We appreciate the insightful comments provided by Sun et al. (1) regarding our paper on the assessment of microplastics and nanoplastics (MNPs) released from plastic containers and food pouches commonly used in baby food preparation and storage. (2) Our study revealed that microwave heating resulted in the highest release of MNPs into food compared to other usage scenarios, such as refrigeration or room temperature storage. Sun et al. (1) raised a valid concern regarding the potential misinterpretation of our findings, particularly concerning the safety of microwave heating for food. They conducted a comparative analysis between the release of MNPs from microwave heating and water bath heating, revealing comparable levels of release in both methods. Their experiments not only replicate our findings by demonstrating a similar release of MNPs following microwave heating but also provide crucial data that complements our study. While our research highlighted the role of temperature increase in enhancing the release of MNPs following microwave heating, we did not provide experimental data to support this claim. Sun et al.’s (1) findings effectively fill this gap, offering concrete evidence that supports and further elucidates the mechanisms we proposed. We both concur that the simultaneous temperature increase in both the container material and the food as a key contributing factor to the release of MNPs. It is noteworthy that Sun et al. explicitly state that their results are not contradictory to ours but rather provide additional support and clarity on why microwave heating leads to a higher release of MNPs compared to other conditions. It is important to underscore that microwave heating is a prevalent method for heating food, often involving microwavable plastic containers. While the primary driver behind the enhanced release of MNPs is the temperature increase, it is imperative to caution individuals about the potential risks associated with using microwaves to heat food in plastic containers, given the inevitable rise in temperature during the process. This precautionary approach is essential to ensure consumer safety and well-being. This article references 2 other publications. This article has not yet been cited by other publications.

反驳“评估塑料容器和可重复使用食品袋中微塑料和纳米塑料的释放：对人类健康的影响”的信函


我们感谢 Sun 等人提供的富有洞察力的评论。 (1) 关于我们关于评估婴儿食品制备和储存中常用的塑料容器和食品袋中释放的微塑料和纳米塑料 (MNP) 的论文。 (2) 我们的研究表明，与其他使用场景（例如冷藏或室温储存）相比，微波加热导致食品中 MNP 的释放量最高。孙等人。 (1) 对我们的研究结果的潜在误解提出了合理的担忧，特别是关于微波加热食品的安全性。他们对微波加热和水浴加热的 MNP 释放进行了比较分析，揭示了两种方法的释放水平相当。他们的实验不仅通过证明微波加热后 MNP 的类似释放来复制我们的发现，而且还提供了补充我们研究的重要数据。虽然我们的研究强调了微波加热后温度升高在增强 MNP 释放方面的作用，但我们没有提供实验数据来支持这一说法。 Sun等人（1）的研究结果有效地填补了这一空白，提供了支持并进一步阐明我们提出的机制的具体证据。我们都同意容器材料和食品的温度同时升高是 MNP 释放的关键因素。值得注意的是，Sun 等人。明确指出他们的结果与我们的结果并不矛盾，而是提供了额外的支持和澄清为什么微波加热会导致与其他条件相比更高的 MNP 释放。 需要强调的是，微波加热是加热食物的普遍方法，通常涉及微波塑料容器。虽然 MNP 释放增加的主要驱动因素是温度升高，但必须提醒个人注意使用微波炉加热塑料容器中的食物的潜在风险，因为在此过程中温度不可避免地升高。这种预防措施对于确保消费者的安全和福祉至关重要。本文引用了另外 2 篇出版物。这篇文章尚未被其他出版物引用。本文引用了另外 2 篇出版物。
