The solid-phase microextraction (SPME) method was developed to determine PAH free dissolved concentration (C) in field leachates from hazardous waste disposal. SPME technique, involving a 100-μm polydimethylsiloxane (PDMS) fiber coupled to GC-MS was optimized for determination of C. The following PAH were found in bioavailable form: acenaphthylene, acenaphthene, fluorene, phenanthrene, anthracene, fluoranthene, pyrene, with C varying between 2.38 and 62.35 ng/L. Conventional solvent extraction was used for measurement of total concentration (C) in the same samples, and ranging from 1.26 to 77.56 μg/L. Determining C of the hydrophobic toxic pollutants could give useful information for risk assessment of the hazardous waste. [ABSTRACT FROM AUTHOR]
