With a food safety focus, a scientific literature review was conducted to characterize the current understanding about the effects of microplastics on the gut microbiome and potential health implications. The main aspects analysed are (1) the effects of microplastics on the composition, diversity and function of gut microbiome using in vito and in vivo models; (2) health implications resulting from the microplastic–microbiome interactions and underlying mechanisms; (3) the establishment of causality; and (4) influence of the gut microbiome on microplastic biodegradation. The research was also scoped to identify current gaps, limitations and needs for the eventual consideration of microbiome-related data in chemical risk assessment. With this work, ESF contributes to the FAO global programme on the impact of food systems on NCDs and obesity, by understanding the potential health implications of gut microbiome–microplastic interactions. The outcomes will provide information which can be used to improve food safety policies.

This book is open access under a CC BY 4.0 license. This volume focuses on microscopic plastic debris, also referred to as microplastics, which have been detected in aquatic environments around the globe and have accordingly raised serious concerns. The book explores whether microplastics represent emerging contaminants in freshwater systems, an area that remains underrepresented to date. Given the complexity of the issue, the book covers the current state-of-research on microplastics in rivers and lakes, including analytical aspects, environmental concentrations and sources, modelling approaches, interactions with biota, and ecological implications. To provide a broader perspective, the book also discusses lessons learned from nanomaterials and the implications of plastic debris for regulation, politics, economy, and society. In a research field that is rapidly evolving, it offers a solid overview for environmental chemists, engineers, and toxicologists, as well as water managers and policy-makers.

This second edition of Microplastic Contamination in Aquatic Environments: An Emerging Matter of Environmental Urgency presents 14 chapters, through which a team of global, expert contributors cover a full range of microplastic research. The first chapter describes the general patterns for sources, occurrence, and transport of microplastics to lead off the book. The next batch of chapters covers sampling analytical methods for quantifying microplastics in the environment, followed by chapters addressing the association of chemicals with microplastics. A large cluster of chapters focus on the fate and transport of microplastics in wastewater treatment plants, freshwater systems, marine environment, terrestrial settings, and riverine runoff that connects terrestrial and marine systems. The next few chapters examine biotransport and effects of microplastics in organisms. The last two chapters are dedicated to two emerging research areas: nanoplastics in the environment and management strategies for global plastic pollution. Outlooks for future research to better understand the situation and further improvements of microplastic research are also covered. In the 6 years since the previous edition published, this fast-moving area has evolved, and the contents of this revision reflect that. There are numerous brand-new chapters, chapters that have been revised, and chapters that have been completely refocused. This book provides an overview of microplastics research. It is a guide for researchers to better understand the occurrence of microplastics. Ideally, this book provides basic background knowledge of microplastics for oceanographers, ecologists, and climatologists. Provides an overview of the advantages and disadvantages of different methods for sampling, identification, and enumeration of microplastics Contains contributions from world experts with a diverse range of backgrounds, all brought together by a well-known, experienced editor Presents information on microplastics in a unified place, with easy access for the reader

This open access book examines global plastic pollution, an issue that has become a critical societal challenge with implications for environmental and public health. This volume provides a comprehensive, holistic analysis on the plastic cycle and its subsequent effects on biota, food security, and human exposure. Importantly, global environmental change and its associated, systems-level processes, including atmospheric deposition, ecosystem complexity, UV exposure, wind patterns, water stratification, ocean circulation, etc., are all important direct and indirect factors governing the fate, transport and biotic and abiotic processing of plastic particles across ecosystem types. Furthermore, the distribution of plastic in the ocean is not independent of terrestrial ecosystem dynamics, since much of the plastic in marine ecosystems originates from land and should therefore be evaluated in the context of the larger plastic cycle. Changes in species size, distribution, habitat, and food web complexity, due to global environmental change, will likely alter trophic transfer dynamics and the ecological effects of nano- and microplastics. The fate and transport dynamics of plastic particles are influenced by their size, form, shape, polymer type, additives, and overall ecosystem conditions. In addition to the risks that plastics pose to the total environment, the potential impacts on human health and exposure routes, including seafood consumption, and air and drinking water need to be assessed in a comprehensive and quantitative manner. Here I present a holistic and interdisciplinary book volume designed to advance the understanding of plastic cycling in the environment with an emphasis on sources, fate and transport, ecotoxicology, climate change effects, food security, microbiology, sustainability, human exposure and public policy.

This book describes how man-made litter, primarily plastic, has spread into the remotest parts of the oceans and covers all aspects of this pollution problem from the impacts on wildlife and human health to socio-economic and political issues. Marine litter is a prime threat to marine wildlife, habitats and food webs worldwide. The book illustrates how advanced technologies from deep-sea research, microbiology and mathematic modelling as well as classic beach litter counts by volunteers contributed to the broad awareness of marine litter as a problem of global significance. The authors summarise more than five decades of marine litter research, which receives growing attention after the recent discovery of great oceanic garbage patches and the ubiquity of microscopic plastic particles in marine organisms and habitats. In 16 chapters, authors from all over the world have created a universal view on the diverse field of marine litter pollution, the biological impacts, dedicated research activities, and the various national and international legislative efforts to combat this environmental problem. They recommend future research directions necessary for a comprehensive understanding of this environmental issue and the development of efficient management strategies. This book addresses scientists, and it provides a solid knowledge base for policy makers, NGOs, and the broader public.
