A COMPARISON OF SOLID-PHASE EXTRACTION METHODS FOR BISPHENOL A IN CHEESE SAMPLES

In this study, four different solid phase extraction (SPE) methods were compared for the determination of bisphenol A (BPA) in cheese samples using HPLC-FD. All validated according to parameters; linearity, recovery, precision, detection and quantification limits (LOD-LOQ). Subsequently, BPA levels determined twenty commercially available Elazığ province. showed good performances quantitative analysis PBA, achieving very low LOD (0.16-0.39 µg/kg) LOQ (0.53-1.30 µg/ kg) values. The average fortification recoveries spiked (3-30 ranged between 93.1 100.8%. 55% had concentration ranging from 0.75 µg/kg 8.46 estimated daily intake (EDI) was measured as 0,001 BW per day. On basis EDI, consumption itself cannot be considered significant health problem, but results impose a systematic monitoring dairy products.
