Thesis Abstract

Abstract
Microplastic pollution has become a significant environmental concern worldwide, with detrimental impacts on freshwater ecosystems. This thesis focuses on the assessment of microplastic pollution in freshwater ecosystems, aiming to understand its impacts and propose effective mitigation strategies. The study investigates the sources, distribution, and abundance of microplastics in freshwater environments, as well as their potential effects on aquatic organisms and ecosystem health. The research methodology involves a comprehensive literature review to examine existing knowledge on microplastic pollution in freshwater systems. Field surveys and laboratory analyses are conducted to quantify and characterize microplastics in water, sediment, and biota samples collected from various freshwater ecosystems. The study also explores the potential transport mechanisms of microplastics within these environments. The findings reveal a widespread presence of microplastics in freshwater ecosystems, with diverse shapes, sizes, and polymer compositions identified. The impacts of microplastic pollution on aquatic organisms, including ingestion, bioaccumulation, and associated health risks, are discussed. Furthermore, the study evaluates the ecological implications of microplastics on freshwater food webs and ecosystem dynamics. Based on the results, mitigation strategies are proposed to reduce and manage microplastic pollution in freshwater environments. These strategies include enhanced waste management practices, regulatory measures, public awareness campaigns, and innovative technologies for microplastic removal. The effectiveness and feasibility of these mitigation approaches are critically assessed to provide practical recommendations for policymakers, stakeholders, and the general public. In conclusion, this thesis contributes to the current understanding of microplastic pollution in freshwater ecosystems and highlights the urgent need for concerted efforts to address this environmental issue. By implementing proactive measures and promoting sustainable practices, we can safeguard the health and integrity of freshwater ecosystems for future generations.

Thesis Overview

The project titled "Assessment of Microplastic Pollution in Freshwater Ecosystems: Impacts and Mitigation Strategies" aims to investigate the presence, effects, and potential solutions to microplastic pollution in freshwater environments. Microplastics, defined as plastic particles less than 5mm in size, have become a significant environmental concern due to their widespread distribution and harmful impacts on aquatic ecosystems, wildlife, and human health. This research will focus specifically on freshwater ecosystems, which play a crucial role in maintaining biodiversity, supporting aquatic life, and providing essential ecosystem services. The research will begin with a comprehensive literature review to explore the current understanding of microplastic pollution in freshwater environments. This review will cover topics such as sources of microplastics, transport mechanisms, ecological effects, and existing mitigation strategies. By synthesizing existing knowledge, the study aims to identify gaps in the literature and establish a solid foundation for the subsequent research. The primary objectives of the research include assessing the extent of microplastic pollution in selected freshwater ecosystems, investigating the ecological impacts of microplastics on aquatic organisms and ecosystem health, and evaluating the effectiveness of various mitigation strategies in reducing microplastic contamination. Field surveys, laboratory analyses, and ecological assessments will be conducted to achieve these objectives and generate valuable data on the distribution, abundance, and effects of microplastics in freshwater environments. Furthermore, the research will explore innovative mitigation approaches such as the development of bio-based materials, enhanced waste management practices, and policy recommendations to prevent and control microplastic pollution in freshwater ecosystems. By integrating scientific research with practical solutions, the study aims to contribute to the development of effective strategies for mitigating microplastic pollution and safeguarding the health and integrity of freshwater ecosystems. Overall, the project "Assessment of Microplastic Pollution in Freshwater Ecosystems: Impacts and Mitigation Strategies" seeks to advance our understanding of the complexities surrounding microplastic pollution in freshwater environments and provide valuable insights for policymakers, environmental managers, and stakeholders to address this pressing environmental issue effectively. Through a multidisciplinary approach combining fieldwork, laboratory analyses, and policy recommendations, the research aims to catalyze positive changes in the management and conservation of freshwater ecosystems in the face of growing microplastic contamination.
