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.

2: おおむね順調に進展している

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.

次年度使用額が生じた理由

The remaining budget will be moved for the next FY to end the laboratory improvement to accomplish sample processing during the last year of the project
