Phthalate esters (PAEs) have attracted much attention because of their ubiquity and toxicity. However, previous studies mainly focused on the occurrence of PAEs controlled by the Environmental Protection Agency and neglected most uncontrolled PAEs. In this study, the occurrence of 21 PAEs, including 6 controlled and 15 uncontrolled PAEs, was investigated in polyethylene terephthalate (PET)-bottled drinking water samples purchased from markets in Beijing. Seventeen PAEs were detected in all samples, with dibutyl phthalate, diisobutyl phthalate, and dimethyl phthalate as the predominant compounds. Correlation analysis suggested that PET bottles might be one of the potential sources of PAEs in PET-bottled drinking water. The human health risks assessments indicated little or no risks from four controlled PAEs in bottled water. In comparison, the risks of uncontrolled PAEs should be of greater concern for their ubiquities in bottled drinking water.
邻苯二甲酸酯（PAEs）因其无处不在和毒性而备受关注。然而，以往的研究主要集中在由环境保护局控制的PAEs的存在情况，而忽略了大多数不受控制的PAEs。在本研究中，对从北京市场购买的聚对苯二甲酸乙二酯（PET）瓶装饮用水样品中21种PAEs的存在情况进行了调查，其中包括6种受控PAEs和15种不受控PAEs。在所有样品中检测到17种PAEs，其中邻苯二甲酸二丁酯、邻苯二甲酸二异丁酯和邻苯二甲酸二甲酯为主要化合物。相关性分析表明，PET瓶可能是PET瓶装饮用水中PAEs的潜在来源之一。人体健康风险评估表明，瓶装水中四种受控PAEs的风险很小或没有风险。相比之下，不受控PAEs的风险因其在瓶装饮用水中无处不在而应受到更大关注。
