Marine microplastic (MP) pollution is becoming a serious problem and their potentially toxic effects on marine organisms have attracted much attention. Sea cucumber is very important for the safety and health of marine ecosystems. However, there have been relatively few studies on the effects of microplastic pollution on sea cucumbers at environmentally-related concentrations and under controlled conditions. Therefore, this study evaluated the effects of polyethylene terephthalate (PET) microplastics (particle sizes: 0.5-45 μm, 2-200 μm, and 20-300 μm; and three concentration levels for each particle size, approximately 10, 10, and 10 particles/kg) on the basic biological indicators, intestinal digestive enzymes, and intestinal flora of Apostichopus japonicus after a 28-day feeding experiment. This study showed that environmentally-related and high concentrations of microplastics had little effect on A. japonicus. This study provides valuable reference information about the effects of marine microplastic pollution on sea cucumbers.
海洋微塑料（MP）污染正成为一个严重的问题，其对海洋生物的潜在毒性作用引起了广泛关注。海参对海洋生态系统的安全和健康非常重要。然而，在与环境相关的浓度和受控条件下，关于微塑料污染对海参的影响的研究相对较少。因此，本研究评估了聚对苯二甲酸乙二醇酯（PET）微塑料（粒径：0.5-45μm、2-200μm 和 20-300μm；每种粒径有三个浓度水平，约为 10、10 和 10 个/千克）对 28 天喂养实验后刺参基本生物学指标、肠道消化酶和肠道菌群的影响。本研究表明，与环境相关的和高浓度的微塑料对刺参的影响很小。本研究为海洋微塑料污染对海参的影响提供了有价值的参考信息。
