Thesis Abstract

Abstract
The proliferation of plastic pollution in marine environments has become a pressing global issue, with microplastics emerging as a significant concern due to their widespread distribution and potential ecological impacts. This thesis presents a comprehensive assessment of microplastic pollution in coastal marine environments, focusing on the sources, distribution, and effects of microplastics on marine ecosystems. The study aims to provide valuable insights into the magnitude of microplastic contamination in coastal waters, identify key sources of microplastics, and assess the potential risks posed by these pollutants to marine organisms and ecosystems. Chapter One of the thesis provides an introduction to the research topic, including the background of the study, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definition of key terms related to microplastic pollution. Chapter Two presents a detailed literature review covering ten key aspects related to microplastic pollution in coastal marine environments. This review examines the current state of knowledge on microplastic sources, distribution patterns, transport mechanisms, ecological impacts, and mitigation strategies. Chapter Three outlines the research methodology employed in this study, detailing the sampling techniques, sample collection procedures, laboratory analysis methods, and data interpretation approaches. The chapter also discusses the selection of study sites, sampling locations, and sampling periods to ensure a representative assessment of microplastic contamination in coastal waters. In Chapter Four, the findings of the study are presented and discussed in detail, focusing on the quantification of microplastic concentrations, identification of predominant polymer types, assessment of spatial distribution patterns, and evaluation of potential ecological risks associated with microplastic pollution. The chapter also examines the relationship between microplastic abundance and environmental variables, such as water quality parameters, sediment characteristics, and biological factors. Finally, Chapter Five provides a comprehensive summary of the research findings, conclusions drawn from the study, and recommendations for future research and policy interventions to address microplastic pollution in coastal marine environments. The thesis underscores the urgent need for concerted efforts at the local, national, and international levels to mitigate the impacts of microplastic pollution and safeguard the health and integrity of marine ecosystems. In conclusion, this thesis contributes to the growing body of knowledge on microplastic pollution in coastal marine environments and highlights the importance of continued research and proactive management strategies to tackle this pervasive environmental threat. By raising awareness, promoting sustainable practices, and fostering collaboration among stakeholders, we can work towards a cleaner, healthier future for our oceans and marine wildlife.

Thesis Overview

The project titled "Assessment of Microplastic Pollution in Coastal Marine Environments" aims to investigate the extent and impact of microplastic pollution in coastal marine environments. Microplastics are tiny plastic particles measuring less than 5 mm in size that pose a significant threat to marine ecosystems and organisms. These microplastics can originate from a variety of sources, including the breakdown of larger plastic debris, microbeads in personal care products, and fibers from synthetic textiles. The research will begin with a thorough review of existing literature on microplastic pollution in coastal marine environments. This review will provide a comprehensive understanding of the current state of knowledge regarding sources, distribution, and potential ecological and human health impacts of microplastics. The study will then proceed to assess the presence and distribution of microplastics in selected coastal marine areas through field sampling and laboratory analysis. Various sampling techniques will be employed to collect water, sediment, and biota samples for microplastic analysis. Advanced analytical methods, such as microscopy and spectroscopy, will be used to identify and quantify microplastics in the samples. Furthermore, the research will investigate the potential effects of microplastic pollution on marine organisms, particularly on filter feeders and other species vulnerable to ingesting microplastics. Biological and ecological indicators will be used to assess the impact of microplastics on marine biodiversity and ecosystem functioning. The findings of this study will contribute valuable insights into the distribution, abundance, and ecological implications of microplastic pollution in coastal marine environments. The results will help raise awareness about the urgent need for effective management strategies to mitigate microplastic pollution and protect marine ecosystems. Ultimately, this research aims to inform policymakers, stakeholders, and the general public about the importance of addressing microplastic pollution to safeguard the health and integrity of coastal marine environments.
