The present study investigated the microplastics (MPs) contamination in the gastrointestinal (GI) tract, gills and muscle of the Mozambique tilapia, Oreochromis mossambicus sampled from the Selvampathy Lake of Coimbatore, Tamil Nadu. MPs abundance was found in 10 to 28, 8 to 27, and 4 to 12 particles and their size ranged between 4.4 and 210, 4.6 to 180, and 4.5 to 194 μm in the GI tract, gills and muscle, respectively. MPs were dominantly shaped as fibres (95%) and fragments (5%) with the following colour pattern of blue > black > pink > transparent > and others. Extracted MPs polymer nature were polyethylene (54%), polyamide (38%) and polypropylene (8%). The present study reveals that the edible fish O. mossambicus had MPs that can be transferred to consumers. Moreover, urban discharges, including domestic wastes, agricultural and rainwater runoff, might be possible MPs sources to the studied wetland.

本研究调查了从泰米尔纳德邦哥印拜陀 Selvampathy 湖取样的莫桑比克罗非鱼Oreochromis mossambicus的胃肠道 (GI)、鳃和肌肉中的微塑料 (MP) 污染情况。在胃肠道、鳃和肌肉中发现 MPs 丰度为 10 至 28、8 至 27 和 4 至 12 个颗粒，其大小范围分别为 4.4 至 210、4.6 至 180 和 4.5 至 194 μm。MP 的形状主要为纤维（95%）和碎片（5%），颜色模式为蓝色>黑色>粉色>透明>等。提取的MPs聚合物性质为聚乙烯(54%)、聚酰胺(38%)和聚丙烯(8%)。目前的研究表明，食用鱼莫桑比克含有可以转移给消费者的 MP。此外，城市排放物，包括生活垃圾、农业和雨水径流，可能是所研究湿地的 MP 来源。
