Thesis Abstract

Abstract
The presence of microplastics in marine ecosystems has raised significant concerns globally due to their potential adverse impacts on marine life and human health. This thesis presents a comprehensive assessment of microplastics contamination in coastal waters and their potential impact on marine ecosystems. The study aims to investigate the sources, distribution, abundance, and characteristics of microplastics in coastal waters, as well as their interactions with marine organisms and ecosystems. Through a combination of field surveys, laboratory analyses, and data interpretation, the research provides valuable insights into the extent of microplastics pollution and its implications for marine biodiversity and ecosystem health.

Thesis Overview

The project titled "Assessment of Microplastics Contamination in Coastal Waters and Their Potential Impact on Marine Ecosystems" aims to investigate the presence of microplastics in coastal waters and evaluate their potential impact on marine ecosystems. Microplastics, defined as plastic particles less than 5mm in size, have become a significant environmental concern due to their widespread distribution and persistence in aquatic environments. This research seeks to contribute to the understanding of the extent of microplastic contamination in coastal waters and shed light on the implications for marine organisms and ecosystems. The study will begin with a comprehensive literature review to explore existing research on microplastics in coastal waters, including sources of contamination, distribution patterns, and ecological effects. By synthesizing current knowledge in this field, the research aims to identify gaps in understanding and areas that require further investigation. The methodology for this project will involve field sampling of coastal waters to collect water samples for microplastic analysis. Various sampling sites along the coastline will be selected to capture different environmental conditions and anthropogenic influences. Laboratory analysis will be conducted to quantify the abundance and characteristics of microplastics present in the water samples, utilizing microscopy and spectroscopy techniques. Through the analysis of microplastic data and ecological assessments, the research will evaluate the potential impact of microplastics on marine organisms, such as fish, invertebrates, and seabirds. By examining the interactions between microplastics and marine biota, the study aims to elucidate the mechanisms through which microplastics may pose risks to ecosystem health and biodiversity. The findings of this research are expected to provide valuable insights into the extent of microplastic pollution in coastal waters and its consequences for marine ecosystems. By elucidating the pathways of microplastic contamination and understanding their ecological impacts, the study aims to inform policy-making and conservation efforts aimed at mitigating the detrimental effects of microplastics on marine environments. Overall, the project "Assessment of Microplastics Contamination in Coastal Waters and Their Potential Impact on Marine Ecosystems" seeks to advance our knowledge of the environmental challenges posed by microplastics and contribute to the development of sustainable solutions to protect coastal ecosystems and marine biodiversity.
