Microplastics (MPs, <5 mm) accumulate in marine environments, impacting marine organism health. This study examined MPs in sediment and two pelagic fish species (S. maderensis and I. africana) in Ghana's Gulf of Guinea. The study found an average concentration of 0.144 ± 0.061 items/g (dry weight) in the sediment, with pellets and transparent particles being the most common types. The concentration of MPs in contaminated fish ranged from 8.35 to 20.95, with fibers and pellets being the most abundant plastic-type in fish. Individual organ concentrations of MPs varied. In fish gills, concentrations ranged from 1 to 26 MPs/individual for I. africana and 1-22 MPs/individual for S. maderensis. Concentrations in the fish guts ranged from 1 to 29 MPs/individual for I. africana and 2-24 MPs/individual for S. maderensis. Results from the study highlight the importance of both gills and guts as important organs in terms of microplastic contamination and emphasize the significance of monitoring microplastic contamination in fish gills and guts. This offers valuable insight into the impact of MPs on the marine environment and human health.
微塑料（MPs，<5 毫米）在海洋环境中积累，影响海洋生物健康。本研究调查了加纳几内亚湾沉积物和两种洄游鱼类（塞内加耳拟沙丁鱼和非洲鲫）中的 MPs。研究发现，沉积物中的 MPs 平均浓度为 0.144±0.061 个/克（干重），其中颗粒状和透明颗粒状是最常见的类型。受污染鱼类中的 MPs 浓度范围为 8.35 至 20.95，纤维状和颗粒状是鱼类中最丰富的塑料类型。个体器官中 MPs 的浓度存在差异。在鱼类鳃中，非洲鲫的 MPs 浓度范围为 1 至 26 个/个体，塞内加耳拟沙丁鱼的 MPs 浓度范围为 1 至 22 个/个体。鱼类肠道中 MPs 的浓度范围为 1 至 29 个/个体，非洲鲫的 MPs 浓度范围为 2 至 24 个/个体，塞内加耳拟沙丁鱼的 MPs 浓度范围为 2 至 24 个/个体。研究结果强调了鱼类鳃和肠道作为微塑料污染重要器官的重要性，并强调了监测鱼类鳃和肠道中微塑料污染的重要性。这为 MPs 对海洋环境和人类健康的影响提供了有价值的见解。
