摘　　要：采用超高效液相色谱-串联质谱(UPLC-MS/MS)对278份广元市售食品中8种双酚类化合物(BPs)进行分析,并估算不同年龄和不同性别组人群的BPs每日膳食摄入量,评估居民通过膳食摄入BPs的情况和健康风险。结果表明:大部分(76.3%)市售食品含有BPs,含量在检出限(LOD)~59.08μg/kg之间,平均3.12μg/kg,其中罐头食品、谷类、水产类以及蔬菜中ΣBPs含量较高。BPA和BPS是主要的污染物,分别占总BPs的77.9%%和14.4%。不同年龄和不同性别组人群BPs每日膳食暴露水平在42.59~96.54 ng/kg bw/d之间,BPA对膳食暴露的贡献率最高,其次是BPS。BPs总暴露量随着年龄的增长呈下降趋势。2~19岁(发育关键期)人群的ΣBPs每日膳食摄入量(87.96 ng/kg bw/d)明显高于19岁以上人群的成人组(48.05 ng/kg bw/d)。各组人群由饮食接触引起的BPs健康风险较低,其从膳食接触到的BPs均低于欧洲食品安全局暂定的BPA日允许摄入量(t-TDI,4μg/kg bw/d)。因BPA类似物的生产和应用在全球范围呈上升趋势,故其引起的健康风险应持续被关注。Bisphenols(BPs)are suspected posing potential endocrine disrupting properties.Occurrence of BPs has been reported in environmental matrices.BPs might migrate into foodstuffs through food packaging materials or contaminated water and soil.Information on the occurrence of bisphenols,other than BPA,in foodstuffs,however,is scarce.Dietary exposure is of paramount importance way for human health.In this study,eight BPs,including BPA,BPS,BPP,BPB,BPAP,BPAF,BPF and BPZ,were analyzed in market foodstuffs(N=278)collected from Guangyuan,Sichuan,China,using ultra-performance liquid chromatography tandem mass spectrometry(UPLC-MS/MS)foodstuffs were divided into ten categories of beverages,dairy products,eggs,cquatic foods,cereals,meats,fruits,vegetables,canned food and packaged drinking water.Bisphenols were found in the majority(76.3%)of the food samples,and the total concentrations of bisphenols(ΣBPs:sum of eight bisphenols)were in the range of below the limit of detection(LOD)to 59.08μg/kg,with an overall mean value of 3.12μg/kg.The higher overall mean concentration ofΣBPs was found in canned food,cereals,cquatic foods and vegetables.The predominant bisphenol analogues found in foodstuffs were BPA and BPS,which accounted for 77.9%and 14.4%of the total BPs concentrations,respectively.On the basis of measured concentrations and daily ingestion rates of foods,the daily dietary intakes of bisphenols(calculated from the mean concentration)were estimated to rang from 42.59 ng/kg bw/d to 96.54 ng/kg bw/d for different age and gender groups.BPA contributed to the majority of the total intakes of the BPs,followed by BPs.The daily dietary intakes of BPs showed a decrease with the growth of the age.It should be noted that dietary intakes of people aged 2-19 year old(critical time of development,87.96 ng/kg bw/d)were obviously higher than that of aged above 19(48.05 ng/kg bw/d).Based on the t-TDI set by EFSA(4μg/kg bw/d for BPA),the BPs through dietary intake pose low risks on the general population even summarization exposure le
