Summary

Researchers developed a new methodology using 50 keV electron beam irradiation to detect trace amounts of polyethylene microplastics in ocean water samples. The technique analyzes photon flux spectra to reveal the presence of plastic contamination at low concentrations.

This study presents a new methodology to reveal traces of polyethylene (the most common microplastic particles, known as a structure of C2H4) in a sample of ocean water by the irradiation of a 50 keV, 1 µA electron beam. This is performed by analyzing the photon (produced by the electrons in water) fluxes and spectra (i.e., fluxes as a function of photon energy) with different types of contaminated water using an adequate device and in particular looking at the peculiar interactions of electrons/photons with the potential abnormal atomic hydrogen (H), oxygen (O), carbon (C), and phosphorus (P) compositions present in the water, as a function of living and nonliving organic organisms with PO4 group RNA/DNA strands in a cluster configuration through a volumetric cells grid.
