Thesis Overview

The project titled "Assessment of Microplastic Pollution in Freshwater Ecosystems: Impacts and Mitigation Strategies" aims to investigate the presence and effects of microplastic pollution on freshwater ecosystems. Microplastics, defined as plastic particles less than 5mm in size, have become a growing concern globally due to their widespread distribution and potential environmental impacts. Within freshwater ecosystems such as rivers, lakes, and streams, microplastics can accumulate and persist, posing risks to aquatic organisms and ecosystem health. The research will begin with a comprehensive literature review to explore existing knowledge on microplastic pollution in freshwater environments. This review will cover topics such as sources of microplastics, their transport mechanisms, interactions with biota, and potential ecological consequences. By synthesizing current research findings, the study aims to identify gaps in knowledge and areas requiring further investigation. Following the literature review, the research methodology will be outlined, detailing the sampling design, sample collection methods, and analytical techniques to be employed for microplastic detection and quantification in freshwater ecosystems. Field surveys will be conducted in selected freshwater bodies to assess the abundance and distribution of microplastics, as well as their characteristics and potential sources. The project will also investigate the impacts of microplastic pollution on freshwater biota, focusing on both aquatic organisms and the broader ecosystem dynamics. By studying the interactions between microplastics and freshwater organisms, the research aims to elucidate the potential risks posed by microplastics to aquatic life, biodiversity, and ecosystem functioning. Furthermore, the study will explore potential mitigation strategies to address microplastic pollution in freshwater ecosystems. This may involve assessing the efficacy of different mitigation measures, such as source reduction, waste management practices, and ecosystem restoration efforts. By evaluating the effectiveness of these strategies, the research aims to provide practical recommendations for mitigating microplastic pollution and safeguarding freshwater ecosystem health. Overall, the project "Assessment of Microplastic Pollution in Freshwater Ecosystems: Impacts and Mitigation Strategies" seeks to advance our understanding of the extent and consequences of microplastic pollution in freshwater environments. By investigating the impacts of microplastics on freshwater ecosystems and exploring potential mitigation approaches, the study aims to contribute valuable insights to the field of environmental science and support the development of sustainable management practices for protecting freshwater resources.
