Iron overload is a risk factor that triggers a series of health problems. The toxicity of iron is that iron can catalyze the formation of oxygen free radicals and can be used as a nutrient necessary for the growth of microorganisms and tumor cells. The sensitivity of human cells to iron toxicity varies widely. Causes of iron overload include genetic factors, behavioral factors and environmental factors. With the rapid development of modem industry, iron and its compound dust distribution industry and the increasingly widespread, in the iron pigment production, mechanical casting, iron ore mining and iron smelting operations will produce a lot of iron and its compound dust, Its impact on the human body has been of concern. Long-term exposure to iron and its compounds can cause different degrees of damage to the respiratory system, resulting in iron in vivo disorder. The relationship between iron metabolism and lung injury has also begun to be concerned, and maintaining iron homeostasis is important for lung injury and its protection. 展开更多
