Thesis Overview

Research Overview: The project titled "Assessment of Microplastic Pollution in Freshwater Ecosystems: Impacts and Mitigation Strategies" aims to address the growing concern of microplastic pollution in freshwater environments and its detrimental effects on aquatic ecosystems and human health. Microplastics, small plastic particles less than 5mm in size, have become a pervasive pollutant in aquatic systems worldwide, posing a significant threat to biodiversity and ecosystem functioning. The research will delve into the sources, distribution, and fate of microplastics in freshwater ecosystems, focusing on rivers, lakes, and streams. By conducting comprehensive field surveys and laboratory analyses, the study will assess the abundance and characteristics of microplastics in different freshwater habitats, identifying hotspots of pollution and potential pathways of contamination. Furthermore, the project will investigate the ecological impacts of microplastics on aquatic organisms, including fish, invertebrates, and algae. Through experimental studies and ecological modeling, the research will elucidate how microplastic exposure affects species diversity, population dynamics, and food web interactions in freshwater ecosystems. In addition to ecological impacts, the project will explore the implications of microplastic pollution for human health and well-being. By examining the bioaccumulation of microplastics in freshwater biota and assessing potential risks to human consumers, the study will provide valuable insights into the transfer of microplastics through the food chain and their potential health effects on human populations. Moreover, the research will evaluate existing mitigation strategies and management approaches aimed at reducing microplastic pollution in freshwater environments. By conducting stakeholder interviews, policy analyses, and cost-benefit assessments, the study will identify effective measures for preventing, monitoring, and mitigating microplastic contamination in freshwater ecosystems. Overall, this project seeks to advance our understanding of microplastic pollution in freshwater ecosystems and contribute to the development of science-based solutions for addressing this pressing environmental issue. By integrating field research, laboratory experiments, and stakeholder engagement, the study aims to inform evidence-based policy decisions and promote sustainable management practices to safeguard the health and integrity of freshwater ecosystems for future generations.
