Ingestion and Depuration of Microplastics by a Planktivorous Coral Reef Fish, Pomacentrus amboinensis

This published research assesses microplastic ingestion and retention by coral reef fish, which are important information to assess ecological risks of this emergent contaminant to the Great Barrier Reef (GBR, Australia). Fish were collected with SCUBA and nets at Lizard Island (North GBR), exposed to microplastics under laboratory conditions at Lizard Island Research Station, and processed (i.e., gastrointestinal tract chemically digested, filtered and analysed under microscope) to assess microplastic ingestion at the Australian Institute of Marine Science (AIMS) in Townsville (Queensland, Australia). Data was statistically analysed using general linear model in R, kinetics model, one-way ANOVA and Tukey’s multiple comparisons tests.

本项已发表的研究聚焦珊瑚礁鱼类对微塑料（microplastic）的摄入与滞留情况，相关成果可为评估这一新兴污染物对澳大利亚大堡礁（Great Barrier Reef，简称GBR）的生态风险提供关键支撑。研究样本于大堡礁北部的蜥蜴岛（Lizard Island）通过水肺潜水（SCUBA）与网具采集，随后在蜥蜴岛研究站的实验室环境中进行微塑料暴露实验，后续于澳大利亚昆士兰州汤斯维尔的澳大利亚海洋科学研究所（Australian Institute of Marine Science，简称AIMS）完成样本处理与分析流程：具体为对鱼类胃肠道进行化学消解、过滤后置于显微镜下镜检，以此评估其微塑料摄入水平。本研究数据采用R语言中的广义线性模型、动力学模型、单因素方差分析（one-way ANOVA）以及Tukey多重比较检验（Tukey’s multiple comparisons tests）开展统计学分析。
