The extensive research on microplastics (MPs) in the last years has shown that it is not just an environmental problem anymore. As it can also be found in human food, it poses a potential risk for human health and food safety. Especially sea salt, which is produced by the evaporation of seawater, including its microplastic contamination, has been reported with different levels of MP contamination. Therefore, in this preliminary study, we investigated if different solar evaporation methods (traditional, geomembrane, and tunnel) influence the concentration of microplastic particles in sea salt production in Indonesia, one of the countries with the highest estimated level of plastic waste input into the ocean. The results show a significantly higher MP contamination in sea salt produced traditionally compared to the geomembrane and tunnel methods.

近年来，对微塑料（MPs）的广泛研究表明，它不再只是一个环境问题。正如在人类食品中也可以发现的那样，它对人类健康和食品安全构成了潜在的风险。据报道，特别是由海水蒸发产生的海盐，包括其微塑性污染，其MP污染程度不同。因此，在这项初步研究中，我们调查了不同的太阳蒸发方法（传统方法，土工膜和隧道方法）是否会影响印尼海盐生产中微塑料颗粒的浓度，印尼是向该国输入塑料废物的估计水平最高的国家之一海洋。结果表明，与土工膜和隧道方法相比，传统生产的海盐中的MP污染明显更高。
