Key Points

This research aims to explore how the size of microplastics and nanoplastics affects their toxicity in the Drosophila melanogaster model.
Utilized the Drosophila melanogaster model to assess toxicity levels of varying size MNPs.
Analyzed bioavailability and biodistribution related to particle size.
Examined multi-system damage induced by microplastics and nanoplastics.
Smaller microplastics showed significantly greater toxicity compared to larger counterparts, indicating a size-dependent effect.
Biopermeability was notably increased with reduced particle size, enhancing toxic hazards.
Indications of multi-system damage correlate directly with nanoparticle size reduction.

Implication

Evaluates the effects of microplastics and nanoplastics on toxicity in Drosophila, indicating significant size-related differences.

Abstract

Microplastics and nanoplastics (MNPs) are ubiquitous environmental pollutants that enter organisms and induce multi-system damage. Particle size is a critical determinant of MNPs' bioavailability, biodistribution, and toxic intensity, with smaller particles exhibiting stronger biopermeability and toxic hazards.
