Summary

A survey conducted in 2019 confirmed that the pollution situation in the middle stream of the Tamagawa River, which conducted thesurvey as a result, was very serious. Microplastics were detected from more than 95% of oikawa captured as a specimen.

And all of the detected microplastics are primary microplastics, 95% of those of fibrous mobile, 5% were microbeads. As revealed from the microplastic images detected, many are presumed to be primary microplastics discharged from the water reprocessing center.
