A study of coal liquefaction and gasification plants: an industrial hygiene assessment, a control technology assessment, and the development of sampling and analytical techniques: volume IV - a method for sampling and analysis of polynuclear aromatic hydrocarbons in...
NIOSH, 1982 Jan; :1-44
Methods of sampling and analysis of polynuclear aromatic (PNA) compounds used in industrial hygiene studies of coal liquefaction and gasification facilities were described. Personal and area air samples were collected in cassettes containing 200 milligrams or 25 grams, respectively, of chromosorb 102. Flow rates during area sampling, 1.5 liter per minute. after collection, the samples were extracted with 300 milliliters (ml) of a methylene-chloride/methanol mixture in a soxhlet apparatus. The precision of the method was determined by analyzing samples spiked with 11 PNA. Stability of the samples was not significantly affected by storage up to 30 days. Relative standard deviations of the spiked samples ranged from 11.0 percent for 100 nanograms (NG) of 2-methylphenanthrene (2531842) to 66.7 percent for 10NG of dibenz(a,i)pyrene (189559).
