| 研究開始時の研究の概要 |
One way to reduce plastic pollution is by detecting main hotspots and reducing their primary sources. More studies are needed to improve our understanding of microplastics' presence and impact on marine systems. Therefore, this study aims to understand microplastic abundance and characteristics in the Chao Phraya estuary. Also, to determine the exposure of zooplankton organisms to microplastic ingestion and determine the exposition risk of their predators, including the effects of rain and tidal currents

| 研究実績の概要 |
In the project's inaugural year, I conducted an oceanographic survey across the Gulf of Thailand during both wet and dry seasons, encompassing 12 sampling sites. This survey was developed in colaboration with SEAFDEC from Thailand. The objective was to assess the presence of microplastics in the water column and their ingestion by the zooplankton community. A total of 24 zooplankton and water samples were collected for each season, yielding 48 samples in total. Additionally, I actively engaged in collaborative international initiatives such as MOEJ and GPML-UNEP projects, aimed at standardizing microplastic analysis methodologies globally. This collaborative effort facilitated the development of standardized protocols, ensuring uniformity and comparability of research findings across diverse geographical regions.

理由
The project is progressing well towards its objectives. So far, 50% of the collected samples have undergone pre-processing to identify microplastic composition in water and zooplankton. This involved analyzing zooplankton species composition and prepare individuals for microplastic isolation. Given the extensive sampling efforts across 2 seasons, this progress is commendable.

| 今後の研究の推進方策 |
Future dissemination efforts for this research project entail utilizing preliminary findings to draft two manuscripts. Furthermore, I aim to showcase these results at the forthcoming MICRO 2024 conference in Spain, highlighting the valuable insights gleaned from the research.
