Seasonal Distribution of Microplastics in Groundwater of Eastern Jeju, Korea

Some studies suggest that microplastics from the soil surface might end up percolating into groundwater. To evaluate this phenomenon in Republic of Korea, Jeju Island(here after Jeju) has been selected as an experimental site. The geological characteristics are volcanic area, consist of mainly basalt which has porous characteristics and high permeability in aquifer. The research area is the eastern part of Jeju with Jocheon and Gujwa town. Sampling site was selected as a lowland within 200 meters above sea level and agriculture in this site use green houses, mulching and plastic coating seeds(pelleting). This study report on that result as the abundance and distribution of microplastics in groundwater per seasonal variation for the eastern Jeju. This research was supported by Korea Environment Industry and Technology Institute (KEITI) through the Measurement, and Risk Assessment Program for Management Project funded by Korea Ministry of Environment (MOE) (202003110010).
