Summary

This study used a full-Stokes polarization camera to visualize microplastics consumed by aquatic organisms by exploiting the birefringent optical properties of plastic particles. The method enables real-time detection and quantification of microplastics inside organisms without destructive sample preparation.

Study Type In vivo

Waterborne microplastics can be difficult to detect in situ. We report on a method of visualizing microplastics using their inherent birefringence. By using a full-Stokes polarization camera for measurement, the microplastics can be visualized and quantified in real-time. In addition, we show that the camera is able to visualize PET microplastics consumed by brine shrimps in vivo.
