Abstract

In recent years, the marine plastic problem has attracted attention. However, the following three problems have been pointed out regarding marine plastics. 1. Overestimation or underestimation of the amount of plastic waste released into the ocean due to inaccurate measurements. 2. It is not possible to accurately measure plastic pieces that have been refined by ultraviolet rays or mechanical waves. 3. Transition of marine plastic to sediments. In this study, we investigated a method for accurately quantifying microplastics and applied the established analytical method to the analysis of microplastics in Osaka Bay and its inflowing rivers.
