Book Description
Among various water and wastewater treatment technologies, the adsorption process is considered better because of lower cost, simple design and easy operation. Activated carbon (a universal adsorbent) is generally used for the removal of diverse types of pollutants from water and wastewater. Research is now being directed towards the modification of carbon surfaces to enhance its adsorption potential towards specific pollutants. However, widespread use of commercial activated carbon is sometimes restricted especially in developing or poor countries due to its higher costs. Attempts are therefore being made to develop inexpensive adsorbents utilizing abundant natural materials, agricultural and industrial waste materials. Use of waste materials as low-cost adsorbents is attractive due to their contribution in the reduction of costs for waste disposal, therefore contributing to environmental protection. This e-book explores knowledge on recent developments in adsorbents synthesis and their use in water pollution control. This handy reference work is intended for researchers and scientists actively engaged in the study of adsorption and the development and application of efficient adsorption technology for water treatment. This e-book covers a wide range of topics including modeling aspects of adsorption process and the applications of conventional and non-conventional adsorbents in water remediation emphasizing sorption mechanisms of different pollutants on the adsorbents.

Book Description
Advanced Oxidation Technologies (AOTs) or Processes (AOPs) are relatively new and innovative technologies to remove harmful and toxic pollutants. The most important processes among them are those using light, such as UVC/H2O2, photo-Fenton and heterogeneous photocatalysis with TiO2. These technologies are also relatively low-cost and therefore useful for countries under development, where the economical resources are scarcer than in developed countries. This book provides a state-of-the-art overview on environmental applications of Advanced Oxidation Technologies (AOTs) as sustainable, low-cost and low-energy consuming treatments for water, air, and soil. It includes information on innovative research and development on TiO2 photocatalytic redox processes, Fenton, Photo-Fenton processes, zerovalent iron technology, and others, highlighting possible applications of AOTs in both developing and industrialized countries around the world in the framework of “A crosscutting and comprehensive look at environmental problems”. The book is aimed at professionals and academics worldwide, working in the areas of water resources, water supply, environmental protection, and will be a useful information source for decision and policy makers and other stakeholders working on solutions for environmental problems.

Book Description
The deterioration of water quality and unavailability of drinkable water are pressing challenges worldwide. The removal of toxic organic and inorganic pollutants from water is vital for a clean environment, as a response to water scarcity. Adsorption-based water technologies are among the most widely used because of their high efficiency and low cost, without relying on a complex infrastructure. In recent years, carbon nanomaterials (CNMs), such as graphene and derivatives, carbon nanotubes, carbon nanofibers, nanoporous carbon, fullerenes, graphitic carbon nitride, and nanodiamonds have been extensively exploited as adsorbents due to their extraordinary surface properties, ease of modification, large surface area, controlled structural varieties, high chemical stability, porosity, low density, ease of regeneration, and reusability. This book provides a thorough overview of the state of the art in carbon nanomaterials as they are used for adsorption applications in water purifications, as well as addressing their toxicological challenges. This volume primarily explores the fundamentals of adsorption, its mechanical aspects, synthesis and properties of CNMs, and adsorption performances of CNMs and their nanocomposites with organic and inorganic materials. Structural engineering and activation processes produce materials with enhanced adsorptive properties and separation efficiencies. Furthermore, the formation of CNMs with 2D and 3D macro-and microstructures and high porosities is a potential approach to improve adsorption performances and extend CNM use at the industrial level. The book also addresses important issues regarding these adsorbents that potentially affect future research and industrial applications of carbon-based nanoadsorbents in water security. - Presents advances in multifunctional 3D superstructures of carbon nanomaterials and their composites for adsorption applications - Outlines the fundamentals on synthesis and characterization techniques of carbon-based nanostructures and their composites - Assesses the major toxicological challenges in using nanostructured materials as adsorbents for water purification

Book Description
The increasing use and the continuous development of pesticides are required to maintain sufficient global food production. The pesticide residues and their biotic and abiotic breakdown products may be harmful to the environment and may leach into waterways, thus it is crucial that the interactions of pesticides with microorganisms are deeply understood at all levels. Pesticides reach the soil via direct and indirect routes. The fate of the pesticides in the soil is affected by chemical, physical and microbiological factors. Microbial degradation of pesticides in soil is possible owing to the diverse metabolic capabilities of the microorganisms present, thus indigenous microbes act as biocatalysts for the remediation of the pesticides from the environment. The research topic will cover novel insights into microbial pesticide degradation with specific attention to the microbe-pesticide interactions in soil. To date researchers have focused on the degradation of pesticides using indigenous microbes with different degradation rate. There is scant information about the degradation intermediates, metabolic pathways, enzymes and complete set of factors involved into the microbes inhabiting into the pesticides contaminated soil. Therefore this Research Topic aims to contribute to the understanding of the role of microbes in pesticide degradation in soil. Since pesticide exposure may result in stress responses in the microbial population of the soil, there is also a need to know about the impact of pesticides on the microbial cell structure, membrane transporters, cellular content, metabolic pathways and gene expression. We are interested in reports of novel metabolic pathways, expression of the key genes in response to pesticide exposure and the changes in microbial physiology caused by pesticide exposure. The removal of the pesticides from the soil requires smart microbial methods that can reduce the pesticides concentration in a short time. The development of the smart bioremediation methods includes the direct application of the potential screened microbial strains and their enzymes. The immobilized microbial strains and their enzymes can be used for the rapid removal of the toxic pesticides from the soil environment. In addition, engineering of the microbial consortia can be developed as the potential smart bioremediation tool. Papers on single isolates or microbial communities are welcome as are reports of novel genes, enzymes or metabolites that might be used as markers of soil contamination. We would especially welcome manuscripts describing the application and development of smart soil bioremediation approaches that could be beneficial for the treatment of large scale contaminated agricultural and industrial soils. The research topic is of immediate interest to scientists and policy-makers and Frontiers in Microbiology is an ideal forum for a collection of novel, high-impact reports. The following themes are welcomes but not limited to: • Novel advancements into the microbe-pesticide interactions to clean the pesticide contaminated soil • High throughput screening of the potential bacterial, fungi and algae strains for the removal of pesticides from the contaminated soil • Smart soil bioremediation using indigenous microbial cultures and their purified enzymes • Microbial enzymes a smart tool for bioremediation of the soil • Engineering of the microbial consortia for the complete pesticides removal and resource recovery
