Editors and Contributors
This volume is the collaborative effort of a distinguished group of editors and contributors from various scientific and engineering backgrounds. Their collective expertise ensures a thorough exploration of the many facets of metal pollution and environmental management.
Chapter 1: Metal Research Trends in the Environmental Field
Authored by Yuh-Shan Ho and Mohammad I. El-Khaiary, this opening chapter sets the stage by analyzing contemporary research trends related to metals within the environmental sciences. It surveys scientific literature and identifies emerging themes, methodological innovations, and key focus areas in the study of metals in ecosystems.
Chapter 2: Toxicity and Sources of Pb, Cd, Hg, Cr, As, and Radionuclides in the Environment
Ghinwa M. Naja and Bohumil Volesky delve into the sources and toxicological profiles of several highly hazardous metals and radionuclides, including lead (Pb), cadmium (Cd), mercury (Hg), chromium (Cr), arsenic (As), and radioactive substances. The chapter discusses their occurrence in the environment, pathways of human exposure, and the significant risks they pose to health and ecosystems.
Chapter 3: Environmental Behavior and Effects of Engineered Metal and Metal Oxide Nanoparticles
Bernd Nowack explores the emerging field of engineered metal and metal oxide nanoparticles, focusing on their environmental fate, transport, and biological effects. This chapter highlights the complexity of assessing nanoparticle behavior in natural settings and addresses concerns about their long-term ecological impacts.
Chapter 4: Heavy Metal Removal with Exopolysaccharide-Producing Cyanobacteria
Roberto De Philippis and Ernesto Micheletti introduce an innovative biological method for heavy metal removal, involving exopolysaccharide-producing cyanobacteria. They explain the mechanisms through which these microorganisms immobilize metals and discuss their potential applications in bioremediation technologies.
Chapter 5: Environmental Geochemistry of High-Arsenic Aquifer Systems
Yanxin Wang and Yamin Deng examine the unique geochemical processes responsible for the development of high-arsenic groundwater systems. They describe the factors that mobilize arsenic in aquifers and explore the health hazards associated with arsenic-contaminated drinking water.
Chapter 6: Nanotechnology Application in Metal Ion Adsorption
In this chapter, Xiangke Wang and Changlun Chen discuss how nanotechnology is revolutionizing the field of metal ion adsorption. They review various nanomaterials designed for efficient removal of metal ions from contaminated water and soils, evaluating their performance, mechanisms, and future prospects.
Chapter 7: Biosorption of Metals onto Granular Sludge
Authored by Shu Guang Wang, Xue Fei Sun, Wen Xin Gong, and Yue Ma, this chapter presents biosorption techniques using granular sludge as a sustainable method for metal removal. It highlights the sorption capacity, operational parameters, and regeneration possibilities of biosorbents.
Chapter 8: Arsenic Pollution: Occurrence, Distribution, and Technologies
Huijuan Liu, Ruiping Liu, Jiuhui Qu, and Gaosheng Zhang offer a detailed survey of arsenic pollution, emphasizing its occurrence across different regions and the technologies available for mitigation. The chapter assesses treatment methodologies like adsorption, oxidation, and membrane processes, providing comparative evaluations.
Chapter 9: Treatment of Metal-Bearing Effluents: Removal and Recovery
Ghinwa M. Naja and Bohumil Volesky return to address strategies for treating effluents laden with metals. They focus on both removal and resource recovery, advocating for sustainable methods that minimize waste and promote circular economy principles.
Chapter 10: Management and Treatment of Acid Pickling Wastes Containing Heavy Metals
Lawrence K. Wang, Veysel Eroglu, and Ferruh Erturk tackle the problem of acid pickling wastes generated from industrial processes. They describe treatment techniques, regulatory considerations, and practical approaches for reducing the environmental impact of these highly acidic, metal-rich wastes.
Chapter 11: Treatment and Management of Metal Finishing Industry Wastes
Nazih K. Shammas and Lawrence K. Wang discuss waste management challenges specific to the metal finishing industry. The chapter outlines processes for treating plating wastes, sludges, and wastewater, emphasizing compliance with environmental standards and waste minimization strategies.
Chapter 12: Recycling and Disposal of Hazardous Solid Wastes Containing Heavy Metals and Other Toxic Substances
Lawrence K. Wang explores the recycling, disposal, and treatment options for hazardous solid wastes containing metals and other toxins. The chapter stresses the importance of safe disposal methods, material recovery, and risk reduction to protect public health and ecosystems.
Chapter 13: Management and Removal of Heavy Metals from Contaminated Soil
Nazih K. Shammas offers strategies for the remediation of soils polluted by heavy metals. The chapter reviews traditional and emerging soil decontamination techniques, including soil washing, stabilization, and phytoremediation, and evaluates their effectiveness under various conditions.
Chapter 14: Remediation of Metal Finishing Brownfield Sites
In this chapter, Nazih K. Shammas focuses on the rehabilitation of brownfield sites impacted by metal finishing activities. He discusses site assessment, cleanup technologies, regulatory frameworks, and the challenges of restoring sites for safe reuse.
Chapter 15: Control, Management, and Treatment of Metal Emissions from Motor Vehicles
Rajasekhar Balasubramanian, Jun He, and Lawrence K. Wang close the book with an examination of metal emissions from motor vehicles. They analyze the sources of metals such as lead and platinum in exhaust emissions, and propose technologies and policies aimed at reducing vehicular contributions to metal pollution.
