降至1.40‰,冶炼工尘肺发病率在0.29‰~2.08‰。尘肺总患病率为8.47‰,其中矽肺、冶炼工尘肺患病率分别为14.02‰、4.99‰(P0.01)。矽肺、冶炼工尘肺发病年龄分别为(49.20±5.80)岁、(45.50±5.90)岁(P0.05);接尘工龄分别为(18.70±5.60)年、(14.80±4.70)年(P0.05)。凿岩工、其他辅助工矽肺发病年龄分别为(45.60±5.50)岁、(49.60±6.70)岁(P0.05);接尘工龄分别为(15.65±3.50)年、(18.25±6.20)年(P0.05)。不同年限矽肺发病年龄、接尘工龄差异无统计学意义;不同年限冶炼工尘肺发病年龄、接尘工龄差异无统计学意义。结论该集团公司生产性粉尘浓度逐年下降,矽肺发病率下降明显。矽肺发病率比冶炼工尘肺发病率高,但冶炼工尘肺发病年龄比矽肺发病年龄小,冶炼工尘肺接尘工龄比矽肺短,这是否与冶炼工接触的粉尘类型等因素有关,需进一步研究证实。
[Abstract]:Objective to investigate the incidence of pneumoconiosis in a group company in the past 10 years, and to analyze the characteristics and epidemic characteristics of pneumoconiosis in order to provide reference for the prevention and treatment of occupational diseases in enterprises. Methods 47 newly diagnosed pneumoconiosis patients from 2002 to 2011 were analyzed. The incidence, onset age, type of work, length of exposure to dust and dust concentration were compared and analyzed. Results from 2002 to 2011, the dust concentration of mining face decreased from 2.89 mg/m3 to 1.80 mg/m3, from 7.95 mg/m3 to 3.50 mg/m3.. The incidence of pneumoconiosis decreased from 4.35 鈥,
