Summary

Researchers assessed how the presence of polystyrene microplastics affects the bioaccumulation of silver nanoparticles in the filter-feeding zooplankton Daphnia magna. The study provides laboratory data on silver uptake kinetics at environmentally relevant concentrations, contributing to understanding how microplastics may interact with other contaminants to alter their biological availability to aquatic organisms.

Models

Microplastics (MPs) are an environmental concern. They can interact with other contaminants and pose new threats to organisms. We assessed the effect MPs on silver (Ag) bioaccumulation in the filter-feeding zooplankton Daphnia magna exposed to Ag nanoparticles at environmentally relevant concentrations.
