Extraction of /sup 14/C labeled benzo(a)pyrene and anthracene from contaminated soil samples by Soxhlet and Polytron techniques was studied in a replicated 2/sup 4/ factorial experiment. Soxhlet extraction gave higher recoveries than Polytron extraction. Percent recoveries from both techniques were greater at a 50 /sup +/g/g contamination level than at 5/sup +/g/g. Pyrolysis of the extracted residue followed by trapping of /sup 14/CO/sub 2/ corroborated the extraction results. In addition, analysis of the residue showed a significant increase in /sup 14/C due to soil sterilization with HgCl/sub 2/ and an interaction effect between PAH and concentration. The effects of PAH, concentration, and HgCl/sub 2/ treatment on extraction and sorption were the same with both extraction methods. 6 references, 3 tables.
