Thesis Overview

The project "Investigating the impact of microplastics on aquatic ecosystems" aims to explore the consequences of microplastic pollution on the delicate balance of aquatic environments. Microplastics, defined as plastic particles less than 5mm in size, have become a prevalent pollutant in water bodies worldwide due to their widespread use in various consumer products and inefficient waste management practices. This research overview delves into the significance of studying microplastic pollution in aquatic ecosystems, the current state of knowledge in the field, the research objectives, methodology, and the expected outcomes of the study. Aquatic ecosystems, including rivers, lakes, oceans, and estuaries, play a crucial role in supporting biodiversity, providing ecosystem services, and sustaining livelihoods. However, the increasing presence of microplastics in these environments poses a significant threat to their health and functioning. Microplastics can enter aquatic ecosystems through various pathways, such as direct discharge from industrial sources, runoff from urban areas, and the fragmentation of larger plastic debris. Once in the water, these particles can persist for long periods, interact with biota, and accumulate in the food chain, leading to potential ecological and human health risks. Despite growing concern about the impacts of microplastics, there are still knowledge gaps regarding their sources, distribution, behavior, and effects on aquatic organisms and ecosystems. This project seeks to address these gaps by conducting a comprehensive investigation into the presence and dynamics of microplastics in selected aquatic environments. The specific objectives include identifying the sources and types of microplastics, assessing their distribution and abundance, investigating their interactions with aquatic organisms, and evaluating their potential ecological implications. To achieve these objectives, the research will employ a combination of field surveys, laboratory analyses, and modeling approaches. Sampling sites will be selected to represent different types of aquatic ecosystems and varying levels of human influence. Water, sediment, and biota samples will be collected and analyzed for microplastic content using microscopy and spectroscopic techniques. The data obtained will be used to characterize the spatial and temporal patterns of microplastic pollution, assess its impacts on aquatic biota, and inform management strategies to mitigate its effects. Overall, this research overview highlights the importance of investigating the impact of microplastics on aquatic ecosystems to understand the scope of the problem, inform policy and management decisions, and ultimately safeguard the health and integrity of these vital environments. By shedding light on the dynamics of microplastic pollution and its consequences, this project aims to contribute valuable insights to the field of environmental science and support efforts to address the growing challenge of plastic pollution in aquatic ecosystems.
