Thesis Abstract

Abstract
Microplastic pollution has become a significant environmental concern globally, particularly in coastal ecosystems, where it poses detrimental impacts on marine life and ecosystems. This thesis aims to assess the extent of microplastic pollution in coastal ecosystems, identify its sources, and propose effective mitigation strategies to address this pressing issue. The research methodology employed a combination of field surveys, laboratory analysis, and data synthesis to achieve the research objectives. Chapter One provides an introduction to the topic, highlighting the background of the study, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definition of terms. Chapter Two presents a comprehensive literature review covering ten key aspects related to microplastic pollution in coastal ecosystems, including its ecological impacts, sources, distribution, and current mitigation efforts. Chapter Three details the research methodology, outlining the sampling techniques, analytical methods, data collection procedures, quality control measures, and statistical analysis employed in the study. The chapter also discusses the ethical considerations and limitations of the research methodology. Chapter Four presents an in-depth discussion of the research findings, including the quantification of microplastic pollution levels in coastal ecosystems, identification of predominant sources, spatial distribution patterns, and the effectiveness of existing mitigation strategies. The chapter critically analyzes the results and discusses their implications for environmental conservation and policy development. Chapter Five offers a conclusive summary of the thesis, highlighting the key findings, implications, and recommendations for future research and policy interventions. The thesis underscores the urgency of addressing microplastic pollution in coastal ecosystems through interdisciplinary efforts, public awareness campaigns, policy reforms, and technological innovations. Overall, this research contributes to the growing body of knowledge on microplastic pollution and provides valuable insights for sustainable coastal management and environmental protection.
