Journal Title: Shanghai Journal of Preventive Medicine - Year 2023, Vol 35, Issue 8
Abstract
ObjectiveTo investigate the pollution level of deoxynivalenol ï¼DONï¼ in wheat flour and its products sold in Shanghaiï¼ and to assess the health risks of DON exposure for residents in Shanghai who ingested DON from wheat flour and its products.MethodsRisk 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.ResultsThe overall detection rate of DON in wheat flour and its products was 77.3% ï¼1 041/1 347ï¼ï¼ with a mean concentration of 226.3 μg·kg-1ï¼ P50 of 130.0 μg·kg-1 and a maximum value of 3 080.0 μg·kg-1. The mean daily exposure and 95th percentile daily exposure ï¼by body weightï¼ of DON from wheat flour and its products in Shanghai residents were 0.279 μg·kg-1 and 1.146 μg·kgï¼ accounting for 27.9% and 114.6% of the daily tolerable intake of DON TDIï¼ 1 μg·kgï¼ respectively. The probability assessment results indicated that 6.1% of the whole population in Shanghai had DON exposure exceeding the TDI value. Among themï¼ 12.8% of the population aged 6 years old and belowï¼ 16.4% of the population aged between 7 and 17 years oldï¼ 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.ConclusionCertain 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 .
