A critical evaluation of recent literature utilizing pressurized liquid extraction (PLE) for environmental analysis is presented by compound class. Overall, the extraction efficiency of PLE, using the appropriate solvent, temperature and pressure for extraction, is similar to that of Soxhlet extraction. PLE has been used for some classes of compounds that are thermally labile (e.g., explosives) and may require acidic conditions for extraction (e.g., organometallic compounds). References to recent applications are presented emphasizing studies which utilize unspiked, natural matrices and studies that compare PLE to alternate extraction techniques.
