The objectives of this study were to estimate the extent of occupational health monitoring for dust and pneumoconiosis in the foundry industry and to assess dust levels and the prevalence of pneumoconiosis in a group of foundries. In only 13 (16%) of the 82 foundries that responded to a postal questionnaire were regular periodic full-sized chest radiographs done. Dust levels were measured every 3 years or more frequently in 20 foundries (24%). An uncontrolled dust hazard was evident in all 9 foundries surveyed between 1983 and 1992. The prevalence of silicosis ranged from 0% to 10.3% and increased with duration of service. The study provided convincing evidence of neglect of occupational health by the foundry industry.
本研究的目的是估计铸造行业粉尘及尘肺病职业健康监测的程度，并评估一组铸造厂的粉尘水平和尘肺病患病率。在回复邮寄问卷调查的82家铸造厂中，只有13家（16%）定期进行全尺寸胸部X光检查。20家铸造厂（24%）每3年或更频繁地测量粉尘水平。1983年至1992年期间调查的所有9家铸造厂都存在明显的无控制粉尘危害。矽肺病患病率从0%到10.3%不等，并随服务年限增加而上升。该研究提供了令人信服的证据，证明铸造行业忽视职业健康。
