a b s t r a c tThree commonly applied extraction techniques for persistent organic chemicals, Soxhlet extraction (SE), accelerated solvent extraction (ASE) and microwave-assisted extraction (MAE), were applied on soil and fish samples in order to evaluate their performances. For both PCBs and PBDEs, the two more recent developed techniques (ASE and MAE) were in general capable of producing comparable extraction results as the classical SE, and even higher extraction recoveries were obtained for some PCB congeners with large octanol-water partitioning coefficients (K ow ). This relatively uniform extraction results from ASE and MAE indicated that elevated temperature and pressure are favorable to the efficient extraction of PCBs from the solid matrices. For PBDEs, difference between the results from MAE and ASE (or SE) suggests that the MAE extraction condition needs to be carefully optimized according to the characteristics of the matrix and analyte to avoid degradation of higher brominated BDE congeners and improve the extraction yields.

“…[10][11][12][13] Even though a polar solvent such as acetone was absent in these extractions, quantitative results were obtained in most cases. This is mainly believed to be caused by the increased extraction temperature in PLE, which should not be below 100˚C.…”

“…This latter type of PLE applications are often termed selective PLE or SPLE. Even though PLE has been used with great success for the extraction of PCBs from sediments with conventional external clean-up 2,4,5 and for the extraction of PCBs from food and feed with integrated clean-up, 11,12 no investigations have so far been conducted to apply selective PLE to sediments containing PCBs. This note, for the first time, reports on the possibility of integrating extraction and clean-up in SPLE to obtain a fast analysis of PCBs in sediments.…”

A selective pressurized liquid extraction procedure (SPLE) was developed for a fast determination of polychlorinated biphenyls in sediment. The final method was performed at 100˚C with heptane/dichloromethane (90:10, v/v) as extraction solvent for 2 × 5 min. Sulfuric acid impregnated silica was placed downstream of the sample in the extraction cell to remove interfering components. This simultaneous extraction/clean-up was performed in 20 min, with an average congener recovery of 92% compared to a classical 24 h Soxhlet methodology and 2 h of external manual clean-up.
