Summary

This study tested the toxicity of microplastics derived from aged and unaged conventional and biodegradable mulching films on the estuarine bivalve Scrobicularia plana, finding that both types caused harm to this ecologically important species. Aged microplastics showed different toxicity profiles compared to fresh particles.

Human activities, and more specifically agricultural and horticultural activities, generate plastic pollution of soils, particularly by microplastics (MP). This pollution by MP is now ubiquitous and raises the question of its impact on the health of ecosystems in different compartments along the soil/aquatic continuum. The objective of this study is to assess the impact of aging on the toxicity of conventional (Polyethylene, PE) and biodegradable (Polylactic Acid/Polybutylene Adipate Terephthalate, PLA/PBAT) mulching films microplastics on a key organism of the estuarine compartment, an environment at the soil/water interface. The estuarine bivalve Scrobicularia plana was exposed for 21 days to two environmental concentrations (0.008µg/L and 100µg/L) of microplastics ( Also see: https://micro2024.sciencesconf.org/558522/document
