Antimony (Sb) concentrations were measured in 10 brands of PET bottled drinking water available in supermarkets in China. To simulate general storage habits based on market research, these PET bottles with drinking water were stored for 4 weeks in a lab or a car trunk during the summer. Although the PET package material of brand A had the lowest Sb level (142.71 ± 29.81 μg/g), it showed a significant increase in Sb concentrations when stored in both the car trunk and the lab. There was significant release of Sb from the PET bottles into the water following 24 h of incubation at ≥ 40 °C (40, 50, 60, and 70 °C), especially at 70 °C. The potential health risk of Sb release from PET bottles was calculated based on daily intake values and determined to be acceptable for consumers under normal storage conditions.
在中国超市中，选取了 10 个品牌的 PET 瓶装饮用水，检测了其中的锑（Sb）浓度。为了根据市场研究模拟一般的储存习惯，在夏季，将这些装有饮用水的 PET 瓶在实验室或汽车后备箱中储存了 4 周。尽管品牌 A 的 PET 包装材料中的 Sb 含量最低（142.71 ± 29.81μg/g），但在汽车后备箱和实验室中储存时，Sb 浓度均显著增加。在 ≥40°C（40、50、60 和 70°C）下孵育 24 小时后，Sb 会从 PET 瓶中大量释放到水中，尤其是在 70°C 时。根据每日摄入量值，计算了从 PET 瓶中释放 Sb 的潜在健康风险，结果表明，在正常储存条件下，消费者可接受该风险。
