Abstract:
Bisphenols (BPs), widely used in polycarbonate plastics and epoxy resins, are associated with potential health risks, yet many exposure sources remain inadequately characterized. This study employed a novel approach by integrating 7-day time-activity diaries with individualized urinary biomonitoring to capture overlooked BP exposure sources. Twelve adult participants meticulously documented their daily activities, including food intake, across seven consecutive days, while providing all urine voids for analysis. A total of 401 urine samples were collected and analyzed individually (without pooling) to assess temporal variations and exposure associations. Among the eight analyzed BPs, Bisphenol A (BPA) and Bisphenol S (BPS) were detected in over 70 %, with median concentrations ranging from below the limit of quantification (LOQ) to 1.46 ng/mL for BPA and
