在正常条件下人每天吸到体内的灰尘通过各种方式将其阻留和排出体外。但在异常条件下,如生产环境空气中含有过量的粉尘以及个体生理功能上的差异,长期大量吸入粉尘会造成尘肺。除尘肺外在矿山生产中罕有中毒事例,所以在劳动卫生职业病工作中较少注意矿尘成分中化学物质所造成的危害。考虑到外因的远期效应,我们研究了金属矿石中硅,镍,铬,铁,锡,砷等元素在矿工肺内的沉积状态。
Under normal conditions, people absorb the body’s dust every day by a variety of ways to retain it and excreted. However, abnormal conditions, such as the production environment, the air contains excessive dust and individual differences in physiological functions, prolonged inhalation of dust can cause pneumoconiosis. In addition, there are rare cases of poisoning in mine production outside of the lungs. Therefore, the work done in occupational health and occupational diseases has paid less attention to the hazards caused by the chemical substances in the dust components. Taking into account the long-term effects of external factors, we studied the deposition of silicon, nickel, chromium, iron, tin, arsenic and other elements in miners’ lungs.
