ClearQuantitative Tracking of Nanoplastic Uptake and Distribution in Zebrafish by Single-Particle Inductively Coupled Plasma Mass Spectrometry
Researchers developed a new method to track nanoplastics at the single-particle level in zebrafish using europium-doped polystyrene particles and mass spectrometry. They found that while most nanoplastics accumulated in the intestine, particles continuously penetrated into internal organs including the brain, demonstrating the ability to cross the blood-brain barrier. The study suggests that nanoplastics pose a systemic exposure risk, though the chorion of fish eggs appears to block their entry.

Researchers used advanced mass spectrometry to track how polystyrene nanoplastics accumulate in and are cleared from zebrafish tissues over time. The nanoplastics concentrated most in the intestine, liver, and gills, with only partial clearance after the exposure ended. This study provides important data on how persistent nanoplastics can be in living organisms, which helps scientists better assess the long-term risks of plastic particle exposure.
