菲律宾目前是第三大塑料废物生产国，但在这个依赖渔业的发展中国家，几乎没有对海洋塑料污染进行过研究。这项研究是菲律宾中部尼格罗斯东部沿海地区一种重要的商业鱼类——兔鱼（Siganus fuscescens）摄入的微塑料的首次量化和表征。在所有地点中，来自人口稠密城市杜马格特的fuscesens肠道中微塑料聚合物类型的多样性最高。从杜马格特Silliman海滩的潮下沉积物样本中提取的微塑料颗粒主要是半合成微纤维（人造丝），可能来自服装和纺织品。然而，这些微塑料类型在鱼类的肠道中是不存在的，可能是由于它们的觅食栖息地的位置和特征不同。这项研究首次证实了菲律宾食用鱼类中微塑料的存在和多样性。
The Philippines is currently ranked as the third top producer of plastic wastes, yet little research has been conducted on marine plastic pollution in this fishery-dependent, developing country. This study is the first in the nation to quantify and characterize microplastics ingested by a commercially important fish, the rabbitfish (Siganus fuscescens), in the coastal areas of Negros Oriental, central Philippines. Across all sites, the diversity of microplastic polymer types was highest in the guts of S. fuscescens from Dumaguete, a densely populated city. Microplastic particles extracted from subtidal sediment samples from Silliman Beach in Dumaguete were dominated by semi-synthetic microfibers (rayon), probably from clothing and textiles. However, these microplastic types were absent in the guts of fish, likely due to the different location and character of their feeding habitats. This study confirms for the first time the presence and diversity of microplastics in an edible finfish in the Philippines.
