自从海盐中检测出微塑料以来，其健康风险已引起广泛的关注。文章综述了海盐微塑料的来源、分布、物理特性、化学组成、检测技术以及相关研究进展，并对未来的研究进行展望。研究表明，海盐中微塑料可能来自海水及加工过程，产自亚洲的海盐中微塑料丰度相对较高。检出的微塑料尺寸大多小于500 μm，其主要成分为聚对苯二甲酸乙二醇酯(PET)、聚乙烯(PE)和聚丙烯(PP)。海盐微塑料检测技术主要有光学显微镜法、光谱分析法、热分析法等。

Since microplastics are found in sea salt, their health risks have attracted widespread attention. This paper reviews the sources, distribution, physical properties, chemical composition, detection techniques and related research advances of microplastics in sea salt, and provides perspectives on future studies. The microplastics in sea salt may come from seawater and processing, and the
abundance of microplastics in the sea salt produced in Asia is relatively high. The sizes of detected microplastics are mostly less than 500 μm, and polyethylene terephthalate (PET), polyethylene (PE), and polypropylene (PP) are the main components. The detection techniques of microplastics in sea salt mainly include optical microscopy, spectral analysis, and thermal analysis.
