Generation, Distribution, and Disposal of Marine Microplastic Debris
AI summary Read the abstract
This chapter reviews existing research on ocean microplastic pollution, covering where it comes from, how it travels and breaks down in the environment, and its effects on marine life and human health. It also discusses wastewater treatment methods, policy efforts, and international cooperation aimed at managing this pollution, and points to areas needing further study.
Marine microplastic pollution has emerged as a persistent threat to the ocean health around the globe due to the generation, distribution, and inadequate disposal of plastic materials. This chapter deals with the sources, transport mechanisms, and environmental fate of microplastics. Ecological and human health impacts are discussed along with the spatial and temporal variability and the policy responses. International collaboration in microplastic pollution management is addressed, along with the advanced techniques for the management of wastewater to prevent the release of microplastics. Actionable management strategies are considered, and the areas of future research are highlighted at the end. Overall, the chapter projects the urgent need for coordinated, data-driven strategies to address this ever-increasing environmental challenge.
