This study investigates the contamination of phthalate esters (PAEs) and microplastics (MPs) in yellowfin tuna (Thunnus albacares) collected from the southern coast of Kaohsiung, Taiwan. Results revealed significantly higher PAE concentrations in red muscle tissue (2595-72,734 ng/g ww), with DiNP, DnBP, and DEHP as the dominant compounds, compared to lower levels in white muscle (271.98-811.49 ng/g ww). Specifically, the stomach (92 particles) contained a higher number of MP particles compared to the gill (56 particles). Fibrous rayon dominated in the gills, likely due to water filtration, while polypropylene and polyolefin fragments were prevalent in the stomach, suggesting ingestion of plastic debris. Most MPs measured 1-2 mm in size and were blue or transparent, indicating textile and film-based sources. Principal component analysis showed that bioaccumulation patterns were associated with the hydrophobicity and molecular weight of PAEs. These highlight improved marine pollution controls to safeguard ecological and human health.
本研究调查了从台湾高雄南部海岸采集的黄鳍金枪鱼（Thunnus albacares）中邻苯二甲酸酯（PAEs）和微塑料（MPs）的污染情况。结果显示，红肌组织中的PAE浓度显著更高（2595 - 72,734纳克/克湿重），以邻苯二甲酸二异壬酯（DiNP）、邻苯二甲酸二正丁酯（DnBP）和邻苯二甲酸二（2-乙基己基）酯（DEHP）为主要化合物，而白肌中的浓度较低（271.98 - 811.49纳克/克湿重）。具体而言，胃中（92个颗粒）的MP颗粒数量高于鳃中（56个颗粒）。鳃中以纤维状人造丝为主，这可能是由于水过滤作用，而胃中聚丙烯和聚烯烃碎片较为普遍，表明摄入了塑料碎片。大多数MP的尺寸为1 - 2毫米，呈蓝色或透明，表明其来源为纺织品和薄膜。主成分分析表明，生物累积模式与PAEs的疏水性和分子量有关。这些结果凸显了加强海洋污染控制以保护生态和人类健康的必要性。
