[O11-P106] Spatial and Temporal Distribution of MP in Beach Sand: Teaching Materials to Encourage Personal Engagement with MP Issue

*Momoka Noda1 (1.Tokyo Gakugei University Senior High School)

Keywords:Microplastics, Spatial distribution, Temporal distribution, Teaching material, Nile Red

In recent years, marine pollution caused by microplastics (MPs) has become a global issue. This study aimed to clarify the spatial and temporal distribution of microplastics on a familiar local beach and to encourage more people to view marine pollution as a personal concern. Sand samples were collected and analyzed using Nile Red staining to quantify the amount of microplastics in the sand.
The results showed that, in terms of spatial distribution, microplastics tended to accumulate most in the middle zone between the land and the sea. In terms of temporal distribution, a greater concentration was found on the surface layer of the sand. Future challenges include collecting more data and analyzing environmental conditions to further understand these distributions.
