Determining the amount of microplastics (MPs) in food is key to clarifying their potential toxicity to humans. Here, we collected canned, instant, and salt-dried sea cucumbers Apostichopus japonicus, the most valued sea cucumbers, from Chinese markets to determine their content of MPs. Sea cucumbers contained MPs in the range of 0-4 MP individual, an average of 1.44 MP individual, and 0.081 MP g. Accordingly, consuming 3 g of sea cucumbers could result in an exposure risk of an average of 0.51 MPs, 0.135 MPs, and 0.078 MPs day for canned, instant, and salt-dried sea cucumbers, respectively. MPs were in size range of 12-575 μm, and fibrous shape was dominant. Furthermore, among the five polymers identified, polypropylene showed the highest energy binding with two catalysts engaged in organic chemical oxidation. This study extends the knowledge regarding MPs occurrence in food and provides a theoretical basis for MPs toxicity in humans.
确定食品中微塑料（MPs）的含量是澄清其对人类潜在毒性的关键。在这里，我们从中国市场收集了罐装、速食和盐干海参（Apostichopus japonicus），这是最有价值的海参，以确定它们的 MPs 含量。海参中的 MPs 含量范围为 0-4 个 MPs 个体，平均 1.44 个 MPs 个体，0.081 个 MPs g。因此，食用 3 克海参可能会导致摄入的 MPs 分别为平均 0.51 MPs、0.135 MPs 和 0.078 MPs 天，对于罐装、速食和盐干海参而言。MPs 的尺寸范围为 12-575μm，纤维形状占主导地位。此外，在所鉴定的五种聚合物中，聚丙烯与两种参与有机化学氧化的催化剂表现出最高的能量结合。本研究扩展了关于 MPs 在食品中存在的知识，并为 MPs 在人类中的毒性提供了理论基础。
