Evaluating wastewater effluent as a source of microplastics in environmental samples
AI summary Read the abstract
This book chapter evaluates wastewater effluent as a source of microplastics in environmental samples, reviewing evidence of microplastic presence in freshwater systems, wastewater treatment plants, and associated biota. Researchers found that wastewater treatment plants are a significant conduit for microplastics into freshwater and marine environments despite their partial removal capacity.
This book covers the topic of microplastics in water and wastewater. The chapters start with introductory issues related to the growing interest in the scientific community on microplastics and the human water cycle and point out where the microplastics could interact with water. The subsequent chapters examine evidence of the microplastic presence in freshwater, such as in both rivers and lakes, in freshwater biota, and hazardous chemicals associated with microplastics in such systems.Another set of chapters discuss the presence of microplastics in wastewater: their sources; their transfer through a wastewater treatment plant; the concentration of microplastics in effluents throughout the world; the plastic biomedia used in wastewater treatment plants and the effect on the surrounding environment of effluent wastewater pipes. These chapters also discuss the sampling methods, the sample treatment and analysis techniques used so far for microplastics in wastewater. Additionally, the presence of microplastics in sewage sludge and in soils irrigated with wastewater or fertilized with sludge are discussed. The possible impact of plastics and their additives on plants, microalgae, and humans are reviewed and presented in a critical way. Finally, a chapter summarizes all the relevant regulations and initiatives that point to the necessity of a global directive for the protection of the environment from plastic and microplastic pollution.The topic of microplastics in freshwater systems and in wastewater has scarcely been studied and requires more attention. Microplastics in Water and Wastewater aims to bring these initial findings to the attention of a broader audience and especially to operators and managers of freshwater and wastewater systems. It will also be helpful to people already aware of the marine debris problem to understand the sources of microplastics in the oceans, from freshwater systems and wastewater treatment plants."All in all, the book is recommended for researchers and policymakers in the fields of environmental chemistry, civil engineering, city planning, waste management and toxicology. Furthermore, it is also worthwhile for those who are concerned about the effects of microplastics on biota and on humans."Professor Hideshige Takada, Laboratory of Organic Geochemistry (LOG), Tokyo University of Agriculture and Technology, International Pellet WatchISBN: 9781789060027 (print)ISBN: 9781789060034 (eBook)ISBN: 9781789060041 (ePUB)

Evaluating wastewater effluent as a source of microplastics in environmental samples
AI summary Read the abstract
This book chapter reviews how microplastics enter freshwater systems and wastewater treatment plants, and how these plants serve as both a partial barrier and a pathway for microplastics reaching rivers and oceans. Understanding wastewater as a vector is crucial for developing interventions that prevent microplastics from reaching ecosystems.
Wastewater treatment plant effluent as a source of microplastics: review of the fate, chemical interactions and potential risks to aquatic organisms
AI summary Read the abstract
This review examines wastewater treatment plant effluent as a source of microplastics entering aquatic environments. The study found that even though treatment plants remove most microplastics, the small amounts remaining in effluent may still contribute significantly to environmental contamination, and the chemical interactions between microplastics and other pollutants in wastewater raise additional ecological concerns.

This book provides comprehensive coverage of microplastics in water and wastewater systems, emphasizing that while marine environments have received most attention, freshwater systems and wastewater treatment plants are equally important sources and sinks of microplastic contamination.
Wastewater treatment plants as a source of microplastics to the environment.
AI summary Read the abstract
This study was the first to characterize the contribution of a wastewater treatment plant to microplastic pollution in a receiving water body, confirming that plants are significant sources of microplastics despite removing the majority of particles. The findings highlight the need to upgrade treatment processes or implement new technologies specifically targeting microplastic removal.
