目的通过对烟台市居民饮料及白酒中邻苯二甲酸二丁酯(DBP)和邻苯二甲酸二(2-乙基己基)酯(DEHP)含量检测分析,计算烟台市居民膳食暴露风险并进行初步评价。方法在烟台市采集饮料和白酒样品共385份,采用气相色谱-质谱法测定饮料及白酒中DBP和DEHP的含量。利用饮料及白酒中DBP和DEHP的平均含量,结合居民平均食物消费量,计算烟台市居民经饮料和白酒摄入的DBP和DEHP水平,并分别与DBP和DEHP的每日可耐受摄入量(TDI)进行比较,初步评估烟台市居民经饮料及白酒摄入的DBP和DEHP的健康风险。结果饮料及白酒中DBP和DEHP含量范围分别为未检出(ND)~4.106和ND~3.285 mg/kg。烟台市居民饮料和白酒中DBP和DEHP暴露量分别为0.038和0.031μg/kg BW,远远低于健康指导值。结论烟台市居民经饮料及白酒摄入DBP和DEHP的健康风险较低。
Objective To calculate the risk of dietary exposure in Yantai residents through the detection and analysis of dibutyl phthalate (DBP) and di-2-ethylhexyl phthalate (DEHP) in Yantai residents’ drinks and liquor Preliminary evaluation. Methods A total of 385 samples of liquor and liquor were collected from Yantai City. The contents of DBP and DEHP in beverages and liquor were determined by gas chromatography - mass spectrometry. Based on the average contents of DBP and DEHP in beverages and liquor and the average food consumption of residents, the levels of DBP and DEHP in drinking and liquor in Yantai were calculated and compared with the daily tolerable intake of DBP and DEHP respectively (TDI) to assess the health risks of inhaling DBP and DEHP by drinking and liquor in Yantai City. Results The contents of DBP and DEHP in beverages and liquor were undetected (ND) ~ 4.106 and ND ~ 3.285 mg / kg, respectively. DBP and DEHP exposure of residents drinks and liquor in Yantai were 0.038 and 0.031 μg / kg BW respectively, far below the health guidance value. Conclusion The health risks of DBP and DEHP inhalation by drinks and liquor in Yantai residents are low.
