Thesis Abstract

Abstract
Microplastic pollution is a pressing environmental issue that has gained increasing attention in recent years due to its potential impact on freshwater ecosystems. This thesis presents a comprehensive assessment of microplastic pollution in freshwater ecosystems, focusing on the sources, distribution, and ecological implications of microplastics. The study employed a combination of field surveys, laboratory analysis, and ecological assessments to investigate the presence and abundance of microplastics in different freshwater environments. Chapter 1 provides an introduction to the research topic, including the background of the study, problem statement, objectives, limitations, scope, significance of the study, structure of the thesis, and definitions of key terms. Chapter 2 presents a detailed literature review covering ten key aspects related to microplastic pollution in freshwater ecosystems, including sources, transport mechanisms, impacts on aquatic biota, and current monitoring techniques. Chapter 3 outlines the research methodology, detailing the sampling protocols, laboratory analysis techniques, and data interpretation methods used to assess microplastic pollution in freshwater ecosystems. This chapter also discusses the selection of study sites, sample collection procedures, and quality control measures implemented to ensure the reliability and accuracy of the data collected. Chapter 4 presents a comprehensive discussion of the findings obtained from the field surveys, laboratory analysis, and ecological assessments. The chapter examines the spatial and temporal distribution of microplastics in different freshwater environments, identifies the predominant types of microplastics present, and evaluates their potential ecological impacts on aquatic organisms and ecosystems. Finally, Chapter 5 provides a conclusion and summary of the thesis, highlighting the key findings, implications, and recommendations for future research and management strategies to mitigate microplastic pollution in freshwater ecosystems. The thesis contributes to the growing body of knowledge on microplastic pollution in freshwater environments and underscores the importance of addressing this issue to protect the health and integrity of freshwater ecosystems. Keywords Microplastic pollution, Freshwater ecosystems, Field surveys, Laboratory analysis, Ecological assessment, Environmental impact.
