Thesis Abstract

Abstract
Microplastic pollution has become a significant environmental concern globally, with freshwater ecosystems being particularly vulnerable due to their crucial role in providing essential services to both humans and wildlife. This study aims to assess the extent of microplastic pollution in a local river, investigating the sources, distribution, and potential impacts on aquatic life and ecosystem health. Through a comprehensive analysis of water and sediment samples collected along the river, the study seeks to provide insights into the current status of microplastic contamination in the freshwater environment.
