Download or read book Removal of Emerging Contaminants Through Microbial Processes written by Maulin P Shah and published by Springer Nature. This book was released on 2020-10-14 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: The abundance of organic pollutants found in wastewater affect urban surface waters. Traditional wastewater management technologies focus on the removal of suspended solids, nutrients and bacteria, however, new pollutants such as synthetic or naturally occurring chemicals are often not monitored in the environment despite having the potential to enter the environment and cause adverse ecological and human health effects. Collectively referred to as "emerging contaminants," they are mostly derived from domestic activities and occur in trace concentrations ranging from pico to micrograms per liter. Environmental contaminants are resistant to conventional wastewater treatment processes and most of them remain unaffected, causing contamination of receiving water. This in turn leads to the need for advanced wastewater treatment processes capable of removing environmental contaminants to ensure safe fresh water sources. This book provides an up-to-date overview of the current bioremediation strategies, including their limitations, challenges and their potential application to remove environmental pollutants. It also introduces the latest trends and advances in environmental bioremediation, and presents the state-of-the-art in biological and chemical wastewater treatment processes. As such, it will appeal to researchers and policy-makers, as well as undergraduate and graduate environmental sciences students.

Download or read book Evaluation of Environmental Contaminants and Natural Products A Human Health Perspective written by Ashita Sharma and published by Bentham Science Publishers. This book was released on 2019-06-10 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unbridled urbanization and development of natural land resources has led to the degradation of our surrounding environment. The air that we breathe, the water we drink and the food we eat is at risk of being contaminated with a plethora of chemical pollutants, some of them being potentially carcinogenic. This presents a challenge to human health. This book attempts to address this challenge in two parts which represent two different approaches. The first part of the book summarizes the alarming effects of environmental contaminants. Various studies depicting the direct relationship of environmental contaminants with cancer incidence have been referenced. Scientific studies have established an inverse relation between cancer and ingestion of dietary phytoconstituents (phytochemicals) in the form of fruits, vegetables and botanical herbs. Plant products as dietary supplements can suppress contaminant toxicity by regulating the resulting reactive species and also by assisting their bodily excretion through Phase 1 and Phase 2 enzyme metabolism. The second part of the book, shifts focus to phytoconstituents which, if included in diet, can prevent the harmful effects of pollutants. The text references numerous studies showing the anti-mutagenic, anti-genotoxic and anti-carcinogenic potential of many plant products. The combination of information about contemporary issues of carcinogenic contaminants in the environment coupled with the references to relevant studies in this handbook will enlighten readers studying courses in environmental chemistry, toxicology, botany, and ecology about environmental toxins and help them understand specific dietary measures known to reduce the toxic impact. Researchers in the field of nutrition can also benefit from the information provided.
Download or read book Sustainable Management of Environmental Contaminants written by Tariq Aftab and published by Springer Nature. This book was released on 2022-11-04 with total page 557 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental contaminants are chemicals that accidentally or deliberately enter the environment, often, but not always, as a result of human activities. Some of these contaminants may have been manufactured for industrial use, and because they are very stable, they do not break down easily. If released to the environment, these contaminants may enter the food chain. Other environmental contaminants are naturally occurring chemicals, but industrial activity may increase their mobility or increase the amount available to circulate in the environment, allowing them to enter the food chain at higher levels than would otherwise occur. Environmental contaminants influence the physiological cell reactions at different and heterogeneous basics and lead to altering in normal cell function primarily at the molecular and biochemical level. Molecular responses to such common environmental stresses have been studied intensively over the last few years, in which there is an intricate network of signaling pathways controlling perception of these environmental stress signals, the generation of second messengers and signal transduction. Recent advances in many areas of plant and microbial research, including genotyping, make scientists optimistic that valuable solutions will be found to allow deployment/commercialization of strategies better able to tolerate these environmental stresses. Environmental remediation was historically viewed as an inherently sustainable activity, as it restores contamination; however, researchers and practitioners are increasingly recognizing that there can be substantial environmental footprints and socioeconomic costs associated with remediation. Sustainability is an imperative in the emerging green and sustainable remediation movement, which is reshaping the entire remediation industry. Understanding the significant roles of sustainable or eco-friendly approaches in mitigating environmental contaminants, the current subject has recently attracted the attention of scientists from across the globe. This comprehensive volume “Sustainable Management of Environmental Contaminants: Eco-friendly Remediation Approaches" highlights the various prospects involved in current scenario. The current volume comprises the chapters from diverse areas dealing with biotechnology, microbial technology, nanotechnology, molecular biology, green and sustainable remediation, etc. I am hopeful that this volume will furnish the requisite of all those who are working or have interest in the current topic.

Download or read book Phytoremediation written by Lee Newman and published by Springer Nature. This book was released on 2023-02-13 with total page 620 pages. Available in PDF, EPUB and Kindle. Book excerpt: The accumulation of large amounts of contaminants occurs in the environment due to industrialization and various other anthropogenic activities. Contaminants ultimately affect human health worldwide. Organic, inorganic, and radioactive substances are the prevalent forms of environmental contaminants and their complete remediation in soils and sediments is rather a difficult task. Concerns of their toxicities led to the emphasis on development of effective techniques to assess the presence and mobility of contaminants in air, water, and soil. Furthermore, the ever-increasing concentration of toxic pollutants in the environment is considered a serious threat to plant, animal, human, and environmental health. Many technologies are in use to clean and eliminate hazardous contaminants from the environment; however, these technologies can be costly, labor intensive, and often distressing to the general public. Phytoremediation is a simple, cost effective, environmentally friendly and fast-emerging new technology for eliminating toxic contaminants from different environments. Phytoremediation refers to the natural ability of certain plants and their associated microbiome (including hyper-accumulators or bio-accumulators) to remove, degrade, or render contaminants harmless. Through this technique, certain species of plants flourish by accumulating contaminants present in the environment. The unique and selective uptake capabilities of plant root and shoot systems, effective translocation, bioaccumulation, and contaminant degradation capabilities of the accumulator plants are utilized in phytoremediation techniques. Phytotechnologies involving the use of plants for contaminant removal gained importance during the last two decades and phytoremediation technology became an effective tool for environmental detoxification because of plants ability to accumulate the contaminants at very high concentrations. Phytoremediation strategies can remove, degrade, or stabilize inorganic and organic contaminants entering a multitude of ecosystems using green plants and their associated microbial communities. The development and use of phytotechnologies continues to move forward at a steady pace. Researchers recognize the potential of phytoremediation to offer a green, cost effective, eco-friendly and feasible application to address some of the world’s many environmental challenges. This book provides significant information to add to the previous volumes published on the topic and can serve as the foundation for the development of new applications that feature the integration of modern research discoveries into new methods to remediate contaminated ecosystems. Moreover, this volume brings recent and established knowledge on different aspects of phytoremediation and nano-phytoremediation, providing this information in a single source that offers a cutting-edge synthesis of scientific and experiential knowledge on polluted environments that is useful for policy makers, practitioners and scientists, and engineers. Phytoremediation: Management of Environmental Contaminants, Volume 7 highlights the various prospects that are involved in current global phytoremediation research. This book delivers a content-rich source to the reader and can act as a platform for further research studies. It should meet the needs of all researchers working in, or have an interest in this particular field.

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.
