Thesis Abstract

Abstract
The presence of microplastics in marine ecosystems has become a global environmental concern due to their ubiquitous distribution and potential adverse impacts on aquatic organisms and human health. This thesis presents a comprehensive assessment of microplastic pollution in coastal environments, focusing on a selected coastal region. The study aims to investigate the sources, distribution, abundance, and characteristics of microplastics in the coastal area, as well as their potential ecological and human health implications. Chapter One provides an introduction to the research topic, outlining the background, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definition of terms. The literature review in Chapter Two critically examines existing studies on microplastic pollution in coastal environments, covering topics such as sources of microplastics, distribution patterns, impacts on marine life, and mitigation strategies. Chapter Three details the research methodology employed in this study, including sampling techniques, sample processing, and analytical methods for microplastic identification and quantification. The chapter also discusses data analysis and quality control measures implemented to ensure the reliability and validity of the research findings. In Chapter Four, the results of the study are presented and discussed in detail. This includes the identification of microplastic types, sizes, shapes, and concentrations found in the selected coastal region. The chapter also explores the spatial and temporal distribution patterns of microplastics and assesses their potential ecological impacts on marine organisms and ecosystems. Finally, Chapter Five provides a summary of the key findings, conclusions drawn from the research, and recommendations for future studies and environmental management strategies. The thesis concludes with an overall assessment of the microplastic pollution situation in the coastal region and highlights the importance of continued monitoring and mitigation efforts to address this growing environmental issue. Overall, this thesis contributes to the existing body of knowledge on microplastic pollution in coastal environments and provides valuable insights into the extent of contamination, potential risks, and possible solutions to mitigate the impacts of microplastics on marine ecosystems and human health.

Thesis Overview

The project titled "Assessment of Microplastic Pollution in Coastal Environments: Case Study of a Selected Coastal Region" aims to investigate the extent and impact of microplastic pollution in a specific coastal region. Microplastics, which are tiny plastic particles less than 5mm in size, have become a significant environmental concern due to their widespread distribution in marine ecosystems and potential negative effects on marine life and human health. The research will begin with a comprehensive literature review to provide a background on microplastic pollution, including sources, distribution, and known impacts. This review will help establish the current state of knowledge on microplastics in coastal environments and identify gaps in research that the study aims to address. The project will then focus on the selected coastal region, conducting field surveys and sampling to assess the levels of microplastic pollution in different coastal habitats such as beaches, estuaries, and marine waters. Various sampling techniques will be employed to collect and analyze microplastic samples, including visual surveys, sediment coring, and water filtration methods. Data analysis will involve quantifying the abundance, distribution, and characteristics of microplastics in the study area, including the types of polymers present and their potential sources. Statistical analyses will be used to determine correlations between microplastic concentrations and environmental variables such as proximity to urban areas, tidal patterns, and shoreline morphology. The research methodology will also include assessing the ecological impacts of microplastic pollution on local marine organisms through field observations and laboratory experiments. This will help elucidate the potential risks posed by microplastics to marine biodiversity and ecosystem functioning in the coastal region. The findings of the study will be discussed in detail in the results and discussion section, highlighting the key patterns and trends observed in microplastic pollution levels and ecological impacts. The implications of the research findings for environmental management and conservation efforts in the coastal region will be addressed, along with recommendations for mitigation strategies to reduce microplastic pollution. In conclusion, the project aims to contribute valuable insights into the understanding of microplastic pollution in coastal environments and its implications for marine ecosystems. By conducting a detailed assessment of microplastic pollution in a selected coastal region, this research seeks to inform policy decisions and management actions aimed at preserving the health and integrity of coastal ecosystems for future generations.
