In response to a request from the Oil, Chemical and Atomic Workers' Union, an investigation of reported heart problems, lung disease and hearing loss in workers at 3M Company (SIC-3295), Little Rock, Arkansas. The company employed about 235 workers in the production of roofing granules from nepheline-syenite. The air concentration of crystalline silica (14808607) was above the recommended limit of 50 micrograms per cubic meter of air. Air concentrations of trace metals were below the relevant exposure limits. Noise exposures in excess of the NIOSH recommended exposure limit of 85 decibels-A as an 8 hour time weighted average were recorded. Heart disease was reported by ten and lung problems were reported by four of the 35 employees. The substances used at the site were not associated with heart disease. Lung disease could not be conclusively related to occupational exposure. The authors conclude that a hazard existed from noise exposure. The authors recommend that exposures to dust, silica, and noise be reduced.
