Thesis Abstract

Abstract
The presence of microplastics in the marine environment has become a major concern due to its potential impact on marine biodiversity. This thesis aims to assess the extent of microplastic pollution in coastal sediments and its implications for marine ecosystems. The study focuses on identifying sources of microplastic pollution, quantifying the abundance and distribution of microplastics in coastal sediments, and evaluating the potential effects on marine biodiversity. Chapter One 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. The chapter sets the foundation for understanding the importance of addressing microplastic pollution in coastal environments. Chapter Two presents a comprehensive literature review on microplastic pollution, marine biodiversity, and the impact of microplastics on marine ecosystems. The review synthesizes existing knowledge on the sources, distribution, and ecological effects of microplastics in coastal sediments, providing a theoretical framework for the research study. Chapter Three outlines the research methodology, including the sampling procedures, laboratory analysis techniques, data collection methods, and statistical analysis. The chapter describes how sediment samples were collected from various coastal sites, processed for microplastic analysis, and quantified to assess the extent of pollution. Chapter Four presents the findings of the study, highlighting the abundance and distribution of microplastics in coastal sediments and their potential impact on marine biodiversity. The chapter discusses the types of microplastics found, their spatial distribution, and the implications for marine organisms and ecosystems. Chapter Five provides a summary of the research findings and conclusions drawn from the study. The chapter discusses the implications of the results for environmental management and conservation efforts, emphasizing the need for mitigation measures to reduce microplastic pollution in coastal environments. Overall, this thesis contributes to the growing body of knowledge on microplastic pollution in coastal sediments and its impact on marine biodiversity. The findings underscore the importance of addressing this environmental issue to protect marine ecosystems and promote sustainable management practices.

Thesis Overview

The research project titled "Assessment of microplastic pollution in coastal sediments and its impact on marine biodiversity" aims to investigate the presence and effects of microplastic pollution in coastal sediments on marine biodiversity. Microplastics, defined as plastic particles less than 5mm in size, have become a major environmental concern due to their widespread distribution and potential harm to marine ecosystems. Coastal sediments serve as a sink for microplastics, accumulating over time and posing risks to marine organisms. The study will begin with a comprehensive review of existing literature on microplastic pollution, coastal sediments, and marine biodiversity to establish a solid foundation for the research. This literature review will cover topics such as sources of microplastics, transport mechanisms, accumulation in sediments, and the impacts on marine organisms and ecosystems. The research methodology will involve field sampling of coastal sediments from selected sites to quantify the abundance and distribution of microplastics. Various analytical techniques, such as microscopy and spectroscopy, will be employed to identify and characterize the types of microplastics present in the sediments. In addition, biological assays may be conducted to assess the potential toxic effects of microplastics on marine organisms. The findings of the study will be presented and discussed in detail in the results and discussion chapter. The research will aim to evaluate the levels of microplastic pollution in coastal sediments, assess the potential risks to marine biodiversity, and identify hotspots of contamination. The implications of these findings for marine conservation and management will also be explored. In conclusion, the research project "Assessment of microplastic pollution in coastal sediments and its impact on marine biodiversity" seeks to contribute valuable insights into the growing issue of microplastic pollution in coastal environments. By shedding light on the extent of contamination and its effects on marine biodiversity, the study aims to inform effective mitigation strategies and conservation efforts to protect coastal ecosystems for future generations.
