摘要
【目的】了解上海市市售小麦粉及其制品中脱氧雪腐镰刀菌烯醇(DON)的污染水平,评估上海市居民通过小麦粉及其制品摄入DON的健康风险。【方法】利用2017—2021年上海市市售小麦粉及其制品中DON的风险监测数据,结合上海市居民小麦粉及其制品的消费量,采用概率评估方法对小麦粉及其制品中的DON进行膳食暴露评估。【结果】小麦粉及其制品中DON的总体检出率为77.3%(1 041/1 347),含量均值为226.3μg·kg^(-1),P_(50)为130.0μg·kg^(-1),最大值为3 080.0μg·kg^(-1)。上海市全人群每日通过小麦粉及其制品摄入DON的平均暴露量和P_(95)暴露量(按体质量计)分别为0.279μg·kg^(-1)和1.146μg·kg^(-1),分别占DON每日耐受摄入量[TDI(按体质量计),1μg·kg^(-1)]的27.9%和114.6%。概率评估结果表明,6.1%的全人群DON的暴露量超过TDI值。其中,12.8%的≤6岁人群、16.4%的7~岁人群、3.9%的18~岁人群和3.2%的60~岁人群每日通过小麦粉及其制品摄入DON的暴露量超过TDI值。【结论】上海市部分人群每日通过小麦粉及其制品摄入DON存在一定的健康风险。<18岁人群每日经小麦粉及其制品摄入DON的健康风险须重点关注。
[Objective]To investigate the pollution level of deoxynivalenol(DON)in wheat flour and its products sold in Shanghai,and to assess the health risks of DON exposure for residents in Shanghai who ingested DON from wheat flour and its products.[Methods]Risk monitoring data of DON in wheat flour and its products sold in Shanghai from 2017 to 2021 were combined with the consumption data of wheat flour and its products by Shanghai residents.A probabilistic assessment method was used to assess dietary exposure of DON in wheat flour and its products.[Results]The overall detection rate of DON in wheat flour and its products was 77.3%(1041/1347),with a mean concentration of 226.3μg·kg^(−1),P50 of 130.0μg·kg^(−1) and a maximum value of 3080.0μg·kg^(−1).The mean daily exposure and 95th percentile daily exposure(by body weight)of DON from wheat flour and its products in Shanghai residents were 0.279μg·kg^(−1) and 1.146μg·kg,accounting for 27.9%and 114.6%of the daily tolerable intake of DON TDI,1μg·kg,respectively.The probability assessment results indicated that 6.1%of the whole population in Shanghai had DON exposure exceeding the TDI value.Among them,12.8%of the population aged 6 years old and below,16.4%of the population aged between 7 and 17 years old,3.9%of the population aged between 18 and 59 years old and 3.2%of the population aged 60 years old and above exceeded the TDI value for daily DON exposure through wheat flour and its products.[Conclusion]Certain populations in Shanghai may face certain health risks from daily DON intake wheat flour and its products.Special attention should be paid to the health risk of daily DON exposure through wheat flour and its products for individuals age below 18 years old.
