초록
Every year, approximately 350 million tons of plastic waste are generated worldwide. This waste, can degrade into microplastics, owing to factors such as temperature changes and UV exposure. These smaller plastic particles are increasinglyentering the food chain through marine life, thereby raising concerns about their impact on human health. Consequently,there is an increasing need to measure microplastics. Common methods involve direct collection by using a manta trawlequipped with a 330 µm mesh net or performing spectroscopic and thermal analyses on collected samples. However, thesemethods require complex pre-processing, which risk sample destruction. In this study, we developed a system to directlysample microplastics in aquatic environments by using laser-induced fluorescence spectroscopy. Through an analysis of thefluorescence spectra as well as, the with gradient and integration at specific points, we successfully distinguished microplastics of 100, 200, 300, and 500 µm in size, and we also differentiated between polyethylene (PE) and polystyrene (PS)types.
