Supporting evidence — 6 representative gaps

• Unveiling Microplastic Pollution in the Northern Amazon: First Evidence from the Cauamé River (2026) · Water Air & Soil Pollution · doi

  There is a lack of data on microplastic pollution in the Northern Amazon. There is a need to investigate the spatial and seasonal variability of microplastic pollution. There is a need to identify the dominant polymer types present in freshwater systems.

• Summer Hydrodynamics as a Dual Driver of Microplastic Retention and Settling in Shallow Water Columns (2026) · Water Air & Soil Pollution · doi

  The study is limited to a small-scale mesocosm experiment. The use of a single type of microplastic microsphere may not be representative of all microplastic types. The study does not account for other factors that may affect microplastic transport, such as biological processes.

• Ingestion of synthetic microparticles—microplastics and cellulose-based microfibers, by macroinvertebrates in the highly polluted Tietê River (São Paulo, Brazil) (2026) · Environmental Monitoring and Assessment · doi

  Further research is needed to understand the factors influencing ingestion patterns. Studies should investigate the effects of synthetic microparticles on freshwater invertebrates and their role in aquatic food webs. Research should focus on developing strategies to reduce plastic pollution in aquatic ecosystems.

• Summer Hydrodynamics as a Dual Driver of Microplastic Retention and Settling in Shallow Water Columns (2026) · Water Air & Soil Pollution · doi

  Further studies are needed to investigate the effects of microplastic pollution on aquatic ecosystems. The development of strategies to mitigate microplastic pollution in shallow lakes and reservoirs is necessary. The use of a combination of experiments and simulations to investigate microplastic transport should be further explored.

• Summer Hydrodynamics as a Dual Driver of Microplastic Retention and Settling in Shallow Water Columns (2026) · Water Air & Soil Pollution · doi

  The effect of summer hydrodynamics on microplastic transport is not well understood. There is a need to investigate the role of wind-driven turbulence and thermally induced convection in controlling microplastic retention and settling.
