微塑料在世界各地的海洋中都有发现。我们假设海盐可能含有微塑料，因为它们直接由海水提供。为了验证我们的假设，我们从中国各地的超市收集了15个品牌的海盐、湖盐和岩盐/井盐。海盐中的微塑料含量为550-681颗粒/kg，湖盐中为43-364颗粒/kg，岩盐/井盐中为7-204颗粒/kg。在海盐中，碎片和纤维是与丸状和片状相比的普遍类型的颗粒。测量小于200 ism的微塑料代表了大多数颗粒，占总微塑料的SS%，最常见的微塑料是聚对苯二甲酸乙二醇酯，其次是海盐中的聚乙烯和玻璃纸。海盐中微塑料的丰度明显高于湖盐和岩盐/井盐。这一结果表明，海盐等海产品受到微塑料污染。据我们所知，这是第一份关于非生物海产品中微塑料污染的报告。
Microplastics have been found in seas all over the world. We hypothesize that sea salts might contain microplastics, because they are directly supplied by seawater. To test our hypothesis, we collected 15 brands of sea salts, lake salts, and rock/well salts from supermarkets throughout China. The microplastics content was 550-681 particles/kg in sea salts, 43-364 particles/kg in lake salts, and 7-204 particles/kg in rock/well salts. In sea salts, fragments and fibers were the prevalent types of particles compared with pellets and sheets. Microplastics measuring less than 200 ism represented the majority of the particles, accounting for SS% of the total microplastics, and the most common microplastics were polyethylene terephthalate, followed by polyethylene and cellophane in sea salts. The abundance of microplastics in sea salts was significantly higher than that in lake salts and rock/well salts. This result indicates that sea products, such as sea salts, are contaminated by microplastics. To the best of our knowledge, this is the first report on microplastic pollution in abiotic sea products.
