Thesis Abstract

Abstract
The accumulation of microplastics in marine environments has become a pressing environmental issue with significant implications for marine ecosystems. This thesis investigates the impact of microplastics on marine ecosystems through a case study conducted in a coastal region. The study aims to assess the distribution, abundance, and characteristics of microplastics in the marine environment, as well as their potential effects on marine organisms and ecosystems. Chapter 1 provides an introduction to the research topic, presenting the background of the study, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definition of key terms. The chapter sets the stage for the research by highlighting the importance of understanding the impact of microplastics on marine ecosystems. Chapter 2 presents a comprehensive literature review on microplastics in marine environments. It explores the sources, distribution, transport, and fate of microplastics in the marine ecosystem, as well as their potential ecological and biological impacts. The chapter also reviews existing methodologies for microplastic analysis and monitoring in marine environments. Chapter 3 outlines the research methodology employed in the study. It details the sampling design, collection methods, sample processing, and analytical techniques used to quantify and characterize microplastics in the coastal region. The chapter also discusses the assessment of potential impacts on marine organisms and ecosystems through field observations and laboratory experiments. Chapter 4 delves into the discussion of findings from the case study. It presents the results of microplastic analysis, including spatial distribution patterns, abundance levels, polymer types, and sizes found in the marine environment. The chapter also discusses the potential ecological implications of microplastics on marine organisms, highlighting the risks and challenges posed by their presence in coastal ecosystems. Chapter 5 concludes the thesis by summarizing the key findings and implications of the study. It discusses the significance of the research findings in the context of marine conservation and environmental management. The chapter also highlights future research directions and recommendations for mitigating the impact of microplastics on marine ecosystems. In conclusion, this thesis contributes to the growing body of knowledge on the impact of microplastics on marine ecosystems. By conducting a case study in a coastal region, the research sheds light on the distribution, abundance, and effects of microplastics in the marine environment. The findings of this study have important implications for policy development, conservation efforts, and sustainable management of marine ecosystems in the face of plastic pollution.
