Environmental samples were analyzed for crystalline silica (14808607), dust, iron-oxide (1309371), manganese (7439965), nickel (7440020), and carbon-monoxide (630080) at the Jones and Laughlin Steel Corporation (SIC-3310), Pittsburgh, Pennsylvania, in January and May 1981. The survey was requested by United Steel Workers of America, Local 1271 on behalf of 750 employees because of the reported high incidence of cancer among workers. A retrospective study of mortality experience was conducted. Quartz (14808607) was the only polymorph of crystalline silica detected above the lower limit of quantitation. Breathing zone samples showed quartz concentrations ranging from 0.04 to 1.24 milligrams per cubic meter (mg/m3), below OSHA standards of 5.0mg/m3. One sample contained iron at a concentration that was 24 percent of the OSHA limit. Manganese and nickel were present at 33 percent or less of OSHA and NIOSH standards. Settled dust was 42 to 72 percent quartz. Unexplained excess risk of cardiovascular renal disease in electric furnace workers and arteriosclerotic heart disease in mechanical maintenance workers was revealed. The authors conclude that a potential hazard exists from respirable crystalline silica. Masons are at risk for work related nonmalignant respiratory disease. Further investigation of silica exposures is recommended.
