Nanoplastic pollution found at both of Earth’s poles for first time

Tiny particles including tyre dust found in ice cores stretching back 50 years, showing global plastic contamination

Nanoplastic pollution has been detected in polar regions for the first time, indicating that the tiny particles are now pervasive around the world.

The nanoparticles are smaller and more toxic than microplastics, which have already been found across the globe, but the impact of both on people's health is unknown.
