Abstract:

Previous studies have indicated the means by which micro-sized plastic particles may affect the soil environment, and this could be linked to the behavior of plastics in the soil system and how these particles are influenced by biological responses. Soil-dwelling organisms play a key role in modifying the soil system by constructing bio-pores, and these structural changes are potentially related to the behavior of plastic particles. In this study, we found that micro-sized plastic particles moved into bio-pores within seconds, and that this influx disrupted the movement of springtails (Lobella sokamensis). The springtails moved to avoid becoming trapped, and this behavior created bio-pores in the soil system. The influx of plastic particles into these cavities subsequently immobilized the springtails within. This phenomenon was observed at low a concentration of plastic particles (8 mg/kg), and it likely occurs in actual soil environments. The findings of this study indicate that the behavior of plastic particles in the soil not only disrupts the movement of springtails but also has wider implications for effective management of soils.
