| Abstract: |
| The dietary exposure and risk of aflatoxin B1 (AFB1) in peanut oil of small workshops in Yulin City, Guangxi Province was assessed and some requirements were put forward. According to regions, genders, urban and rural and ages/urban and rural/genders were divided into groups. Combined with the B dietary pattern data of Guangxi residents, the exposure amount in the Point Estimate Model and the MOE by BMDL10 400 ng/(kg·d) were calculated. The results showed that the detection rate of AFB1 in peanut oil of small workshops in Yulin, Guangxi was 59% and the exceeding standard rate was 18.6%. The content range of AFB1 was between 0.05 μg/kg to 243.00 μg/kg. The average content was 16.91 μg/kg, which was significantly higher than that of the packaging peanut oil (P<0.01).The average exposure amount of AFB1 in the peanut oil of small workshops in the city was 7.76 ng/(kg·d) and the MOE was 52. The average daily dietary exposure MOE of each group was between 200 to 25. According to the MOE of each group, it was found that the risk of XY (MOE 27) and BL (MOE 37) in six counties and cities were the highest; villages (MOE 46) > cities (MOE 73); women (MOE 49) > men (MOE 55); the residents at the age between 6 and 11 (MOE 41-25) > the residents at the age between 12 and 14 (MOE 70-37) > the residents over the age of 15 (MOE 85-44). There was potentially high health risk for the intake of AFB1 from the peanut oil of small workshops in the city. It should attract the great public health attention. |
