Foodstuffs may be contaminated by organophosphate esters (OPEs) and become an important source of human exposure since OPEs are ubiquitous in the environment. In the present study, 10 OPEs were analyzed in various food matrices collected from a city in Eastern China including chicken, pork, fishes, vegetables, tofu, eggs, milk and cereals. The concentrations of ΣOPEs ranged from 1.1 to 9.6 ng g fresh weight (fw) in the foodstuffs. Cereals had the highest residual level of total OPEs with a mean value of 5.7 ng g fw. Tris(2-ethylhexyl) phosphate was detected in all foodstuff samples and showed the highest median residual concentration of 1.3 ng g fw among the OPE analogs. The daily dietary intake of OPEs was calculated as 3.6 and 2.4 μg d for adults and children. Cereals were identified as the major contributor to the total OPEs among different types of foodstuffs. Preliminary exposure assessment revealed that the current non-cancer health risks of OPEs via dietary intake were in the range of 10-10, indicating low risk levels. Moreover, the hazard index of OPEs indicated that the risk for children (3 × 10) was higher than adults (2 × 10).
食品可能会被有机磷酸酯（OPEs）污染，成为人类暴露的重要来源，因为 OPEs 在环境中无处不在。在本研究中，分析了来自中国东部某城市的鸡肉、猪肉、鱼类、蔬菜、豆腐、鸡蛋、牛奶和谷物等各种食品基质中的 10 种 OPEs。食品中ΣOPEs 的浓度范围为 1.1 至 9.6ng/g 鲜重（fw）。谷物的总 OPEs 残留水平最高，平均值为 5.7ng/g fw。所有食品样本中均检测到三（2-乙基己基）磷酸酯，在 OPE 类似物中表现出最高的中位数残留浓度 1.3ng/g fw。计算得出 OPEs 的每日膳食摄入量为成年人和儿童分别为 3.6 和 2.4μg/d。谷物被确定为不同类型食品中总 OPEs 的主要贡献者。初步暴露评估显示，通过饮食摄入 OPEs 的当前非癌症健康风险处于 10-10 范围内，表明风险水平较低。此外，OPEs 的危害指数表明，儿童（3×10）的风险高于成年人（2×10）。
