Abstract: A several-year survey (2000-2006) documents a continuing occurrence of bisphenol A (BPA), bisphenol A diglycidyl ether (BADGE), and bisphenol F diglycidyl ether (BFDGE), including their derivatives, migrating from packaging into food. A wide range of bisphenols levels (from traces up to hundreds µg/kg) in canned foodstuffs available at the Czech retail market was found. An analytical procedure suitable for routine monitoring of bisphenols in various matrices was validated. Crude extracts (obtained by dichloromethane extraction in ultrasonic bath) were purified by gel permeation chromatography (GPC), identification/quantification was carried out by HPLC/FLD method. Optimised procedure allowed to measure trace levels of the target analytes (LODs - 3 µg/kg) with good repeatability (RSDs - 3% at level 100 µg/kg) and recoveries exceeding 75%.
