Assessment of Microplastic Pollution in Coastal Waters and its Impact on Marine Ecosystems

Thesis Abstract

Abstract
The presence of microplastics in coastal waters has emerged as a significant environmental concern globally, posing a threat to marine ecosystems and biodiversity. This thesis addresses the assessment of microplastic pollution in coastal waters and its impact on marine ecosystems. The study aims to investigate the sources, distribution, abundance, and characteristics of microplastics in selected coastal areas, as well as to evaluate their potential effects on marine organisms and ecosystems. The research methodology involves a combination of field surveys, laboratory analyses, and data interpretation to quantify and characterize microplastic particles in water samples, sediments, and biota. Additionally, the study will assess the bioaccumulation and biomagnification of microplastics in marine organisms to understand the potential risks to ecosystem health. Chapter 1 provides an introduction to the research topic, background information, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definition of key terms. Chapter 2 presents a comprehensive literature review on microplastic pollution, including sources, distribution, effects on marine life, and current mitigation strategies. Chapter 3 outlines the research methodology, including sampling techniques, laboratory analyses, data processing, and statistical methods. It also discusses the ethical considerations and challenges encountered during the research process. Chapter 4 presents the detailed findings of the study, including the quantification and characterization of microplastics in coastal waters, sediments, and biota. The chapter also examines the potential impact of microplastics on marine organisms and ecosystems, highlighting the implications for biodiversity and ecosystem functioning. Chapter 5 concludes the thesis by summarizing the key findings, discussing their implications for marine conservation and management, and suggesting future research directions. The study contributes to the growing body of knowledge on microplastic pollution in coastal waters and provides valuable insights into the potential risks posed by these persistent pollutants to marine ecosystems.
