应用金属的不断增长,给许多生产过程中的粉尘成分带来了数量与质量的变化。因此,预防、诊断和治疗金属粉尘和蒸气作用于机体所引起的各种病变,具有特殊的意义。各种金属的特性对机体的影响已作过研究,但与各种金属及其化合物作用有关的粉尘病理问题,文献中介绍很少,且很矛盾。 由某些金属粉尘所引起的尘肺类型,如铁末沉着症、电焊工尘肺了解得较早,并把六十年代算作毒性损害的由金属粉尘和金属气溶胶导致的肺部疾患看作是尘肺的一种,现在,尘肺本身的定义已有改变,不仅包括明显的粉尘所致的肺纤维化,而且包括由粉尘作用引起的 The increasing use of metals has brought changes in quantity and quality to many of the dust components in the production process. Therefore, the prevention, diagnosis and treatment of metal dust and steam on the body caused by a variety of lesions, with special significance. The effects of various metal properties on the body have been studied, but the dust pathology problems associated with the action of various metals and their compounds have been poorly documented and contradictory. The types of pneumoconiosis caused by certain metallic dusts, such as iron-related complications, welder’s pneumoconiosis, are understood earlier and the lung diseases caused by metallic dusts and metallic aerosols, which were counted as toxic damages in the 1960s, Now, the definition of pneumoconiosis itself has changed, including not only the obvious dust-induced pulmonary fibrosis, but also the effects of dust
