Nanoplastics Invade Fish Organs, Raising Human Health Alarms

City University of Hong Kong scientists discover nanoplastics enter zebrafish organs through water and food, spreading to brain and reproductive systems within 24 hours, with implications for human health.

This research reveals how microscopic plastic pollution enters living organisms and spreads throughout their bodies, potentially affecting nervous and reproductive systems. Since zebrafish share physiological similarities with humans, these findings suggest nanoplastics could similarly infiltrate human bodies through environmental exposure, drinking water, and food chains. The study's computer model provides crucial tools for predicting plastic contamination impacts across species, highlighting an urgent public health concern as plastic pollution breaks down into increasingly smaller, more invasive particles that could accumulate in our organs over time.
