Thesis Abstract

Abstract
Microplastics, small plastic particles less than 5mm in size, have become a significant concern in coastal ecosystems worldwide due to their widespread presence and potential environmental impact. This thesis aims to analyze the environmental impact of microplastics in coastal ecosystems, focusing on their sources, distribution, interactions with biota, and potential implications for ecosystem health. The introduction provides a background of the study, highlighting the increasing global production and mismanagement of plastics leading to the proliferation of microplastics in marine environments. The problem statement emphasizes the urgent need to understand the ecological consequences of microplastic pollution on coastal ecosystems. The objectives of the study include investigating the sources and distribution of microplastics, assessing their effects on marine organisms, and evaluating the overall environmental implications. The literature review in Chapter Two examines existing research on microplastics in coastal ecosystems, covering topics such as sources of microplastics, pathways of contamination, ecological impacts, and mitigation strategies. The review highlights gaps in current knowledge and identifies key research areas for further investigation. Chapter Three outlines the research methodology, including sampling procedures, laboratory techniques for microplastic analysis, and data interpretation methods. The chapter also discusses the selection of study sites, sample collection protocols, and analytical tools used to quantify microplastic abundance and characteristics in coastal sediments and biota. Chapter Four presents the findings of the study, detailing the sources and distribution patterns of microplastics in the study area, as well as their interactions with marine organisms. The chapter discusses the implications of microplastic contamination on ecosystem health, biodiversity, and food web dynamics, highlighting the need for sustainable management practices to mitigate further environmental damage. The conclusion and summary in Chapter Five provide a comprehensive overview of the key findings and implications of the study. The research underscores the urgent need for multidisciplinary approaches to address the challenges posed by microplastic pollution in coastal ecosystems and emphasizes the importance of policy interventions, public awareness campaigns, and innovative technologies to reduce plastic waste and protect marine environments. In conclusion, this thesis contributes to the growing body of knowledge on microplastic pollution in coastal ecosystems and provides valuable insights into the environmental impact of these pervasive contaminants. The findings and recommendations presented in this study can inform policy decisions, conservation efforts, and future research initiatives aimed at safeguarding coastal ecosystems from the detrimental effects of microplastic pollution.
