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.
随着城市化和工业化的快速发展，一次性材料的消费量正在激增，这在日常生活中使用这些材料时可能不可避免地导致有毒有害物质的释放。本研究旨在估算渗滤液中铍（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）等元素的含量，并随后评估接触纸和塑料食品容器等一次性产品的健康风险。我们发现一次性食品容器在热水中会释放大量金属，金属浓度顺序为Zn > Ba > Fe > Mn > Ni > Cu > Sb > Cr > Se > Be > Pb > Co > V > Cd。此外，年轻人中金属的危害商（HQ）小于1，且按Sb > Fe > Cu > Be > Ni > Cr > Pb > Zn > Se > Cd > Ba > Mn > V > Co的顺序降低。此外，镍和铍的终生超额癌症风险（ELCR）结果表明，长期接触镍和铍可能存在不可忽视的致癌风险。这些发现表明，在高温环境下使用一次性食品容器的个体可能存在金属潜在健康风险。
