An industrial hygiene study of diesel emissions exposures in an underground coal mine (SIC-1211) was conducted. The study was part of a NIOSH research program to investigate the health implications of diesel use in coal mines. Area and breathing zone samples taken in an underground coal mine were analyzed for carbon-monoxide (630080), carbon-dioxide (124389), carboxylic acids, nitrogen- dioxide (10102440), aldehydes containing 1 to 5 carbon atoms, aliphatic hydrocarbons, cyclohexane soluble materials, and total and respirable dust. The samples were taken in the intake air, haulage and feeder areas, and in the return air. The geometric means of area and breathing zone total dust samples were 0.49 to 1.64 and Geometric means of area and breathing zone respirable dust samples were 0.34 to 1.76 and 0.58 to 1.68mg/m3, respectively. Geometric means of the area and breathing zone nitrogen-dioxide samples were means of the area and breathing zone cyclohexane extractable fractions were 0.03 to 0.09 and 0.04 to 0.07mg/m3, respectively. The geometric means of the area and breathing zone aldehyde concentrations were 2 to 32 and 0 to 13ppm, respectively. Carbon- dioxide concentrations ranged from 0.04 to 0.08 percent. Carbon- monoxide concentrations ranged from 0 to 2ppm. Carboxylic acids concentrations were 2 to 6 parts per billion. Sulfate concentrations averaged less than 50 micrograms/m3. Hydrocarbon concentrations could not be determined due to difficulties with the charcoal sampling tubes. The authors suggest that nitrogen-dioxide and aldehyde concentrations can be used to quantify diesel exposures. These are better than particulates, as particulate concentrations are probably more dependent on coal dust than diesel emissions.
