[背景]邻苯二甲酸酯存在于许多个人护理和工业产品中,但以前没有报道表明其存在于美国食品中。邻苯二甲酸盐是广泛存在的人工合成的化合物,因此很难测量其在食品中的痕量水平。邻苯二甲酸酯与内分泌紊乱和发育改变相关联。[目的]首次报告美国食品中邻苯二甲酸酯的浓度,具体而言是在纽约州奥尔巴尼购买的72份食物样本中9种邻苯二甲酸酯类物质的水平,并将这些结果与其他国家的相关研究进行比较,估计膳食邻苯二甲酸盐的摄入量。[方法]采用购自纽约州超市经常食用的食物作为方便抽样样本。使用气相色谱-质谱法分析这些食物。用食物食用率和该种食物中邻苯二甲酸盐浓度的乘积来估计邻苯二甲酸盐膳食摄入量。[结果]食物中各邻苯二甲酸酯类物质的检出率范围从邻苯二甲酸二环己酯(d.HP)的6%到邻苯二甲酸二-2-乙基己酯(d.HP)的74%。在除牛肉以外的所有食品中,d.HP是浓度最高的邻苯二甲酸酯[在牛肉中,邻苯二甲酸二正辛酯(d.OP)是浓度最高的邻苯二甲酸酯],猪肉中的平均浓度估计值在所有食物组中最高(平均300ng/g,最大为1158ng/g)。成人摄入估计平均值范围从0.004μg(/kg.d.邻苯二甲酸二甲酯(d.P)至0.673μg(/kg.d.d.HP。[结论]邻苯二甲酸酯广泛存在于美国食物中,虽然这项研究中的邻苯二甲酸酯个体摄入估计值比美国环境保护局的参考剂量低一个数量级,但对邻苯二甲酸酯的累积暴露仍需要关注,同时需要进行更具代表性的美国食品调查。
