Surface Chemistry of Carbon Capture: Climate Change Aspects provides comprehensive and up-to-date literature on carbon capture and storage (CCS) technology and delineates the surface chemistry of this process. Mankind is dependent on energy from gas, oil, coal, atomic energy, and various other sources. In all fossil fuel combustion processes, carbon dioxide (CO2) is produced (ca. 25 Gt/year). In the past few decades, we have observed a constant increase in CO2 content in the air (currently ca. 400 ppm [0.04%]). This book discusses the technology related to carbon (i.e., CO2) capture and sequestration (CCS) from fossil fuel energy plants, which is considered an important means of CO2 control. It also covers the adsorption/absorption processes of CO2 on solids and similar procedures to help address growing climate change concerns.
Plant diseases are a serious threat to food production. This unique volume provides the fundamental knowledge and practical use of B.subtilis as a promising biocontrol agent. In order to replace chemical pesticides, one possibility is microbial pesticides using safe microbes. Bacillus subtilis is one of several candidates. Screening of the bacterium, the application of plant tests, clarification of its suppressive mechanism to plant pathogens and engineering aspects of suppressive peptides production are presented here. The author illustrates how B. subtilis is far more advantageous than, for example, Pseudomonas in biocontrol and can be considered as an useful candidate. Features: Bacterium B. subtilis suppresses many plant pathogens and is a biocontrol agent to replace chemical pesticides The book presents the bacterium's suppressive mechanism to plant pathogens, and engineering aspects of suppressive peptides production Biological control of plant disease plays an important role in sustainable agricultural production practices and is expected to replace agricultural chemicals
Phosphorus is an essential plant nutrient, but global population growth has dramatically reduced the availability of phosphorus fertilizer resources. Despite this scarcity, there remain numerous problems associated with the excessive and inappropriate use of phosphorus leading to non-point source pollution and eutrophication of natural waters. Identifying appropriate systems for managing soil phosphorus and reducing the risks of eutrophication are needed to minimize the environmental risks. This book focuses on the availability and recycling of phosphorus; regulatory and policy issues of sustainable phosphorus use; and water quality management in agroecosystems pertaining to phosphorus. Sections are dedicated to global phosphorus reserves; cycling and pathways of phosphorus; phosphorus in agriculture; human dimensions and policy intervention; and research and development priorities. Phosphorus is a finite but crucial resource and is an essential element to all life. Sub-optimal availability and nutrient imbalance in the root zone can adversely impact plant growth, and the quality of food and feed grown on these soils. However, the proven reserves of phosphorus can hardly be adequate for a few centuries only. Yet, its misuse and mismanagement has caused severe problems of eutrophication of water and pollution of the environment. Thus, judicious management of soil phosphorus is essential. This volume is specifically devoted to availability and recycling of phosphorus, regulatory/policy issues of sustainable use of phosphorus, and management in agroecosystems in the context of maximizing the use efficiency and minimizing the environmental risks of water quality.
Trace Elements in Abiotic and Biotic Environments helps readers understand the fundamental principles and phenomena that control the transfer of trace elements. This book describes the occurrence and behavior of trace elements in rocks, soil, water, air, and plants, and also discusses the anthropogenic impact to the environment. In addition, it covers the presence of trace elements in feeds, as either contaminants or as nutritional or zootechnical additives, and their transfer across the food chain to humans. Also discussed is international legislation on trace elements for both micronutrients and contaminants in soil and plant food. A special focus is placed on the human health effects of both trace element deficiency and excess. All trace elements are covered-from aluminum to zirconium-as well as rare-earth elements (actinides and lanthanides).
One of the fundamental principles of green chemistry is to design chemical products that minimize adverse consequences to human health and the environment. While chemists have been designing molecules for 200 years to have a limitless range of commercial applications, little or no attention has been given to developing commercial chemicals while avoiding hazards and toxicity. This book is the first to provide chemists with useful, practical guidance on how to minimize or avoid a wide range of hazards. Building on the insights gained from the pharmaceutical industry over the past 25 years on how to create desirable biological effects, the authors demonstrate how to avoid undesirable biological effects by design.
Agriculture is one of the oldest and most global human enterprises, and as the world struggles with sustainable practices and policies, agricultural chemistry has a clear role to play. This book highlights the ways in which science in agriculture is helping to achieve global sustainability in the 21st century, and demonstrates that this science can and should be a leading contributor in discussion on environmental science and chemistry. The four drivers of this subject are presented, those being economic, environmental, regulatory and scientific, and help showcase agricultural chemistry as a dynamic subject that is contributing to this necessity of global sustainability in the 21st century.
The Congress "Arsenic in the Environment" offers an international, multi- and interdisciplinary discussion platform for research and innovation aimed towards a holistic solution to the problem posed by the environmental toxin arsenic, with significant societal impact. The Congress has focused on cutting edge and breakthrough research in physical, chemical, toxicological, medical, agricultural and other specific issues on arsenic across a broader environmental realm. The Biennial Congress "Arsenic in the Environment" was first organized in Mexico City (As2006) followed by As2008 in Valencia (Spain), As2010 in Tainan (Chinese Taiwan), As2012 in Cairns (Australia), As2014 in Buenos Aires (Argentina) and As2016 in Stockholm (Sweden). The 7th International Congress As2018 was held July 1-6, 2018, in Beijing, P. R. China and was entitled Environmental Arsenic in a Changing World. The Congress addressed the broader context of arsenic research aligned on the following themes: Theme 1: Arsenic Behaviour in Changing Environmental Media Theme 2: Arsenic in a Changing Agricultural Ecosystem Theme 3: Health Impacts of Environmental Arsenic Theme 4: Technologies for Arsenic Immobilization and Clean Water Blueprints Theme 5: Sustainable Mitigation and Management Arsenic in drinking water (mainly groundwater) has emerged as an issue of global health concern. During last decade, the presence of arsenic in rice, possibly also other food of plant origins, has attained increasing attention. This is particularly true in the Asian countries, where the use of high arsenic groundwater as source of irrigation water and drinking water has been flagged as severe health concern. This has been accentuated by elevating arsenic concentrations in deep groundwater recharged from shallow high arsenic groundwater, which may have further detrimental effects on public health. Notably, China has been in the forefront of research on arsenic biogeochemical cycling, health effects of arsenic, technologies for arsenic removal, and sustainable mitigation measures. The Congress has attracted professionals involved in different segments of interdisciplinary research on arsenic in an open forum, and strengthened relations between academia, research institutions, government and non-governmental agencies, industries, and civil society organizations to share an optimal ambience for exchange of knowledge.

Eating locally and developing an urban-rural food continuum is a rapidly evolving movement. Integration of multi-functional forms of agriculture - termed New Forms of Urban Agriculture (NFUA) - could be a critical adaptation to strengthen this movement and for the sustainability of cities. While NFUA have the potential to provide diverse benefits to humans, there is an absence of reliable empirical data on the scale and impact of urban resources on NFUA which has a profound impact on its viability and sustainability. In this book, we shift the focus from how NFUA have potential to impact the urban system to investigate the potential impacts of urban resources on NFUA. Access to resources such as land, labour, clean water, etc. are major barriers to enter the agriculture sector in the cities; the chapters in this book present projects or reviews recent research on the subject from different cities in the world. This edited volume offers critical perspectives from diverse disciplines, expertise, and geographic contexts related to the actual and potential role of urban and peri-urban agriculture in the developing and the developed world where forms, adaptations, and debates around NFUA vary distinctively. Using and urban ecology lens, the book provides empirical evidence of how urban resources of land, water/waste, labour, and biodiversity impact NFUA.

In Ontologies and Natures: Knowledge about Health in Visual Culture, Fernando Gonzalez Rodriguez argues that visual culture offers insights into how societies perceive the role of nature in their own and others' pursuits to cure and care for the human body. By using a set of visual surfaces and artefacts as entry points-such as vlogs, toys, cosmetics, psychotropics, stamps, posters, and animation, among others-the book sheds light on the evolution, circulation, and rootedness of ideas about nature as a healing source. The first part of the book considers how visual culture operates as a vehicle to diffuse, transmit, mediate, and communicate health-related knowledge and imaginaries about the role of nature in medicinal therapies (e.g., a dictionary). The second part explores the process by which nature becomes a consumable, encapsulated in objects defined by their visual and material traits. The author focuses on items such as labels on packages of herbal cosmetics and infographics about superfoods. In the third part, Gonzalez Rodriguez examines the situatedness of health within two physical contexts: geographical and mental. Methodologically, the book is informed by historical sources, visual-virtual ethnography, content analysis, and semiotic-linguistic analysis of objects from all corners of the globe, paying particular attention to Indigenous traditional knowledge(s).
Human demand for energy has grown multi-folds in recent years. This is the result of rapidly increasing human population, which, in turn, has resulted in increased organic (petroleum) and inorganic pollution on the biosphere. Due to this, we are now facing a number of challenges to sustain life on earth. For example, the increased organic and inorganic pollution in our environment is leading to loss of biodiversity, degradation of environment and thus ultimately causing food insecurity. In this situation, it is imperative to keep updated ourselves with advances on the effects of pollutants, tolerance mechanisms and the potential of different plants and microbes in removing these pollutants from the environment. For this purpose, we invited a number of scientists worldwide to review the current scenario of the problems, current development, and future prospects of the challenges and their solutions in an International Conference on ''Plants and Environmental Pollution'' held in KAYSERI, TURKEY from 6-11 July 2009. The output of this conference has been summarized in the form of this book.
In the marine environment, single-celled, microscopic, plant-like organisms naturally occur in the well-lit surface layer of any body of water. These organisms, referred to as phytoplankton or microalgae, form the base of the food web upon which nearly all other marine organisms depend. Algal bloom is a rapid increase in or accumulation of the population of about 300 species of algae due to excess nutrients (eutrophication), and is of major global interest as it causes reduction in species diversity, abrupt changes in water quality, and discoloration of the water (green, yellow, brown or red) depending on the species of algae and the type of pigments they contain. Dying blooms can also be an environmental concern as when the cells sink and decay, bacteria break down the organic material, which in turn strips oxygen from the water. This microbial oxygen demand at times leads to very low oxygen levels in the bottom waters, harming aquatic life. Documentation of this sporadic high abundance of algae, together with the significant species richness of the diatoms, requires comprehensive studies in the Sundarban coastal environment, which is facing severe degradation due to natural & anthropogenic stressors. In addition, a better understanding of the effects of algal blooms on seafood quality, the complex biological, chemical and physical interactions and subsequent effects on trophodynamics is needed to develop strategies for effective coastal zone management. The book discusses the occurrence of harmful algal blooms (HABs) caused by the dinoflagellates of the genus Alexandrium and Karenia, or diatoms of the genus Pseudo-nitzschia, which have large and varied impacts on marine ecosystems (such as large-scale marine mortality events that have been associated with various types of shellfish poisonings) depending on the species involved, the environment where they are found, and the mechanism by which they exert negative effects. HABs represent a major environmental problem in all regions of the U.S., and their occurrence is on the rise due to increased nutrient pollution. HABs have severe impacts on human health, aquatic ecosystems, and the economy. Such blooms, known colloquially as red tides due to their red or brown hues, are increasing in frequency and magnitude worldwide as a result of changes in oceanic climate, increased coastal eutrophication and enhanced long-distance dispersal in ballast water. As such, the book offers an in-depth account of the complex biological, chemical and physical interactions of the algal blooms (both innocuous and harmful ones). It also discusses the highly topical issue of the impact of global climate change on the frequency and severity of HABs in the context of alterations in temperature, stratification, light and ocean acidification. Focusing on both basic and applied limnology, this book is a reliable and up-to-date reference resource for students, teachers and researchers engaged in the field of coastal research/management at regional and global scales.

As radiological residue, both naturally occurring and technologically driven, works its way through the ecosystem, we see its negative effects on the human population. Radionuclide Concentrations in Food and the Environment addresses the key issues concerning the relationship between natural and manmade sources of environmental radioactivity, their transportation through the ecosystem, and the subsequent radionuclide concentrations in foods and the human population. The book discusses the negative effects of environmental radioactivity on plants and animals, as well as the effects of radiocontaminated food on human health, and perspectives for transfer prevention. Beginning with the fundamentals of matter and the behavior of particles, the text lays a solid foundation for discussions on the source of radionuclides and their concentrations in air, water, and soil. Using predictive modeling, the authors examine the transfer of radionuclides through ecosystems and their effects on individual substances. The book provides up-to-date information on monitoring programs and legislation, detailed descriptions of detection systems, and evaluations of safety protocols in radioanalytical laboratories and in food processing. The authors devote considerable attention to the nuclear and radiological terrorist threat, illicit trafficking and masking of radioactive materials, event scenarios, and radiological forensics.
