不少人认为尘肺既然是由粉尘引起的,所以尘肺的病因已经很清楚了。但粉尘种类很多,性质也千差万别,而且也不是所有的粉尘都能引起“以肺纤维化为主”的尘肺。所以有些尘肺的病因到目前为止还不是很清楚的。因此,尘肺病因学研究这一课题,也是尘肺流行病学研究中一项重要内容。 为了做好尘肺的病因分析,首先应明确粉尘与尘肺的基本概念。粉尘:是无生命固体微粒组成的气溶胶;所以霉菌和微生物等组成的气溶胶不属于粉尘范围。尘肺:是指以肺部纤维化为主的全身性
Many people think that since the dust is caused by dust, so the cause of pneumoconiosis has been very clear. However, many types of dust, the nature varies widely, and not all of the dust can cause “pulmonary fibrosis-based” pneumoconiosis. So the cause of some pneumoconiosis is not yet clear. Therefore, pneumoconiosis etiology research this issue, pneumoconiosis is also an important part of the study. In order to do a good analysis of the cause of pneumoconiosis, we must first clear the basic concepts of dust and pneumoconiosis. Dust: An aerosol of inanimate solid particles; aerosols, such as molds and microorganisms, do not belong to the dust range. Pneumoconiosis: refers to the systemic pulmonary fibrosis
