Thesis Abstract

Abstract
The presence of microplastics in marine environments has become a major concern due to their potential adverse effects on marine organisms and ecosystems. This thesis presents a comprehensive assessment of microplastic contamination in coastal ecosystems and its impact on marine organisms. The study aimed to investigate the sources, distribution, and abundance of microplastics in coastal areas, as well as the physiological and ecological implications for marine organisms. Chapter 1 provides an introduction to the research topic, outlining the background of the study, problem statement, objectives, limitations, scope, significance, structure of the thesis, and key definitions of terms. The chapter sets the stage for understanding the importance of addressing microplastic contamination in coastal ecosystems. Chapter 2 presents a detailed literature review on microplastic pollution, focusing on the sources and pathways of microplastics in marine environments, their physical and chemical properties, as well as the impacts on marine organisms and ecosystems. The review synthesizes current knowledge and gaps in research related to microplastic contamination in coastal areas. Chapter 3 describes the research methodology employed in this study, including sampling techniques, sample processing and analysis methods, data collection procedures, and statistical analyses. The chapter outlines the steps taken to investigate microplastic contamination in coastal ecosystems and assess its effects on marine organisms. In Chapter 4, the findings of the study are discussed in detail, highlighting the sources and distribution patterns of microplastics in coastal areas, as well as the interactions between microplastics and marine organisms. The chapter also explores the potential ecological consequences of microplastic contamination on coastal ecosystems. Chapter 5 presents the conclusion and summary of the thesis, summarizing the key findings, implications, and recommendations for future research and management strategies. The chapter discusses the importance of addressing microplastic contamination in coastal ecosystems to protect marine organisms and maintain the health of marine environments. In conclusion, this thesis contributes to the growing body of knowledge on microplastic pollution in coastal ecosystems and its impact on marine organisms. By understanding the sources, distribution, and effects of microplastics, this study provides valuable insights for policymakers, researchers, and stakeholders working towards mitigating the impacts of microplastic contamination on marine ecosystems.
