Association between Phthalate Exposure and the Use of Plastic Containers in Shanghai Adults

Objective Consuming phthalates may be due to the presence of food contact materials, such as plastic containers. In this study, we investigated the association between plastic container use and phthalate exposure in 2,140 Shanghai adults. Methods Participants completed a questionnaire on the frequency of using plastic containers in different scenarios in the previous year （e.g., daily, weekly） and on the consumption of plastic-packaged foods in the previous three days （yes or no）. Urinary phthalate metabolites were used to assess the association between phthalate exposure and the use of plastic containers. Results The metabolites of di-（2-ethylhexyl） phthalate （DEHP） were the most frequently detected in urine. The results revealed that phthalate exposure was associated with consumption of plastic-packaged breakfast or processed food items in the previous three days. The consumption of these two food items had strong synergistic effects on increasing urinary concentrations of most phthalate metabolites. Conclusion Our results of plastic-packaged breakfast and processed food may be explained by the use of flexible plastic containers, indicating the importance of risk assessment for the application of flexible plastic containers.

端视ICP-AES法测定食品用塑料包装容器在四种食品模拟物中有害元素迁移量

建立了端视电感耦合等离子体原子发射光谱(ICP-AES)法测定食品用塑料包装容器在4种食品模拟物中有害元素铅、镉、铬、砷、锑和锗迁移量的分析方法。研究了不同食品模拟物试液的处理方法以及仪器工作参数对铅、镉、铬、砷、锑和锗测定信号的影响,消除了乙醇基质的严重抑制干扰,并优化了ICP-AES测定条件。铅、镉、铬、砷、锑和锗的检出限分别为0.0025、0.00023、0.00016、0.0033、0.0032、0.0030mg/L,测定低限:以蒸馏水、3%乙酸、10%乙醇作食品模拟物时分别为0.010、0.0010、0.0010、0.010、0.010、0.010mg/L;以精制橄榄油作食品模拟物时分别为0.020、0.0020、0.0020、0.020、0.020、0.020mg/L。加标回收率在92.0%～98.8%,相对标准偏差在1.69%～7.64%(n=8)。方法灵敏、简便、快速、准确,适用于进出口食品用塑料包装容器中有害元素迁移量的快速测定。
