随着城市化和工业化的快速发展，一次性材料的消耗正在蓬勃发展，这在日常生活中使用它们时不可避免地会导致有毒有害物质的释放。本研究旨在估计浸出液中的元素水平，如铍（Be）、钒（V）、锌（Zn）、锰（Mn）、镉（Cd）、铬（Cr）、镍（Ni）、钴（Co）、锑（Sb）、钡（Ba）、铅（Pb）、铁（Fe）、铜（Cu）和硒（Se），并随后评估接触这些一次性产品（如纸质和塑料餐盒）的健康风险。我们发现大量金属从一次性餐盒中在热水中释放，在金属浓度方面的顺序是Zn> Ba> Fe> Mn> Ni> Cu> Sb> Cr> Se> Be> Pb> Co> V> Cd。此外，青年成年人中金属的危险系数（HQ）小于1，顺序是Sb> Fe> Cu> Be> Ni> Cr> Pb> Zn> Se> Cd> Ba> Mn> V> Co。此外，Ni和Be的超额寿命癌症风险（ELCR）结果表明，长期暴露于Ni和Be可能具有不可忽略的致癌风险。这些发现表明，在高温环境下使用一次性餐盒的个人可能存在金属的潜在健康风险。 版权所有©2023作者。由Elsevier Inc.出版。保留所有权利。

The consumption of disposable materials is booming with the rapid development of urbanization and industrialization, which may inevitably cause the release of toxic and harmful substances during use of them in daily life. This study was to estimate element levels such as Beryllium (Be), Vanadium (V), Zinc (Zn), Manganese (Mn), Cadmium (Cd), Chromium (Cr), Nickel (Ni), Cobalt (Co), Antimony (Sb), Barium (Ba), Lead (Pb), Iron (Fe), Copper (Cu), and Selenium (Se) in leachate and subsequently assess the health risk of exposure to those disposable products such as paper and plastic food containers. We found that a large amount of metals was released from disposable food containers in hot water, and the order of metal concentration is Zn > Ba > Fe > Mn > Ni > Cu > Sb > Cr > Se > Be > Pb > Co > V > Cd. Additionally, the hazard quotient (HQ) of metals in young adults were less than 1, and were decreased in the order of Sb > Fe > Cu > Be > Ni > Cr > Pb > Zn > Se > Cd > Ba > Mn > V > Co. Furthermore, the excess lifetime cancer risk (ELCR) results of Ni and Be indicated that chronic exposure to Ni and Be may have a non-negligible carcinogenic risk. These findings suggest that potential health risk of metals may exist for the individuals to use disposable food containers under high temperature environment.Copyright © 2023 The Authors.
