钢铁铸造工人的工作过程基本上是在一个封闭式的车间内,可以接触多种空气污染物,例如矽尘、金属尘及某些化学物质等。其中有的化学物质,如甲基二异氰酸联苯(MDI)具有致敏作用。为了了解这些物质对作业工人健康的危害程度,尤其是对呼吸系统功能的影响,作者进行了本文调查。 调查对象为英国某地的钢铁铸造工人,计 The work of steel foundry workers is basically in a closed workshop with access to a variety of air pollutants such as silica dust, metallic dust and certain chemicals. Some of these chemicals, such as methyl diisocyanate (MDI), have a sensitizing effect. In order to understand the extent of the hazards posed by these substances to the health of workers and especially their effects on respiratory system function, the authors investigated this article. The survey was conducted for steel foundry workers in the United Kingdom
