Summary

Researchers sampled surface microplastics (0.5 to 5 mm) at 98 stations across the Pacific Ocean, Sea of Okhotsk, and Sea of Japan during an August 2023 cruise, using FT-IR ATR spectroscopy to identify polymer types among over 4,000 detected particles and map regional pollution distributions.

Study Type Environmental

Data on surface microplastic concentrations (0.5 - 5 mm) in the Pacific Ocean, Sea of Okhotsk and Sea of Japan were obtained. Sampling was carried out during cruise 23/4 of the R/V P̈rofessor Multanovskyïn August 2023 using a neuston net (330 µm). A Perkin Elmer FT-IR ATR Spectrum Two spectrometer was used to identify the polymer composition of microplastic particles. More than 4000 potential microplastic particles were detected at 98 stations. The water area of the southeastern tip of the Kamchatka is insignificantly polluted with microplastics. Surface water samples are almost free of microplastic particles. At 20 Also see: https://micro2024.sciencesconf.org/559731/document
