Thesis Abstract

Abstract
The presence of microplastics in aquatic environments has become a growing concern due to its potential impact on aquatic ecosystems and human health. This thesis aims to assess the extent of microplastic pollution in urban water bodies and investigate its implications on aquatic ecosystems. The study employs a multidisciplinary approach that combines environmental monitoring techniques, analytical chemistry, and ecological assessments to provide a comprehensive evaluation of the problem. Chapter One provides an introduction to the research topic, presenting the background of the study, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definitions of key terms. Chapter Two comprises a detailed literature review that explores existing knowledge on microplastic pollution, sources, distribution, and its effects on aquatic organisms and ecosystems. Chapter Three outlines the research methodology, including sampling procedures, laboratory analysis techniques, and data collection methods. It also discusses the selection of study sites, sample processing, and quality control measures. The chapter further addresses the ethical considerations and challenges encountered during the research process. Chapter Four presents a thorough discussion of the findings obtained from the fieldwork and laboratory analysis. It evaluates the concentration and types of microplastics found in the water bodies, sediments, and biota, as well as their potential ecological risks. The chapter also examines the relationships between microplastic pollution and environmental factors, such as land use, hydrology, and human activities. In Chapter Five, the conclusion and summary of the thesis are provided, highlighting the key findings, implications, and recommendations for future research and environmental management practices. The study underscores the importance of addressing microplastic pollution in urban water bodies to safeguard aquatic ecosystems and human well-being. Overall, this thesis contributes to the growing body of knowledge on microplastic pollution and its impacts, emphasizing the need for sustainable solutions and policy interventions to mitigate this environmental threat effectively.

Thesis Overview

The project titled "Assessment of Microplastic Pollution in Urban Water Bodies and its Impact on Aquatic Ecosystems" aims to investigate the presence and effects of microplastic pollution in urban water bodies on aquatic ecosystems. Microplastics, defined as plastic particles less than 5mm in size, have become a significant environmental concern due to their widespread distribution and potential adverse impacts on aquatic organisms and ecosystems. The research will begin with a comprehensive literature review to examine existing studies on microplastic pollution in urban water bodies and its implications for aquatic ecosystems. This review will provide a solid theoretical foundation for the subsequent research activities. The methodology chapter will outline the research design, sampling techniques, and analytical methods that will be employed to assess the levels of microplastic pollution in selected urban water bodies. Through field surveys and laboratory analyses, the project will quantify the abundance and types of microplastics present in the water, sediments, and biota of the study sites. The data collected will be used to evaluate the potential sources of microplastic pollution and assess the ecological risks posed by these contaminants to aquatic organisms. Additionally, the project will investigate the bioaccumulation and biomagnification of microplastics in the food web to understand their long-term effects on aquatic ecosystems. The findings from this research will contribute valuable insights into the extent of microplastic pollution in urban water bodies and its impact on aquatic ecosystems. By identifying the sources and pathways of microplastics, as well as their ecological consequences, the study aims to raise awareness about this environmental issue and inform the development of effective mitigation strategies. Ultimately, the project seeks to enhance our understanding of the interactions between microplastics and aquatic ecosystems, providing valuable information for policymakers, conservationists, and other stakeholders working towards environmental sustainability.
