Microplastics Pollution in the Aquatic Environments

This chapter presents a thorough examination of microplastic pollution in aquatic environments. It begins by introducing microplastics, emphasizing their sources, characteristics, and persistent nature, along with their potential impact on aquatic organisms and ecosystems. The ecological repercussions of microplastic pollution are explored in depth, covering its effects on various organisms such as fish, plankton, and benthic organisms, and the resulting implications for aquatic ecosystem functioning. Additionally, the chapter discusses the potential transfer of microplastics through the food chain and their associated risks to human health. It further delves into an array of remediation technologies devised to combat microplastic pollution, including physical, chemical, and biological methods such as filtration, adsorption, and biodegradation, among others. The advantages and limitations of these technologies are analyzed, supplemented by examples showcasing their successful application across different aquatic environments. Finally, the chapter concludes with a discussion on the challenges and opportunities inherent in addressing microplastic pollution in aquatic ecosystems. These encompass the imperative for further research on microplastic sources and fate, the advancement of more efficient remediation techniques, and the necessity for heightened public awareness and engagement. In sum, this chapter offers a comprehensive and current overview of microplastic pollution in aquatic environments, underscoring the urgency of ongoing research and concerted action to confront this pressing environmental dilemma.
