Summary

Researchers compared the ecotoxicological effects of conventional low-density polyethylene microplastics and biodegradable polybutylene adipate terephthalate microplastics on the earthworm Eisenia andrei using an eight-week reproduction test across seven concentration levels. Both polymer types affected earthworm survival, reproduction, and oxidative stress markers, raising questions about whether biodegradable alternatives pose similar soil ecosystem risks.

Microplastic (MP) contamination of soils has become a critical environmental concern. Conventional plastics are mainly used in agricultural practices, but the use of biodegradable materials has increased. However, the effects of these polymers on the environment are poorly understood. The objective of this study was to assess and compare the ecotoxicological effects of mulching film-based microplastics, conventional low-density polyethylene microplastics (PE-MPs), and biodegradable polybutylene adipate terephthalate microplastics (PBAT-BD-MPs) on the earthworm Eisenia andrei. The measured parameters were survival, reproduction, growth, and oxidative stress. The experimental setup included a standard eight-week earthworm reproduction test with seven different microplastic concentrations (0 Also see: https://micro2024.sciencesconf.org/559482/document
