To detect particles this small, the team used high-resolution laser direct infrared spectroscopy along with scanning electron microscopy. These tools can identify not just the presence of plastic, but also its size, shape, and chemical composition. They found common materials like polyethylene, PET, polyamide, and PVC, the same plastics used in food packaging, clothing, and everyday household items.
