VIS–NIR–SWIR microplastics spectral library

Summary

Scientists created a detailed reference library that maps how different types of plastic reflect light, making it easier to detect and identify tiny plastic particles (microplastics) in the environment using special scanning technology. This matters because better detection tools help researchers track where microplastics end up—including in our water, food, and eventually our bodies—which is a key step toward understanding and reducing our exposure to them. Note that this study itself doesn't test health effects; it simply builds a tool to help find microplastics more accurately.
