Long-Term Environmental Change Monitoring in the Sagami River Estuary, Part 12 (Assessment of the Current State of Microplastics in Estuarine Ecosystems)
Original title: 相模川河口域における長期環境変動のモニタリング12 （河口域生態系マイクロプラスチックの実態把握）
Summary
This Japanese study monitored microplastics as part of long-term environmental change monitoring in the Sagami Bay Estuary, using a plankton net (mesh 0.2 mm) to collect ocean surface samples. FT-IR (ATR) and Raman spectroscopy were used for polymer identification, with polyethylene and polypropylene identified as the most prevalent plastic types in the estuary samples.
As part of long-term monitoring of environmental changes in the Sagami Bay Estuary, a survey of microplastics was conducted in the estuary. Measurement samples were taken from the ocean surface using a plankton net (mesh size : 0.2 mm). Most of the plastics collected were polyethylene and polypropylene. FT-IR (ATR) and Raman spectroscopy were effective in identifying the polymer species in samples
