<em>The file contains the raw data related to the manuscript: "Acetaldehyde in Polyethylene Terephthalate (PET) Bottled Water: Assessment and Mitigation of Health Risk for Consumers"</em> <strong>Abstract</strong>: This study was designed to investigate the levels of acetaldehyde residues in polyethylene terephthalate bottled water and its significance in terms of consumer health. We analyzed 104 samples collected throughout Italy, so as to be representative of the national market. Parameters such as CO₂ level, shelf life, weight of the empty bottle and distance from the production sites to the point of sale were also collected. Although the levels of acetaldehyde complied with the limits established by Italian legislation, they varied widely, with concentrations ranging from 0.41 to 76.2 µg/L. An assessment of safety for human health, using the margin of exposure approach, showed that the amount of acetaldehyde in bottled water is unlikely to be of any safety concern for human health. The acetaldehyde residues were mainly due to CO₂ levels which influence solubility of acetaldehyde in water. They are also related to the size of the bottle and the distance from the store, but not to the shelf life, at least for 40 days. The findings suggest some good practices for a better product from the point of view of public health, like polymer quality and limitation of transport distances. <strong>Funding</strong>: This research was funded by Mineracqua.本文件包含与论文《聚对苯二甲酸乙二醇酯（polyethylene terephthalate, PET）瓶装水中的乙醛（acetaldehyde）：消费者健康风险评估与防控》相关的原始数据。摘要：本研究旨在探究聚对苯二甲酸乙二醇酯瓶装水中的乙醛残留水平及其对消费者健康的影响。我们采集了104份覆盖意大利全国市场的瓶装水样本进行分析，同时收集了二氧化碳（CO₂）含量、保质期、空瓶重量以及生产地至销售点的距离等相关参数。尽管乙醛残留水平符合意大利立法规定的限值，但其浓度差异显著，波动范围介于0.41至76.2 μg/L之间。采用暴露边界（margin of exposure）法开展人体健康安全评估的结果显示，瓶装水中的乙醛含量不太可能对人体健康构成安全风险。乙醛残留主要受影响其在水中溶解度的二氧化碳含量影响，同时与瓶体尺寸及销售距离相关，但至少在40天保质期内与保质期无显著关联。本研究结果可为从公共卫生视角优化产品品质提供可行实践方向，例如提升聚合物质量、缩短运输距离。资助：本研究由Mineracqua资助。
