研究人员在日本冲绳岛海滩发现了一种新型塑料污染现象，被称为"塑料珊瑚"，这是熔融的塑料聚合物与死亡珊瑚骨骼不可分离地混合形成的混合物1。这项由冲绳科学技术研究所和琉球大学共同进行的研究已发表在《海洋污染通报》上，发表日期为2026年9月18日1。发现的标本尺寸为20-30毫米宽1，第一作者为Dr. Ifenna Ilechukwu，资深作者为Professor James D. Reimer1。
这一发现揭示了塑料污染对已受气候变化威胁的珊瑚礁生态系统的长期影响1。研究指出，塑料是世界第三广泛制造的材料，仅次于水泥和钢铁1。聚合物中的化学物质会破坏珊瑚繁殖，而塑料片已被发现携带珊瑚病原体并通过海洋食物链传播1。
Scientists at the Okinawa Institute of Science and Technology (OIST) and the University of the Ryukyus have identified a previously undocumented type of marine plastic pollution on beaches in Okinawa, Japan.1 The phenomenon, termed "plasticorals," consists of melted plastic polymers that have become inextricably bonded with the skeletal remains of dead coral, creating a hybrid composite material measuring between 20 to 30 millimeters in width.1 The research, led by Dr. Ifenna Ilechukwu and senior researcher Professor James D. Reimer, was published in Marine Pollution Bulletin on September 18, 2026.1
The discovery underscores the escalating threat that plastic pollution poses to coral reef ecosystems already stressed by climate change.1 Plastics represent the world's third most widely manufactured material, surpassed only by cement and steel,1 and the chemical compounds within these polymers actively disrupt coral reproduction.1 Additionally, plastic fragments have been found to carry coral pathogens and transmit disease through marine food chains.1
