Microplastic Pollution in Urban Waterways: Sources and Solutions

Abstract

Microplastics have emerged as a pervasive pollutant in urban aquatic ecosystems. This research investigates the primary sources of microplastic contamination in metropolitan rivers, focusing on runoff, wastewater treatment plants, and consumer products. Sampling from five major cities reveals alarming concentrations of microplastics, with implications for biodiversity and human health. The paper proposes policy interventions and technological innovations, including filtration systems and biodegradable alternatives, to mitigate the crisis.
