• Description:
  Environmental correlates of mortality patterns among hourly workers were investigated at a large malleable and gray iron foundry. A case/control study for nonmalignant respiratory disease and lung cancer was conducted of all hourly employees who worked at the facility for at least 10 years and who died in the period 1970 through 1981 (278 workers). There was a significant proportionate excess of lung cancer and nonmalignant respiratory disease among the workers in the foundry; workers in the finishing department showed the strongest associations for both diseases. Company industrial hygiene reports were reviewed for the period 1947 to 1976; these contained counts of airborne foundry dust particles and carbon- monoxide (630080). Measured levels of dust containing crystalline silica (14808607) were roughly similar in most production areas, including finishing, melting, molding, pouring, shakeout, and sand preparation. The arithmetic mean dust level was 10 million particles per cubic foot (mppcf) and the geometric mean was 6mppcf, when averaged over a period of 30 years; 11 percent of samples exceeded 20mppcf. The authors conclude that a permissible exposure limit of 10mppcf for foundry dust, approximately 145 micrograms/cubic meter of respirable crystalline silica, is inadequate to protect against malignant and nonmalignant respiratory disease.
