• Description:
  Goals of the NIOSH Work-Related Lung Disease (WoRLD) Surveillance Report include: effecting prevention, targeting research, and strengthening surveillance programs for occupational respiratory hazards among U.S. workers. Previous editions have provided limited information on workers' exposures to respiratory disease agents such as asbestos, coal mine dust, respirable quartz and cristobalite, cotton dust, and other pneumoconiotic agents. The most recent edition has expanded the exposure information to include: geometric mean exposures and percent of exposures exceeding regulatory and NIOSH recommended exposure limits (RELs) by year and major industry division. The sources of exposure information, previously limited to MSHA and OSHA inspector data, have also been expanded to include data from mine operators and OSHA consultation. Some general findings for the period 1990 to 1999 are: (1) for asbestos, the miscellaneous nonmetallic mineral and stone products industry had the greatest geometric mean exposure, 0.03 f/cc; the highest percentage of samples exceeding the permissible exposure limit, 26%; and the highest percent of samples exceeding the NIOSH REL, 41%; (2) the geometric mean respirable coal mine dust exposure of 0.5 mg/m3 MRE in coal mining was half the REL and 26% of the samples for the period 1995 to 1999 exceeded the REL; (3) the geometric mean respirable quartz exposures in metal mining, nonmetallic mining/quarrying, and miscellaneous nonmetallic mineral and stone products industries were 8, 2, and 1 times the REL; and (4) the geometric mean cotton dust exposure for the yam, thread, and fabric mills industry was 67% of the REL and 32% of OSHA's samples exceeded the REL. For each year between 1979 and 1999, at least 45% of pneumoconiotic agent exposures in the metal/nonmetal mining industry exceeded the REL. For the construction and manufacturing industries, the percent of exposures exceeding the REL ranged from 2% to 40%. [Description provided by NIOSH]
