Summary

Scientists tested dust from French homes and found tiny plastic particles (microplastics) in every sample, showing this contamination is a normal part of everyday indoor environments. Since house dust is something we regularly breathe in and it can settle on food and surfaces, this study is an important first step in understanding how much plastic we might be unknowingly exposed to at home. Researchers still need to figure out what health effects, if any, this exposure causes.
