A survey to measure baseline exposure to coal dust, asbestos (1332214), sulfur-dioxide (7446095) (SO2), nitrogen-dioxide (10102440) (NO2) fly-ash (68131748), nitric-oxide (10102439) (NO) sulfites (SO3) sulfates (SO4) and noise was conducted at the Tennessee Valley Authority (TVA) coal fired power facilities. Personal and area atmospheric samples were taken and historical exposure data examined. The geometric mean concentration (GMC) of atmospheric coal dust ranged from 0.5 to 1.2 milligrams per cubic meter (mg/cu m) in all facilities for the years 1974 through 1979, although GMCS from the individual facilities ranged from 0.4 to 1.6mg/cu m for that time period. The GMCs of atmospheric fly-ash ranged from 0.20 to 0.50 mg/cu m, substantially below the OSHA standard of 5mg/cu m. NO2 was not found in any appreciable concentrations, NO concentrations ranged from 1.0 to 51.4ppm. GMCs of asbestos decreased from 1.1 fibers per milliliter (f/ml) in 1973 to 0.05f/ml in 1979. Atmospheric mercury concentrations ranged from nondetectable to 0.5/mg/cu m, compared with the OSHA standard of decibels on the A-weighted scale as 8 eight hour time weighted exposures. Area sampling for ozone did not detect any ozone generated by facility operations. Atmospheric concentrations of ozone ranged from 0 to 14ppm.
