摘要

The use of bisphenol A (BPA) has been restricted in many countries because of its potential health effects. As a result of these restrictions, a group of bisphenol analogues that are structurally similar to BPA have been developed as the alternatives for industrial applications. However, latest researches indicated that these chemicals have similar endocrine-disrupting effects as BPA in humans. Moreover, only a limited number of studies have attempted to monitor the exposure level in humans of other bisphenol analogues. In the present study, the concentrations of seven bisphenols, including bisphenol S (BPS), bisphenol F (BPF), bisphenol B (BPB), BPA, bisphenol AF (BPAF), tetrachlorobisphenol A (TCBPA) and tetrabromobisphenol A (TBBPA), in human urine samples were measured by liquid chromatography coupled to mass spectrometry (LC–MS/MS) following the enzymatic hydrolysis of glucuronidase/arylsulfatase and liquid–liquid extraction (LLE). Under the optimised conditions, high recoveries (81.6–116.8%) were obtained for all the analytes, and the relative standard deviations (RSD, %) were less than 16.4% (n = 6). The isotopic internal standard calibration curves for each of the target compounds exhibited excellent linearity (r2 > 0.99) and the limit of quantification (LOQ) for the analytes in urine ranged from 0.024 to 0.310 ng mL−1. The method was applied to investigate the urinary levels of these seven bisphenols in a cohort of residents living near a BPAF manufacturing plant in south China. BPS, BPF, BPA and BPAF were detected in urine samples at concentrations ranging from
