This study investigated the abundances and characteristics of microplastics in sediments and sandfish (Holothuria scabra) in Lampung and Sumbawa, Indonesia. Microplastics were found in 89.02% of all sandfish samples, with an average abundance of 2.01 ± 1.59 particles individual. The abundance of microplastics was 58.42 ± 24.33 particles kg in surface sediments. Furthermore, there was a positive relationship between the abundance of microplastics in sandfish and sediments. Fragments and fibers with small-sized microplastics (300-1000 μm) were the most abundant types found in sandfish and sediments. Fourier-transform infrared (FTIR) analysis showed that polyethylene (30.08%), polypropylene (30.08%), polyurethane (12.20%), and polyethylene terephthalate (8.94%) were the most abundant polymers in the samples. Our results strongly indicate that microplastics in Lampung and Sumbawa originate from the fragmentation of large plastics. Better solid waste management in Indonesia is needed to reduce plastic waste leakage, which could become microplastics.
本研究调查了印度尼西亚的楠榜和松巴哇海域沉积物和沙鱼（Holothuria scabra）中微塑料的丰度和特征。在所有沙鱼样本中，有 89.02%发现了微塑料，平均丰度为 2.01±1.59 个个体。表层沉积物中微塑料的丰度为 58.42±24.33 个颗粒/kg。此外，沙鱼和沉积物中微塑料的丰度之间存在正相关关系。沙鱼和沉积物中最丰富的微塑料类型是小尺寸（300-1000 μm）的碎片和纤维。傅里叶变换红外（FTIR）分析表明，样品中最丰富的聚合物为聚乙烯（30.08%）、聚丙烯（30.08%）、聚氨酯（12.20%）和聚对苯二甲酸乙二醇酯（8.94%）。我们的研究结果强烈表明，楠榜和松巴哇的微塑料来源于大塑料的破碎。印度尼西亚需要更好的固体废物管理，以减少塑料废物泄漏，这些废物可能会变成微塑料。
