We surveyed the abundance and accumulation patterns of mesoplastic marine debris (5-25mm) on 20 beaches in Korea. The mean abundance of it was 13.2items/m, and the mean weight was 1.5g/m. Hard plastic and Styrofoam were the dominant types. The proportions of hard plastic and Styrofoam were highly variable among the beaches, each accounting for 0-100% of the total debris on a given beach with 32% and 48.5% (by number) on average, respectively. Relatively lower abundances of mesoplastic marine debris compared with our previous studies were likely due by differences of the sampling areas within the beach. The samples of this research were selected from backshore, middle line, and water edge whereas they were selected from high strandline and backshore in our previous studies. It should be considered when discussing the level of mesoplastic marine debris.
我们调查了韩国 20 个海滩上中塑海洋碎片（5-25 毫米）的丰度和积累模式。其平均丰度为 13.2 个/米，平均重量为 1.5 克/米。硬塑料和泡沫塑料是主要类型。硬塑料和泡沫塑料在各海滩之间的比例差异很大，在给定的海滩上，每种类型的碎片分别占总碎片的 0-100%，平均分别占 32%和 48.5%（按数量计算）。与我们之前的研究相比，中塑海洋碎片的丰度相对较低，这可能是由于海滩内采样区域的差异所致。本研究的样本选自后滨、中线和水缘，而我们之前的研究则选自高滩线和后滨。在讨论中塑海洋碎片的水平时应考虑到这一点。
