Background: 1. Ukraine has large coal mining population (570,000); 370,000 coal miners; 200,000 support workers 2. Many employed at anthracite coal mines (3 study mines = 8,100); 3. U.S. mining population much smaller (114,453); 170 at underground anthracite mines; 27 operators 4. In 2000, 20 million tons of coal produced in Donetsk; almost all from anthracite mines; one mine can produce 600,000 tons in one year 5. In 2000, 980 million tons of coal mined in U.S.; 340 million tons from underground mines; 270,000 tons from underground anthracite mines (0.03% of total) 6. Respirable dust levels not previously measured in Ukrainian mining populations (only total dust) 7. Exposure project part of a larger study on incidence of occupational lung disease. Conclusions: 1. Personal exposures exceed U.S. MSHA PEL for respirable dust in 75 % of all samples with significantly higher exposures during mining; 2. Personal exposures exceed U.S. MSHA PEL for quartz in 37% of all samples; 3. Nearly all samples (98%) exceed the Ukrainian MACs for total dust exposure; 4. Correlations showed 31% of total dust respirable during mining and 52% during development; 5. May be useful in looking at historical total dust exposures but need to gather more data to establish relationship more firmly.
