肺内矿物粉尘的测定,在尘肺病因学、诊断及鉴别诊断、剂量-反应关系的研究中,占有十分重要的地位。例如,在确认一种新的致病矿物粉尘时,在确认一种新的尘肺时,就必须定性、定量地测定吸入并潴留于肺内的矿物粉尘。 吸入并潴留于肺内的矿物粉尘含量低,粒子极细小,罕见单一粉尘的潴留,组成比较复杂,用光镜和通常的化学分析方法,仅能提供初步的粉尘的大致特征,所以对肺内矿物粉尘的测定有其一定的难度。近年来,随着我国分析技术和仪器设备的发展
Determination of lung mineral dust in pneumoconiosis, diagnosis and differential diagnosis, dose-response relationship, occupies a very important position. For example, when identifying a new pathogenic mineral dust, mineral dust that has been drawn in and retained in the lung must be qualitatively and quantitatively determined when a new pneumoconiosis is identified. Inhaled and retained in the lungs of the mineral dust content is low, very small particles, rare single retention of dust, the composition is more complicated, with light microscopy and the usual chemical analysis methods, can only provide the general characteristics of the initial dust, so the lung Determination of mineral dust has its own degree of difficulty. In recent years, with the development of China’s analytical techniques and equipment
