Ingestion and retention of biodegradable vs. non-biodegradable microplastics in a tropical coral reef fish: The role of chemical and physical characteristics

This dataset contains experimental measurements from a study investigating the ingestion and retention of biodegradable and non-biodegradable microplastics (MPs) in juvenile tropical reef fish, Acanthochromis polyacanthus. The study assessed how polymer type (polystyrene vs. polycaprolactone), particle shape (films vs. fragments), size (100–400 μm), and colour (transparent vs. blue) influence MP ingestion preferences and gastrointestinal transit time (GTT).

Data include:
Individual fish identifiers and characteristics (e.g., weight, size)
Type, shape, size, and colour of MPs offered
Quantity and type of MPs ingested per fish after 2 h exposure
Gastrointestinal transit time and depuration rate of MPs over 72 h
Observed ingestion patterns and depuration dynamics for each polymer type
The dataset supports the findings reported in: “Ingestion and retention of biodegradable vs. non-biodegradable microplastics in a tropical coral reef fish: The role of chemical and physical characteristics”, Marine Pollution Bulletin, MPB 119346.

These data provide detailed information for understanding how polymer-specific physical traits influence ingestion and retention in reef fish, offering a valuable resource for replication studies, meta-analyses, and further research on microplastic pollution and the evaluation of biodegradable plastics.

本数据集包含一项研究的实验测量数据，该研究聚焦热带礁栖幼鱼棘雀鲷（Acanthochromis polyacanthus）对可生物降解与不可生物降解微塑料（microplastics, MPs）的摄入与留存情况。该研究评估了聚合物类型（聚苯乙烯与聚己内酯）、颗粒形状（薄膜与碎片）、粒径（100–400 μm）以及颜色（透明与蓝色）对微塑料摄入偏好及胃肠道转运时间（gastrointestinal transit time, GTT）的影响。
数据集涵盖以下内容：
1. 单条鱼类的识别标识与生长特征（如体重、体长）
2. 投喂微塑料的类型、形状、粒径与颜色
3. 暴露2小时后每条鱼摄入的微塑料数量与种类
4. 72小时内微塑料的胃肠道转运时间与净化速率
5. 不同聚合物类型下观测到的摄入模式与净化动态
本数据集支撑下述已发表研究的结论："热带珊瑚礁鱼类对可生物降解与不可生物降解微塑料的摄入与留存：化学与物理特性的作用", 《海洋污染通报（Marine Pollution Bulletin）》，编号MPB 119346。
本数据集可为解析聚合物特有物理性状如何影响礁栖鱼类的微塑料摄入与留存过程提供详实数据支撑，同时为重复研究、元分析（meta-analyses）以及微塑料污染相关后续研究与可生物降解塑料的评估工作提供极具价值的研究资源。
