Thesis Abstract

Abstract
Microplastic pollution has emerged as a significant environmental concern globally, with freshwater ecosystems being particularly vulnerable to its adverse effects. This thesis presents a comprehensive assessment of microplastic pollution in a local river, aiming to investigate the sources, distribution, and potential impacts of microplastics on aquatic organisms and the surrounding environment. The study involves a detailed analysis of water samples, sediment samples, and biological samples collected from various sites along the river. Chapter 1 provides an introduction to the research topic, highlighting the background of the study, the problem statement, objectives, limitations, scope, significance, structure of the thesis, and key definitions of terms. The literature review in Chapter 2 explores existing knowledge on microplastic pollution in freshwater ecosystems, covering topics such as sources of microplastics, distribution patterns, ecological impacts, and current mitigation strategies. Chapter 3 details the research methodology, including sampling techniques, sample processing procedures, and analytical methods used for the identification and quantification of microplastics. The chapter also outlines the statistical analyses employed to interpret the data collected during the study. Chapter 4 presents a comprehensive discussion of the findings, including the abundance and characteristics of microplastics in different environmental compartments, as well as potential ecological risks associated with their presence. The conclusion in Chapter 5 summarizes the key findings of the study, highlighting the main implications for freshwater ecosystem management and conservation efforts. Recommendations for future research and policy interventions to address microplastic pollution in rivers are also provided. Overall, this thesis contributes valuable insights into the assessment of microplastic pollution in freshwater ecosystems, emphasizing the urgent need for proactive measures to mitigate this growing environmental threat.
