Abstract
An industrial hygiene and epidemiological survey was conducted at a midwestern mineral wool production facility. Personal and area air samples were collected to determine worker exposures to respirable mineral wool fibers. Sample periods ranged from 30 minutes to approximately 2 hours. Fiber size and concentration were determined using phase contrast optical microscopy and transmission electron microscopy. The highest concentration observed on any single airborne fiber sample was slightly more than 2 fibers per cubic centimeter. More than 90 percent of the fibers were longer than 5 micrometers. Airborne fiber size measurements revealed median fiber lengths ranging from 6.8 to 24.8 micrometers and median fiber diameters ranging from 1.7 to 2.7 micrometers. Approximately 75 percent of all airborne fibers were smaller than 3.5 micrometers in diameter and shorter than 50 micrometers in length. Epidemiological data did not indicate any increased cause specific mortality among the workers. The authors note that the epidemiological data is still being analyzed, and that possible adverse effects may be implicated for workers exposed 30 years ago.
