Abstract
This study describes a recently developed and rapid method to measure bisphenol A (BPA), 17β-estradiol (E2) and 17α-ethynylestradiol (EE2) in bile of fish using enzymatic hydrolysis of samples followed by solid-phase extraction and ultra-performance liquid chromatography with tandem mass spectrometry. The limits of quantitation (LOQ) for BPA, EE2 and E2 were 6.3 ng mLâ1, 12.5 ng mLâ1 and 6.3 ng mLâ1, respectively. These compounds were analyzed in bile of male English sole (Parophrys vetulus) collected from urban and non-urban sites in Puget Sound, WA, USA. The BPA and E2 concentrations (and occurrence) ranged from
