This technique involves the use of simultaneous microwave-assisted digestion (MAD) and micro-solid-phase extraction (μ-SPE), in which the sorbent is held within a propylene membrane envelope, with gas chromatographic-mass spectrometric (GC-MS) analysis. The POPs studied included eleven organochlorine pesticides and five polychlorinated biphenyl congeners. Optimization of the MAD-μ-SPE parameters was performed. The relative standard deviations (RSDs) of the method ranged from 0.14 to 12.7%. Correlation coefficients up to 0.9999 were obtained across a concentration range of 1.25-50 ng g-1. The method detection limits for POPs ranged from 0.002 to 0.009 ng g-1. A preliminary study applying the MAD-μ-SPE procedure to human ovarian cancer tissue showed that it was capable of detecting the presence of a wide spectrum of different POPs in benign and malignant tumors. © 2007 Elsevier B.V.
