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.
双酚A(BPA)和其他双酚类化合物(BPs)被证明具有潜在的内分泌干扰特性。BP暴露的主要来源是饮食。欧洲食品安全局(EFSA)设定了BPA的每日临时可耐受摄入量(t-TDI)为4微克/千克体重。
在中国第六次总膳食研究(TDS)的复合食品样本中检测到BPs,其比例为27.1%-78.5%。平均成年人每日通过饮食摄入BPA和双酚S(BPS)的估计量分别为18.1纳克/千克体重和22.2纳克/千克体重。BP的主要饮食来源是谷物、水和饮料、肉类以及蔬菜。
根据EFSA设定的t-TDI,BP的饮食摄入量对中国普通人群构成的风险较低。BPS的暴露水平高于BPA,这凸显了加强对食品中BP替代品监测的必要性。
