A Study on the Size of Dust in Workplaces of a Shipyard / 예방의학회지

ABSTRACT

To obtain the basic information that can be used as a factor for explaining the diversity of welders' pneumoconiosis, the authors measured the concentrations of dust according to the size of dust in 71 workplaces of a shipyard where welders' pneumoconiosis have occurred. The concentrations of dust according to the size of dust showed no difference between workplaces regardless of kinds of work.
