Thesis Abstract

Abstract
This thesis focuses on the assessment of microplastics contamination in freshwater ecosystems. Microplastics, defined as plastic particles less than 5mm in size, have emerged as a significant environmental concern due to their widespread distribution and potential adverse impacts on aquatic organisms and ecosystems. The presence of microplastics in freshwater environments poses a threat to water quality, biodiversity, and human health. Despite growing awareness of this issue, there is still a lack of comprehensive studies on the extent of microplastics contamination in freshwater ecosystems. Chapter 1 provides an introduction to the research topic, including the background of the study, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definitions of key terms. The chapter sets the stage for understanding the importance of assessing microplastics contamination in freshwater environments. Chapter 2 presents a detailed literature review covering ten key aspects related to microplastics contamination in freshwater ecosystems. This section synthesizes existing research findings, methodologies, and gaps in knowledge to provide a comprehensive overview of the current state of knowledge on the topic. Chapter 3 outlines the research methodology employed in this study, including sample collection, analysis techniques, data interpretation, and quality control measures. The chapter discusses the rationale behind the chosen methodology and justifies its suitability for assessing microplastics contamination in freshwater ecosystems. Chapter 4 presents the findings of the study, including the identification and quantification of microplastics in water samples from selected freshwater ecosystems. The chapter discusses the spatial distribution, size distribution, polymer composition, and potential sources of microplastics contamination in the study areas. Chapter 5 offers a conclusion and summary of the thesis, highlighting the key findings, implications for environmental management, and recommendations for future research. The chapter emphasizes the importance of addressing microplastics contamination in freshwater ecosystems to protect water quality, aquatic ecosystems, and human health. Overall, this thesis contributes to the growing body of knowledge on microplastics contamination in freshwater ecosystems and provides valuable insights for policymakers, researchers, and stakeholders working towards mitigating the impact of microplastics on aquatic environments.
