Thesis Overview

The research project titled "Assessment of Microplastic Pollution in Freshwater Ecosystems: Impacts and Mitigation Strategies" aims to investigate the presence and effects of microplastic pollution in freshwater ecosystems, focusing on the impacts it has on the environment and exploring potential mitigation strategies. Microplastics, which are tiny plastic particles less than 5mm in size, have become a significant environmental concern due to their widespread presence in aquatic environments and potential negative consequences on ecosystem health. The study will begin with a comprehensive literature review to establish the current state of knowledge regarding microplastic pollution in freshwater ecosystems. This review will cover topics such as the sources and distribution of microplastics, their interactions with aquatic organisms, and the potential ecological and human health risks associated with their presence in freshwater systems. Following the literature review, the research will proceed to assess the extent of microplastic pollution in selected freshwater ecosystems through field sampling and laboratory analysis. Various sampling techniques will be employed to collect water, sediment, and biota samples from different locations within the freshwater ecosystems under investigation. Subsequent laboratory analysis will involve the identification and quantification of microplastic particles in the collected samples using microscopy and spectroscopic techniques. The study will also investigate the impacts of microplastic pollution on freshwater ecosystems, with a focus on potential effects on aquatic organisms, ecosystem dynamics, and water quality. By examining the interactions between microplastics and freshwater biota, the research aims to elucidate the direct and indirect effects of microplastic pollution on ecosystem health and functioning. Furthermore, the project will explore potential mitigation strategies to address and reduce microplastic pollution in freshwater ecosystems. This will involve evaluating existing management practices, developing innovative solutions, and proposing recommendations for effective mitigation measures to minimize the input of microplastics into freshwater environments. Overall, this research project seeks to provide valuable insights into the assessment of microplastic pollution in freshwater ecosystems, elucidate its impacts on the environment, and propose practical mitigation strategies to address this pressing environmental issue. By contributing to the understanding of microplastic pollution in freshwater systems, the study aims to inform policy decisions, guide conservation efforts, and promote sustainable management practices for the protection of freshwater ecosystems and the biodiversity they support.
