Summary

Urban environments generate microplastics through road runoff, stormwater drainage, and inadequate waste management, releasing particles directly into local waterways at high concentrations. Cities are both major sources and exposure zones for microplastics, making urban infrastructure improvements a priority for reducing human contact with contaminated water and air.

We all use plastics for a variety of purposes, and the amount of plastic produced and used is increasing worldwide, now reaching over 380 million metric tons (MMT) annually. Waste management in highly populated areas is currently insufficient to prevent large amounts...
