14 C-labelled nanoplastics reveal size-dependent bioaccumulation in juvenile rainbow trout ( Oncorhynchus mykiss )

Key Points

• This research aims to examine how the size of nanoplastics affects their accumulation in juvenile rainbow trout.
• Experiment involving juvenile rainbow trout
• Utilization of C-14 labelled nanoplastics
• Analysis of residence time and translocation of nanoplastics
• Larger nanoplastics showed longer residence time in the trout
• Translocation of smaller nanoplastics was more significant than larger ones
• Indicates that size influences bioaccumulation rates
