Polychlorinated dibenzo-p-dioxins (PCDDs) and other organic compounds are solvent extracted from 10- to 20-g samples of fly ash from municipal incinerators with 200 mL of benzene using ultrasonic agitation for 1 h. A convenient filtering device is used to separate fly ash and solvent which is then concentrated to 100 ..mu..L using a rotary evaporator. Extracts are analyzed directly by gas chromatography/mass spectrometry, including selected ion monitoring for PCDDs. Results from five replicate analyses of a fly ash sample yielded averages and standard deviations (ng/g) for the tetra-to octachlorinated dibenzo-p-dioxins of 8.6 +- 2.2, 15.0 +- 4.0, 13.0 +- 3.4, 3.2 +- 1.0, and 0.4 +- 0.1, respectively. 2 tables, 3 figures.
