Abstract
What is already known about this topic?: Bisphenol A (BPA) and other bisphenolic compounds (BPs) are proved to pose potential endocrine disrupting properties. The primary source of BP exposure is the diet. European Food Safety Authority (EFSA) established a temporary tolerable daily intake (t-TDI) of BPA 4 μg/kg body weight per day. What is added by this report?: BPs were detected in composite food samples from the Sixth China Total Diet Study (TDS) at percentages of 27.1%-78.5%. The estimated dietary exposure of BPA and bisphenol S (BPS) for an average adult were 18.1 ng/kg body weight per day and 22.2 ng/kg body weight per day, respectively. The main dietary contributors for BPs were cereals, water and beverage, meat as well as vegetables. What are the implications for public health practices?: BP dietary intake poses low risks on the Chinese general population based on the t-TDI set by EFSA. BPS presented a higher exposure level than BPA, which highlights the need to strengthen the surveillance of BP alternatives in foodstuffs.
