Assessment of Microplastics Contamination in Coastal Waters and Their Potential Impact on Marine Ecosystems

Thesis Abstract

Abstract
The presence of microplastics in marine ecosystems has raised significant concerns globally due to their potential adverse impacts on marine life and human health. This thesis presents a comprehensive assessment of microplastics contamination in coastal waters and their potential impact on marine ecosystems. The study aims to investigate the sources, distribution, abundance, and characteristics of microplastics in coastal waters, as well as their interactions with marine organisms and ecosystems. Through a combination of field surveys, laboratory analyses, and data interpretation, the research provides valuable insights into the extent of microplastics pollution and its implications for marine biodiversity and ecosystem health.
