Download or read book Freshwater Microplastics written by Martin Wagner and published by Springer. This book was released on 2017-11-21 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Microplastic in the Environment Pattern and Process written by Michael S. Bank and published by Springer Nature. This book was released on 2021-10-09 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Despite the fact that such pollution might have mainly started out from the sea, it is now in lakes, rivers, ponds and even drinking water. This book presents as overview of microplastics in freshwater environments in different regions around the world. It discusses the ecotoxicological effects of microplastics, the removal/remediation techniques of microplastics and the role of water/wastewater treatment plants in spreading microplastics. This book is a valuable resource, covering wide aspects of microplastics from sources, detection and characterization to removal and their fate in treatment plants.
Download or read book The Transformations and Fate of Nanoplastics and Microplastics in Aquatic Environments written by Olubukola Alimi and published by . This book was released on 2022 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "The risks posed by plastic debris to the environment and human health, depend on several factors, including their 1) tendency to remain colloidally stable in the aquatic environment, 2) transport potential in natural aquatic environments, including the subsurface, and 3) potential to act as vectors for other pollutants in ecosystems. The scientific literature was critically reviewed and used to determine estimates of plastic loads and pathways in different environmental compartments. The key factors controlling the aggregation, deposition and contaminant cotransport of microplastics in the aquatic environment, as well as important knowledge gaps were identified and critically analyzed. From the critical data synthesis, it was shown that the rubbery polymer, polyethylene, generally has a higher contaminant sorption capacity than other synthetic plastic types. The next part of this thesis investigated the role of climate and temperature cycling on nanoplastic transport. It is shown that by ignoring the effect of freeze-thaw, a key component of cold climate regions, previous conclusions on nanoplastic mobility might have been overestimated. Controlled laboratory experiments were used to show that exposure of nanoplastics to repeated freeze-thaw cycles, such as those experienced in cold climates will lead to aggregation and reduced transport even in the presence of natural organic matter in soils and subsurface environments. In another study, the factors and mechanisms by which different plastic sizes interact with NOM (humic acid, fulvic acid and alginate) in simple and complex artificial and natural environmental matrices were investigated and compared. It was shown that the different organic molecules will interact with the different plastics in a size-specific manner. In the absence of NOM, the minimum CaCl2 concentration needed to destabilize the particle suspension is insensitive to plastic size. Although the presence of the polysaccharide alginate enhanced aggregation in CaCl2, it had no effect/stabilized nanoplastics in a complex ionic matrix. While there were no significant differences in the attachment efficiencies of both bare nanoplastics at the CCC (CaCl2) and in artificial seawater, the larger nanoplastics were more stable than the smaller ones in a natural seawater matrix. A critical literature review reveals that only ten percent of laboratory studies investigating the effects of microplastic pollution in ecosystems have used environmentally relevant (aged) particles. An extensive synthesis of laboratory effect studies in the context of environmentally relevant protocols for weathered microplastics, nanoplastics and leachates is presented which also provides a framework for method harmonization. Hence, in a final experimental study, the impact of environmental weathering on the physicochemical properties of microplastics originating from single-use plastics was investigated using a range of techniques. The impacts of these physicochemical changes on microplastic transport and contaminant facilitated transport are examined. Changes to the surface chemistry, polarity, morphology, and density all impacted the fate of the microplastics. The experimental results show that aging reduced the sorption of a hydrophobic contaminant, triclosan, to the microplastics while both pristine and aged plastics partially desorb this contaminant. Measurements of microplastic settling velocity show that aging significantly increased the mobility of the microplastics. The combined experimental findings and transport simulations imply that pristine plastics will undergo long range transport and may facilitate the mobility of hydrophobic contaminants in surface waters. Overall, these results advance our knowledge of how different environmental conditions will influence microplastic fate and transport and provide fundamental and mechanistic understanding of factors affecting microplastics stability in aquatic environments"--

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Fate and Transport of Nanoscale Plastics in the Aquatic Environment written by Mehnaz Shams and published by . This book was released on 2019 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plastic debris is common in the environment due to its durability and widespread use. Large plastic debris can be eventually broken down to microplastics and nanoscale plastics which are recently getting attention. Moreover, their persistent nature and long residence time enable these microplastics and nanoscale plastics to accumulate in the environment and be susceptible to various transformation processes influencing their aggregation, deposition, and transport behavior. While microplastics have been investigated extensively, fate and transport of nanoscale plastics are still unknown. The overall goal of this research is to identify the fundamental mechanisms involved in the stability of nanoscale plastics in the presence of NaCl, CaCl2, and MgCl2 at different ionic strength, their transport through filtration media and their interactions with different surfaces (silica, natural organic matter (NOM) surfaces) using the quartz crystal microbalance with dissipation monitoring (QCM-D). The research specifically focused on the polyethylene and polystyrene nanoscale plastic, commonly detected in the environment. Stability studies showed that CaCl2 (critical coagulant concentration (CCC 0.1 mM) destabilized polyethylene nanoscale plastics more aggressively than NaCl (CCC 80 mM) and MgCl2 (CCC 3 mM). Transport studies showed that the mobility of both nanoscale plastics was higher than microplastics through porous media. Mobility decreased with increasing ionic strength and increasing particle size and this transport was mainly governed by secondary energy minimum. Furthermore, polystyrene was three-fold more mobile than polyethylene at the same ionic strength due to its size and surface charge. Conversely, the presence of NOM improved the stability and increased the mobility of both nanoscale plastics in water due to steric repulsion. QCMD studies showed higher interactions of both nanoscale plastics with NOM-coated surfaces than silica surfaces, with polystyrene having at least five-fold higher deposition than polyethylene on both surfaces. Combined results indicate that size and surface functionalization of nanoscale plastics will play a major role in their fate in aquatic environment, which will also be governed by NOM-coated surfaces. Overall, findings from this research will be useful in predicting fate, transport and removal of nanoscale plastics from the aquatic environment for the safety of public health and the environment.
Download or read book Reckoning with the U S Role in Global Ocean Plastic Waste written by National Academies of Sciences, Engineering, and Medicine and published by . This book was released on 2022-09 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: An estimated 8 million metric tons (MMT) of plastic waste enters the world's ocean each year - the equivalent of dumping a garbage truck of plastic waste into the ocean every minute. Plastic waste is now found in almost every marine habitat, from the ocean surface to deep sea sediments to the ocean's vast mid-water region, as well as the Great Lakes. This report responds to a request in the bipartisan Save Our Seas 2.0 Act for a scientific synthesis of the role of the United States both in contributing to and responding to global ocean plastic waste. The United States is a major producer of plastics and in 2016, generated more plastic waste by weight and per capita than any other nation. Although the U.S. solid waste management system is advanced, it is not sufficient to deter leakage into the environment. Reckoning with the U.S. Role in Global Ocean Plastic Waste calls for a national strategy by the end of 2022 to reduce the nation's contribution to global ocean plastic waste at every step - from production to its entry into the environment - including by substantially reducing U.S. solid waste generation. This report also recommends a nationally-coordinated and expanded monitoring system to track plastic pollution in order to understand the scales and sources of U.S. plastic waste, set reduction and management priorities, and measure progress.
