烟台市居民经饮料和白酒摄入邻苯二甲酸二(2-乙基己基)酯和邻苯二甲酸二丁酯的风险评估

Risk assessment of DEHP and DBP in beverage and white spirits of residents in Yantai City

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 analyze the content of dibutyl phthalate and bis（2-ethylhexyl） phthalate in beverage and white spirits,and assess the risk of dietary exposure of residents in Yantai City.Methods A total of 385 samples were collected,the determination and quantification were performed by gas chromatography-mass spectrometer（GC-MS） in selected ion monitoring（SIM） mode.The dibutyl phthalate and bis（2-ethylhexyl） phthalate exposure was estimated by the food consumption data.The health risk was assessed by comparing the exposure with tolerable daily intake（TDI）.Results The concentration of dibutyl phthalate and bis（2-ethylhexyl） phthalate was ND-4.106 and ND-3.285 mg/kg.In accordance with the mean value of food consumption estimates,the dibutyl phthalate and bis（2-ethylhexyl） phthalate exposure of local residents were 0.038 and 0.031 μg/kg BW,which were below the TDI.Conclusion The risk of dibutyl phthalate and bis（2-ethylhexyl） phthalate was low from beverage and white spirits for Yantai City residents.
