Case Studies on Microplastic Contamination with a Focus on the Impact of the COVID‐19 Pandemic

The global pandemic, COVID-19 has significantly exacerbated the global issue of microplastic (MP) pollution, introducing new challenges and highlighting existing vulnerabilities within aquatic ecosystems. This chapter explores the multifaceted impact of increased plastic waste associated with pandemic-related activities, such as the increased use and subsequent disposal of personal protective equipment, disposable packaging, and various hygiene products. The pathways through which these plastics enter aquatic environments, their degradation into MPs, and the subsequent effects on marine and freshwater species were examined. Despite the predominantly negative consequences, such as physical harm, chemical toxicity, and habitat disruption, the pandemic has also led to some positive developments. Increased scientific research and public awareness have advanced our understanding of MP pollution and driven innovative solutions. Policy responses and regulatory changes have been prompted by the visible surge in plastic waste, aiming to mitigate long-term environmental impacts. This chapter comprehensively analyzes MP pollution's detrimental and beneficial aspects during the COVID-19 pandemic, emphasizing the need for sustained efforts in plastic waste management and environmental conservation. Through detailed case studies and current research, the critical need for global cooperation and innovative strategies are highlighted to address the ongoing threat of MP pollution.
