  • Understanding the mechanisms of microplastic formation

    Researchers / Institutional Affiliations Principal Investigator Collaborators Timeline Underway since March 2019 Additional information This study aimed to clarify the kinetic mechanisms by which secondary microplastics are generated from plastics, using the principles of polymer science and engineering. There are three main areas of focus: a detailed analysis of microplastics collected in the environment, along […] Read more

  • Modeling the vector effect of microplastics in the environment

    Researchers / Institutional Affiliations Principal Investigator Collaborators Timeline Underway since March 2019 Additional information Microplastics can act as vectors for other environmental contaminants, absorbing organic and inorganic pollutants. Previously, there had been no known studies examining this vector effect or related kinetics. The current project aims to construct a model for estimating the vector effect […] Read more

  • Sources, emissions and environmental risk of microplastics

    Researchers / Institutional Affiliations Principal Investigator Collaborators Timeline Underway since March 2023 Additional information This research project aims to facilitate realistic and effective risk management strategies to mitigate microplastic pollution. The project focuses on analyzing the load and sources of microplastics in Tokyo Bay, and conducting practical risk assessments. Leveraging material flow analysis and precise […] Read more

  • Ecotoxicological risk assessment for microplastics

    Researchers / Institutional Affiliations Principal Investigator Collaborators Timeline Underway since March 2023 Additional Information There is currently a lack of data on risks posed by microplastics in natural ecosystems. The purpose of this project is to assess the ecological risk posed by microplastics using Osaka Bay as a model case. First, researchers investigated microplastic residues […] Read more

  • Assessing microplastic deposition in sediment cores from a contiguous water system (microDETECT)

    Researchers / Institutional Affiliations Principal Investigator Collaborators Timeline The project runs from early 2024 to early 2026 (24 months). Additional information It will assess how the composition and abundance of transported MP have changed over time by determining deposition rates in riverine, estuarine and marine sediment cores collected from multiple sampling sites, as well as […] Read more
