Thesis Abstract

Abstract
Microplastics, defined as plastic particles less than 5mm in size, have become a major environmental concern due to their widespread presence in marine ecosystems. This thesis investigates the impact of microplastics on marine ecosystems, focusing on their sources, distribution, and potential effects on marine organisms and habitats. The study aims to provide a comprehensive understanding of the issue and contribute to the ongoing efforts to mitigate the adverse effects of microplastics on marine environments.

Thesis Overview

The project titled "Investigating the Impact of Microplastics on Marine Ecosystems" aims to delve into a critical environmental concern that has gained increasing attention in recent years. Microplastics, which are tiny plastic particles less than 5mm in size, have become a pervasive pollutant in marine environments worldwide. These particles originate from various sources such as the breakdown of larger plastic items, microbeads in personal care products, and synthetic fibers from textiles. The research will focus on understanding the extent and implications of microplastic pollution on marine ecosystems, including its effects on marine organisms, food webs, and overall ecosystem health. By investigating the distribution, composition, and concentration of microplastics in different marine habitats, the study aims to provide insights into the sources and pathways of these contaminants in the marine environment. Furthermore, the project will explore the potential ecological and environmental impacts of microplastics on marine organisms, ranging from small zooplankton to apex predators. By conducting field surveys, laboratory experiments, and data analysis, the research aims to elucidate the mechanisms through which microplastics interact with marine biota and assess the potential risks posed by these pollutants to ecosystem functioning and biodiversity. Moreover, the study will investigate the transfer of microplastics through marine food webs and the bioaccumulation of these particles in different trophic levels. By examining the ingestion, absorption, and translocation of microplastics in marine organisms, the research seeks to understand the implications of these contaminants for ecosystem dynamics and human health through seafood consumption. In conclusion, this research project on the impact of microplastics on marine ecosystems represents a critical endeavor to address a pressing environmental issue with far-reaching consequences. By shedding light on the sources, pathways, and ecological effects of microplastic pollution in the marine environment, the study aims to contribute valuable insights for conservation efforts, policy-making, and public awareness regarding the protection and sustainable management of our oceans.
