Assessment of microplastic pollution in coastal sediments and its impact on marine biodiversity

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.
