英文摘要: High-accuracy analyses of polycyclic aromatic hydrocarbons (PAHs) in lipid matrix-based biological samples are highly necessary. We investigated the cleanup performance of the commercially available molecularly imprinted polymers (MIPs) to analyze PAHs in various biological samples (i.e., butter, peanut oil, pork belly, and human umbilical cord), and compared this method with the commonly used gel permeation chromatography (GPC). After primary cleanup with a MIP or GPC column, the extracts were further cleaned with a neutral aluminum oxide column. Then, we measured 16 PAH congeners using gas chromatography-mass spectrometry. The MIP method allowed PAH recovery levels as high as those measured with the GPC method to be obtained. More than 95% of the crude fats of butter, peanut oil, and...
