Available in PDF, EPUB and Kindle. Book excerpt: In the last decade, issues related to pollution from microplastics in all environmental compartments and the associated health and environmental risks have been the focus of intense social, media, and political attention worldwide. The assessment, quantification, and study of the degradation processes of plastic debris in the ecosystem and its interaction with biota have been and are still the focus of intense multidisciplinary research. Plastic particles in the range from 1 to 5 mm and those in the sub-micrometer range are commonly denoted as microplastics and nanoplastics, respectively. Microplastics (MPs) are being recognized as nearly ubiquitous pollutants in water bodies, but their actual concentration, distribution, and effects on natural waters, sediments, and biota are still largely unknown. Contamination by microplastics of agricultural soil and other environmental areas is also becoming a matter of concern. Sampling, separation, detection, characterization and evaluating the degradation pathways of micro- and nano-plastic pollutants dispersed in the environment is a challenging and critical goal to understand their distribution, fate, and the related hazards for ecosystems. Given the interest in this topic, this Special Issue, entitled "Microplastics Degradation and Characterization", is concerned with the latest developments in the study of microplastics.

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 309 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 A critical comparison of the main characterization techniques for microplastics identification in an accelerated aging laboratory experiment written by Glaucia Peregrina Olivatto and published by OAE Publishing Inc.. This book was released on 2024-02-06 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many studies have reported the occurrence of microplastics in different environmental compartments, through the description of their morphological characteristics and chemical identification, obtained mainly by spectroscopic techniques. However, the scientific community still lacks the implementation of standardized analytical methods that aim to assess not only the identification of the particle, but also its stage of degradation. It is understood that this information would be extremely useful in helping elucidate the main sources of pollution and contributing to strategies and mitigating measures for the management of solid waste and microplastics in the environment. In this respect, the aim of this study was to evaluate the efficiency of Fourier-transform infrared spectroscopy, Raman spectroscopy, carbon elemental analysis coupled with mass spectrometry, and scanning electron microscopy with energy dispersive X-ray spectrometry for the characterization of virgin and aged polyethylene and polypropylene microplastics samples. The degraded samples were subjected to accelerated aging in a QUV chamber in accordance with American standard for measuring accelerated weather testing (ASTM G-154). This work discusses the efficiency and limitations of each technique for the detailed chemical characterization of microplastic samples collected from the environment.

Download or read book Analysis of Nanoplastics and Microplastics in Food written by Leo M.L. Nollet and published by CRC Press. This book was released on 2020-12-02 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world’s ever increasing use of plastics has created large areas of floating plastic waste in the oceans—so-called plastic soup. This floating plastic debris is gradually fragmenting into smaller particles which eventually become microplastics, and even nanoplastics. Analysis of Nanoplastics and Microplastics in Food compiles data on nanoplastics and microplastics in food. To date, there is some data on this, particularly for the marine environment. Fish show high concentrations, but because microplastics are mostly present in the stomach and intestines, they are usually removed and consumers are not exposed. But in crustaceans and bivalve molluscs like oysters and mussels, the digestive tract is consumed, so there is some exposure. Microplastics have also been reported in honey, beer, and table salt. Key Features: Discusses sampling and analysis of nano- and microplastics Details the impacts of plastic residues in diverse compartments of the environment Includes a discussion of microplastics in freshwater Discusses interactions of microplastics and POPs This book brings to light the reality—and dangers—of microplastics in food. Pollutants like polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) can accumulate in microplastics. Some studies suggest that, after consuming microplastics in food, these substances may transfer into tissues. So, it is important to estimate the average intake. Since engineered nanoparticles (from different types of nanomaterials) can enter human cells, this reality can pose consequences for human health.

Book excerpt: The 8th Edition of the UN Environment Programme flagship report, The UNEP Year Book 2011, examines global emerging issues and provides the latest environmental science. it also highlights major environmental events and developments over the past year, and presents the most recent data and indicator trends. The ocean has become a global repository for much of the waste we produce. Scientists are concerned that plastic debris in the ocean can transport toxic substances which may end up in the food chain, causing potential harm to ecosystems and human health. The Year Book also explores the wider implications of the use of phosphorus in food production. Phosphorus is an essential nutrient whose supply is limited. Since demand for fertilizer in agriculture rocketed in the 20th century, large amounts of phosphorus are flowing into the environment. New perspectives are also emerging on how biodiversity conservation can be integrated in forest management. Forests are receiving increasing attention, not least because of their role in climate change mitigation. Halting loss of forest biodiversity is essential if forests are to adapt to mounting pressures, including climate change and pest outbreaks. The Year Book's overview of events and developments during 2010 shows how cutting edge science reveals new opportunities to mitigate climate change while improving air quality. Stimulated by technological innovation and green investments, renewable energy supply is growing rapidly. This and other developments are summarized in key environmental indicators that present the latest data and trends For The global environment.
