Abstract

An overview of the problem of contamination of water bodies with microplastics and methods of detection and identification of microplastics using optical technologies was carried out on the basis of general information in available Internet sources. Advantages and disadvantages of existing optical methods are determined. Features of the fluorescence spectrum of PE and PET micropastic samples when excited at a wavelength of 365 nm were determined experimentally. During the analysis of the spectra, radiation bands were found, which allow spectral identification of different types of microplastics. A comprehensive hardware solution for visualization of microplastics using a fluorescent probe-analyzer for remote monitoring of microplastics on the water surface and shoreline is proposed.
