采用流行病学方法研究尘肺流行情况,其用途是:识别、鉴定职业危害因素—粉尘,研究病因及其影响因素,探讨其对机体危害程度和作用条件;监测生产环境粉尘情况,估测对人群的危险度;研究发生,发展规律,剂量与反应关系,为制订国家卫生标准,诊断标准、预测发病趋势,规划防治措施提供参考依据,也是评价防尘、降尘措施效果的重要手段。现就实际工作存在问题,谈谈看法。 (一)影响发病因素 虽然尘肺病因是明确的,但就粉尘的理化性质和结构,影响其致病因素
The use of epidemiological methods to study the prevalence of pneumoconiosis, its purpose is to identify, identify occupational hazards - dust, the etiology and its influencing factors to explore the degree of harm to the body and the role of conditions; monitoring of production dust environment, the estimated population The risk, the occurrence, the law of development, the relationship between dose and response, provide a reference for formulating national health standards, diagnostic criteria, forecasting trend and planning prevention and control measures, and also an important means to evaluate the effect of dust and dust control measures. Now there is a problem with actual work, to talk about the views. (A) the impact of factors Although the cause of pneumoconiosis is clear, but the physical and chemical properties of dust and structure, affecting its risk factors
