Available online: https://pub.norden.org/temanord2020-528/# This report provides both field and impact data on microlitter pollution in the arctic marine environment of Svalbard and Greenland. Microlitter concentrations and characteristics were determined in marine sediments and biota in relation to local sources. Higher concentrations and diversities were found closer to human settlements and sites where lost/dumped fishing gear accumulated. Thus, local microlitter sources were found to be present in the Arctic. The experimental studies on effects of microlitter on feeding rate, microplastic ingestion, respiration and locomotion activity in an arctic amphipod, confirmed previous studies showing effects only at very high concentrations, not yet relevant in the arctic environment. The relatively low field concentrations of microlitter found in this study should be regarded as a ‘window of opportunity’ to act to at least reduce local pollution.

Available online: https://pub.norden.org/temanord2022-568/ The occurrence of abandoned, lost, and discarded fishing gear (ALDFG) in aquatic environments contributes both to environmental and socioeconomic impacts. In nature, discarded fishing gear contributes to pollution by macro- and microplastics and harmful chemicals as well as to the degradation of habitats. This study compiles information from the Nordic countries on the quantity and composition of lost fishing gear, originating mainly from sport- and recreational fishing activities. The study also considers the occurrence of harmful chemicals associated with the lost fishing gear and the potential impact of these chemicals on the aquatic environment. Suggestions on how to prevent further losses and mitigate negative impact of lost fishing gear are also provided.

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 book offers a detailed presentation of the principles and practice of life cycle impact assessment. As a volume of the LCA compendium, the book is structured according to the LCIA framework developed by the International Organisation for Standardisation (ISO)passing through the phases of definition or selection of impact categories, category indicators and characterisation models (Classification): calculation of category indicator results (Characterisation); calculating the magnitude of category indicator results relative to reference information (Normalisation); and converting indicator results of different impact categories by using numerical factors based on value-choices (Weighting). Chapter one offers a historical overview of the development of life cycle impact assessment and presents the boundary conditions and the general principles and constraints of characterisation modelling in LCA. The second chapter outlines the considerations underlying the selection of impact categories and the classification or assignment of inventory flows into these categories. Chapters three through thirteen exploreall the impact categories that are commonly included in LCIA, discussing the characteristics of each followed by a review of midpoint and endpoint characterisation methods, metrics, uncertainties and new developments, and a discussion of research needs. Chapter-length treatment is accorded to Climate Change; Stratospheric Ozone Depletion; Human Toxicity; Particulate Matter Formation; Photochemical Ozone Formation; Ecotoxicity; Acidification; Eutrophication; Land Use; Water Use; and Abiotic Resource Use. The final two chapters map out the optional LCIA steps of Normalisation and Weighting.

This unique textbook takes a broad look at the rapidly expanding field of freshwater microbiology. Concentrating on the interactions between viruses, bacteria, algae, fungi and micro-invertebrates, the book gives a wide biological appeal. Alongside conventional aspects such as phytoplankton characterisation, seasonal changes and nutrient cycles, the title focuses on the dynamic and applied aspects that are not covered within the current textbooks in the field. Complete coverage of all fresh water biota from viruses to invertebrates Unique focus on microbial interactions including coverage of biofilms, important communities on all exposed rivers and lakes. New information on molecular and microscopical techniques including a study of gene exchange between bacteria in the freshwater environment. Unique emphasis on the applied aspects of freshwater microbiology with particular emphasis on biodegradation and the causes and remediation of eutrophication and algal blooms.

Wetland ecosystems maintain a fragile balance of soil, water, plant, and atmospheric components in order to regulate water flow, flooding, and water quality. Marginally covered in traditional texts on biogeochemistry or on wetland soils, Biogeochemistry of Wetlands is the first to focus entirely on the biological, geological, physical, and chemical
