• Description:
  Six solvents and four techniques for the extraction of polynuclear aromatic hydrocarbons (PAH) from diesel exhaust particulate collected on Teflon coated glass fiber filters were evaluated. Two sets of eight replicate samples, collected using six extraction solvents, were analyzed for five specific PAH: fluoranthene (206440), pyrene (129000), benz(a)anthracene (56553), benzo(k)fluoranthene (207089), and benzo(a)pyrene (50328), using high pressure liquid chromatography with fluorescence detection. There was little difference between the extraction of the lighter PAH, fluoranthene and pyrene, with the different solvents. However, the heavier PAH, benz(a)anthracene, benzo(k)fluoranthene, and benzo(a)pyrene were recovered more efficiently with toluene and methylene-chloride than with acetonitrile, methanol, 2-propanol or acetone. Acetonitrile and toluene were used as the solvents in the evaluation of the four extraction techniques: simple mechanical agitation, ultrasonic agitation, refluxing solvent, and soxhlet extraction. Soxhlet extraction was superior to the other three techniques for the extraction of all the PAH, with the possible exception of pyrene. The author concludes that of the solvents and techniques tested, soxhlet extraction using either methylene- chloride or toluene provide optimum conditions for the extraction of PAH from filter samples of diesel exhaust, but other conditions may be optimal for extraction of PAH from samples other than diesel exhaust.
